5. Injection mold fixture manufacturing process
5.1 CNC machining (CNC machining)
Description: CNC machining is one of the most commonly used processes in the manufacture of injection mold fixtures. It uses computer numerical control technology, through the pre-programmed program to control the movement of the machine tool, to achieve accurate processing of the mold fixture. CNC machining can process complex surfaces and holes to ensure machining accuracy and surface quality.
Features:
High machining precision, suitable for machining complex shapes and sizes of fixtures.
High degree of automation, high productivity.
Stable machining process and reliable quality.
5.2 Electric Discharge Machining (EDM)
DESCRIPTION: EDM is a method that uses the high temperature generated by electric spark discharge to melt or vaporize the metal material, so as to achieve the machining purpose. In the manufacturing of injection mold fixtures, EDM is commonly used to process detailed parts of the mold, deep holes or narrow slits that are difficult to machine with traditional machinery.
Features:
Wide range of processing materials, almost any conductive material can be processed.
High machining accuracy and good surface quality.
Suitable for processing complex shapes and parts that are difficult to process with conventional machinery.
5.3 Wire Cutting (Wire EDM)
Description: Wire EDM is a method of using fine metal wires (usually molybdenum or copper wires) as tool electrodes to melt or vaporize the metal material through the high temperature generated by high-frequency pulsed power discharges, so as to cut out the desired shape. In injection mold fixture manufacturing, wire cutting is commonly used to process complex contours and shapes.
Features:
High machining precision and good surface quality.
Suitable for processing fixtures of various shapes and sizes, especially for complex contours.
Stable processing, high material utilization.
5.4 Grinding Processing
DESCRIPTION: Grinding processing is a method of processing workpieces using abrasives (such as grinding wheels, abrasive belts, etc.). In injection mold fixture manufacturing, grinding processing is commonly used to process the finish and surface quality of the mold, as well as to remove burrs and flying edges generated during processing.
Features:
High processing precision and good surface quality.
Suitable for processing various hardness materials, including cemented carbide and ceramics.
Smooth machining process and high productivity.
5.5 Heat Treatment
Description:Heat treatment is an indispensable part of injection mold fixture manufacturing. By heating, holding and cooling the fixture material, it can improve the organization and properties of the material, and improve the hardness, wear resistance and corrosion resistance of the fixture.
Features:
Improve the hardness and wear resistance of the material.
Improve the organization and properties of the material.
Improve the service life and stability of the fixture.
