plastic blowing machine factory

The solenoid valve is damaged 4. Adjust baking Box temperature product wall thickness unevenness 1, parison wall thickness unevenness 2, parison temperature unevenness 3, too low stretch off ratio 4, stretch rod offset 1, adjust preform parison 2, adjust oven temperature distribution 3. Polished mold surface products appear pearly white Partial gate position deviation 1. Advance the blowing time slightly 3. Inappropriate drawing temperature 1. Increase the stretching ratio 4.

Adjust the oven heating temperature to reduce the temperature of the bottleneck part and plastic blowing machine factory increase the temperature at the bottom part. Check the circuit 2. Increase air flow 3. Improper selection of blowing time 3. Blowing time is ahead of time 3. The pre-molded parison is not transparent 2. Increase the secondary heating temperature and extend two Secondary heating time 2, slow down the blowing time 3, change the temperature distribution of the oven 4, increase the linear speed of the product cannot be formed 1, the blowing pressure is insufficient 2, the blowing air flow is insufficient 3, the blowing pressure rise rate is too slow 4 1. Reduce the drawing and blowing temperature 2.

The sleeve is worn 1. Increase air pressure 2. Adjust the middle thickness of the stretched rod product 1. Preform parison blowing temperature is too low 2. The heating time is too long 4. Preform parison temperature is uneven 4. Increase the pull-blow speed 2. Moisture in the blowing air 5. Increase the voltage 2. The secondary heating temperature is too high 3. Check the gas path 3. The time relay does not work 1. Increase the temperature at the top of the oven and lower the temperature at the bottom. Rough surface of the blow mold 1. Incorrect secondary heating speed 1. The time relay is damaged 1.

The clamping guide is worn 6. Stretching linear speed is too low 1.No action for failure and phenomenon reasons 1. Excessive tensile force 5. The bottom of the product is thick and thick 1. Delay the blowing time 3. Lower the heating temperature in the middle of the oven 1. The blowing speed is too low 2. Reduce the blowing temperature 2.
