Mold Release

Plastics naturally exhibit high friction, which can cause several issues during molding such as high processing temperatures, machine wear, scratching and poor surface finish. Mold release additives are designed to improve your injection molding process by reducing friction, allowing more efficient processing and improving part quality time after time.

The Cargill range of mold release additives offer an effective solution in a range of polymer types and applications. These bio-based additives help to release parts from the mold more easily resulting in higher quality parts, a more efficient process and less waste.

There are many additional benefits to utilizing Cargill’s mold release products. For instance, these products also help improve flow and dispersion of filled polymers, reduce wear on machine from cleaning, and have improved pigment dispersion.

Case Study: Increased output and cost reduction in PP molding

A manufacturer of polypropylene parts for electric showers wanted to increase production output and save costs. They were producing 71 shots per hour but had to use silicone spray as a mold release agent.

The silicone spray was applied inconsistently and was difficult to remove from the surface of the finished parts, resulting in a sticky residue on the part.

IncroMold™ S was recommended for use at 0.5% to eliminate the use of silicone and allow continuous production. The customer found that they were able to produce 82 shots per hour (an increase of 15%), as well as reduce cycle times from 55 to 44 seconds (an improvement of 20%).

By using IncroMold™ S, the customer observed that the improvement in mold release also resulted in more consistent quality parts, fewer rejects and a reduction in pin marks.
