What Is Heat Staking
Heat staking is an intelligent thermal staking technology that goes beyond traditional heat-press methods. By integrating thermal conduction, ultrasonic pre-excitation, and laser positioning, the process enables precise deformation control of plastic staking features at sub-millimeter scale. This ensures secure, non-damaging mechanical fastening between plastics and materials such as metals or composites.

Customer FAQs
What is the difference between ultrasonic welding and heat staking?
Ultrasonic welding uses high-frequency vibrations to generate heat, fusing materials (plastic/metal) by molecular agitation, ideal for precise, rapid joins in electronics. Heat staking heats a tool to melt plastic, forming a boss or stud to fasten components, suitable for structural assembly in automotive/household products, relying on thermal conduction for bonding.
What is the process of heat stacking?
Heat staking process: 1. Preheat a metal tool tip to specific temperature. 2. Position the tool over plastic components with bosses/studs. 3. Press the tool to melt the plastic tip via thermal conduction. 4. Shape the melted plastic into a head (e.g., mushroom form) by applying pressure. 5. Cool the area to cure the joint, fastening components together. Ideal for permanent plastic assembly in automotive/electronics.
What temperature is heat staking?
Heat staking temperature varies by plastic material: – ABS: 200–250°C (392–482°F) – Polycarbonate (PC): 250–300°C (482–572°F) – Polypropylene (PP): 160–200°C (320–392°F) – Nylon: 220–280°C (428–536°F). Factors like material thickness and tool design also influence optimal temperature, which must balance melting efficiency with avoiding material degradation.
What materials are heat staking?
- Thermoplastics (melted to form the joint).
- Metals/other components (e.g., PCB, busbars) that are fastened via the melted plastic.
So, the materials being heat-staked are thermoplastics, but the process often joins them to metal or other parts.
What is hot staking?
Hot staking (also known as heat staking) is a thermal joining process used to permanently fasten components, typically metal parts (e.g., PCBs, busbars, electrical contacts) to thermoplastic materials. The process relies on heating a tool (often a metal tip) to a specific temperature, then applying it to plastic bosses or studs on the workpiece. The heat melts the thermoplastic, which is then shaped (e.g., into a mushroom head) under pressure to secure the adjacent component. Once cooled, the solidified plastic forms a strong mechanical joint.
