Customized Precision Mold Components Mold Parts for Plastic Mulit Cavities Molds Cap Mold

Core Business

We focus on precision machining of multi-cavity mold components, including plastic mold cavities, core pins, inserts, movable core assemblies, and automotive die-casting mold cores and inserts. Our products are primarily used in precision packaging molds for industries such as daily-use packaging, cosmetics packaging, medical consumables and packaging, as well as automotive, electronics, and automation.

Materials--Premium Tool Steel for Precision Mold Parts | Sourced from Global Leaders

While our expertise lies in machining multi-cavity molds for cosmetic caps, medical syringes, and automotive components down to micron-level accuracy, every masterpiece begins with its raw material.We strategically source tool steel exclusively from global leaders like Uddeholm, Hitachi, and Böhler,Let me break it down for you:

For H13 Hot-Work Steel:
We go with Bohler Uddeholm® material, which has exceptional thermal fatigue resistance. This makes it perfect for high-temperature injection molding applications like automotive molds and complex cavity inserts. Every batch comes with full traceability, so you know exactly where it's coming from.

For Stavax® ESR (420 Stainless Tool Steel):
This one’s sourced directly from ASSAB® and comes with mill test reports. It’s great for surgical instrument molds and transparent plastic components because of its superior corrosion resistance and ability to achieve a mirror finish, ideal for medical and optical-grade molds.

For M340 High-Hardness Steel:
We get this premium-grade steel from leading European suppliers. It offers extreme wear resistance and maintains precision even under heavy-load cycles, making it perfect for high-volume production molds, thread cores, and ejector pins.

Why Our Materials Matter:
Our raw materials are purchased directly from BOHLER and ASSAB with original certifications. We provide full traceability at the batch level, ensuring compliance with medical and automotive standards like ISO 13485 and IATF 16949. By using optimized steel grades, we extend mold lifespan by 30-50% compared to generic alternatives.

Manufacturing Process-Advanced Machining Techniques for Micron-Level Accuracy

1. Röders CNC Machining:
We use 5-axis CNC machines that can achieve tolerances as tight as ±0.005mm. This allows us to form complex surfaces in one go, ensuring both precision and efficiency.

2. Makino EDM (Electrical Discharge Machining):
Our EDM machines use precise electrode discharge technology to handle intricate structures like deep slots and narrow gaps. This non-contact method is great for hard materials and complex shapes, providing high accuracy while preserving tool life.

3. Sodick Wire EDM (W/EDM):
For ultra-smooth finishes, we use Sodick wire EDM machines. These machines ensure minimal surface roughness, making them perfect for optical components and high-precision molds.

4. Hardinge CNC Turning:
Our CNC lathes offer reliable precision and performance. They can handle a wide range of turning operations with ease, ensuring consistent quality and high productivity.

5. Grinding and Polishing:
We achieve mirror-like surface finishes (Ra ≤ 0.1μm) through advanced grinding and polishing techniques. This not only enhances the appearance but also reduces demolding resistance for injection-molded parts, improving production efficiency and lowering defect rates.

6. Heat Treatment:
To enhance material properties, we combine vacuum quenching and nitriding. This ensures no oxidation or deformation during processing and increases surface hardness and wear resistance, extending the lifespan of the materials.

Quality Inspection-Rigorous Quality Control for Zero-Defect Deliveries

CMM (Coordinate Measuring Machine):
We use Zeiss CMM for full-dimension scanning to make sure everything matches the CAD drawings down to the last detail.

Optical Projector:
Our optical projector allows for quick and precise measurements of tiny holes and thread accuracy.

Hardness Testing:
We verify the effectiveness of heat treatment using Rockwell and Vickers hardness testers.

Cylindricity Instrument:
Our cylindricity instrument ensures perfect cylindrical shapes, meeting the highest standards.

Below are our main quality inspection items in the whole production process:

Material incoming: 100% inspectionRough Finished:100% inspetion
Heat treatment: random inspection
Face grinding: 100% inspection
Center-less cylindrical grinding: 100% inspection
