What are the more widely used special processing methods in mold manufacturing? As follows:
Widely used special machining methods in mold manufacturing are as follows:
Electro-discharge machining (EDM): This method utilizes the principle of EDM corrosion to remove material by means of a pulsed discharge between the tool electrode and the workpiece electrode. It is mainly used for machining hard-to-machine materials such as carbide and hardened steel, as well as parts with complex shapes, such as precision molds and gauges.
Electrolytic machining (ECM): this method utilizes an electrolytic reaction to remove material. In mold manufacturing, it is mainly used to process parts with complex shapes such as holes, cavities and surfaces, as well as hard-to-machine materials such as cemented carbide and high-temperature alloys.
Ultrasonic Machining: This method utilizes ultrasonic vibration to remove material. It is mainly used for machining brittle materials such as glass and ceramics, as well as small, thin-walled and complex-shaped parts.
Laser Machining: This method utilizes a high energy density laser beam to remove material. It is mainly used to process a variety of metal materials, as well as small, thin-walled, complex-shaped parts, such as tiny parts, electronic components.
Water Jet Machining: This method utilizes a high-pressure water stream to remove material. It is mainly used for processing a variety of metallic and non-metallic materials, as well as small, thin-walled, complex shaped parts, such as glass, ceramics and so on.
Plasma Machining: This method utilizes a high-temperature, high-speed plasma jet to remove material. It is mainly used to process a variety of metal materials, as well as small, thin-walled, complex-shaped parts, such as aerospace parts, medical equipment.
These special processing methods have their own advantages and applications in mold manufacturing, and the selection of the appropriate method depends on factors such as the material, shape, size and processing requirements of the part.
