The main reason for the under-injection is that the flow resistance is too large, which prevents the melt from continuing to flow. Factors affecting the melt flow length include: part wall thickness, mold temperature, injection pressure, melt temperature and material composition. These factors can cause short bets if not handled properly. Therefore, how to eliminate the under-injection defects of metal powder injection molding is very important. The following is a brief introduction by Shenzhen Best Editor to eliminate the under-injection defects of metal powder injection molding: 1. Improper control of process conditions: it should be adjusted appropriately. 2. The injection capacity of the metal powder injection molding machine is less than the weight of the plastic parts: a larger size metal powder injection molding machine should be used. 3. The cross section of runner and gate is too small: it should be enlarged appropriately. 4. The flow distance of the melt in the mold cavity is too long or there is a thin-walled part: cold cavity should be set. 5. Poor exhaust of the mold, the residual air in the mold cavity leads to under-injection: the exhaust system of the mold should be improved. 6. The flowability of raw materials is too poor: resin with better flowability should be used. 7. The temperature of the barrel is too low, the injection pressure of the metal powder is insufficient or the injection time of the replenishment is too short. The above is the troubleshooting method for under-injection defects of metal powder injection molding organized by Shenzhen Best Editor.
