Screen Changers

BD Plast has been dedicated to the production and sale of screen changers for polymer extrusion lines since 1986. Our Manual, Semi-Automatic & Fully Automatic screen changers are designed to ensure maximum performance for every extrusion process.

 

The frequency of screen replacement is vital in achieving the highest degree of cleanliness of polymers. The different ways to replace them and the type of machine used for this activity affect not only the quality, but also the rapidity and cost of the process.

 

Our range is suitable for the production of:

  • Blown or Cast films
  • Flat sheet
  • Pipes and profiles
  • Cable coating
  • Pelletising from polymerisation
  • Masterbatch and compound pelletising
  • Blow and injection moulding
  • Adhesives (hot melt)

BDL Lever Type Screen Changers

 

Simple and reliable, the manual BDL screen changers offer the opportunity to improve performance, at minimal cost, especially on small and medium size extrusion and coextrusion lines. Available with filtering areas from Ø 20 to Ø 120 mm, units are equipped with a self-activating sealing system that allows a safe and leakproof use, up to 800 bar working pressure. The actuation lever, manoeuvrable on three sides ensures a quick movement of the sliding plate.

BDO FT Hydraulic Screen Changers

 

Maximum productivity and customisation to meet the most specific needs. These screen changers operate in combination with a quick change hydraulic power unit allowing the replacement of the filtering media while the extruder is running. Available with filtering masses from Ø 45 to Ø 160 mm. The units are equipped with a cable channel in the bottom that conveys the power cables and thermocouples in a junction box located next to the hydraulic cylinder. This prevents dangerous overheating of the electrical system, ensuring maximum reliability.

BDP manually operated hydraulic Screen Changers 

 

These represent the hydraulic evolution of the manual screen changers and are suitable for the processing of highly sensitive polymers due to the specific temperature control of each filter holder. If necessary, for space or placement reasons, the manual pump can be mounted separately. Available with filtering masses from Ø 45 to Ø 160 mm they are equipped with a cable channel in the bottom that conveys the power cables and thermocouples in a junction box, located next to the hydraulic cylinder. This prevents dangerous overheating of the electrical system, ensuring maximum reliability.
