Mold processing refers to the processing of forming and ingot making tools, including shearing dies and punching dies. Generally, molds consist of upper and lower parts. Placing steel plates between the upper and lower molds, materials are formed under the action of a press. Upon opening the press, the workpiece determined by the shape of the mold is obtained or corresponding waste is removed.
Mold processing is the processing of forming and ingot making tools, including shearing dies and punching dies. Normally, molds consist of upper and lower parts. By placing steel plates between the upper and lower molds, materials are formed under the press. Upon opening the press, the workpiece determined by the mold shape is obtained, ranging from small electronic connectors to large automotive dashboards. Transfer dies automatically move the workpiece from one station to another, creating the final molded part. Mold processing techniques include die cutting, blanking dies, compound dies, extrusion dies, four-slide dies, transfer dies, punching dies, and punching dies among others.
Types of molds include:
1. Metal stamping molds: continuous molds, single stamping molds, compound molds, stretching molds
2. Plastic molding molds: injection molds, extrusion molds, thermoforming molds
3. Die casting molds
4. Forging molds
5. Powder metallurgy molds
6. Rubber molds
The mold processing process involves steps such as rough cutting, framing, roughing, coppering, wire cutting, CNC machining, EDM, drilling, pinholes, ejector pins, water channel holes, row pressing, tilt punches, complex ejector pins, matching ejector pins, and more.
Other aspects include gating, mold modules, limit pins, ejectors, sprue, support heads, springs, cooling, mold saving, polishing, front and rear mold backbone locations, fine water structures, pull rod screws, springs, heat treatment of critical components, quenching, surface nitriding, and more.
