The injection molding process refers to the manufacturing process of converting the product drawings and processing requirements provided by customers into a set of usable molds. Generally speaking, the injection mold processing process includes the following 5 steps: (For reference only)

(1) Evaluation and Design

After accepting the customer's order, the injection mold processing manufacturer will evaluate the product drawings provided by the customer and conduct preliminary design according to the product requirements. At this stage, the processing manufacturer needs to confirm key factors such as required materials, mold cavity structure, cooling method, and fully communicate with the customer.

(2) Selection and procurement of processing materials

According to the design plan, select suitable materials and purchase them. Generally speaking, the commonly used mold materials in the mechanical industry include aluminum alloy, steel, etc. Processing manufacturers should consider material selection based on the requirements of different products, including quality, wear resistance, corrosion resistance, and processing difficulty.

(3) CNC precision machining

After the processed materials are in place, CNC machining is required. This process mainly involves machine tool processing based on design drawings, such as milling, drilling, turning, etc. At this point, high-precision equipment and technical operations are required to ensure that the processed parts are consistent with the design drawings and meet the accuracy requirements.

(4) Spark machining

Spark machining is an indispensable part of the injection molding process. It is mainly used for machining complex spatial surfaces and small aperture parts, such as bosses, guide pillars, positioning blocks, etc. Spark machining is actually the use of the principle of electric discharge cutting to perform micro discharge machining on a high-precision workbench.

(5) Grinding and polishing

Grinding and polishing are the final steps in the processing of injection molds. Before the end of mold manufacturing, the surface needs to be ground and polished to improve the surface quality of the mold. This can ensure the smoothness and appearance of the product surface, while also increasing the durability and service life of the mold.
