Laser welding how to choose plastic material
by：J&D WATER 2020-03-21
Plastic laser welding for welding object for thermoplastic plastic material, thermoplastic plastics materials is mainly divided into two kinds, one kind is the amorphous plastics, add pigment to the size of transparent material, such as PC and PMMA materials; Another kind is half crystal plastic, add pigment to the size of milky white or fraction of the materials, such as PA, PBT, etc. Laser penetration of the upper layer of plastic, all of the added pigment color plastic, not for 800 - The 1000 nm laser is transparent. If is the use of the amorphous material, the thickness of no specific requirements. And if you are using half as laser penetration layer material, generally through layers of plastic design thickness of welding area not more than 2 mm. The addition of glass fiber have certain influence to laser penetration, to join the more percentage of glass fiber, laser penetration layer thickness to small plastic design. For the lower plastic suction light, ordinary black plastic. Many clients ask color plastic combination between welding, generally speaking, the welding difficulty and the cost follow the table below: color plastic laser welding between ease - the simplest is to use the instinctive quality of pervious to light plastic welding on the black plastic suction light, plastic laser welding technology is the most simple, it is the most low cost. Auto parts using the combination of the most is black laser welding application through the plastic laser welding on the black plastic suction light, its difficulty is to use black laser can penetrate plastic, when choosing materials, laser penetration pieces must use light transmittance qualified laser can penetrate plastic. Difficult is laser welding between the color plastic, while companies can develop color masterbatch of laser can penetrate, but for mass production, the cost is still too high, do not recommend the use of laser welding equipment recommended: preferential deals offer 4007001618 【 Metal laser welding equipment 】 Suitable for all kinds of complex welding, the welding of different equipment and 1 mm thick seam welding; Multi-channel fiber optic mode, welding transfer at the same time; 【 Mould laser welding equipment 】 Applicable mould industrialized, used for precision mold repair, such as digital products, mobile phones, toys, automobile, motorcycle, mold and other mold manufacturing and molding industry. 【 Gold and silver jewelry laser welding 】 Mainly used in jewelry, such as electronics, communications, handicrafts and other industries; 【 Large laser welding 】 Application in automobile body covering parts of compound, such as car door, side wai, window, floor, warehouse, the warehouse before, trunk lid. 【 Automatic laser welding machine 】 Using numerical control software by moving or rotating workpiece computer control of mechanical system, so as to realize automatic welding 【 The laser spot welder 】 Can be used for jewelry, watches and clocks hairspring, integrated circuit lead all kinds of small, precise welding of heat sensitive parts of the YAG laser welding machine 】 High density, the structural weld, precise control, high power density, deep and narrow welds, weld characteristics of bright and beautiful more laser welding laser welding plastic welding equipment
