Modular molds

CEMA changes the multi cavity approach. Modular mold is a patented innovation from CEMA.

True evolution in the multi cavity mold, this technology brings substantial gain for injection process :

  • Compact : increase of cavity number for the same injection press surface.
  • Reliability : Considerable reduction of wearing parts
  • Maintenance : easy rotating maintenance while injection press operating.

All these gains are easy to evaluate and demonstrate.


The modular technology from CEMA is patented and can go up to 128 cavity mold and fit best requirements for cavity molds.

Pratically :

  • Gain from 10 to 15 % for operational efficiency : OEE
  • Capex optimization re-use of investments for pilot and ramp-up phases.
  • Thermal efficiency and cycle time reduction.
  • Improved reliability et maintenance cost reduction.

CEMA received the 2016 APTAR supplier award for excellence

Multi Cavity molds

Technical components

CEMA is specialized in design and manufacturing of molds for technical and precise components for complex mechanical systems :

  • Pumps and valve components for medical or cosmetic applications.
  • Inhaler or counting systems
  • Critical parts for safety devices (injection pens, …).


Precision and repeatability of plastic parts is obtained by

  • precision machining of cavities,
  • but also with a good design and control of regulation circuits.

Qualification is get through parts validation combined with a robust process.

> Precision molds

Quality control and precision machining requires a control over manufacturing process and methods.

All precise machining is done internally.

To achieve this CEMA invest regularly a significant amount to keep its equipment up to date

  • Multi axis milling lathe center with automation,
  • Cylindric and coordinate numerical grinding,
  • EDM wire and forming,
  • Laser welding and graving

The company is also know for its precision and manufactures some work for precise parts in for spatial, nuclear, watch , …

The last operations are finalized with adjustment professionals who have a perfect understanding of the tool functioning and interface requirement with plastic molding.
