To provide optimized quote for a mould or parts production, it is necessary to know the end use function of the part, if aesthetic or technical requirements are needed, production volume, and injected plastic material reference.

It is also important to define the tool lifetime, if applicable regulations, and whether it is a prototype, low-volume production, or high-volume production tool.

For a more precise analysis, we recommend providing 3D part files or 2D drawings, Plastic material shrinkage, target cycle time, injection machine details, and any specific process requirements.

A technical template can be used to facilitate the recollection of this information.

The injection point and system are determined based on the plastic material, part geometry, aesthetic requirements, and needed cycle time.

The goal is to ensure balanced filling to prevent defects. For complex or multi-cavities parts, hot runner systems are commonly used, while tunnels or submarine gates are employed when the geometry allows it.

The final decision is validated through CAE filling simulations and processing experience.

Mold cooling is essential for part dimension stability and cycle time reduction.

A uniform temperature prevents warpage, improves repeatability, and optimizes cost per part.

The design of the cooling lines is linked to the plastic material, part finishing and possible mechanical specifications.

The ejection system is designed to apply balanced ejection forces on all the areas of the part, preventing deformation and marks.

The ejectors are correctly sized, and specific solutions are used for delicate parts, such wide bearing surfaces.

Furthermore, the ejection system is guided and balanced to prevent premature wear and ensure reliable operation.

The molds are manufactured using steels and materials selected according to production volume, injected polymer type, working conditions, and finishing requirements.

Pre-treated, tempered, or stainless steels could be used, as well as high-conductivity alloys for specific applications.

Heat treatments or coatings are also applied to increase resistance of wearing areas and improve its lifetime.

An injection mould requires a specific maintenance program dedicated to its design and operating conditions.

This includes cooling lines cleaning, lubricating the mechanisms, checking clearances, “O”rings inspection and substitution, verifying the ejection system and general fitting.

Proper maintenance extends the mould lifetime and ensures part quality.

Specialized companies like Dicomol can define customized maintenance programs based on the mould design and plastic material processed.
