What is the hot plate welding |
The heat generated by the hot plate junction of compression softening surface welding method.
For simple device, high strength, welding, since the ancient times was used for welding of large-scale product. |

Hot plate welding characteristics
|
☆advantages
- Weld strength, high efficiency (in various welding method of optimal)
- Can undertake airtight, good reliability
- Products, welding parts of the design are relatively easy to shape
★faults
- The heat generated by the hot plate to make long cycle, soften.
- In the hot plate of stickup resin will appear wiredrawing phenomenon (must have corresponding countermeasures of plastic paste)
- When different kinds of resin or metal and resin, timeliness connect intensity.

| Welding process |
Device is a hot plate and pressure etc. |
| |
First stage: make contact with hot plate, the products of the melt glue
The second stage: keep in touch, the melting cooling solidification.

Welding parts for flat
Flash show depth shape
Hidden flash shape

|
| The welding conditions |
The temperature setting basically than resin melting
|
|
| |
Hot plate with the products To ensure the minimum pressure junction products
- When the voltage produced and: flash
|
|
High pressure will flash |
| |
When using the welding machine without pressure adjustment, it depends on the tool. (for example: stop actuator etc.) |
|
|
| |
Decided to soften the time Can make joints softening of the time
- The softening 1mm high or reference
|
|
|
| |
Mechanical drive speed Complete softening = > products welding engineering
|
|
| |
Softening of the products The lowest pressure setting needed, welding depth
- Stress, can cause melting resin was extrusion, become the reasons of the low intensity.

Drawing countermeasures
(to prevent stick in hot plate) pay |
In pce (PTFE) film or hot plate coating processing. PTFE
Note: the hot plate will be made after the mirror surface coating PTFE.
