Detailed Images

Turntable Plastic Spin Welding Machine attains its prevalent because of its predominant characters, such as:the perfectly controlled speed of movement between two parts to be welded;precision control of friction coefficient of material;finally control of pressure exerted during welding; automatic turntable indexing; robot arm of unloading device;accurate angular orientation and collapse distance; reduction of cycle time and repeatability of welds

Machine Uses

Turntable Plastic Spin Welding Machine is a process that joints circular or spherical thermoplastic parts in solid-state by bringing the part interface together when halves assembling process under pressure, with a circular, spinning motion,one have is held stationary in a fixture, while the other is rotated against it under axial loading pressure, the frictional spin generate heat and cause the haves interfaces to melt and fuse together, creating a strong hermetic seal,Turntable Plastic Spin Welding Machine is commonly used in the manufacture of automatic parts, household appliances, and medical device, among other applications, it is a fast and efficient approach to exert robust, reliable and consistent bonds between plastic parts and is ideal for use with wide range of plastic material for mold injection of circular or spherical shaped assembles

Buying guides

01: MATERIAL CONSIDERATIONS

Material is that can be friction (i.e: vibration )welded can also be joined with by spin melting welder, the semicrystalline thermoplastics are more readily joined using spin melting welder that ultrasonic welding, using compatible polymers, spin melting welder is capable of making reliable hermetic seals, for-field welding is easier with spin melting welder that with ultrasonic welding, additional parts can be entrapped between the upper and lower pieces during spin melting weld

Joining of dissimilar polymers is possible using the spin melting welder process although it generally produces lower stretch weld joints, by design the weld joint with an undercut, the polyer with the lower melting temperature will flow into the undercut, creating a mechanical union

Material filler and surface contaminant (e.g. mold release agent) are two factors that will affect consistency and weld repeatability, spin melting welder is more tolerant of contaminants that ultrasonic welding, spin melting welder is also less effected by hygroscopic polymers, although they many still require special handing for critical application, the moisture content can lead to bubble formation in the joint resulting in decreased weld stretch

02: Joint design consideration

021: Part Joint must be on a circular axis

022: Joint design should allow for adequate collapse distance

023: Final orientation of part if necessary

024: If at all possible the upper part would be designed for use with drive features, place for upper tool to grasp the welding parts half

025: The joint area must ne designed so that there is no other part contact interference

03: CONTROL PARAMETERS

There are several primary process control parameters that affect weld quality, there are the surface velocity of the weld joint, press (axial ) speed, weld depth, and hold distance time

04: SURFACE SPEED

For a fixed rotational spin speed (RPM), linear surface speed increases with weld joint diameter, for a fixed weld joint diameter, surface speed increases with motor RPM, smaller diameter parts therefore usually require more FRM that larger parts of the same material, if the surface speed is too low, an adequate amount of head will not be generated to cause sufficient melting, if the speed is too high, excessive heat in the joint could result in material degradation or reduction in viscosity leading to material flow away from the joint

The selection of proper surface speed depends to a larger degree on the material and joint geometry of the parts being welded, some materials, such as PVC, can be readily welded for a wide range of values, while others require a narrow range, commonly quoted values in the literature recommend using

05: PRESS (AXIAL) SPEED

The press speed affects the amount of contact pressure between the parts being welded, which is required to generates frictional heat, the larger the speed. The larger the rate of heat rise, in combination with the surface speed press speed must be high enough to cause melting at the interface as opposed to grinding, but not too high as to damage the parts, excessive press speed can also lead to stalling of the spin motor as more torque is required to maintain constant spin speed

06: WELDING DEPTH

The determination of the proper welding depth is highly dependent on the application, the weld joint is typically designed for a specific weld penetration, ideally, the weld is sufficiently deep to produce a strong hermetically sealed assembly, an excessive depth many lead to the formation of flash (material that is ejected from the joint area during the weld and adheres to the assembly), the drawing out of reinforcing filler material and realignment of the interchain bonds in the weld plane resulting in a weak axial weld joint. And possibly part distortion

Since weld depth affects the joint strength and amount of flash generated, it is important to design the weld joint properly to meet both requirements simultaneously, the incorporation of flash trap features is recommended to produce acceptable appearance without compromising strength

07: HOLD

During the hold phase, vertical press travel initially brings the molten parts closer together (dynamic hold) and then allows the molten material to solidify (static hold), amorphous plastics will normally take longer to solidify that semicrystalline plastic, the dynamic hold distance is typically a small value compare the weld distance, an approximate staring point for initial application setup is 10% of weld distance, the static hold can vary depending on the size of parts, but is usually in the 1-3 seconds range 

Turntable Plastic Spin Welding Machine exerts frictional spin movement to generate heat to melt and fuse the thermoplastic parts, that must designate activity at the circular,spherical joining interface, in the process, the bottom half is held in stationary fixture, the top half rotate inertially in the direction of aginest the bottom fixture with motor driving system, the pneumatic driven actuator apply axial loading pressure to achieve melting replacement and ultimate solidification
