Molding

Solutions for plastic molding processes

Molding processes require a constant balance between aesthetic quality, production stability, material behavior, and the repeatability of the final result.

From high-precision production to the most complex technical applications, formulation, dispersion, thermal management, and processability directly influence process continuity, surface quality, and the performance of the finished component.

Free Flow supports companies, R&D teams, and production departments in developing solutions formulated to improve material behavior within key molding processes, helping to reduce operational issues, increase process reliability, and expand application possibilities.

What is technology?

Injection molding transforms molten polymer into finished components through pressure and cooling within the mold.
It is one of the most widely used technologies for high-precision, highly repeatable, and high-volume production.

The balance between fluidity, dispersion, thermal management, and material behavior is crucial for ensuring process continuity and consistent part quality.

Why it is used

  • High productivity;
  • Excellent dimensional repeatability;
  • Great geometric freedom;
  • Reduction in cost per piece;
  • Compatibility with engineering and filled polymers;
  • Integration of aesthetics and functionality.

Key challenges

The most frequent critical issues concern:

  • Flow lines and aesthetic defects;
  • Filling instability;
  • Issues with color and additive dispersion;
  • Non-uniform shrinkage;
  • Internal tensions and fragility;
  • Thermal degradation;
  • Difficulty passing stool;
  • Instability in hot runner systems.

In multi-material or overmolding applications, the following also become critical:

  • Adhesion between materials;
  • Formulation compatibility;
  • Aesthetic uniformity across different components.

What to measure

  • Injection pressure stability (ΔP);
  • Average cycle time;
  • Scrap per batch;
  • Color and gloss repeatability;
  • Stability of the fill;
  • Production line OEE;
  • Production continuity and machine downtime.
