CNC machining in injection mold manufacturing
CNC machining is an important process in injection mold manufacturing, which uses computer-controlled tools to remove material to create a specific shape. It is a versatile process that can be used to machine a wide range of metal or plastic products.
The CNC machining process for injection molds includes the following steps:
1. Design. The injection mold is first designed using computer-aided design software. The CAD model is then converted into a computer-aided manufacturing program, which generates the instructions for the CNC machine.
2. Material selection. The appropriate material for injection mold is selected. The most common material is tool steel, but aluminum or copper can also be used.
3. Preparation. The solid material is prepared for machining.
4. Machining. The CNC machine uses the CAM program to machine the injection mols.
Specific applications of CNC machining in injection mold manufacturing include:
1. Cavity and core machining. CNC machining is the preferred method for manufacturing cavities and cores, as it can provide high accuracy and can be used for complex shapes.
2. Cooling system machining. CNC machining can be used to machine the cooling system of injection molds.
3. Assembly locating device machining. CNC machining can be used to machine assembly locating devices, such as guide pins and locating pins.
CNC machining is an essential tool in injection mold manufacturing, as it can provide the mold with high machining quality and accuracy, while also reducing costs
