Causes of product defects in injection molding
Injection molding processing is a kind of plastic processing technology, in our life to carry forward great benefits, but through Changzhou injection molding processing of the finished product will also have shortcomings, speaking of this, the following to friends to explain the reason for this situation.
In the real manufacturing work, not all finished products can pass, there are definitely defective finished products, after all, what is the reason for the shortcomings in the injection molding process, the beginning is the reason that the finished product cannot be replenished. There are many reasons for the inability to replenish: 1. The exhaust of the mold cavity is not smooth, the pouring system is blocked, the injection time is short, and the fluidity of raw materials is too poor, resulting in insufficient supplementation; 2. The temperature of the barrel, nozzle and processing machinery is too low. 3. The runner or gate is too small and the quantity is not enough, and the position is improvoked. The second is the overflow of the finished product, which is caused by excessive filler and too much fluidity of raw materials. Later, there are bubbles in the finished product, which is caused by poor drying of the plastic, so it is necessary to search and inspect in advance during processing.
Injection molding parts processing is widely used in our lives, and the double injection molding process is a kind of injection molding parts processing technology. The double injection molding process refers to the injection molding of two different plastic materials through technical means, which has the following three outstanding advantages: First, the change of touch feeling. In the past, the feel of some injection molding products could not reach the consumer's hand experience, and the double injection molding process can simply promote the touch feel, and the product it creates is more like a carefully crafted handicraft. Second, double the easy to use. The product life of the product manufactured by the double injection molding process can not only be greatly improved, but also the strength and wear resistance of the product will be greatly improved. Third, the visual blow. The pleasing or not of the surface simply influences our desire to buy, and the double injection molding process can double the specificity of the surface color of the product. The volume of sales of products will be greatly increased.
It is explained that the shortcomings of the finished product in injection molding processing are explained here, and it is expected that friends can pay attention to the above points in the process of injection molding, and if there are shortcomings, it will be reduced. However, the staff should also pay attention to itself when performing injection molding.
