The wall thickness of the substrate and overmold should be as uniform as possible to obtain the best cycle time. Wall thickness in the range from 0.060" to 0.120" will ensure good bonding in most overmolding applications. Prevent the TPE from flashing over areas on the substrate.

He joins PolyOne from Hexion Inc., where he served as vice president, Epoxy Specialties, and delivered significant expansion in sales and profitability. Altice holds a bachelor’s of science degree in chemical engineering from Missouri University of Science and Technology. We also appreciate her service during our first stage of the Spartech integration, and wish her all the best in her future endeavors.”

The part – sourced from a sub-supplier – required secondary work by Mars Otomotiv, including removal of flash, drilling holes and surface treatment to prevent corrosion. They eventually settled on Therma-Tech TT6600-5001EC as the best solution to provide comparable heat dissipation. Today, Mars Otomotiv benefits from the simplified logistics of molding polymer heat sinks in-house – including reduced order lead time, improved on-time order completion and more free-working capital. 

These braces, traditionally made with steel, were initially fabricated from aluminum for a solid weight savings of 3 kg per vehicle over steel versions. For the brace, Avient's engineering team developed and analyzed three options: a unidirectional, hybrid carbon and glass fiber profile; a unidirectional carbon fiber profile; and finally, a profile made with both a unidirectional carbon fiber and a transverse engineered fabric, which had the advantage of minimizing any potential cracks from propagating. Engineers chose this third option because it met all of the technical requirements and had the best combination of properties.

For starters, the insert was made from thermoset silicone rubber – a tried-and-true material that requires a slow-and-costly manufacturing process. The manufacturer needed an overhaul for the part – from a completely new base material to a more efficient manufacturing process. To get help in finding the best alternative material that could be produced faster and more efficiently, the manufacturer turned to Avient.

They also provided mold fill evaluations to evaluate the best injection parameter set up to process Therma-Tech in the respective mold. As a result, Elausa replaced Zamak with Therma-Tech thermoplastics, significantly reducing part weight from 38g to 9g. Due to the success of this project, the new, lighter heat sink made from Therma- Tech conductive thermoplastics has been rolled out across multiple vehicle models.
