Answer: Not all plastic parts of the plastic laser welding machine can be welded.
First of all, plastics can be divided into thermoplastics and thermosetting plastics
Thermoplastic: plastic that melts and cools after heating, and then reheats and melts again, that is to say, thermoplastic is a reversible plastic with weldability; For thermoplastics, plastic laser welding has many advantages such as non-contact, watertight, airtight, fast welding speed, high precision, no flash, no residue and so on.
Thermosetting plastics: Thermosetting plastics are characterized by the addition of minerals, lime, glass fiber and other fillers or strengthening substances in the molding process to enhance properties, thermosetting plastics can be welded with plastic laser welding machine, mainly to see the proportion of thermosetting plastic fillers, if the proportion of fillers in thermosetting plastics such as glass fiber, carbon fiber, flame retardant is too high. When the degree of crystallization of this type of plastic is high, it is not good or can not be welded, because when the filling material in the thermosetting plastic exceeds a certain proportion, in the laser welding process, the two plastic components of the weld part of the plastic melt together, but the glass fiber and other substances in the plastic can not melt together, and the welded product may not be strong enough to meet the needs of use.
In summary, the plastic laser welding machine is suitable for welding thermoplastic materials. Common welding plastics are PBT, PC, nylon, PVC and so on.
