CCM - Continuous Compression Molding 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 molding is already a well known technology worldwide. More than a half of plastic beverage caps are produced through compression.

ADVANTAGES OF COMPRESSION MOLDING TECHNOLOGY

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

ENERGY SAVINGS due to the lower extrusion temperature. With less energy needed to heat the plastic, less is required to cool it.

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.

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.

RAPID, EASY MAINTENANCE thanks to independent molds. Molds are replaced quickly and individually; maintenance is performed at the stand while the machine is operating.

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.

Slitting & folding of caps

The functional importance of the tamper evident band makes the slitting machine an extremely important piece of machinery.
The possibility of changing the slitting configuration (number of bridges, thickness of bridges, etc..) has an impact on flexibility and on bridges breaking force, thus fulfilling end users requirements.
“Flap” bands in plastic caps help during the capping phase and properly match with the bottle locking ring.
Such bands need a folding process to be performed after the making of the cap.
We provide machines both for scoring operation (SCM), folding operation (FLM) and also for both operation in a combined, cost-effective step (SFM).

SFM12

Caps scoring & folding system (SFM)

This solution provides both the scoring operation and the folding one in a combined, cost-effective step. The possibility of changing the slitting configuration (number of bridges, thickness of bridges, etc..) has an impact, amongst others, on flexibility and on bridges breaking force, thus fulfilling end users requirements. On the other hand, “flap” or “corrugated” bands in plastic caps help during the capping phase and properly match with the bottle locking ring.

SCM12

Caps scoring system

Closure bridges can be made either directly into the mould during the cap forming phase, or by slitting process in a post molding stage. The possibility of changing the slitting configuration (number of bridges, thickness of bridges, etc..) has an impact, amongst others, on flexibility and on bridges breaking force, thus fulfilling end users requirements

Checking and inspecting the tamper-evident band

The PFMC (Pull Force Machine CVS-CUT) performs destructive checks on the cap tamper-evident band.

PFMC

Checking and inspecting the tamper-evident band

The PFMC performs destructive checks on the cap tamper-evident band.
The pull test measures:
• breaking force of the bridges;
• breaking force of the lugs keeping the cap tethered to the bottle neck.

The machine records the measured values and provides a range of statistics. It can work as either a stand-alone unit or on a production line.
The optional CVS-CUT vision system inspects the tamper-evident band before the destructive test. It features a high-resolution line scan camera ensuring a resolution below 0.01 mm.
