If the part requires the use of thick sections, they should be cored out to minimize shrinkage problems and to reduce the part weight.
This is especially true for long, thin parts or parts where the substrate is thinner than the overmold or if a low modulus substrate material is used.
Add stiffening ribs to the substrate part

It also provides accurate control of part packing and densification, which can help prevent sinks and voids in the part.
GLS TPEs have lower viscosity (higher flow) than traditional thermoplastics and will leak back easier than other materials.
Increased density, thus higher part weights.

A leading medical contract manufacturer faced an unacceptably high number of rejected parts for a pulmonary device housing.
The materials exhibited warpage, causing an uneven surface in a substantial number of parts produced.
Without a consistently flat surface, the manufacturer encountered a variety of issues involving both the form and function of the part, leading to the high number of rejected parts.

Since its founding in 2004, the Istanbul, Turkey-based maker of lighting for the global auto and transportation industries had built a good part of its thriving business around LED products.
As part of their search for an alternative, Mars Otomotiv’s engineers met with Avient to explore non-metal options for the part.
Again working in tandem, the Mars Otomotiv engineers and Avient’s technical team were able to alter the mold so it could process the thermoplastic in place of aluminum.
