HVAC doors are typically produced by injection molding two parts that provide structural strength and air sealing performance. In addition to the lighter weight requirement, the material needed to resist warpage after molding, a common issue for thin walled plastic parts. This formulation provided both the processability required for extremely short cycle injection-compression molding, as well as including an additive to stabilize the material when in contact with copper.

Antimicrobial additives work to resist, inhibit and prevent the growth of microbes including bacteria and mold. Because the toothbrushes were molded in both clear and opaque resins, the team had to explore two different avenues—one that preserved clarity and one that retained opacity. Coupled with their ability to be used across a variety of different resins, These antimicrobial additives provided significant value while protecting against microbial degradation, mold and mildew.

Available in a number of different carriers ranging from polyolefins and styrenics to engineering resins: injection molding, blow molding, film and sheet extrusion, PET sheets and bottles, polyolefin films.

Hydrocerol improved productivity up to 20% due to lower cycle times and processability on different injection molding units. Using Hydrocerol with core-back molding technology, a process in which the mold is opened slightly to further reduce pressure and allow the foam core to expand, Avient helped the customer leverage density reduction to lower finished part weight.

The team’s first move - optimizing the molding machine parameters to boost productivity – helped, but it was not enough. The additive concentrate not only reduced cycle times as expected, it allowed the supplier to achieve better flow and mold filling. Improved operational efficiencies: Optimizing the molding machine parameters and adding OnCap CTR reduced cycle time by more than 24 percent.

The addition of Cesa™ Release Additives to polymers during processing helps to prevent parts from sticking to the mold cavity, facilitating their removal which can lead to reduced cycle times and increased productivity. Prevents parts from sticking to the mold cavity Reusable concentrates significantly reduce time spent cleaning extrusion and injection molding equipment.

Two-shot molding increases efficiency, reduces scrap, saves $55,000 annually The company foresaw that integrating this step into the molding process for the saw housing would cut assembly time and overall costs.  Overmolding instead of standalone molding streamlined production and eliminated secondary assembly steps.
