Plastic injection molding

Injection molding, also known as plastic injection, is a process for processing thermoformable materials, including thermoplastics.

This technique can be used to manufacture parts in large or very large series.

Injection-molded components can be found in a wide range of manufactured products, including automobiles, household appliances, IT equipment and garden furniture.

Parts range in size from a few millimeters to several meters (car body parts, garden tables, etc.).

Before processing, the plastic material takes the form of granules rarely exceeding a few millimeters in size.

These granules are transferred inside the plasticizing sheath to be heated and gradually softened to a sufficient temperature to allow the material to be injected under pressure into the mold cavities, giving the final, definitive shape to the manufactured product.

The range of processed thermoplastics is extensive: PP, ABS, PVC, POM, PMMA, PA, PET, PC…Simple or filled range, fiber or glass bead.

All materials, colorants and additives can be studied.

The Gender Equality Index was established by the Law on the Freedom to Choose One’s Career Future. It is a tool designed to calculate the pay gap between men and women.
This index allows companies to assess the level of gender equality out of 100 points. It is calculated based on the following criteria:

  • Gap in pay between women and men
  • Gap in individual pay raise rates
  • Number of female employees receiving raises following maternity leave
  • Parity among the 10 highest paid employees
  • Gap in promotion rates

The VELFOR Group has calculated its Gender Equality Index. For 2024, it stands at 92/100:

  • Pay gap indicator: 37 points out of 40
  • Individual pay increase rate gap indicator: 35 out of 35
  • Return from maternity leave indicator: 15 out of 15
  • High pay indicator: 5 out of 10
