Rotational Molding

Manufacturing parts via rotational molding is a uniquely challenging craft. Issues like pinholes, surface abrasions, and poor finish quality are quite common — and they often lead to high scrap rate and excessive downtime, which can be costly.

The efficiency of your process and the quality of the parts you produce rely on a range of variables, including the condition of your mold, flow of the thermoplastic resin, and matching of your release agent with your process parameters. If optimizing your rotomolding operation, whether it’s producing children’s playhouses or gasoline storage tanks, is your goal, you can leverage Chem-Trend’s years of experience.

Gain process improvements and solve problems like electric static charge interference and pigment swirls while minimizing pre-release and improving flow of material with Mono-Coat® release agents and molding process aids. The Chem-Trend® Flow Promoter can complement these products to help you make a positive impact on the final look of any rotationally molded parts you produce.

Better End Products with Rotational Molding Process Aids

Electric static charge and other common complications can affect the efficiency of your rotational molding operation. Along with time delays, demolding issues, in particular, can affect the quality of the parts you produce, increasing scrap rate and lowering output. Employing Chem-Trend’s molding process aids can help eliminate these and other issues while providing a high-gloss finish.


A Smoother Process with Mono-Coat® Mold Release Agents

A smoother rotational molding process can be achieved by implementing the right mold release agent. Even at high temperatures, you can combat common rotomolding issues like surface abrasion, discoloration, and inconsistent release with Chem-Trend’s line of solvent- and water-based semi-permanent mold release agents.


Fewer Pinholes with Flow Promoter and Surface Enhancer 360° for Rotational Molding

Pinholes and other blemishes often begin in the early stages of your rotomolding process. This happens when molding resins can’t get to the places they are needed, effectively “starving” some areas and leading to blemishes. The combination of an effective release agent and either Flow Promoter or Surface Enhancer 360° can alleviate this common issue, improving the look and quality of the finished parts you produce.


Resin Tack for Superior Resin-Holding for Rotational Molding

One of the solutions Chem-Trend offers for rotational molding is Resin Tack. It is an adhesive spray that adds value to your rotational molding process, specifically for graphic transfers and multicolored resins.
