Rotary Friction Plastic Welding Machine
01: Application
Rotary Friction Plastic Welding Machine is a welding technique that uses heat generated by rotational friction at the joint line to weld thermoplastic parts, particularly for PP,PE,PET,Nylon and other semi-crystalline material, which is not suitable for ultrasonic vibration bonding, in this technique, friction is used to heat the parts to be welded, it applies axis symmetric pressure as it rotates one part against the other stationary part
Rotary Friction Plastic Welding Machine has obvious advantages, such as: ability to weld parts with circular joint that are not easily welded by ultrasonic vibration welder; relatively fast cycle times when compared with other approaches; compatible with most thermoplastic, typically for PP,PE,PET,Nylon and other semi-crystalline material;Ideal for welding of Nylon, GS filled, PP and PE materials; ability to weld several dissimilar materials; no consumable, fumes or emissions during fusion, because of its plasticized solidification in sold-status;high strength, hermetic welds are typical in aesthetic appearance; heat confined to weld interface; easily automated; low cost, quick change tooling kits; low maintenance and low power consumption
Rotary Friction Plastic Welding Machine has wider welding scenarios, likely automotive: Fuel system filtration, air duct, filter bowls and oil fill tube components; appliance: water valves, refrigeration water filtration, and toilet components; irrigation system: sprinklers components; pool and spa: filtration components; beverage: dispensing, beverage cups; medical: syringes

Spin welding can join any thermoplastic, whether filled or unfilled, amorphous or semi-crystalline.
Spin welding can join ABS, PVC polypropylene, polyethylene and glass-filled nylon, to name a few; they have difficulty with slippery plastic, such as Delrin or ultra-high-molecular polyethylene.
If you have very hard parts, like polycarbonate or acetal, it can take a lot of torque to get the materials to start melting, KEEPLEADER™ experiencing, it is easier to spin welding larger parts made from softer materials than harder material
Spin welding can even weld dissimilar materials, KEEPLEADER™ addressing, the parts don't have to be as chemically similar as they do with ultrasonic welding, in terms of material compatibility, spin welding is more like vibration welding, KEEPLEADER™ have ever done a spin welding joint that was polyethylene to polypropylene, it was a mechanical joint with a hermetic seal that could hold a pressure of 30pssi, something you would never see with ultrasonic welding. Spine welding also can joint tall parts represent far-field welds, which is problem for ultrasonic welding, spin welding can accommodate parts with contours, openings or extensions and etc
The one requirements for spin welding, is that the joint interface must be circular, though the parts themselves do not have to be round
Spin welding melts and moves material than other plastic joining methods, as much as three times more. That makes the technology ideal for creating pressure-resistant, hermetically sealed joints, KEEPLEADER™ has ever instruct pressure testing of 100psi after spin welding
However, more melted material means more flash, and engineers will have to account for that in their joint designs, the key with spin welding is to visualize where the flash is going to go and how to hide it. Because of centrifugal force, the flash typically wants to move outside the joint, the best designs for spin welding are share joints, tongue and groove joints and scarf joints, butter joints can also be accomplished, but they are rare
For the best weld strength, the best performance and least amount of torque draw, you should always use a shear joint, if you know your molds are not great, if you have some warpage on your parts, or if you are not sure the parts will fit together consistently that is when you want to use a scarf joint. A shear joint consists of two walls that contact each other at an angle with an interface fit, shear joints can be designed with flash traps to capture excess molten plastic, and a shirt can also be designed into the tap parts to hide the joint line for a more cosmetic appearance
Due to the "active" nature of the process, it is a good idea to include a feature: a rib or a recess to help the drive head spin the top half and aid the fixture in holding the bottom half, sometimes, the drive head can key on a port, fitting or other feature sticking out from the part, if the feature is robust enough, for example grip, the drive head and fixture can also be modified with spring-loaded ball detents, a Flexane coating, or vacuum ports
To prevent deflection, the tooling should also support the sides of the assembly, irrespective of how thick the walls are, softer plastics are easy to melt, but are also prone to deflection.
Regardless of the application, engineers are well-advised to contact KEEPLEADER™ as early in the design process as possible-preferably before any molds are cut, an application engineer can help you work through drive features and joint design, its becomes a collaborative process, there's always back and forth between the customer's design constrains and the ideal joint design.
06: Design consideration of spin welding
061: Parts joint must be on a circular axis
062: Determine whether or not final orientation of parts required
063: Joint design must take account flash/particulate produced during the process
064: Preferably, upper part half will be designed for use with drive features (areas for driver to engage parts)
065: Ideal parting line will be parallel to the force applied by the driver
066: Joint design must allow for sufficient collapse distance, insufficient collapse may cause poor weld strength/ quality
067: Material selection may have an impact on welded type (orientation or inertial)
068: Part must be designed so that there is no contact (other than the joint area) between the spinning part half and the clamping part half
07: Key parameters of spin welding
The key parameters of the spin welding process are rotation speed, force, time and displacement
Speed and force vary with the size and composition of the parts, says Mr. Leo applications engineer at KEEPLEADER™ with a servomotor spin welding, speed can range from 250 to 5000rpm. An inertia spin welding can reach speeds of 10000rpm.
Although it may seem, larger diameter parts need less speed that small ones, says Mr. Leo indeed, for large-part application, the electric motor might be equipped with a gear reducer to swap speed for torque
You have to think in terms of surface feet per minute, rather than rotations per minute, KEEPLEADER™ address " the optimal surface feet per minute setting for nylon is different from ABS or Polypropylene, KEEPLEADER doesn't see many application over 5000rmp and 1000~2000rpm is pretty typical range
Force is usually minimal, the more pressure you apply when bringing the parts together, the more the assembly wants to resist torque, KEEPLEADER™ suggests " if you rub the palms of your hands together lightly, they will get hot pretty quick, squeeze them together hard, and it's difficulty to move your palms back and forth
Weld and hold times can also be important, KEEPLEADER™ has ever experienced huge improvements in welding quality just by changing the hold parameters, because you melting a large amount of material, it is important to control how it melts, usually, you want to collapse the parts while they are melting, because plastic shrinks as it solidifies, you have to make sure you don't have any voids in the parts
