In recent years, with the improvement of liquid silica mold technology and the growth of market demand, liquid silica injection molding technology has become more and more extensive. In actual production, for silica gel products manufacturers, we are particularly concerned about how to avoid some common defects in the molding to improve yield and production capacity. Let's discuss the causes and solutions of the formation of pockmarks, a common defect in the production of silica gel products by liquid silica gel injection molding machine.
The liquid silica gel injection molding machine produces silica gel products with pockmarks, i.e. scorching, which seriously affects the appearance, so the products are naturally unqualified. So why are the dots?
The main reason is the following situation in the production process of liquid silica gel injection molding machine:
1. Over temperature
2. Too slow glue injection speed
3. Viscosity of rubber is too high
4. Too fast vulcanization
The production of silica gel products by liquid silica gel injection molding machine can reduce the occurrence of pockmarks of liquid silica gel products and improve product quality through corresponding process adjustment:
1. Adjust the mold temperature properly, reduce the mold temperature for testing.
2. Increase the injection speed.
3. To reduce the viscosity of the material, you can contact the material supplier for adjustment.
4. Slow down the curing rate.
