Explanation of the production process for hot pressing and coating of automotive dashboard

The Instrument panel, referred to as "IP (Instrument panel)", is an important part of the automotive interior. With the progress of science and technology and the improvement of people's living standards. The passenger puts forward higher requirements for the comfort and aesthetics of the instrument panel, and the feel, leather grain, color and tone of the instrument panel will affect the driving experience of the passenger. The surface coating of the instrument panel greatly improves the texture of the interior space, and compared with the production process of the instrument panel of the slush process, it has greatly improved in terms of efficiency, environmental protection and texture.

The basic structure of the skin covering of the instrument panel is shown in Figure 1:

Instrument panel hot pressing skin coating process steps:

Hot pressing coating process features:

First, the instrument panel hot pressing edge coating process has high production efficiency. Due to the use of dual station design, the loading and unloading time is reduced. General single-shift operators 2-3 people, 8-hour single-shift output can be completed about 160-200 pieces.

The one-time arrival rate of hot pressing edging is about 95%, which reduces the manual processing workload of late edging.

Second, due to the use of robot spray glue, so the glue is uniform, and the weather resistance of the interior decoration has a process guarantee. Moreover, from the perspective of cost, because the robot spray has no overspray and leaky spray defects, the use cost of hot melt adhesive is greatly saved

Third, due to the use of the original patented technology varioterm multi-die temperature technology, the different die temperature control in different areas of the hot pressing protection die is realized. It greatly improves product quality and saves power consumption

Fourth, due to the application of variotherm multi-die temperature technology, it ensures that the skin pattern is more clear and beautiful, and the surface of the instrument panel after forming is smooth and without warping deformation.

Fifth, the mold life is long. Because the hot-pressing coating mold uses a process environment similar to hot-pressing molding, the service life of the hot-pressing coating mold can reach more than 10 times the service life of the slush mold

Sixth, hot pressing skin coating process environmental protection. Due to the use of hot melt adhesive spraying, it ensures the "zero VOC emission" of the spraying process, and the air quality in the car is controlled from the source
