Shell plastic injection molds are special tools used to produce a variety of plastic shells, which are widely used in electronics, home appliances, automobiles, medical devices, toys, communication equipment and many other industries. These molds are made by injecting plastic heated to a molten state into the mold cavity, and after it cools and solidifies, a plastic shell of the desired shape is formed.

What are the considerations for Shell Injection Molded Products design?

The design of plastic injection molds for enclosures needs to take into account the flow characteristics of the plastic material, shrinkage, the cooling system of the mold, and the demolding design of the product. The mold usually consists of a moving mold (moving part) and a fixed mold (fixed part), which are precisely designed to ensure the dimensional accuracy and surface quality of the plastic shell.

What materials are generally chosen for housing Plastic Parts molds?

Mold materials are usually selected from high hardness and wear-resistant steels, such as pre-hardened steel, high-speed steel or stainless steel, to ensure mold life and machining accuracy. For special needs, such as housings with high gloss surfaces, the mold surface may need to be chrome plated or polished. 

What is the machining and manufacturing process of plastic injection molds for housings?

Manufacturing Custom Injection Molded Products usually involves a variety of precision machining technologies such as CNC milling (CNC), electric discharge machining (EDM), wire cutting, grinding and so on. The complexity and precision requirements of the mold determine the difficulty and cost of the machining process.

The injection molding process consists of the steps of heating the plastic, injecting, holding pressure, cooling and demolding. The precise control of injection pressure, temperature and time ensures uniform filling and good performance of the plastic shell.
