Machine Uses

For Orienting Spin Welder Plastic Welding Machine,In selection of motor's power and dominant limit of torque govern joint design with primary factors, such as what type of material is to be welded; what is the overall part size and configuration; what are the ultimate stipulation of the assembling parts; is a structural bond desired;and if so, what load forces it need to resist;Is a hermetic seal required; if so, to what pressure; Does the assembly require a visually attractive appearance; Is flash or particulate objectionable inside and or outside; Does turning direction required;Does demand auto indexing;and, Any other requirements
 

Tech Illustration

 

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 

Orienting Spin Welder Plastic Welding Machine usually takes 5 steps in frictional welding assembly, 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 called fixture; step2: After a cycle is initiated, the spin tool descends toward the fixture while simultaneously accelerating to the programmed weld spin speed,Viz: RPM;step3: after the parts come into contact each others, the tool continues to spin at a constant speed while the press forces the parts together, causing the interface to melt in frictional spin, the spinning stops once the programmed condition for ending the weld is met, such as reaching the programmed part collapse distance,Viz overlap distance;step 4:once spinning stops, the hold phase follows, typically consisting of dynamic hold and static hold, during dynamic hod, the process is advanced to further collapse the part while the plastic material is still molten,during static hold, the press position is maintained while cools and solidifies;step 5: the spin tool retracts,the two plastic halves are now joined as if molded together and are eliminated from the fixture as one assembly
