CONTINUOUS COMPRESSION MOULDING MACHINE

Compression molding is a FULL MOLDING and HIGH PRESSURE PROCESS (similar to injection moulding).
Polymer is fully melted into the extruder and fully mixed and homogenized. The pressure applied on each molding station exceeds 400 kg/ cm2.

DISTINCTIVE FEATURES

1
SHORTER CYCLE TIME and therefore higher productivity. The lower extrusion temperature allows the cap to be cooled in the mould more quickly.
2
LESS ENERGY CONSUMPTION due to lower extrusion temperatures. Since the plastic is colder, less energy to cool it is needed.
3
HIGH SPECIFIC DENSITY due to equal moulding pressure and lower temperatures. This provides mechanical properties and a consistency unattainable with injection.
4
CONSISTENCY has become a major issue in beverage bottling where cap-related plant stoppages can no longer be tolerated.
5
EASY AND FLEXIBLE MAINTENANCE due to independent molds. It is performed on spares stacks offline, thus avoiding machine downtime.
6
QUICK COLOR CHANGEOVERS can be completed quickly without having to clean a hot runner, which is absent in the compression process.

CCM - Continuous Compression Moulding Machine

CCM hydraulic rotary presses are specially designed to produce thermoplastic products by means of compression.
A continuous work cycle is carried out, during which the plastic material is fed by a plasticization unit, cut into suitably sized pellets and then inserted inside the cavities.
Compression moulding is already a well known technology worldwide. More than 45% of plastic beverage caps are produced through compression.

COMPRESSION ADVANTAGES:

  • Shorter cycle time and therefore higher productivity
  • Less energy consumption
  • High specific density
  • Fast and ordinary maintenance activities (not runners are missing)
  • Quick colour changeover process
  • Less waste = lower costs

CCMM - Continuous Compresison Multilayer Moulding

The concept is to extrude a flat pellet of multilayer material and insert it into a standard compression mould (not applicable in the injection process).
A continuous work cycle is carried out, during which a flat multilayer pellet is cutted, placed into an open mould, formed into a capsule, ejected into a conveyor belt and real-time inspected.
The structure and positioning of the barrier layer wouldn’t change in the transition from pellet to molded part.
