Round Plastic Assembly Rotary Friction Welding Spin Welder of Circular Pipe_Tube_Mug_Barrel_Cup_Cartridge Filter Spinning Welder

Round Plastic Assembly Rotary Friction Welding Spin Welder

Round Plastic Assembly Rotary Friction Welding Spin Welder

Round Plastic Assembly Rotary Friction Welding Spin Welder is a method of joining plastic components together with surface spinning friction concentrated in a circular weld joint, one part is spun relative to another, the pressure is applied, causing the melted material displacement, the spinning process stops and the parts continue to be pressed together while they bond in a holistic utility,hermetic seals are also attainable depending upon the materials used and the weld joint configuration, while spin welding works with all thermoplastics and can accommodate virtually any diameter part, it is particularly suited for crystalline resins such as polyethylene and polypropylene

Product description

Plastic spin welding gun

Mainly introduction

Round Plastic Assembly Rotary Friction Welding Spin Welder is a frictional welding technique capable of producing strong, air-tight welds in thermoplastic parts with a circular-axis joint. In this process, friction occurs by rotational motion controlled by either a servo electro-magnetic or pneumatic powered motor or motor control system which regulates the RPM (Revolutions per Minute) and motion control of the system

Mainly application

PP/PE/PVC/nylon filter/water filter/medical filter/oil filter/cup welding and any other circular/tubular shape plastic parts welding to get water-proof and air-tight welding effect, Auto & Motorcycle Filter, Auto & Motorcycle Filter, RO water purifier filter, Water jug and round  work pieces


Ability to weld parts with circular joint that are not easily welded by ultrasonic.

Relatively fast cycle times when compared with other methods.

Compatible with most thermoplastics

Ideal for welding of PP and PE material

Ability to weld several dissimilar materials.

No consumables, fumes or emissions.

High strength, hermetic welds are typical.

Heat confined to weld interface.

Easily automated.

Low cost, quick change tooling.

Low maintenance.

Low power consumption.

Round Plastic Assembly Rotary Friction Welding Spin Welder

Round Plastic Assembly Rotary Friction Welding Spin Welder is the preferred bonding technique for thermoplastic components assembly with a circular axis joint which have bond strength/hermetic requirements, during spin frictional welding, one half is held stationary in a holding fixture while the other half is rotated against it under axial loading pressure at specified velocity, this resulting friction causes the joining surface to melt and fuse together, producing strong hermetic welds

Machine Uses

Round Plastic Assembly Rotary Friction Welding Spin Welder

Round Plastic Assembly Rotary Friction Welding Spin Welder enable thermoplastic parts with spherical joining engagement to melting displacement to achieve assembling process, particularly for welding object made of Semi-crystalline, likely Nylon, PP,PE that are not easy welded by ultrasonic vibration, in addition, this Round Plastic Assembly Rotary Friction Welding Spin Welder obtain preference with its advantages, such as relatively fast cycle times when compared with other methods; compatible with most thermoplastic;ideal for welding of PP,Nylon, PE materials; ability to weld several dissimilar materials;no consumables, fumes and emissions; high strength, hermetic welds are typical; heat confined to weld interface; easily automated;low cost,quick change tooling; low maintenance; and low power consumption

Round Plastic Assembly Rotary Friction Welding Spin Welder

Round Plastic Assembly Rotary Friction Welding Spin Welder produces a welded joint, in many cases, yields a weld strength that is consistently equal to or stronger that any other area of the part, as a result, the weld are can most often to expose to the same strains and stresses as any other area of the part, however, the spin welding joint design roles a predominant performance resulting in cosmetic appearance, and bonding strength, likely, trap flowing-material into groove, design a step to stop melting displacement, design rise or relieve grip to engage the driving actuator and joints should also provide sufficient part-part alignment


How can I buy good quality Round Plastic Assembly Rotary Friction Welding Spin Welder

Firstly: with on line or email conversation, to check the supplier is professional or not, if the supplier has ever supplied the similar machines to other buyer, will be better, don’t save time on studying, don’t stop asking questions before order, more time and efforts you spend, more you can get on the purchasing
