Engel blows hot and cold to raise product quality

摘要

Injecting against a cold mould wall starts the material solidifying immediately,and intensive cooling of the mould speeds up the process,so that parts may be ejected sooner and production cycles shortened.But while the production increase is desirable,there are downsides to intensive cooling of the mould.Thin walled parts and parts with long flow lengths may be prevented from filling completely as the flow path is blocked by solidified material,and delicate surface structures may not be fully formed.
