Putting the design of a new product idea that is going to be manufactured on paper (sketches) and in 3D drawings (computer-aided design) is usually not sufficient to confirm all aspects of the design. Before proceeding to tooling fabrication, certifications, component purchasing, and manufacturing, you will certainly need to make physical renderings by doing prototyping in China.

Getting started with prototyping
You might start with a 3D printed rendering (to confirm the overall aspect and size) and/or with a rough ‘proof of concept’ to confirm a key functionality. Then, you will probably need to make look-alike and work-alike prototype.
Here is a simplified view of that process:
Which type of prototyping company is better for my needs?
You need to understand what type of value you need your prototyping supplier to provide. Let’s assume you already have the drawings, schematics, etc. What is your need?
- ‘Just do it’ — most prototyping companies receive CAD drawings and a material spec, and produce some parts, without critical thinking. That’s what you can expect of most “rapid prototyping” companies because it goes straight from input into output. This is great if all you need is 1 or 2 components to play with, for a proof-of-concept.
- ‘Review, provide suggestions, and then do’ — all designs, even if they were prepared by an experienced person, need to be reviewed and challenged (it is a ‘Design for Manufacturing” review). The prototyping process is actually part of the validation of the product design. If you expect this type of assistance, you need to assess the prototyping service provider’s engineering capability. This is important for the final prototype, especially for a full product that includes many parts.
- ‘Review, suggest, do, but also check and test’ — In addition to the above, they translate your requirements into specifications and test plans, they organize those tests on the full product, and they provide their suggestions on how to get better performance/reliability. This is what you can expect from a full-blown R&D center.
In addition, you may want to know what processes they have in-house. It is very common for prototyping companies to rely on a network of subcontractors, and this may create intellectual property (IP) control issues.
You will also see that many companies do prototyping but also manufacturing. If they are upfront about their business model, and if you sign a clear agreement that indicates you will own all the IP, that’s fine. Otherwise, make sure you don’t end up working with an OEM or ODM that doesn’t want to send you the latest versions of the drawings and schematics, doesn’t want to tell you where they sourced the parts…
Here is our list of companies that provide prototyping in China. They mainly provide similar services, for example, ‘CNC machining’ and ‘plastic injection molding’ are pretty universal amongst them, however, some provide design support on the R&D side and some also provide PCBA services for electronics manufacturers looking for a more turnkey approach, so they will be categorised accordingly:

How to get a high response rate when asking for help to get a prototype made?
- Getting down to a clear concept, with documented requirements etc.
- Industrial design
- Some electronic and/or mechanical design work, to get the product to perform its function
- In some cases, a large amount of work to get the product to look good, too
That means they may be shocked when they discover the full cost of making a works-like and looks-like prototype.
In addition, the fact that they want to wait until they have a prototype in hand to start doing a structured market research exercise is a bad sign. Experienced teams start with that.
All this is proof that they are not very experienced and prototyping companies in China know it. It is probably their first time designing and developing a new product. Looking at the statistics of startups that make it all the way to a commercially successful product, the odds are relatively low…way below 50%.
