What causes the surface of the Automotive Wiring Harness Protection Sleeve to be rough?

After a period of use, the Automotive Wiring Harness Protection Sleeve will become less smooth and sticky, especially on kitchen utensils or Cable Sleeve phone cases. What is the reason for the rough surface of the Automotive Wiring Harness Protection Sleeve? The rough surface of the Automotive Wiring Harness Protection Sleeve may be caused by raw material problems, or it may be caused by improper maintenance. Is it possible that the surface is not smooth enough caused by the improper production of the Automotive Wiring Harness Protection Sleeve manufacturer? The answer must be "yes".

First of all, the control and use of the curing agent during the mixing of raw materials is unreasonable, and the amount of curing agent added is small and the Automotive Wiring Harness Protection Sleeve is not completely cured, resulting in sticky surface of the product. Secondly, the curing agent and the Cable Sleeve are mixed unevenly during mixing, and the mold appears to be cured on one side and not cured on the other, resulting in deformation of the product after molding and vulcanization due to differences in hardness and softness. Finally, the machine mold is not cleaned cleanly during production, the inside of the mold clamping is not smooth enough, and the remaining residues in the mold cause unevenness in the heavy material of the product, resulting in an uneven surface of the product.
In short, there is a problem of rough surface in the production of Automotive Wiring Harness Protection Sleeve. It is necessary to find out the cause of the occurrence and correct it in time, so as to avoid the output of a large number of defective products, resulting in waste of materials and affecting production efficiency.
