-Reduce the impact force onto the mould from the outside or use thermoplastic less susceptible to stress over. -Review the product design to improve flow. -Increase the mold surface temperature and heat flow of the resin, reducing the pressure to maintain, reset the time and injection speed to match. Select the clear structure of the product and make sure retrieve products in a great extent which does not damage the product. -Reduction of injection pressure, reducing compaction pressure. -Reduce mold temperature, check the temperature of the mold evenly.
