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.

INSPECTION SYSTEMS FOR PLASTIC CAPS

As a market leader in the production of compression molding machines for plastic caps, SACMI has developed a complete line of machines and inspection systems. Vision systems and Spark testers are the daily help needed by all cap manufacturers.

The benefits of the profitable digital revolution. Digitalizing processes brings major benefits, as SACMI clearly demonstrates with a presentation of the key 4.0 development areas on its cap and PET preform production lines: SMART PACK, HERE, SMART CARE.

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

Sistema de corte y doblado

Esta máquina realiza tanto la operación de corte como la de doblado en una única solución combinada y económicamente conveniente. La posibilidad de modificar la configuración del corte (número y espesor de los puentes, etc.) repercute, entre otras cosas, en la flexibilidad y en la fuerza de rotura de los puentes con lo cual se satisfacen las exigencias de los usuarios finales. Además, las bandas de aletas u onduladas en las cápsulas de plástico simplifican la fase de tapado y coinciden perfectamente con el anillo de bloqueo de la botella.

SCM12

Sistema de corte

Los puentes de los cierres se pueden realizar directamente en el molde durante la fase de moldeado del tapón o mediante un proceso de corte en una fase posterior al moldeado. La posibilidad de modificar la configuración del corte (número y espesor de los puentes, etc.) repercute, entre otras cosas, en la flexibilidad y en la fuerza de rotura de los puentes con lo cual se satisfacen las exigencias de los usuarios finales.

FLM12

Sistema de doblado

Las bandas de aletas en las cápsulas de plástico simplifican la fase de tapado y coinciden perfectamente con el anillo de bloqueo de la botella. Estas bandas requieren la ejecución de un proceso de doblado que tiene lugar después de fabricar la cápsula

Checking and inspecting the tamper-evident band

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

PFMC

Inspección y control de la banda de seguridad

La PFMC realiza pruebas destructivas en muestras seleccionadas de tapones.
La prueba de tracción mide:
• la resistencia a la rotura de los puentes
• la resistencia a la rotura de los bordes de la banda que mantienen el tapón unido a la botella.

La máquina guarda los valores medidos y proporciona una serie de estadísticas. Puede funcionar de forma autónoma o en una línea de producción.
El sistema de visión opcional CVS-CUT inspecciona la banda de garantía antes de la prueba destructiva. Está equipado con una cámara lineal de alta resolución que garantiza una resolución inferior a 0,01 mm.

Lining for plastic closures

In order to ensure proper sealing and retention of CO2 levels with highly carbonated beverages, we mould a PE/EVA liner into the cap’s shell. For that purpose we have developed two distinct and separate technologies, whose name is self-descriptive: in-shell molding and out-shell molding.
