How is the plastic mold manufacturing process？

Plastic mold manufacturing process is a complex and fine process, usually including mold design, material selection, CNC machining, precision machining, assembly and debugging 8 steps.

The following will detail the various steps of the plastic mold manufacturing process:

(1) Demand analysis and design: according to customer needs and product requirements, demand analysis and design. This step includes the determination of the size, shape, material and other parameters of the product, and the design of the mold structure and the decomposition of the parts.

(2) Material selection and procurement: according to the design requirements, choose the appropriate mold material. Common mold materials include steel, aluminum alloy and so on. Then, the materials are purchased and prepared.

(3) CNC machining: The use of computer numerical control (CNC) machine tools to process mold materials. This step includes operations such as turning, milling, drilling, etc., in order to process the mold material into the desired shape and size.

(4) Precision machining: on the basis of CNC machining, more fine processing technology, such as electric discharge machining, wire cutting, etc. These processes can realize high-precision machining of the mold and ensure the quality and accuracy of the mold.

(5) Surface treatment: Surface treatment of the mold to improve its wear resistance and corrosion resistance. Common surface treatment methods include heat treatment, electroplating, spraying and so on.

(6) Assembly and debugging: Assemble the machined mold parts and debug them. This step includes the assembly, adjustment and testing of the mold to ensure the normal operation and stability of the mold.

(7) Test and repair mold: after the completion of the assembly and debugging of the mold, the test mold and repair mold. Through the injection molding machine to test the mold, check the mold molding effect and product quality. If a problem is found, it is necessary to repair the mold and adjust the structure or size of the mold to achieve the desired molding effect.

(8) Production and maintenance: After the completion of trial and repair, the mold can be put into formal production. In the production process, the mold needs to be regularly maintained and maintained, including cleaning, lubrication, replacement of wearing parts, etc., in order to extend the service life of the mold and ensure the production quality.

To sum up, the plastic mold manufacturing process includes demand analysis and design, material selection and procurement, CNC machining, precision machining, surface treatment, assembly and commissioning, mold trial and repair, production and maintenance and other steps. Each step requires fine operation and strict quality control to ensure that the quality and performance of the mold meet the requirements.
