method for producing bubbles in plastic buckets

In the production process of plastic bucket bubble phenomenon, the quality of the barrel will seriously decline, output value to plastic bucket manufacturers have brought serious economic losses, so plastic bucket foam how to do?

1, improve the exhaust state of plastic bucket mold.

2, increase the plastic temperature, make the activity smooth. Reducing the temperature of the plastic can reduce the shrinkage rate, and increasing the temperature of the injection mold appropriately, especially simply increasing the local forming temperature of the part that constitutes the vacuum bubble, can reduce the probability of bubble occurrence.

3, improve the plastic injection energy, injection pressure, speed, time, material quantity should be improved, at the same time to develop back pressure, further enrich the plastic filling.

4, plastic into a warm environment, its water will condense in the cold plastic, the use of dry plastic can compensate for this situation.

5. The plastic activity of the plastic bucket mold is not uniform, and the air is trapped inside. This problem can be dealt with by using a vacuum to discharge the mold.

Generally speaking, the foam that plastic bucket or light color produces can be observed directly, but the foam that brunet bucket wall produces sometimes cannot see easily through the surface, want to dig bucket wall ability to discover in the experiment. If the products cannot be sent to customers in time, quality accidents will occur, causing immeasurable losses to the later cooperation between enterprises and customers.
