Servo Spin Welder Orienting Rotation Plastic Welding Machine

Servo Spin Welder Orienting Rotation Plastic Welding Machine

Servo Spin Welder Orienting Rotation Plastic Welding Machine is an electric press system utilizing servo motors to provide precise control and accuracy for welding assemblies with circular weld joints, by utilizing state of the intellectual servo programmable logic control, this Servo Spin Welder Orienting Rotation Plastic Welding Machine provides angular advertent orientation and overall assembly height consistency, controllable melting assembly mode can b enabled during the weld phase, in which the motion of the vertical axis is coordinated with that of the spin axis to match the rate of melt of the material being welded

Machine Description

Servo Spin Welder Orienting Rotation Plastic Welding Machine


Servo Spin Welder Orienting Rotation Plastic Welding Machine belongs to solid state frictional melting assemble of thermoplastic parts with circular or cylindrical joint interface, its process is achieved in case of thermoplastic parts with rotational symmetrical joint surfaces are rubbed together under pressure in an unidirectional circular motion, normally, one half is held stationary while the other is rotated, the heat that is generated during this process melts the plastic at the interface, forming a weld upon cooling, Servo Spin Welder Orienting Rotation Plastic Welding Machine is a simple and highly energy efficient process, there is little excess heat generated, which means that cooling times are short, this makes the process well suited to automated assembly line application, strong, hermetic joints can be produced, which are frequently stronger that the parent parts, no foreign materials are introduced into the weld and no environmental considerations are necessary, as in solvent sealing or adhesive bonding, the first reported application for Servo Spin Welder Orienting Rotation Plastic Welding Machine was in the manufacture of fluid-filled compasses, where welding was carried out beneath of the surface of liquid, the process can therefore be used for sealing a liquid in a container, other applications include fuel filters, check valves, truck lights, aerosol cylinders, and floats, Servo Spin Welder Orienting Rotation Plastic Welding Machine is also used for assembling structural components, connecting ventilation pipes to blow-molded fuel tanks, and welding tops and bottoms on containers, almost all thermoplastic can be joined with axisymmetric interface whatever angular orientation or not

05.4: Operator is permitted to release cycle activation switches after part to part contact is made

05.5:Servo motor spins parts at user programmed RPM for the number of user-programmed revolution (or user-programmed timer, collapse distance, or absolute distance) and terminates rotation when desired weld criteria are reached

05.6: Welded parts cool/melted plastic solidified under pressure

05.7: Actuator retracts to home position, and servo slowly rotates to user-programmed home position

05.8: Operator removes welded parts from fixture

Servo Spin Welder Orienting Rotation Plastic Welding Machine

Servo Spin Welder Orienting Rotation Plastic Welding Machine produces a welded joint which, in many cases, yields a weld strength that is consistently equal to or stronger than any other area of the part, as a result, the weld area can most often be expose to the same strains and stresses as any other area of the part, Servo Spin Welder Orienting Rotation Plastic Welding Machine involves configuration and consideration in its designation of welding object and tooling sets, such as spin welding joint design: a good welding joint should has a weld area equal to or greater than a typical well section of the part, joints should also provide sufficient part-to-part alignment; Spin welding tooling sets: Driver, custom made tool used to spin the part and generate the weld, driver commonly use raised or relieved surface to engage raised or relieved drive features on the spinning art half, taped silicone drivers can also be used on parts that do not have risen or relieved drive features; holding fixture, the non-rotating part half must be held securely so that one part half does not rotate and remains alignment with the spinning part half, part details such as protrusion and lugs/ribs on the outside of the part aid greatly in preventing rotation.

Machine Uses

Servo Spin Welder Orienting Rotation Plastic Welding Machine

Servo Spin Welder Orienting Rotation Plastic Welding Machine gains prevalent application of semi-crystalline thermoplastic assembling process with circular or spherical joining interface, such as manifold valves, thermal cup, water/oil filtering cartridge, jug, barrel, and round container, Servo Spin Welder Orienting Rotation Plastic Welding Machine has prominent melting results because of #1: Perfect mastery of stopping values; #2: repeatability of the process in consistent welding strength; #3: mastery of penetration speed; #4: optimized productivity gain; #5: standing-along working status for freely arrangement of productive scenario

Tech Illustration

Servo Spin Welder Orienting Rotation Plastic Welding Machine

Servo Spin Welder Orienting Rotation Plastic Welding Machine is a process that joins circular, round thermoplastic injection-molded parts by bringing the part interface together, under pressure of servo-motor driven, with a circular, spinning motion to achieve displacement motion at sharing interface, one half is held stationary in a fixture cavity/anvil, which the other half is rotated against it under axial loading pressure, the frictional spin heat that is generated caused the part interfaces to melt and fuse together, because of flash trap slot is designed in the joints, hence, no overflow happens. However, creating a strong and hermetic seal
