The technique is also install small elbows into manifolds and to weld extruded tubing to molded attachments for fuel filter linesExtol recently worked on an automotive application that involved welding a hose made from Santoprene, to an air intake made from polypropylene. Welding the hose eliminated the need for pricey, circular steel clamp to attach the hoseIn the appliance industry, spin welding has been used to assemble valve, flow diverters, vacuum cleaner housing and water filters for refrigeratorsSpin welding can also be used to assemble medical devices, extol recently designed a machine to weld talc-filled polypropylene for a fluid recovery device, each half of the assembly was 10 inches long and 3 inches in diameter, "there were few other process options", KEEPLEADER? points out "vibration welding could not do it, because KEEPLEADER? would not be able to address flash control on the inside, spin welding a great solutionFor medical application, it is important to note that spin welding can generate particulates, however, vacuum or compressed air can be used to clear particulates during assembly, adds KEEPLEADER?04: Advantages and disadvantagesAdvantages of Spin Welding: Reproducibility, Large parts maybe welded, high quality weld, and Oxidizing polymers may be weldedDisadvantages of spin welding: At least one of the parts to be welded should have a circular symmetry, minimum rigidity required 05: Spin welding joint designA good spin welding joint should have a weld area equal to or greater that a typical wall section of the part, joints should also provide sufficient part-to part alignmentsUnder designs are most popular proposalsWater Filter Spin Welding Machine 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 materialSpin 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 etcThe one requirements for spin welding, is that the joint interface must be circular, though the parts themselves do not have to be roundSpin 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 weldingHowever, 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 rareFor 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 appearanceDue 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 portsTo 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 welding061: Parts joint must be on a circular axis062: Determine whether or not final orientation of parts required063: Joint design must take account flash/particulate produced during the process064: 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 driver066: Joint design must allow for sufficient collapse distance, insufficient collapse may cause poor weld strength/ quality067: 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 half07: Key parameters of spin weldingThe key parameters of the spin welding process are rotation speed, force, time and displacementSpeed 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 rangeForce 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 forthWeld 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 Detailed Photos Water Filter Spin Welding Machine is the preferred bonding technique for thermoplastic components assembly with a circular axis joint which have bond strength/hermetic requirements, during spin frictional welding, one half is held stationary in a holding fixture while the other half is rotated against it under axial loading pressure at specified velocity, this resulting friction causes the joining surface to melt and fuse together, producing strong hermetic welds Illustration Water Filter Spin Welding Machine produces a welded joint, in many cases, yields a weld strength that is consistently equal to or stronger that any other area of the part, as a result, the weld are can most often to expose to the same strains and stresses as any other area of the part, however, the spin welding joint design roles a predominant performance resulting in cosmetic appearance, and bonding strength, likely, trap flowing-material into groove, design a step to stop melting displacement, design rise or relieve grip to engage the driving actuator and joints should also provide sufficient part-part alignment Machine Uses Water Filter Spin Welding Machine enable thermoplastic parts with spherical joining engagement to melting displacement to achieve assembling process, particularly for welding object made of Semi-crystalline, likely Nylon, PP,PE that are not easy welded by ultrasonic vibration, in addition, this Water Filter Spin Welding Machine obtain preference with its advantages, such as relatively fast cycle times when compared with other methods; compatible with most thermoplastic;ideal for welding of PP,Nylon, PE materials; ability to weld several dissimilar materials;no consumables, fumes and emissions; high strength, hermetic welds are typical; heat confined to weld interface; easily automated;low cost,quick change tooling; low maintenance; and low power consumption Contact Us Water Filter Spin Welding Machine assorts an reliable plastic assembling approach for spherical shaped engaging joint with constrained rotary friction, regardless of the application, engineer are well-advised to contact welding equipment supplier as early in the joining design process,preferable before any molds are cut, this collaborative approach can help manufacturers work through any design constraints and create the ideal joint design,keepleader, we are clients orientation thought, we partner with the end-user to find the best plastic joining solution, additionally, w are application experts with the versatile portfolio of plastic jointing, sealing, and we can select the best technology for your application,kindly consult your individual plastic assembly process with our engineering expert to find what more can we do for you
