BIWI sees prototyping as an important step of project development and offers the following processes:

QuickForm®

■ Vacuum casting in a silicone mould realized from models by stereolithography or machining

■ Enables functional testing ■ Material : resin, Pu ■ Wide range of materials corresponding to

specification (hardness, resistance, etc.) ■ Insert moulding possible ■ Dimensional tolerances: ± 0.05 to 0.1 mm

Quickprint®

■ 3D-Printing process ■ Permits validation of your design ■ Material : resin ■ Realization of complex geometry

and thin wall parts possible ■ Flexible or hard material ■ Dimensional tolerances: ± 0.05 to 0.1 mm

rapid moulding ■ Rapid steel or aluminium tooling ■ Enables moulding with final material ■ Rapid execution ■ Simplied parts design

moulding - insert moulding

With over forty moulding presses, BIWI is an expert in elastomer and silicone moulding and insert moulding.

elastomer (medical grade)

ACM, BIIR, CR, CSM, EAM, EPM | EPDM, FKM, FQ | MFQ, HnBR, nBR, nR, SBR,

insert moulding ■ Perfect adherence ensured between elastomer

and insert due to a mastered chemical treatment

thanks to our know-how in this process, BIWI can propose atypic material association, such as:

■ VulcaMix® : rubber and metal, alloy or plastic ■ VulcaCéram® : rubber and ceramic

BIWI masters the insert moulding even for highly complicated parts
