The best method for staking plastic parts depends on the material, part design, cycle time requirements and cosmetic needs.
Staking is an ideal process for assembling plastic parts. It's quick and inexpensive. It can join dissimilar materials. It eliminates the cost of fasteners and adhesives, and it allows engineers to loosen the tolerances for molded parts. Although a staked joint cannot be reopened, it can be cut or broken relatively easily to permit disassembly and recycling.
