The plastic dyeing tube was easily cracked and damaged at low temperature in winter, and the edge of the nozzle is damaged.

Customer's Concern

The dyeing tube with broken edge may have scratch damage during the handling operation.


1.Multiple comparison tests for raw material ratio of plastic pipe to improve the fragility of plastic pipe under low temperature conditions in winter.

2.After several rounds of internal test, the most suitable tube was sent to the customer for dyeing high temperature test.

3.After the customer dyeing test passed, it was formally applied to large-scale production.


Plastic dyeing tube after improvement:

1.Adapted to the low temperature of winter.

2.No more crack.

3.The feedback of customer was good.
