1, hot plate welding method:
Principle: through the metal hot plate directly on the plastic welding heating surface, up to a certain point, hot plate exit, then on two pieces of plastic to exert a certain pressure, reaches the welding ends
Suitable for: for PE, PP, nylon, ABS thermoplastic plastic workpiece materials, such as lights, water tank, balancing ring for washing machine, spray cans and other
2, rotary welding mode
Principle: motor rotating at high speed through the plastic parts friction generated by high temperature, plastic workpiece contacting surface melting, then by external pressure, driving to make the upper and lower workpiece solidified as a whole, to become permanent binding
Suitable for: home reverse osmosis filter (filter, industrial filter, pharmaceutical filter, active carbon filter.........)
Plastic cup (cup double, beer cups, cups, vases, containers......)
Gardening supplies (water spray head, mist, water head......)
Ball (ball hole and other exercise ball, floating ball, toy ball......)
3, ultrasonic welding mode:
Principle: ultrasonic plastic welding principle is produced by the generator high voltage, high frequency signal, using energy welding head (HOM) transfer to the plastic processing objects, through the workpiece surface and internal molecular friction between the plastic contact surface to generate high temperature, at the moment to make plastic joints quickly dissolved, exchange, in a second complete fusion process
Application: widely used in electronics, electrical appliances, auto parts, plastic toys, stationery, handicrafts, cosmetics and other industries
In 4, high frequency welding method
Principle: the main principle is from the tube oscillator generates a high frequency electric field plastic polar molecular torsion repeated to generate friction heat, so as to achieve the aim of weld
Suitable for: all kinds of polyvinyl chloride (PVC) consisting mainly of plastic, which are products of footwear, trademarks, stickers, raincoat, rain, an umbrella sail, purses, handbags, beach bags, stationery, famous brand, inflatable toys, water, steam, locomotive seat cushion, shade panels, door panels, special hard shell vacuum packaging
5, hot melt welding mode
Principle: directly through the heating plate for heating element for heating, dissolving, reach the riveting or metal implant purposes
Application: suitable for screw implants and hot riveting pressure, such as a switch, mobile phone, all kinds of electronic products.
6 plastic machine is mainly used for packing blister card package with heat, using pulsed heating principle (36V voltage causes a bakelite mold heating) according to the size of the workpiece (the heat seal area) to select different output current and conduction time, and then cooling the pressure case complete sealing packaging.Packaging products transparent appearance, fast packaging.
The main application of exquisite packaging, stationery, daily necessities, toys, cosmetics, industrial products and hardware products, small tools, sealed into a beautiful and transparent coat, trying to make the packed articles show a variety of advantages, stick out a mile
