Hot pressing welding mainly uses electric heating to control the temperature change and transfer heat to the plastic parts using a hot melt head to achieve the desired effect of hot pressing deformation. This process is usually used for welding soft plastic parts in automotive interiors. The specific steps include:
1.Put the lower rubber part of the product: put the lower rubber part to be welded into the welding fixture.
2.Lower fixture suction: start the fixture to fix the lower rubber part.
3.Put the upper rubber part of the product: put the upper rubber part to be welded into the fixture and align it with the lower rubber part.
4.Upper fixture suction: start the fixture to fix the upper rubber part.
5.Hot plate enters and heats: start the hot plate welding machine, let the hot plate enter the fixture, and heat the upper and lower rubber parts.
6.Hot stamping: The hot plate continues to heat, so that the upper and lower rubber parts reach a molten state, and hot stamping.
7.Bonding: During the hot stamping process, the upper and lower rubber parts are gradually bonded together.
8.Cooling and taking out the product: After the welding is completed, turn off the hot plate welding machine, and take out the finished interior parts after cooling.
It should be noted that each heat bonding production process has its own characteristics and scope of application. In the actual production process, the appropriate process method should be selected according to the specific requirements and production conditions of the interior parts. At the same time, regular maintenance and maintenance of production equipment is also required to ensure the stability of the production process and product quality.
