What are the precautions for welding Jiangmen engineering plastics

2019-06-15 1212

No matter which welding method is used, the principle is the same, that is, the melting state is formed at the welding position of engineering plastics to varying degrees, and then the melting positions are connected together. After curing, the welding effect is achieved. Then, the matters needing attention in the welding process are:

1. Pretreatment of welding position: before welding, the welding position shall be cleaned to remove adhered impurities and oxidized skin.

2. Welding viewpoint design: for welding with viewpoint, the viewpoint and reserved amount shall be set accordingly to avoid affecting the welding effect.

3. Orientation calibration: because the welding process involves pressurization and other operations, the displacement occurs at all times. Maintaining a stable and correct orientation will directly affect the application after welding.

4. Pressure maintaining time: engineering plastics have a certain time from melting to curing. Appropriate pressure maintaining time shall be set according to different raw materials, thickness and other conditions to avoid adverse welding effects.

5. Melting temperature control: because the melting points of different materials are different, the lack of molten materials will occur when the temperature is too low, and excessive reactions will occur when the temperature is too high. Therefore, it is necessary to select the relative melting temperature according to the corresponding materials.

With the continuous development of engineering plastics and the continuous promotion of welding skills, engineering plastics welding skills are also developing. It is believed that future skills will be able to weld engineering plastics better and faster, bringing greater convenience to production and life.
