Continuous Screen Changer in Blow-Molding

Because it has no moving parts, HITECH™ screen changers are compact and fit into the confined spaces of blow molding equipment.

• Because of the steady, incremental rate of screen advancement, head pressure and flow rates remain uniform even over the longest production runs.
• With the elimination of melt temperature and melt pressure variations caused by clogged screens, the parison wall thickness and length will not vary. In programming the wall thickness of the bottles, no extra allowances need to be made.
