Our injection molding capabilities

Name Description
Rapid tools Normally 1-3 weeks to get tools done. Molds with aluminum inserts with a life time of up to 20,000 shots.
Production tools Normally 4-6 weeks to get tools done. Tool life 100K-300K shots or more as per your request.
Single cavity molds Molds containing only one cavity, producing one unit per run.
Molds with side-action cores Cores slide out of the part from the side before it is ejected from the mold. This allows for undercuts to be molded.
Multi-cavity molds Multiple identical cavities are machined into the mold tool. This allows for more parts to be produced per shot, minimizing the unit costs.
Family Molds Several parts are designed into the same mold tool. This allows for the minimization of tooling costs.
Insert molding Inserts are placed into the mold and molding occurs around them. This allows for inserts such as helicoils to be molded in your design.
Overmolding Premade parts are placed into the mold to mold over them. This allows for multi-material injection molding.
