The Solution of Mold Flash
What‘s the causes of mold flashes？There are four main reasons.
1. The parting line surface does not match slide surface;
2. Injection pressure is too high;
3. Offset of injection machine;
4. Insufficient clamping force.
The parting line surface ,slide mating surface，demoulding pin, spacer and other parts of mold constitute mold’s gaps between grooves. The loss of material becomes flash. The flash is wedge block and a tendency to grow larger. To eliminate the flash of the product follows the principle to repair the mold. The temperature of the cylinder should be lowered if the flash appears temporarily due to the bad setting of forming conditions, reduce mold temperature.
What’s the solution of Mold Flash？
1. Emergency method: Reduce the injection pressure, reduce the temperature of the heating cylinder and reduce the injection speed;
2.Short-term method: grind the mold surface with flash ;
3.Long-term method: Using professional machine-Die inspection machine
