Heat Staking & Plastic Assembly

Plastic staking looks simple from the outside. A plastic post passes through another component. A heated tool reshapes the post into a rivet-like head. Once the plastic cools, the two parts remain mechanically locked together. The challenge is not creating one acceptable staking point. The real challenge is producing hundreds of thousands of points with the same height, shape, strength and appearance—without burning the plastic, deforming nearby structures or damaging sensitive components. This is where a pulse heat staking machine may offer an advantage. Unlike a conventional staking system that keeps its tooling continuously hot, pulse heat staking applies electrical energy only when heat is required. The staking tip heats
