With the development of technology and market demand, injection molding technology is constantly advancing and improving. Modern injection molding equipment has achieved intelligent and digital control, and production efficiency and product quality have been further improved. In the future, injection molding technology will continue to develop and grow, bringing more opportunities and challenges to the development of the plastic product processing industry.
In industrial production, injection molding is widely used in fields such as electronics, automotive parts, daily necessities, medical devices, and industrial accessories. In the field of electronic appliances, products such as phone cases, keyboards, and mice are all manufactured through injection molding; In terms of automotive components, such as car lights, door handles, instrument panels, etc., injection molding technology is also used for production; In the field of daily necessities, such as plastic cups, chopsticks, hangers, etc., injection molding is also a common application. It can be said that injection molding technology has become an indispensable and important process in modern industrial production.
What are the manufacturing accuracy requirements for Dalian injection molded products?
Dimensional accuracy: The dimensional accuracy of injection molded products refers to the deviation between the product and the design dimensions. Generally speaking, the dimensional accuracy requirements of injection molded products are relatively high, especially for precision parts, the deviation range is usually between tens of micrometers to hundreds of micrometers. The control of dimensional accuracy mainly depends on factors such as mold design, injection molding equipment performance, raw material quality, and production process.
Surface smoothness: The surface smoothness of injection molded products refers to the smoothness and absence of defects on the outer surface of the product. Good surface finish can improve the texture and appearance of products, suitable for high-end products and products with strict appearance requirements. The control of surface smoothness usually requires selecting appropriate mold surface treatment methods, setting injection molding process parameters, and post-treatment processes.
Material uniformity: The material uniformity of injection molded products refers to the requirements for the density, fluidity, and performance uniformity of the internal materials of the product. Excellent material uniformity can effectively avoid defects such as bubbles, thermal shrinkage, and shrinkage inside the product, improving its performance and stability. The control of material uniformity mainly includes the setting of injection molding process parameters, optimization of raw material melting, injection and cooling processes, and other aspects.
Injection molding has the following characteristics: firstly, it can produce products with complex shapes and rich details; secondly, it has high production efficiency, accuracy, and low cost; thirdly, it can achieve multi variety and small batch production by changing the mold and process parameters; fourthly, it can achieve automated production, improve production efficiency, and reduce labor costs.
The process flow of injection molding mainly includes raw material pretreatment, injection molding machine operation, mold design, molding process parameter control, and product quality inspection. Firstly, the plastic raw materials are dried, mixed, heated and melted, and then the molten plastic is injected into the mold by an injection molding machine. After a certain pressure and temperature control, the plastic can be cured and formed in the mold. Afterwards, plastic products that meet the design requirements are obtained through processes such as cooling, demolding, and trimming.
