CNC Machining Services by ChainHub – Milling and Turning for Precision Parts

CNC Machining Services by ChainHub

At ChainHub, we specialize in CNC machining services that deliver high-precision components for mold manufacturing. With advanced CNC milling and CNC turning capabilities, we produces essential mold-related parts that ensure durability, accuracy, and long service life.

Whether you need one replacement component or a complete mold set, ChainHub offers machining solutions tailored to your production needs.

Our CNC Machining Capabilities

CNC Milling – Ideal for machining cavities, cores, inserts, and components requiring complex 3D geometries and precision finishing.

CNC Turning – Best suited for cylindrical components such as neck rings, cup cores, and blow pins, where roundness and tight tolerances are critical.

Key Mold Components We Manufacture

1. Die Heads 

CNC-machined die heads ensure smooth material flow, uniform wall thickness, and consistent parison formation in extrusion blow molding.

2. Cup Cores

Using CNC turning and polishing, we produce cup cores with precise dimensions and high surface quality, forming the inner structure of molded parts.

3. Mold Inserts 

CNC milling allows us to create durable and interchangeable mold inserts. Inserts can be easily replaced or customized to add features such as engraved logos, product identification marks, or grooves, giving manufacturers greater adaptability without needing to rebuild the entire mold.

4. Neck Rings

Machined with CNC turning for precision, neck rings define bottle threads and sealing areas. Perfect accuracy ensures leak-proof closures and cap fit.

5. Cores & Cavities

With CNC milling and EDM, ChainHub produces high-quality cores and cavities that directly shape the final product, ensuring smooth parting lines and excellent finish.

6. Blow Pins 

CNC turning produces robust blow pins with perfect air channels, guaranteeing uniform inflation during blow molding.

7. Cooling Plates & Components

Through precision CNC milling, we manufacture cooling plates and channels that optimize heat dissipation, reducing cycle times and improving consistency.
