CONTINUOUS COMPRESSION MOULDING MACHINE

Compression molding is a high-pressure molding process: the polymer is melted, mixed and homogenized inside a plasticizing unit. A device draws doses of polymer in the exact weight of the product and inserts them into the molds. The pressure applied to each mold can reach values of about 400 Kg/cm2.

ADVANTAGES OF COMPRESSION MOULDING TECHNOLOGY

1

HIGHER PRODUCTIVITY thanks to a shorter cycle time. The lower extrusion temperature allows the mold to cool the cap faster.

2
ENERGY SAVINGS due to the lower extrusion temperature. With less energy needed to heat the plastic, less is required to cool it. 
3
PRODUCT WITH BETTER MECHANICAL PROPERTIES. Because plasticizing occurs at low temperatures and with no hot runner, the raw material maintains its characteristics and product performance is improved.  
4
CONSTANT WEIGHT AND SIZE OF THE PRODUCT is a winning feature of this technology, exceeding the best results of injection molding.  A cooler product exiting the mold means less shrinkage and therefore less size variability. 
5
RAPID, EASY MAINTENANCE thanks to independent molds. Molds are replaced quickly and individually; maintenance is performed at the stand while the machine is operating.
6
FAST, ECONOMICAL COLOR CHANGEOVER. The simplicity of the plasticizing unit and the absence of the hot runner speed up color changeover and considerably reduce waste of raw material during and after color switches. 

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.

CCMM - Continuous Compression 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 cut, 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.
