Rotary Friction Welder Plastic Spin Welding Machine of Frictional Rotation Fusion Equipment for Nylon_PP_PE Circular/Round Parts

Rotary Friction Welder Plastic Spin Welding Machine

Rotary Friction Welder Plastic Spin Welding Machine includes rotating one parts, also named driving actuator in continuous circular motion against another fixed part, name fixture, under axial force, in all thermoplastic spin friction welding processes, the heat generated by the frictional action must be sufficient to melt and flow the plastic at the weld interface, sufficient heat is generated by a combination of welding time, welding force and interface velocity, determined by rotational motion

Product uses

Rotary Friction Welder Plastic Spin Welding Machine is used to weld thermoplastic parts with rotational symmetrical joining surfaces, its joints must be circular, cylindrical, tubular, round and spherical shaped interface to apply rotational friction, the welding of the two halves in one part is due to the simultaneous application of rotation and axial pressure, thus, the friction obtained generates the heat necessary for their welding and fusing, Rotary Friction Welder Plastic Spin Welding Machine is ideal for PP, Nylon,PE,Polyester and any other semi-crystalline material which is much more difficulty to weld by ultrasonic, and its bonding result in air-tight and water-proof

Function illustration

Rotary Friction Welder Plastic Spin Welding Machine has simple process, but produce air-tight, water-proof joints, in 1st, the parts of the two halves are brought together and axial force is applied, the inter-facial friction begins but initially, no material flows, in 2nd, the welding zone material starts to melt and material displacement to the edge of the weld begins, in 3rd, the process is a steady state phase, the material is pushed out from the weld at a constant rate, in 4th, the process is the cooling phase when the inter-facial friction is stopped but the force is still applied to consolidate the active bonding, an alternative to welding by time is to weld by displacement, inter-facial friction is applied to components being welded until a fixed material displacement is achieved, this would typically 1 to 2mm, but would depend on the flatness of components being welded, undulation in the welding interface would need to be taken into consideration when setting the weld displacement
