Our plastic injection molding service allows you to reduce the costs and lead times of your pre-production and prototype parts, using our single or multi-cavity steel molds. Take advantage of our expertise and responsiveness in injection molding to produce your prototypes, choosing the material and finish of your choice.
Plastic injection molding is a process for producing plastic parts from steel molds. This production technique involves heating a polymer in granular form until it becomes sufficiently viscous to be injected into the mold. Once injected, the material cools and hardens in contact with the heat-regulated steel, creating a rigid part. The first validation parts allow you to check the conformity of the mold before production.
Injection materials:
Rigid plastics
Flexible plastics
Silicones
Compression Materials:
Overmolding:
General tolerances:
Ultrasonic welding
