1.Introduction of customized plastic injection molded parts service
Custom plastic injection molded parts service, in short, according to the specific needs of customers, through the injection molding process, the molten plastic material into the mold, cooling and curing to get the desired shape of the part. This service is highly flexible and customized, and can meet the diversified needs of different industries and products.
2.Injection molding process
Design and planning: First of all, customers need to define the shape, size, material and characteristics of the required parts. Designers use CAD software for three-dimensional modeling to ensure the accuracy and feasibility of the design.
Mould Manufacturing: According to the design drawings, the professional team will manufacture the injection molds. The precision and quality of the mold directly affect the quality of the final product.
Raw Material Preparation: Suitable plastic raw materials such as PEEK, PPS, PPSU and other high performance materials are selected to ensure the performance and durability of the parts. Raw materials are loaded into the feeding system of the injection molding machine.
Injection process: The injection molding machine heats the plastic raw material to a molten state and then injects it into the mold through high pressure. The plastic cools and solidifies in the mold to form the desired shape of the part.
De-flashing and Finishing: After injection molding, excess plastic or flash is removed to make the surface of the part smoother and flatter.
Quality Control: Rigorous quality control checks are carried out to ensure that the dimensions, appearance and other key characteristics of the part meet customer requirements.
Assembly and Packaging: If required, multiple parts are assembled together and final packaging is performed for shipment to the customer.
