Heat stacking is one of the plastic welding methods which weld the work piece by a well designed heating horn, heat the joint position to be designed shape and joint the two parts stably. It is widely used in auto plastic parts welding field, such as auto doors, bumpers, door trims, front grilles, seat backs, logos, etc. It has lots of advantages compared with other welding methods.
Its manufacture cost is lower than the ultrasonic welding. The entire welding time is shorter than the ultrasonic welding machine, about 30~50 second per piece by one cycle. It is also easy to adjust, once the parameter is set, the machine will work stably. Easy to maintain, low power consumption, easy to update. The weld spot is more beautiful than the ultrasonic welder'.
The machine is widely used in the automotive industry for door panels, map pockets, light-pipe staking, consoles, arm rests and switch clusters; and widely used for medical applications including blood-processing equipments, chemical pumps, fittings, flow meters, IV drug delivery and surgical instruments; consumer product applications including personal computers, portable telephones, laser printers, copy machines, video games, speakers and appliance components; industrial applications including conveyor systems, gears, pulleys, couplings, and motor housings. Thermal presses are also used in the Toy Manufacturing and the Sporting Goods Industry.KEBER heat staking thermal presses can work with a variety of materials including most amorphous and semi-crystalline thermoplastics as well as liquid crystal polymers. Some difficult to weld plastics are well suited to the thermal process including lubricious materials such as PTFE. Soft thermoplastics, such as PE and PP, react favorably to thermal inserting along with brittle materials such as 50% mineral-filled PPO (Ryton) which flakes when subjected to the ultrasonic.
