Is it better to stick the Automotive Wiring Harness Protection Sleeve cold or hot?

How is the Automotive Wiring Harness Protection Sleeve bonded into a circle? Some of the silicone rings sold on the market look ugly and have poor stretching strength, while some are very beautiful and will not deform after long-term use, no matter how much they are torn. Cracked, why is the same Automotive Wiring Harness Protection Sleeve but the difference is so big.

In fact, this is mainly related to the bonding glue and production process. Generally, after extrusion molding, the Automotive Wiring Harness Protection Sleeve is bonded according to the customer's specified requirements. Silicone product manufacturers know that the bonding process includes hot bonding and cold bonding. Distinguish, although it is simple bonding, but it can be done carelessly.
"Cold sticking" requires the operator to formulate the glue according to a certain ratio, then squeeze out some glue onto a clean white cloth, and then stick a little glue on one of the two ends of the car harness protective cover that has been cut (note the glue Not too much to prevent overflow on the surface of the product, nor too little to prevent the product from sticking firmly), after the glue is glued, put it directly on the fixture, align and push the two ends so that the two ends are bonded firmly.
The use of cold bonding technology requires the operator to grasp it properly. When bonding, neither press the product too hard nor remove it too lightly, because if the glue is too hard, the glue will stick to the fixture, and if it is too light, it will easily cause the product to not stick firmly or the product Gaps appear. The cost of cold bonding is relatively low. Most silicone products will choose cold bonding when the requirements are not high. The disadvantage of cold bonding: because the whole process is manual operation, some glued products will absorb too much glue and affect the beauty of the product itself. There isn't enough pull either.
Hot-bonding: Glue preparation is the same as cold-bonding, but the formula is different. The operator puts the glue on the product and puts it on a special hot-bonding machine, and uses manual pedal control to make the two ends stick firmly, without manual manipulation. Strength, but also need to control the amount of glue. Using thermal bonding, the production capacity of the product can be increased, and the products that are glued out are also more beautiful. However, the glue cost of the "hot stick" formula is relatively high, and it needs to be refrigerated.
