Our plastic injection molding solutions are specially adapted to the production of prototypes and small series of plastic parts (from 100 to 1000+ parts). Inspired by traditional molding techniques, we inject your plastic parts using an aluminum prototype mold (or rapid tooling). The results achieved with this technique are equivalent to series molds. The robustness, mechanical properties and industrialization information are identical.
The design of our injection rapid tooling is based on a standard ‘mold base’ frame and interchangeable aluminum core and cavity inserts. This reduces the investment costs and production times inherent in plastic injection. This is our rapid production technique which is the most expensive. However, it makes it possible to obtain functional parts made from the ‘right material’. They can be marketed or used in transition production.

What is a prototype mold
The ‘prototype mold’, or ‘rapid plastic injection tooling’ is based on the same principle as series plastic injection molds, but has a simplified and accelerated design. It is also not intended for long-term use. The use of a common mold base and aluminum for the molding parts makes it possible to reduce investment costs and machining time. Production of the prototyping mold takes between 2 and 4 weeks and is 40 to 60% less expensive than a traditional mold. The cost and design time of the mold depends on the shape complexity of the part to be molded. After a complete analysis of your plastic parts, our design office creates the tooling plan of your mold. We then start its production according to your specifications.
Prototype mold for injection molding
This process consists of injecting a molten polymer (thermoplastic material) into the prototype tooling under high pressure. The plastic material is then cooled and solidifies, taking on the shape of your part. This prototyping technique allows the use of a very large range of ‘right material’ resins. The overmolding of metal inserts and the production of parts incorporating two materials is possible.

Uses and applications of prototypes molds
The speed of a prototype with the quality of an injection part
In rapid prototyping, the use of a prototype mold for plastic injection therefore makes it possible to obtain small series using the right material at lower cost and in reduced time. It is a very good solution for testing your concept quickly and cheaply. There is no need to sacrifice the quality of the final part. You therefore obtain reliable information (mechanical, geometric, assembly and industrialization) on the final parts as well as the subsequent production of a series injection mold.
Producing a prototyping mold also serves the following purposes:
- Marketing needs: production of promotional parts, prototypes or pre-series to test a market
- To accelerate a product’s access to its market
- To make the transition to a series production mold during the design phase
- Needs of on-demand production
Application of prototype mold in the field of rapid prototyping
This technique allows the production of small series that are close to reality. The applications of plastic injection molding are very varied. They are particularly useful in the automotive, packaging, medical, and electronics sectors.
Cases, cowlings and hulls are examples of parts that we produce very regularly. In a field that requires many tests and certificates, such as the medical sector, plastic injection can satisfy the regulatory requirements and constraints. (Find out more on our page about standards.)
