02: Application
Spin welding plastic products together such as floater, paint tank, spherical toy, PP thermos cup, oil filter (for motor bike), water filter, spray connector, thermos bottle interior and etc
Material consideration: Material suitable for spin welding are generally the same as those that can be joined by other friction welding processes, such as vibration welding, semi crystalline thermoplastic are more readily joined using spin welding that ultrasonic, using compatible polymers spin welding is capable of making reliable hermetic seals, joining of dissimilar polymers is possible using the spin weld process, although it generally produces lower strength weld joints, by designing the weld joint with an under cut, the polymer with the lower melting temperature will flow into the undercut, creating a mechanical union, material filler and surface contaminants (e.g. mold release agent) are two factors that will affect consistency and weld repeatability, spin welding is more tolerant of contaminants that ultrasonic welding, spin welding is also less affected by hygroscopic polymers, although they may still require special handing from critical application
Joint design consideration: Part joint must be circular (other part geometry may be non-circular), joint type should be selected to meet welded assembly requirements, joint design should allow for adequate collapse / melting distance, the part to be mounted in the spinning tool on the machine should have driving features so that torque can be transmitted from the tool to the part
Control parameters: Linear speed at the weld joint (based on spin RPM), press (axial) speed, weld depth, hold depth and hold time, the setting for these depends on parts size, material joint design
03: Spin welding machine step
STEP1: The two thermoplastic parts to be welded are loaded into the machine, typically one into the spin tool and the other into a stationary supportive nest call a fixture
STEP2: After a circle is initiated, the spin tool descends toward the fixture while simultaneously accelerating to the programmed weld spin speed (RPM).
STEP3: After the parts come into contact with each other, the tool continues to spin at a constant speed (RPM) while the press forces the parts together, causing the interface to melt, the spinning stops once the programmed condition for ending the weld is met, such as reaching the programmed part collapse distance.
STEP4 Once spinning stops, the hold phase follows, typically consisting of dynamic hold and static hold. During dynamic hold, the press is advanced to further collapse the parts while the plastic material is still molten. During static hold, the press position is maintained while the material cools and solidifies.
STEP5: The spin tool retracts. The two plastic parts are now joined as if molded together and are removed from the machine as one assembly.

Low power consumption
PP LED Bulbs Plastic Welding Machine of spin welding is the preferred technique for thermoplastic parts with a circular axis joint which have high bond strength/hermetic requirement, during spin friction welding, one part is held stationary in a pneumatic holding fixture while a second part is rotary against it under pressure at speeds up to 16000rpm, this resulting friction causes the joining surface to melt and fuse together, producing strong hermetic welds
The PP LED Bulbs Plastic Welding Machine of spin welding machine may be applied infloater, paint tank, spherical toy, PP thermos cup, oil filter (for motor bike),spray connector, Thermos bottle interior...etc.
