Door service hole cover Thailand
We will develop and manufacture the optimum door cover according to the customer's needs.Kawashima Co., Ltd. manufactures door waterproof film covers (service hole covers/door seals/door holes) that prevent rainwater from entering the vehicle through the door window.
Low cost is realized by using Kawashima's original welding processing technology without using adhesive for processing. In addition, we can flexibly process according to customer needs, such as manufacturing covers that are not only waterproof but also soundproof (sound absorbing).
To make the service hole cover more difficult to peel off.
Task
Cushioning and soundproofing materials such as urethane and felt are attached to the service hole cover with adhesive.
However, there was a problem that the adhesive strength weakened depending on the temperature at the time of pasting and the pressure applied when pasting, and it peeled off over time.
Resolution
By performing corona discharge treatment on the film surface,
Succeeded in strengthening the adhesion with the mating object.
In particular, since the attachment to the vehicle is done manually one by one,
Although there was some variation in the amount of adhesive applied and the pressure applied, we were able to solve the problem of peeling due to corona discharge treatment.
