Plastic injection process
We guarantee the highest standards of quality in our plastic injection process.
The thermoplastic pellets, 2 to 3 mm in diameter, are carefully sucked into a hopper and then heated to high temperature. The molten, malleable material is then injected into the mold, selected according to your specifications.
Our high-precision injection molding machines apply high pressure to allow the plastic to spread evenly in the mold, giving it its final shape. In just a few seconds, the part cools and solidifies, ready to be ejected into a collection tray.
Integrating an automated system into our plastic injection process enables us to minimize production costs, increase productivity and offer you exceptional value for money. Thanks to our technical approach, we are able to produce high-quality plastic parts at a sustained rate, without compromising on precision and reliability.

FAQ | Plastic injection molding
Plastic injection molding is a manufacturing process used to produce plastic parts. It involves injecting molten plastic into a mold, where it cools and hardens to form the final part.
The plastic injection process begins with the heating of plastic granules in a cylinder of the injection machine. A metering screw pushes the molten plastic at high pressure into a cavity-shaped mold. After cooling, the molded part is ejected from the mold.
A wide variety of plastics can be used, such as polypropylene (PP), polyethylene (PE), polystyrene (PS), polyurethane (PU), polycarbonate (PC) and many others. The choice of plastic depends on the characteristics required for the final part.
A plastic injection molding machine consists mainly of three key components: the injection system (comprising cylinder, screw and nozzle), the mold (which defines the shape of the part) and the clamping system (which holds the mold firmly in place).
The steps in the plastic injection process include closing the mold, injecting the molten plastic, cooling and solidifying the plastic, opening the mold and ejecting the molded part.
Plastic injection molding is widely used in many industries, such as automotive, electronics, household appliances, toys, packaging, medical, aerospace, among others.
Some important factors include mold design and optimization, choice of appropriate plastic, control of process parameters (temperature, pressure, injection speed, etc.), and quality control throughout the production process.
Some of the limitations of plastic injection molding include the high initial cost of creating the mold, and the time needed to make the mold.
