Automotive Compression Moulding

Compression molding is one of the leading forming techniques used to produce automotive parts. It is routinely deployed for intensive batch production of car interior fittings using thermosetting composite materials. Semi-continuous compression molding (CCM) is ideal for auto-engineering as it enables rapid, high-throughput turnover of custom-shaped profiles in comparatively large formats. Parcel shelves, for example.

4x Longer Lifetime

One of our partners had come to us to discuss their process requirements. The partner, a part manufacturer in the automotive industry, had been experiencing issues with sticking and mold contamination. After reviewing the situation, we offered our abrasion-resistant and hard-wearing VERSIV^™ SP010-2 X PTFE release belt.

The belt lasted four times as long as the previous component, contributing to tangible improvements to the bottom line. By switching to the VERSIV^™ release solution, our client realized the benefits of maximizing production throughput and productivity in their compression molding workflow.

The Need for Release Solutions in Compression Molding

One of the challenges of compression molding is that the process can often result in problems with cleaning or contamination. Due to the inherent combination of heat and pressure, polymeric substrates may stick to reusable molds. This can affect the part finish, contribute to failure, and necessitate more significant maintenance requirements. Hence the need for intermediary release solutions.

VERSIV^™ Release Solutions for compression molding include high-performance process conveyor belts and sheets which are chemically inert and non-sticking across a wide temperature range. Comprised of polytetrafluorethylene (PTFE), our release solutions are designed to protect molds from aggressive compounds while extending the life cycles of conveyors, maximizing production throughput and productivity.
