Tooling and Mold Machining Expert in CNC Machining

Precision Requirements in the Tooling and Mold Industry

The global manufacturing landscape relies heavily on high-performance tooling and precision molds to enable mass production with consistency, efficiency, and tight tolerances. Whether for injection molding, die casting, stamping, or extrusion, the quality of the mold or die directly influences the reliability, surface finish, and dimensional accuracy of the final product.

To meet the growing complexity of product designs and shorter lead times, mold and tool manufacturers require a trusted tooling and mold machining expert with advanced CNC machining capabilities. This combination of precision engineering and digital manufacturing ensures high-accuracy components that deliver exceptional mold life and production consistency.

Manufacturing Challenges and Technical Solutions

Tooling and mold components are some of the most demanding parts to produce due to:

• Complex 3D geometries, including deep cavities, undercuts, and conformal cooling channels;
• Extremely tight dimensional tolerances for mating surfaces and inserts;
• High hardness materials, often heat-treated before or after machining;
• Surface finish requirements for mirror-like polishing in optical-grade molds;
• Thermal stability and wear resistance to withstand continuous production under heat and pressure.

We address these challenges through:

• 5-axis high-speed CNC milling for intricate mold core and cavity geometries;
• EDM (Electrical Discharge Machining) for sharp internal features, deep ribs, and hardened steel processing;
• CNC grinding for flatness and precision surface control;
• Advanced CAD/CAM programming to ensure optimized tool paths and minimum machining time;
• Polishing, heat treatment, and PVD surface coating for improved mold life and part ejection performance.

Each mold component is processed with strict dimensional control and is customized to your tooling standards, be it DME, HASCO, or proprietary systems.

Commonly Used Materials and Their Properties

Material selection is a critical factor in mold and die manufacturing. We offer machining for a wide range of tool steels and engineering alloys, tailored to specific tooling needs:

• P20 (1.2311 / 1.2312 Tool Steel): Pre-hardened mold steel with good polishability and machinability; ideal for plastic injection molds.
• H13 / SKD61: Hot work tool steel used for die casting and high-temperature molds due to its excellent toughness and thermal fatigue resistance.
• S136 / 420 Stainless Steel: Corrosion-resistant mold steel suitable for medical and food-grade molds.
• 1.2738 / 718H: Pre-hardened alloy with high core hardness and excellent weldability.
• Graphite & Copper Electrodes: For EDM mold manufacturing, offering high wear resistance and fine detail replication.

These materials can be heat-treated to required hardness (up to HRC 52–58), and are selected based on the molding material, production volume, and surface finish needs.

Project Example: High-Cavitation Mold Insert for Medical Parts

For a client in the medical sector, we recently delivered a 16-cavity mold insert set with ultra-tight tolerances:

• Material: S136 stainless steel, hardened to HRC 48
• Cavity Tolerance: ±0.005 mm
• Surface Finish: Ra ≤ 0.1 μm, mirror polished
• Features: Micro channel venting, ejector pin holes, gate land with EDM precision
• Delivery Time: 12 business days from design approval

The tool passed the first-shot qualification and was installed in a 24/7 cleanroom production line.
