The Supplier of Plastic Injection Mold
Manufacturing Custom Plastic Injection Molds
Building custom plastic injection molds involves two primary machining methods: Electrical Discharge Machining (EDM) and Computer Numerical Control (CNC) machining. Each method is essential for creating precise mold components that meet complex design specifications.
EDM Machining
EDM uses a copper or graphite electrode to burn the mold shape into the component. This process is ideal for intricate details like sharp corners or thin ribs that cannot be easily cut with CNC. While slower and more expensive, EDM provides unmatched precision for complex mold features. The steps include:
- CNC machining electrodes from copper or graphite.
- Submerging both the electrode and mold in dielectric fluid.
- Using an EDM machine to discharge electricity at a controlled rate to erode the mold material into the required shape.
CNC Machining
CNC machining utilizes computer-controlled technology to cut precise geometries from raw metal blocks. Designers create 3D CAD models that define the mold’s dimensions, which are then converted into CAM software instructions. The CNC machine follows these instructions to cut the mold with high speed and efficiency. CNC machining is faster and more cost-effective for producing large, less intricate features of the mold.
The combination of EDM for detailed features and CNC for broader shapes ensures high-quality, durable molds capable of producing complex plastic parts.

TECHNICAL FAQs
FAQs About Plastic Injection Moulds
A plastic injection mold is a precision tool used in injection molding machines to produce high-volume plastic parts by injecting molten material into a shaped cavity, which then cools and solidifies into the final product.
Plastic injection molds are manufactured using advanced CNC machining and EDM processes. CNC is used for shaping large and precise components, while EDM is used for complex geometries and fine details that cannot be machined conventionally.
CNC machining uses computer-controlled cutting tools to remove material quickly and accurately, while EDM (Electrical Discharge Machining) uses electrical sparks to erode metal for intricate shapes and fine details. Both processes are combined to achieve high-precision molds.
Plastic injection molds are widely used in automotive, medical, electronics, industrial equipment, packaging, consumer goods, telecommunications, and aerospace industries for producing precise and durable plastic components.
Common injection mold steels include P20 for general use, H13 for high-temperature applications, S136 for corrosion resistance, D2 for wear resistance, and NAK80 for high-polish surface finishes. Material selection depends on production volume and application requirements.
The lifespan of a plastic injection mold depends on material and usage. High-quality steel molds can last from hundreds of thousands to over one million cycles with proper maintenance and correct operating conditions.
Plastic injection molding offers high precision, low unit cost for mass production, fast cycle times, design flexibility, minimal waste, and the ability to produce complex geometries with consistent quality.
