Management theory and practice don’t always match, and few people know this better than the individuals who oversee assembly lines. Their real-world experience has taught them that the best method to achieve success always depends on several application-specific factors. Among them are part size and shape, available automation, required cycle time and the materials being joined.
Plastic parts, for example, can be assembled using various welding techniques. But, when the part is made of a semi-crystalline material and has a complex geometry with a circular joint interface, spin welding, a type of friction welding, is the method of choice.
