Compression moulding 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 moulding (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.
One of the challenges of compression moulding 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 the reusable moulds. This can affect the part finish, contribute to failure, and may necessitate greater maintenance requirements. Hence the need for intermediary release solutions.
CHEMFAB® release solutions for compression moulding 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 moulds from aggressive compounds while extending the life cycles of conveyors, maximising production throughput and productivity.
One of our partners had come to us to discuss their process requirements. The partner, part manufacturer in the automotive industry, had been experiencing issues with sticking and mould contamination. After reviewing the situation, we offered our abrasion-resistant and hard wearing CHEMFAB® 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 CHEMFAB release solution, our client was able to realise benefits of maximising production throughput and productivity in their compression moulding workflow.
