Metal Injection Molding Bicycle And Car Tire Special Anti-skid Spikes

The defect control problem during injection molding can basically be divided into two aspects. On the one hand, it is the setting of the functional relationship between the molding temperature, pressure, and time; on the other hand, it is the flow of the feed in the mold cavity during filling. Because most PIM products are small-sized parts with complex shapes and high precision requirements, the flow of the feed in the mold cavity involves mold design issues, including the position of the feed port, the length of the flow channel, the setting of the vent hole, etc. These require a clear understanding of the rheological properties of the feed, the temperature in the mold cavity, and the residual stress distribution. Computer simulation technology will play an important role in the design of powder injection molding molds.

At the same time, product and mold design is one of the key issues in injection molding. Although the weight of products produced now can range from 0.003g to 17kg, and important progress has been made in improving precision, most designs, especially mold designs, are based on experience and lack reliable design knowledge. CAD systems are difficult to apply well to PIM. The principle of plastic molds has been gradually standardized for MIM molds. With the accumulation of experience, the time for mold design and production will be greatly reduced, and more multi-cavity molds will be used to improve injection efficiency. MIM does not require the use of special injection machines now. Ordinary injection molding machines can be slightly improved. Injection molding of many products has been automated, but injection molding of ultra-small parts is still a problem. Qinhuangdao Zhongwei Precision Machinery Co., Ltd. was established in 1997.
