Between Treviso and Vicenza, we are at the forefront of the evolution of plastic injection moulding.

Quality, process repeatability and cost-effective solutions. Thanks to these features, the injection molding process is one of the most popular technologies, as far as a quick production of large quantities of parts is concerned.

The process begins with the construction of the mould which will produce the desired part. The mould is attached to an injection machine of the right size and provided with connectors.
Before being sucked into machines via automated processes, plastic granules are dried or dehumidificated. The moulding process starts here and, after several distinct phases, the part will be produced.
Injection: the material is melted by means of heater bands and then rapidly injected through lines into a mould cavity.
Hardening of the material: once the cavity is filled, the part still needs further pressure, so that  any air bubbles can be eliminated in order to get a stable structure. The press keeps the polymer under pressure, till it hardens to the configuration of the cavity.
Cooling: the part is kept in the mold as long as the plastic material hardens. In the meanwhile, the press loads further material into a plastification unit in order to prepare for moulding of other plastic parts.
Part  ejection: The tool mould opens and the part is ejected out using ejector pins that can move at different speeds and pressures. As MPS srl operates with Cartesian robots for the removal of plastic parts, the final cooling phase has been improved and operators can quickly and easily perform their tasks.

The moulding sector produces finished parts without further processing. There are several advantages:

  • cost-effective solutions
  • high productivity
  • low post-molding labor costs
  • collaborative robots can be used, in order to guarantee and certify the process
  • production of even very complex technical parts
  • production of  single parts with different materials or different colors (2k or 3k technology) the same press can be used for different moulds and different types of materials.

In compliance with ISO standards, Mps develops and improves its internal processes and certifies all production phases. We have just the latest generation equipments: the hydraulic components are replaced by more powerful electric motors, thus granting several advantages, such as lower costs and lower energy consumption. Sustainability leads our growth and our development, the "green concept" becomes part of our soul as a company.
