Why are injection mold components manufactured by CNC machining services?
CNC machining is the only way to achieve the tight dimensions and tolerances required to manufacture high quality injection molding components like the photoelectric mold parts shown above. These parts require precision cylindrical grinding, and machining using the full range of CNC machining services.
To achieve consistent, reliable results in the injection molding process, all injection molding components must be machined extremely precisely. It is not practical to achieve the accuracy required for today’s complex designs without using modern CNC machines.
What components are needed to make an injection mold?
Injection molding has become a very sophisticated technology since it was invented in the 19th Century, with significant breakthroughs in plastic materials in the 1940s and the invention of hollow molding in the 1970s. Today’s molds have multiple components and parts that must fit together perfectly and be machined accurately to compensate for the pressure and thermal expansion of the molding process.
- Mold cavity
- Mold cores
- Mold plates
- Ejector pins
- Gate & runner systems
- Mold inserts
- Molding tools
- Sensors & controls
Injection molds are assembled from many parts, starting with the CNC machining of the mold cavity and mold cores. The mold is held together by mold plates that keep all components aligned, and ejector pins assist in releasing the mold after each injection molding cycle.
The mold cavity creates the shape of the completed part, while mold cores are machined and positioned in the mold cavity to make spaces within the product, including threaded holes for assembly. Inserts can be machined to become part of the finished product. Sensors and flow control components optimize the molding and release processes.
How are CNC machining services used for injection mold component manufacturing?
Component manufacturing for injection molding uses the same wide range of CNC machining services used for mold cavity and core machining processes, including CNC milling, wire and sink EDM and surface grinding to cut intricate shapes and create specific surface finishes.
