Manufacturing and Assembly of Injection Molds
The quality of mold manufacturing determines whether a mold performs as intended in production. Mold inserts, slides, cores, and precision fits must be manufactured to work together seamlessly and reproduce the required part geometry with maximum accuracy.
Comprehensive In-House Manufacturing
Our manufacturing capabilities cover every stage of mold production, from machining in the soft state through hard machining and precision finishing. Milling, turning, and grinding are seamlessly integrated with high-speed machining, EDM, and polishing to produce mold inserts, precision fits, and functional surfaces that perform with maximum accuracy after heat treatment.

Frequently Asked Questions About Mold Manufacturing
When is EDM used instead of milling or grinding?
Milling is used for accessible geometries, while grinding provides highly accurate sealing surfaces and precision fits. EDM is applied where conventional machining cannot produce the required features, such as sharp internal corners, undercuts, or intricate details. EDM can also generate specific surface finishes, making it the preferred process when both geometry and surface quality are critical.
Why is mold assembly so important?
Assembly is where all mold components are brought together and verified as a complete system. Slides, ejector systems, and guide elements are adjusted, motion sequences are tested, and parting surfaces are fine-tuned until the mold operates smoothly and reliably.
How are precision fits and functional surfaces achieved?
Precision fits are created through coordinated machining processes such as milling, grinding, and EDM. During assembly, these areas are carefully fitted and inspected until all components operate together without excessive play or binding.
What is most important in mold manufacturing?
The key factors are dimensional accuracy, precision fits, and surface quality. Parting surfaces, guide elements, and functional areas must be manufactured and matched with high precision to ensure smooth mold operation and accurate reproduction of the part geometry.
