Heat Staking Machine Manufacturer
Hyusonic is a leading heat staking machine manufacturer with 16+ years of industry expertise, specializing in high-precision plastic joining solutions. Our machines seamlessly integrate metal inserts (nuts, bolts, pins) into thermoplastics, delivering robust, burr-free connections ideal for mass production.
Heat Staking Machine & Equipment
Hyusonic’s heat staking machines are engineered for precise and reliable plastic-to-plastic or plastic-to-metal assembly. Unlike traditional thermal bonding, our systems use controlled temperature and pressure to form permanent joints without damage or residue. Whether you’re working with automotive dashboards, medical housings, or electronic modules, our heat staking machines deliver consistent performance and clean finishes.
Compared to ultrasonic welding, heat staking is ideal for applications where inserts, delicate circuits, or multi-layer materials are involved. Hyusonic supports custom tooling and modular integration into your automated line.
With certifications like CE and ISO, our plastic heat staking solutions are trusted by global manufacturers seeking energy-efficient and eco-friendly alternatives to traditional welding.
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.
The hyusonic heat staking machine adopts an intelligent temperature control system (accuracy ±1℃) and servo motor drive. The riveting position deviation is ≤0.1mm, ensuring uniform molding of plastic pillars without flash. It features customizable automated multi – station synchronous heating, supports 24 – hour continuous operation, and improves efficiency by 300% compared to traditional manual riveting.
Heat staking with induction uses electromagnetic heating to locally melt plastic via metal inserts, enabling fast, precise, and clean joints ideal for automation. In contrast, conventional heat staking (hot plate or air) heats larger areas with less precision, making it more suitable for low-cost, less demanding plastic-to-plastic applications.

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.
