Questions and answers

We offer four technologies: stereolithography, thermoplastic injection, vacuum duplication and CNC machining. Generally, we recommend CNC machining if the quantity is fewer than 10 parts; beyond that, the choice will be oriented more towards vacuum casting, which is more relevant since it allows very important economies of scale. Send us your project with as much information as possible and we will refer you to the best process.

3D printing does not always allow good finishes to be obtained or the respect of the mechanical properties of the parts because, unlike CNC machining, it does not always use real materials but rather uses equivalents. In addition, when producing small series, the cost and speed of production of 3D printing is less attractive than vacuum casting. We therefore prefer traditional technologies to manufacture plastic parts, for which the functional and visual aspects are important.

We can paint your parts in colours that are close to any reference colour in the Pantone and RAL ranges.

Your parts are sent to you by plane and arrive within 4 days after completion. We organise our work schedule to be able to send your parts on Friday so you receive them the following Monday.

We work with “100% on order” payment or “70% on order/30% on receipt of parts” depending on the nature of the project. Payment is by bank transfer.

You can go here or send an e-mail to info@prototechasia.com, by sending us the following information about your project: material requested, number of parts, finishes and 2D/3D files in your possession. Upon receipt of these items, we will send you a quote within 24 hours.

Our customers come from various sectors that regularly require plastic prototyping, such as aeronautics, medical, electronics or automobiles. Our partners are mainly consulting firms and R&D and marketing departments.

Small series refers to when a part is produced in several dozen copies.

We have experience in manufacturing large parts of up to 2000 mm.

We possess the main families of machinable plastic materials, as well as the main metals. Concerning polyurethane resins (vacuum duplication), we mainly work with the range of materials made by Axson and Heicast. You can find a complete list of our materials in the “Materials” section.

This varies depending on their geometry, but generally our technologies are financially worthwhile up to 200 copies.

CNC machining, also known as “plastic part milling” or “CNC plastic machining”, involves the machining of plastic parts using a milling cutter and offers the advantage of using the real material. Vacuum duplication or vacuum casting, on the other hand, uses a silicone mould to produce the parts and is generally preferable for quantities exceeding ten copies.

The formats we can use are: IGS, STP and XT.

Normally not, but it depends on the situation.

Prototech Asia is an expert in the manufacture of plastic prototypes that are as close to reality as possible, because we produce your parts from the real material and with the good finish. The parts are thus very similar to the series production, and can be used for functional and visual tests.

Our workshop regularly implements projects requiring engraving, clear polishing, sandblasting, overmoulding, soft touch, chroming, etc. For the full list, please see our subsection “Finishes”.

We can simulate the overmoulding of plastic parts or metal inserts, functional clips, foldable hinges etc. For more information, please click here.

Tell us about your project and we will send you the contact details of the providers we know.

Our workshop works to tenths of a millimetre. However, the difficulties in respecting the dimensions of a part increase with the increasing size of the part.

Yes, we have ABS and PC for machining. For silicone moulding, we have Heicast 8260 resin.
