Hot Runner System Plastic Injection Mold

 

Basic knowledge of injection molding process
1. Definition of injection molding
Injection molding is a plastic processing method that uses an injection molding machine to inject plastic raw materials into a mold. By controlling parameters such as pressure and temperature, the plastic raw materials are molded into the desired shape of the product.
2. Basic Principles of Injection Molding
The basic principle of injection molding is to use the injection pressure of the injection molding machine to forcibly inject plastic raw materials into the mold, and the plastic melts and fills the mold cavity under high temperature and pressure. During the injection process, plastic raw materials are subjected to shear forces, causing them to flow and fill all corners of the mold. After the plastic cools and solidifies, the product is taken out of the mold.
3. Injection molding process parameters
The process parameters of injection molding mainly include injection volume, injection pressure, injection speed, mold temperature, and plastic temperature. These parameters have a significant impact on the quality and performance of the product. The injection volume determines the size and weight of the product, while the injection pressure and injection speed affect the flow behavior and filling degree of plastic in the mold. The mold temperature and plastic temperature affect the melting state and fluidity of the plastic.
4. Injection molding equipment
Injection molding equipment mainly includes injection molding machines, molds, cooling equipment, conveying equipment, and auxiliary equipment. Injection molding machines are the main equipment, and their performance parameters such as injection pressure, injection speed, and locking force have a significant impact on the quality and production efficiency of products. Mold is a tool for forming products, and its design and manufacturing accuracy have a significant impact on the performance and appearance of the product. Cooling equipment is used to control the temperature and cooling rate of plastic, conveying equipment is used to transport plastic raw materials into the injection molding machine, and auxiliary equipment includes robotic arms, extraction devices, etc.
5. Injection molding materials
Injection molding materials mainly include thermoplastic, thermosetting plastics, and elastomers. Thermoplastics such as polyethylene, polypropylene, polyvinyl chloride, etc. have the advantage of being reprocessed and are widely used in daily necessities, packaging materials, and other fields. Thermosetting plastics, such as epoxy resin and phenolic resin, have high strength, high heat resistance, and good electrical properties, and are widely used in fields such as electronics and automotive components. Elastomers have flexibility and elasticity, and are widely used in fields such as rubber products.
6. Injection molding defects and solutions
During the injection molding process, various defects may occur, such as burrs, shrinkage marks, bubbles, warping, etc. Flash is a phenomenon of plastic overflow, mainly caused by excessive injection pressure or improper mold design. Shrinkage marks are dimensional changes caused by plastic shrinkage, mainly due to insufficient injection pressure or high plastic temperature. Bubbles are caused by the presence of gas in plastic, mainly due to the high temperature or rapid injection speed of the plastic. Warpage is a deformation caused by uneven internal stress in plastic, mainly due to uneven injection pressure and temperature. To address these defects, methods such as adjusting process parameters, optimizing mold design, and controlling plastic raw materials can be used to solve them.
