Hot plate welding machine
Hot-plate welding is one of the simplest and most versatile method for joining plastic parts. It works well with small or large, flat or contoured ones. It can handle single or multiple assemblies at once. Unlike other methods like ultrasonic or vibration welding, hot-plate welding is often more effective.
In the automotive industry, it’s used for assembling headlights, taillights, ductwork, manifolds, batteries, fuel tanks, filter housings, and coolant and fluid reservoirs. Appliance manufacturers use it for spray arms, agitators, balance rings, brushes, and reservoirs. It’s also employed in the hardware industry for window and door frames. Medical device makers use hot plate welding for sharps containers and foot massagers. Even larger items like barrels, pallets, and crates can be made using this technique.

- Precision guide rails: upper and lower slide movement is guided by four sets of precision guide rails.
- Servo geared motors
- Safe hanging teeth: to ensure that the slide can be safely protected when stopping in any position
- Displacement sensors: Displacement sensors guarantee absolute slide movement
- Precision rack and pinion: the slide movement is driven by two sets of rack and pinion. Good guarantee of the parallelism of the slide movement

The Process
Hot plate welding is a simple process that involves using a heated platen with customized heat inserts that match the shape of the weld plane. The plastic parts to be joined are placed against the heated plate, which causes the joint interface to melt and soften. Once the plastic reaches the desired temperature, the parts are pressed together, completing the welding process. This direct thermal contact method ensures a clean and seamless join between the plastic parts.

If the lens using PC material contact welding wire drawing serious, it is recommended to use TR welding, noncontact does not exist wire drawing problem.

Jfortune reply:
It can all use low temperature welding, hot plate with Teflon coating. The cost will be increased a little correspondingly, and the welding cycle will also increase. The total welding cycle is about 55 seconds (excluding manual loading and unloading parts).
In addition, the equipment requirements will increase, the need to speed up the equipment’s running: because low temperature welding, while product cooling needs accelerate, so the cost of equipment will increase a little too.
