The pp plastic board cannot be separated from welding when used. This can help the board to have stable performance. However, the requirements for the production of the board are different for different welding methods, and the methods are relatively different. So today we will Let's understand the welding methods of this product together, which will help you to use it differently according to different requirements in later use.
1. Hot gas welding technology is usually used to weld plastic pipes, sheets or semi-finished products instead of injection-molded parts. However, many thermoplastic molded parts, especially thermoplastic automotive discs, are repaired using hot gas welding techniques. In addition, hot gas welding is sometimes used to make plastic-like molded parts. PP plastic plate welding (for flat parts) is a thermoplastic welding process that uses electric heating metal molds to make the surfaces of the connected plastic parts soft. Suitable for almost all large and small thermoplastic parts. Particularly suitable for welding softer semi-crystalline thermoplastics such as PE or PP. Because different mold surface temperature energy names are applicable to two different thermoplastic materials, this process is relatively long, small parts take 15s, and large parts take several minutes.
2, hot gas welding
Hot gas welding is a welding method widely used to connect pp plastic plates and sheets to produce large parts. It is suitable for the repair of small injection-molded parts, thermoplastic parts and the manufacture of prototype parts that require local assembly. It is important to produce electrodes with the same polymer brand as the part being welded.
3.Extrusion welding
Extrusion welding is a welding method developed from hot gas welding. Mainly more automatic welding of sheet structure.
4, bonding
Adhesives can be used to connect plastic parts of the same raw polymer, generally used to join parts made of different materials. Connect thermoset plastic parts to each other, or connect plastic parts to metal.
Through the above analysis, when welding the pp plastic board, we can analyze the specific problems according to our own environment and choose a suitable welding method for processing. The purpose is to make the product performance firm. It is recommended that everyone follow the correct steps when welding, do not skip operations, and avoid performance damage.
