Facts about Making Rapid Prototypes in China


Facts about Making Rapid Prototypes in China

When you have a great idea about a new product, you cannot wait to see how well it may be sold in the market. However, it’s risky to invest a bit amount of money to jump to production. In this case, rapid prototypes play a great role.

Businesses have their share of challenges, especially when they’re planning to bring a physical product to the market. Businesses must not only come up with a creative concept that will benefit the market they are entering, but they must also produce a market-ready product, find investors and funds, etc.

Fortunately, today's businesses have access to more tools and services than ever before, making it easier for them to produce innovative products. They benefit in a variety of ways by working with prototyping services.

Rapid prototyping can create samples of your product to evaluate the appearance, function, strength, and manufacturability of the product components. It enables you to identify design flaws early during the product development, so that you can take action to fix them.

Rapid prototyping technology has advanced significantly. It is now less expensive to obtain high-quality prototypes in China.

I. Benefits of making rapid prototypes in China 

Testing market

In the past, quick prototyping was used to determine whether a product was suitable for large production, people would create items, identify any defects, and find solutions. Now, rapid prototypes are more used to determine whether the product will satisfy the market demand.

Saving time 

Tooling is not required in prototype manufacturing methods, which indicates that parts are manufactured immediately. Rapid prototyping has drastically shortened the time it takes to go from product design to product feasibility analysis. Anything that was discovered via this procedure can be swiftly applied to future development.

Saving cost

Making moulds is expensive, and any modifications made to product design require modifications of the moulds, which is also expensive. Using rapid prototyping during the development stage saves money by avoiding the need to redesign the manufacturing moulds.

Reducing risks

Mass production requires strict quality control due to the potential impact that even a little manufacturing error can have on an entire batch of defective goods. Quick prototypes enable extensive physical analysis at an early level, enabling developers to test for flaws and make useful modifications before significant production issues arise.

Keeping versatility

If there are any issues with the product style, entrepreneurs will simply return to the planning stage, adjust the CAD file, and have a new prototype built. This can be an advantage because it gives companies the freedom and ability to improve their product and launch the product at right time in the market.

II. Major Rapid Prototyping Technologies in China

3D printing 

3D printing is an additive manufacturing process, where the requested prototype is created by layering many components together. Due to its great accuracy, low cost, and material compatibility, it is the most popular technology for making quick prototypes in China.

CNC machining

It is a technique used by prototyping services to ensure that visual and functional parts of the product are assembled in a manner that is similar to the original elements. As you know, getting parts constructed with the required materials is essential to verify your design.

This technology is suitable for the common machined materials, including a variety of hard plastics, and metals such as aluminium, brass, steel, nylon, ABS, and zinc.

Die casting

Aluminium die casting is appropriate when you require numerous prototypes with a clear layout, smooth sides, and excellent dimensional accuracy. The procedure is basic and straightforward and doesn't require many professionals with specialized skills.

In addition to aluminium, the procedure can also be utilized to create prototypes out of magnesium and copper.

Vacuum casting

This method allows producing plastic parts in a quick way. The polymer material is injected into a tool to create the prototypes. The main benefit of vacuum casting is the tooling is inexpensive. This technique is very useful for the rapid prototyping of plastic parts. Visual and mechanical characteristics are identical to those of commercial elements.

Rapid prototyping technology can generate physical models directly from computer-aided design (CAD) files, greatly shortening the time from design to prototype, which means buyers can see physical samples of their customized products from China in less time, speeding up product development development and launch process.

III. Difference Between Prototypes and Final Products

Material: Prototypes are built of completely different materials than the final products because the material that is used in the final product is either too expensive or too difficult to create. In some circumstances, the ultimate production materials should be in the early stages of development and not yet available for use during a prototype.

Process: Prototypes are made using completely different fabrication techniques than the final product because mass-production technologies are ineffective for producing a small number of components.

Verification: The final product is subjected to quality assurance tests to ensure that it complies with the drawings or specifications. Custom review fixtures, statistical sampling procedures, and other techniques are used for manufacturing larger quantity of final products. Prototypes are often designed with an expectation that some adjustments or work will be done during the fabrication process.

IV. Process of Making Prototypes in China 

1) Design the product yourself so that you have the blueprint and copyrights. Avoid making the error of letting a Chinese manufacturer handle it because they will believe that they are the sole owner of all intellectual property rights. 

2) Verify and confirm that all product components can be created or purchased. That can take some time, depending on how sophisticated the prototype is, but it will identify some of the technical challenges and confirm whether cost targets are reachable.

3) Assemble the prototype once all the components are prepared. Iterations in design and prototype are required at this point to address all issues.

4) At the last stage, take some time to do thorough testing. The urge to start producing as soon as possible is quite tempting, but it is much quicker and less expensive to repair a problem that is found before manufacturing begins.

V. Facts About Chinese Prototyping Manufacturers

Flexibility with cost

While many people believe that Chinese manufacturers are of low-cost, but the fact is that it isn't that cheap at all times. The truth is that Chinese prototype manufacturers will try to work inside your budget, they are flexible of choosing different technologies when constructing a model.

Willingness for cooperation

Chinese manufacturers are far more willing and prepared to take on work and complete it than the native manufacturers. The Chinese market is diverse and caters to a wide range of pricing points, so you'll always find someone eager to take the work that meets your budget and requirements.

Exact replica

Rapid prototyping technology is very suitable for the production of customized and personalized products. For example, when you need custom products made in China, it has more possibilities and flexibility and accelerates the product development process. Copying exact styles from your competitor is unethical, but you can add a few elements of your own and make your innovative piece. For example, if you like the size and work of a specific brand, you can ask your Chinese manufacturer to replicate specific characteristics from the brand and have all different parts made according to your company's style. This gives you a better chance of landing the right style quickly. When buying bulk items from China, rapid prototyping technology provides fast, economical, flexible and high-quality solutions for buyers who need customized products, greatly promoting the development of customized products.


Many companies find that their prototypes are delivered on time and in good condition by Chinese manufacturers. They are hardworking people who always get the job done on schedule. They are adamant about achieving extremely tight turnaround times in a highly competitive market. Your prototype will be consistently delivered on time, which translates into tangible advantages for your business.

Feasibility prototypes

Feasibility prototypes made in China are frequently used to examine certain alternatives that are included later in the designing procedure. These allow designers to improve a design after creating an initial prototype, and they can be used both digitally and for physical models. If a designer discovers that a crucial component of the product is lacking, a feasibility model is built that may be customized as new concepts emerge.

Working model

A working model allows you to test a product's appearance and function to see if it works the way you expect it to. This is useful for automated inventions or various styles with alternatives that demand precise planning or strategy. The idea is to stick to the basic designs to see if the design actually works.


Choosing appropriate rapid prototypes from China is important for creating a successful final product. Different methods have different tools and costs involved. You need a suitable Chinese manufacturer that uses your prototyping concepts, which will help get a smooth business process.When you contact Chinese manufacturers, please be specific about your needs. 

The advantages and disadvantages of outsourcing prototypes to China should be assessed. The huge benefits are lower prices, scalability, and faster turnarounds, the concerns may be intellectual protection, so, you need a trustworthy partner, like a verified sourcing agent, to help you.
