Plastic molded parts are various parts or products manufactured through the plastic molding process. These molded parts are widely used in many industries such as automotive, electronics, home appliances, packaging, medical and others, and are favored for their light weight, low cost, corrosion resistance, and ease of processing and molding. Plastic molding processes include injection molding, blow molding, extrusion molding, compression molding and other methods, each of which is suitable for plastic molded parts of different shapes, sizes and performance requirements.
1. Technical principle of plastic molded parts
The technical principle of plastic molded parts lies in the use of plastic at high temperatures, softening, flow characteristics, through the mold constraints, so that the plastic in the mold cavity filling, cooling, curing, so as to obtain the required shape and size of the molded parts. Different molding processes differ in heating methods, plastic flow methods, mold structure, etc., but the basic principles are similar. Injection molding is one of the most common plastic molding methods, it is injected into the mold cavity through high-pressure molten plastic, to be cooled and cured after demolding to get molded parts.
2.Plastic molded parts product customization
Plastic molded parts support highly customized services to meet the specific needs of different industries and customers. The process of product customization usually includes the following steps:
Demand analysis: In-depth communication with customers to clarify the shape, size and performance requirements of the product.
Mold design: According to customer demand for mold design, to ensure that the mold structure is reasonable, easy to process, low cost.
Mold Manufacturing: Adopt advanced processing equipment and technology to manufacture molds to ensure mold precision and durability.
Molding production: Heat the plastic raw material to molten state, and manufacture the molded parts through the molding process.
Quality Inspection: Strict quality inspection is carried out on the molded parts to ensure that the products meet the requirements of customers.
3.Introduction of plastic molding materials
There are many kinds of materials commonly used for plastic molding parts, and each material has unique characteristics and application scope. The following is a list of some common plastic materials and their ●.
Polypropylene (PP): good chemical resistance, moderate heat resistance, low cost, suitable for the manufacture of daily necessities, packaging materials.
It is lightweight, easy to process, and impact resistant.
Non-toxic, odorless, environmentally friendly and recyclable.
●Good heat resistance, can withstand a certain high temperature environment.
