Common problems and solutions of Automotive Wiring Harness Protection Sleeve

There are many ways to produce and process Automotive Wiring Harness Protection Sleeve. The processing methods are different, and the produced Automotive Wiring Harness Protection Sleeve are also different, and the quality problems and solutions encountered are also different. Let's follow along with the editor to see what are the common quality problems and solutions for molded Automotive Wiring Harness Protection Sleeve.

1. Common quality problems of Braided Sleeve

①The surface of the product is cracked and peeled, which generally occurs at the joints of the mold.

②with dark brown spots.

③There are white spots on the surface of the product.

2. Reasons for quality problems

①During vulcanization, the Cable Sleeve undergoes strong thermal expansion, shrinkage and compression.

②There are air bubbles and impurities in the Cable Sleeve.

③The fluidity of the Cable Sleeve is not good.

3. Solutions

①Reduce the vulcanization temperature; accurately weigh the Cable Sleeve to reduce the vulcanization pressure; after vulcanization, it will be demoulded when it is cooled to 40-50°C.

②Control the degree of re-smelting to avoid excessive re-smelting; completely compress the mold when pressurizing; set vent holes on the mold to remove the air inside.

③Properly increase the vulcanization temperature.
