Prototype tooling manufacturing is a mandatory process for many industries now. With the advancement of technology and the growing demand for new and customized products, the designs are becoming more complex than before.

Often various industries design products that specifically serve their purpose only. Some designs are so complex and need development to work properly that prototype tooling becomes mandatory.

Prototype tooling manufacturing enables companies like automotive, aerospace, medical, or telecommunications to produce the final products’ replica. And then use it for various purposes like examining, marketing, pitching, or showcasing.

There are many aspects of prototype tooling manufacturing that every OEM, ODM, or engineer should know about. In this FAQ guide, we put together all the most necessary information that will help you choose the right manufacturer and ensure the highest product quality.

All you have to do is just scroll down and read the entire guide. And the end of it, let us know if in any way we can help you with anything.

What materials do manufacturers use in prototype tooling?

With the constant growth and development of prototype tooling technology, there are now various materials to use. Manufacturers choose the material according to the final product, suppliers’ requirements, and machine’s needs.

Different methods require different types of materials for tooling. Subtractive methods require different materials than additive methods. For instance, Different 3-D methods require special prototyping wax.

Aluminum is also used widely for its durability and strength. For industries like automotive and aerospace, aluminum is preferred for prototyping. Because they require the prototype parts as close as possible to the final part with great strength.

On the other hand, plastic or more specifically, the thermoplastic material is also a great choice for prototype tooling. Plastic material can be shaped and customized to a great extent, making it a great choice for prototype tooling. Many plastic grades offer a great deal of strength, durability, and machinability as well.

Because of its excellent surface finishing and other features, manufacturers can use plastic for prototype tooling comfortably for various projects and industries. Some of the commonly used plastic materials are polycarbonate, nylon, acrylic, ABS, and so on.

Keep in mind that the material that is used for your project will very much depend on your requirements and design. You can suggest the material for your project too.

In Sunrise Metal, we always consult and discuss with our customers before choosing the material. When you choose Sunrise Metal for your prototype tooling project, you have the flexibility to choose the material or discuss it with us for the best alternatives.

What is the difference in hard tooling vs. soft tooling?

In prototype tooling, you’ll have to carefully decide and choose the perfect method or material for you. If you’re planning to order prototype tooling from China, you might have already encountered this aspect.

Hard tooling: When you need a prototype tooling with tight tolerances and the design is more critical, hard tooling is the way to go. This method can cost more money and take up to more days to manufacture compared to soft tooling. However, when you need a large number of parts and have an intention for functional use, hard tooling is the best option for you.

Although the price seems more expensive for this method, you’ll save money in the long run. With hard tooling, you get the best result for testing and development. It also saves time on the product approval process.

Soft Tooling: This method is very common for their fast production ability and low expense. When you don’t need tight tolerance, have low budget and time, and there is no functional use intent, you can certainly choose soft tooling for your prototype tooling project.

Soft tooling can be a fast method to execute. It has limited capabilities compared to the hard tooling method.

Before selecting the method for your project, understand your needs and requirements. Both these methods are commonly used in the prototype tooling industry. You should consult with the manufacturer first.

What is the difference between production and prototype tooling?

Many people get confused between prototype tooling and production. If you’re ordering for the first time, you might get a bit confused too. Although the process is somewhat similar between these two, there are some fundamental differences. Let’s see what those are:

Prototype tooling: This is the beginning stage of a part of manufacturing. In the prototyping stage, you order a draft version of your product according to the design. To see how the final product will look like.

Prototype tooling is a process that helps you visualize your design and enables you to finalize the design and proceed to manufacture faster. With the help of prototype tooling, you get the prototype in your hand to examine and develop the final design.

Production: After you’re satisfied with your prototype and final design, you move to this stage. Where your parts or products are actually manufactured in batches, unlike prototyping, hundreds or thousands of parts are manufactured in the production process.

Because you already examined the prototype and improved your final design according to that prototype, your final product becomes more error-proof and well-shaped.

Why is prototype tooling extremely necessary before any production?

Before we jump into why it’s important, let’s talk about what is prototype tooling first.

Prototype tooling is a tool that enables manufacturers to create a prototype or replica of your final product according to the design. A prototype is created for a variety of reasons.

Manufacturing is a costly process and often done in hundreds and thousands of units in a single batch. If there are any inaccuracies or miscalculations in the design, all the parts and products manufactured can be unusable.

With prototype molds, we can easily create replicas of the final products with very low costs and lead time. Which will be used in examining and further developing the design. Prototypes mold can help you finalize the design and the suppliers to get the exact measurement and accuracy of the design.

Without prototype tooling, there is little to no room for correction with the final products. Because when the parts are produced, manufacturing companies have very little ability to do something about it. Because it’s already done.

This is why prototype tooling plays a vital role in the production process. If you’re considering placing an order to any manufacturer, you must consider having a prototype tooling process and test the design with your prototypes. In this way, you can save money in the long run by leaving no room for errors.

Types of prototype tooling methods suppliers use in China? And what does Sunrise metal use in manufacturing?

With the rapid advancement of prototype tooling technology, there are multiple options for this now. All have their merits in their own way. The question is, which one is more suitable and beneficial for you.

Although you understand the significance of the process, it might be hard for you to decide which methods to apply. If you’re worried too, this answer will help you with that.

Let’s see some of the commonly used methods for prototype tooling.

Stereolithography (SLA) and selective laser sintering (SLS)

If you have read this FAQ guide, you already know that there are two different prototype-making methods, additive and subtractive.

SLA and SLS are subtractive methods. Because of their quick turnaround time, they are widely used in rapid prototyping. A CAD model is used in SLA for making substantial parts by hardening and curing photopolymer resin.

SLA is faster than the SLS method and great for presentations and fairs or trade shows because parts can be painted or dyed easily and make it more presentable and dressed up.

However, this method can be more expensive comparably and has limited capabilities when it comes to size. You can’t make larger parts or products using SLA.

SLS is a similar additive process to SLA. One of the major differences between these two is that it doesn’t use photopolymer resin as a material. Instead, plastic, glass, or ceramic is used to make the prototype. Which saves the cost and makes SLS cheaper than the SLA method.

Urethane mold method: This is another cost-effective method of prototype tooling that companies use here in China. The name came from its material, polyurethane plastic. This method is a better choice when you need a small number of prototypes.

The finished product is very presentable and great for marketing needs. However, this is not the most popular choice among prototype tooling and slowly, the demand for this method is fading away.

Soft tooling: This is the most preferred method in the injection molding industry. When you need faster lead time and the budget is low, soft tooling can be a great choice for prototype tooling. Soft tooling can produce a large number of units as well. This method is most favorite for its faster lead time and cost-effectiveness.

Hard tooling: Compared to soft tooling, the lead time and expense for hard tooling are much higher. However, there are some benefits you get with this method that soft tooling fails to offer.

With the hard tooling method, you can have high tolerance parts that can be used for testing and functional use. However, the lead time is higher for this method. But when you need complex design parts, being as close as the final product, hard tooling might be the best option for you.

Now that you know all the preferred options suppliers use in China, you might be wondering what methods are used by Sunrise Metal?

You’ll be glad to know Sunrise Metal owns a wide range of machines and tools designed to provide a great prototype tooling service to our customers worldwide.

Rapid prototyping: This is a complete computer automated process that can deliver the result faster than any other methods mentioned above. Rapid prototyping is a method where you can get the highest accuracy with minimal time. That makes it more convenient and a favorite among the buyers.

If you think why rapid prototyping is so widely used and why do we have a very special facility for this, see the facts below:

  • With rapid prototyping. You can place a very small quantity order. The quality will still be to the greatest extent. This is suitable for you, if you don’t need to market the product, only need a small quantity to test and verify the design.
  • In this method, we use the same material and process as mass production. Which lets you feel the actual product. Because of the same material used with the same production process, the parts resemble exactly like the final products.
  • For the same reason, the quality of parts from rapid prototyping and mass production is identical. This is one of the reasons you will love choosing the rapid prototyping method over others. You will have a clear idea of your final product and make changes where necessary.
  • Because of the faster lead time, it allows you to market the prototype faster and let you ahead of your competitors.

What is the MOQ for prototype tooling manufacturing?

While choosing the right prototype tooling company for your business, MOQ is an important factor to consider. Different companies have different policies when it comes to the MOQ. But in general, companies want large order quantities from the buyers.

Often OEM/ODM companies require a small number of products before production. And that could be a problem for a lot of businesses. Because large companies or manufacturers won’t take small quantity orders, and small or new companies will take the order, but often they fail to deliver the perfect products.

Sunrise Metal can help you with any quantity of rapid prototype parts. You could order as low as 1 piece as well as hundreds of thousands of pieces in each order. Sunrise Metal can fulfill all your demand most effectively and efficiently.

How can I get a supplier who can do both prototype tooling and actual production in China?

As you already know, that prototype tooling is one of the beginning stages of the production process. After you’ve made the design, you need to have a prototype ready to validate and develop the final production design.

Often OEM and ODM companies have to work with different companies for different projects like prototype tooling, manufacturing, surface finishing, assembling, etc. If you’ve gone through this, you know choosing different suppliers for various projects is a very hard job to do. Especially keeping the quality intact is very challenging when this happens.

Sunrise Metal offers a wide range of services to provide you an extraordinary one-stop solution for you. Such as rapid prototyping, tooling, die casting, machining, and assembling in house and surface treatments, together with various value-added services. And that will save you a lot of time, effort, and cost.

What are the advantages of prototype mold manufacturing?

Not all the products or designs need a prototype tooling, but for the right products, this is a must thing to do. There are many undeniable benefits and advantages of it. Let’s see some of those:

Saves time and cost: Prototype tooling helps us experience the product’s exact replica before it’s manufactured. It enables us to identify any errors or inaccuracies in our design to be improved and final products are perfect.

Otherwise, if any error occurs with the final production, that could be a disaster and the products could go to wastage, which will cost a lot of money and time to reproduce the parts.

Increase user involvement: With products in hand, customers can give their opinion and feedback for the final product. That can help you redesign and improve the product that you initially planned. It also increases user engagement and your customers will feel more attached to the product. That can lead to a great increase in sales.

Helps develop a better product: When your design is complex and customized, you must order a prototype tooling service. That will help you identify the failings of the design and let you improve the final product.

Prototype tooling enables you to have the ability to recheck the design physically and more thoroughly before the actual production.

Helps with marketing and market testing: When the final product or a new model is yet to be launched, prototype mold manufacturing can be a great start for your marketing or market testing.

With a presentable prototype, you can start marketing for your product long before the production. So when the final product is ready, you already have a handful of pre-orders to serve. On the other hand, it allows you to pitch to your investors about your plan and product.

To conclude, if your product design is complex, or when you’re manufacturing a product or parts that need to be improved or need feedback, prototyping is a must. It will help you achieve the required standard of your final product that you desire.

Which industries need prototype tooling services?

Most of the companies require prototyping tooling service before going into mass production. Especially, the most demand for prototype tooling is in the marine, medical, and automotive sectors.

The reason is obvious. They need high-quality parts or products with high accuracy and quality. The requirements of their parts are very precise and critical. Prototype tooling is extremely helpful for them.

With prototype tooling, these manufacturers can develop and improve their final products. So the production has no errors at all.

Medical industries need their products to be precise and accurate. There is no room for errors if you’re working with medical equipment and parts. For that, they need prototyping more than others to develop and produce the perfect product that matches their requirements.

Similarly, marine industries use prototype tooling for a variety of reasons. Marine industries require unique parts that need to be tested and used before mass production.

In the automotive industries, new models are launched very often. And for this new model manufacturers need to test, develop, and verify the prototype to improve the final product. And a lot of the time automotive manufacturers test the market by presenting the prototype to the market.

What is the basic thing you need to know before ordering prototype tooling from manufacturers in China?

If you’re ordering for the first time, you must know certain things before choosing a manufacturer or placing an order for prototype tooling.

Choosing the right manufacturer: This can make or break your project as it might be one of the most important parts of your production process. When you decide to work with an experienced manufacturer with a proven track record and excellent customer service, half of your work is done. Because most of the time, they will help with every stage of the production process.

Getting the design right: Design is another critical element of the process that needs special attention. You’ll need to have a design that is compatible with CAD and the machines. Make sure that the design works great and free of any errors.

Get the measurements right: The measurements of your products also play a vital role in manufacturing. Ensure that all the measurements are accurate.

Choosing the right process: As you already know, various options are available for the prototyping tooling. You must choose the right one for you. Because for pricing or any other issues, you fail to choose the right process for your project, you won’t get the best results.

Detailed instructions, including tolerances: Remember that you’re the one that has the best understanding of your products. Provide detailed instructions to your manufacturer, including the tolerance level that you want your products to have.

Consider the application: Your prototype tooling can very much rely on the application you have in mind. This can also change the raw material of your prototype tooling manufacture process.

These are some basic and most important things to consider. As I’ve said before, choosing the right manufacturer can help or hurt you in all other factors. So make a better choice by selecting a great one. Check and verify the quality, certifications and track record of the manufacturer before placing the actual order.

Why do manufacturers rely on CNC machining for prototype tooling?

CNC machining is one of the most preferred ways of manufacturing prototype molds. This is a subtractive process that delivers the best result in the prototype tooling industry.

CNC machining for prototype tooling is the most convenient and reliable method among all. In this method, the machine uses a computer-generated 3D design to produce the parts, which makes the measurement very accurate and closer to the final design.

If any error is identified with the design or prototypes with CNC machining, it’s very easy to make changes and make the next prototype error-free. Because the same design can be used for the final product and the similarity between the prototype and the final product is very close.

This method is faster than any other alternatives while providing a great result. Different material options can be used too.

For these reasons, prototype tooling suppliers in China, including Sunrise Metal, rely on CNC machining for most projects. It enables us to provide our customers with great quality products in less time.

How to maximize the similarity between prototype parts and final products?

The goal of prototyping tooling is to make a close replica of the final products. There are different prototyping methods. But when you need the closest match with the final parts, we suggest you choose rapid prototyping.

In this method, we use a similar process and material as the final production. So you can get the product exactly like the finished parts.

Rapid tooling is a completely computer-operated method. It enables us to create prototype parts in a very short time and the quality is very similar to the mass production parts.

How to reduce the cost and waste material in prototype tooling manufacturing?

Cost and wastage are important factors to consider while choosing the right process for your prototype tooling manufacturing process. A very small amount of changes in cost for a large volume of orders can have a significant impact on your budget. Certain elements need to be considered to get the best quality products at a reasonable cost and minimum wastage.

First, you’ll need to communicate with your manufacturer or supplier thoroughly. Ensure both of you are on the same page and understand each other. Consulting with your manufacturer about the cost and waste material is the best way to minimize those. Because they know all the processes and ways for this. All you have to do is make them understand your requirements. And the manufacturer should be able to identify the best option for you.

Second, you need to review your design thoroughly multiple times. Sometimes fixing your design can save you a ton of money and time upfront. Make sure your design is perfect and ready to be manufactured. You can consult with your manufacturing company’s in house designers too for better understanding.

Third, before going into prototype tooling, you can perform simulating testing as well. It will help you visualize the design and identify any errors.

Can sunrise metal make a prototype mold from a part that I already own?

Of course! We often get clients who want us to replicate a product they already own or collected from somewhere. We can successfully make a prototype mold from your part and provide you prototypes that closely resemble your pre-owned part.

If you’re an OEM/ODM company and have a part in hand that needs to be tested and improved, we can help you with that. All you have to do is send us the part and let us know your exact requirements in detail.

After that, we’ll make the design exactly like your parts, and we’ll make prototype molds that will enable you to test and develop the design of your final parts.

Because no one wants poor quality for their business, we work hard to provide the best quality products at an affordable price, so our customers can comfortably grow their business.

Our quality control team checks the quality and inspects all aspects of the products while in production and after production. That eliminates any chance of errors and ensures you’re getting the best results.

If you’re like us and believe in actions, other than words, we welcome you to have a visit to our factories. So that you know who you’re working with and what capabilities do we have.
