Abrasive Material Buildup

Abrasive Material Buildup

What it is

Buildup of the material being molded negatively affecting molding performance in terms of heat transfer, part-dimensional properties, cosmetic appearance, and process efficiency.

What causes it

In friction part production, buildup issues are primarily caused by a lack of release barrier causing the material being molded to accumulate on the mold surface or byproducts and residues generated during the molding process. In this case, the current choice of release agent may not be adequate for the process conditions (not suitable for the process temperature, poor film formation, etc.). This may also be caused by application deficiencies (not enough release agent film present on the mold) or lack of physical and/or chemical resistance of the release agent to the material being molded, which then penetrates the release agent film and physically or chemically adheres to the mold.

Solutions

The problem of buildup can lead to significant inefficiencies in your operation and cost you a lot of money in rework, scrap, and wasted resources. Chem-Trend has the knowledge and experience to identify the root cause of the issue and provide your operation with solutions tailored to overcome this typical problem found in friction components manufacturing.
