Vacuum forming of thermoplastic requires moulds which produce accurate, unblemished parts as quickly as possible. This requires a good understanding of appropriate construction, shrinkage, heat transfer and vacuum hole requirements. As with all machinery design, these moulds need to be robust and modifiable to allow future product modifications.
To date, most of PML's experience is in producing liners for refrigerators, however, this technology is appropriate in many industries.
