Elastomer | FIT Additive Manufacturing Group

WHY FIT?

35 years of professional experience as a specialist manufacturer of molded rubber parts.
Our products stand out by precision and highest quality standards.
Elastomer parts can be manufactured in a high diversity of hardnesses and colors.
Safe rubber-metal-connections are used to increase the strength of the hybrid parts.
Insert molding is possible, undercuts can be realized via attached parts.

Elastomer manufacturing − description of the process

Vulcanization of rubber is a process of improvement of the rubber properties (elasticity, strength, etc.) by heating it in the presence of sulfur, which results in three-dimensional cross-linking of the chain rubber molecules. The material has to be shaped, either by pressing or casting, before the heating. The tools for molded rubber parts are created by our own tool manufacturing department.

Benefits of elastomer manufacturing

Short lead times (10 − 20 working days)
Use of original series material
High precision
Better part properties than by 3D-printed elastomers
Ideal for small batch manufacturing
Production performance is about 1,000 − 100,000 parts per mold.
