What is the impact of manufacturing process on plastic injection mold

The manufacturing process of plastic injection molds directly affects the quality, performance and production efficiency of the mold. Reasonable selection and optimization of manufacturing processes can improve the accuracy, wear resistance and service life of molds, thus promoting the development of plastic product production.

CNC machining technology

CNC machining technology plays a vital role in plastic injection mold manufacturing. Precise processing of the mold through CNC machine tools can ensure that the geometric dimensions and surface quality of the mold meet the design requirements. CNC machining technology has the advantages of high efficiency, high precision, and good repeatability, and can improve the processing efficiency and quality stability of molds.

EDM technology

Electric discharge machining technology is a commonly used mold processing method, especially suitable for processing hard materials and complex-shaped mold parts. Through electric pulse discharge, tiny discharge holes are formed on the surface of the workpiece, and the material is gradually removed, thereby achieving high-precision processing of the mold. Electrical discharge machining technology can process cemented carbide with a hardness of over HRC60, improving the wear resistance and service life of the mold.

3D printing technology

In recent years, with the continuous development of 3D printing technology, its application in plastic injection mold manufacturing has gradually increased. 3D printing technology can quickly manufacture complex-shaped mold parts, shorten the development cycle, and reduce manufacturing costs. At the same time, 3D printing can also realize customized production to meet the personalized needs of different customers. However, due to the limitations of the characteristics of 3D printing materials, there are still certain challenges in manufacturing molds with high precision and high wear resistance requirements.

Heat treatment technology

Heat treatment technology plays an important role in plastic injection mold manufacturing. Through heat treatment, the hardness, strength and wear resistance of the mold can be improved, and its service life can be extended. Common heat treatment processes include quenching, tempering, carburizing, etc., which are selected according to the different mold materials and usage conditions to achieve the best heat treatment effect.

Surface treatment technology

Surface treatment technology is crucial to improve the surface quality, corrosion resistance and wear resistance of the mold. Common surface treatment methods include mirror polishing, sandblasting, electroplating and spraying. Through reasonable surface treatment, the appearance quality of the mold can be improved, friction loss can be reduced, and the service life of the mold can be extended.
