  1. Introducing BMC Controls Ltd

  2. Founded 1980 to sell and support Moog parison programming systems

  3. We started producing bottle leak testers (by accident) in 1985 which also led to producing a range of related automation products

  4. Parison Programming Systems BMC CONTROLS Denes B Hunkar, Inventor of the Electronic Parison Programmer, Internal parison cooling, Closed loop control of moulding processes

  5. 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

  13. 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

  14. 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

  15. 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
