Defects analysis of injection molded products - Bubbles Jan 17, 2020
Bubbles are the phenomenon of small volume or series of pores formed inside the product. A large amount of gas is mixed into the melt and is formed by cooling the melt. 1. Venting system is bad or blocked 2. The cooling system is not setting properly, which makes the material cooling uneven or insufficient. 3. The injection speed is too fast 4. The material temperature is too high, which will caus...

Two-color mold design and injection tips Mar 20, 2020
1. The water circiuts of the cavities and cores is designed as full as possible and balanced. 2. After the cavity rotates 180 ° from the center, it must match the core. 3. Usually, injecting the hard rubber part first, and then the soft rubber part, because soft rubber is easy to deform. 4. The nozzle of the three-plate mold should preferably be designed to automatically demolding. Special attenti...

Tips for injection molding of nylon cable ties Apr 10, 2020
1. Pay attention to mold temperature If the lower temperature of the heat-resistant and abrasion-resistant nylon cable ties in the production, the faster the material cooling rate in the mold cavity, so that it can greatly shorten the take-out time of the product and improve the efficiency of the molding operation. However, if the temperature is too low, it will easily cause the appearance of the ...
