Proprietary composite formulations and technologies prevent voids and produce high-quality cores that withstand stringent electrical testing and end-use manufacturing stresses such as thermal overmolding and mechanical crimping.

The mold is then opened and the core plate is rotated and the second material is injected from the secondary rubber system. If the part requires the use of thick sections, they should be cored out to minimize shrinkage problems and to reduce the part weight and cycle time. Properly designed deep undercuts however are possible with GLS over-mold compounds if an advancing core is used when the mold opens and the part does not have sharp corners and the elastomer is allowed to deflect as it is ejected.
