What the purpose of parison programming? To enable you to distribute the material where you want it, enabling precise control of the wall thickness at virtually any point. BMC CONTROLS Without thickness control With thickness control

Other features of parison programming. Automatic Weight Correction By connecting a “weigh scale” to the parison programmer the die gap can be automatically adjusted to maintain a constant container weight BMC CONTROLS
Other features of parison programming. Automatic Parison Length control A photocell senses the parison length prior to mould close and the die gap is automatically adjusted to keep the parison the correct length BMC CONTROLS
Other features of parison programming. Easy adjustment of container weights and trimming individual heads. Safer – No need to climb up to the machine head or risk burns. Reduction of material oxidation and thus contamination marks during machine shutdown Settings are digitally repeatable BMC CONTROLS
