Product Description
Heat-Stake & Ultrasonic Insert Nut Solution | Connection Design & Parameter Optimization for ABS, PC, PP, PA Plastics
1. Hot-melt copper nuts: Quick details
Tingfeng Hardware provides high-performance heat-set nuts (also known as insert nuts or ultrasonic nuts) for plastic components. These nuts, with their specially textured (e.g., knurled, finned) welding areas, are embedded into the plastic using ultrasonic vibration or heat pressing. After cooling, they form a permanent threaded connection with strength far exceeding traditional snap fasteners or adhesives. This process is fast, clean, and automatable, making it particularly suitable for plastic products requiring resistance to torque and pull-out forces, such as automotive interior parts, appliance housings, and medical devices. It is an economical and efficient solution for achieving reliable metal-to-plastic connections.
2.Hot-melt copper nuts: Product Description
The successful application of heat-staking nuts depends on the perfect combination of nut design, plastic material, and installation process. We are not only a supplier but also your process consultant in this field. Based on the melting characteristics of the target plastic (such as ABS, PC, PP, PA), we design different shapes and sizes of the welding zone to optimize the flow and encapsulation of the molten plastic, ensuring maximum contact area and rotational resistance. We provide comprehensive technical support, including recommending appropriate installation energy, time, and pressure parameters. We can also customize and optimize the nuts according to your production line (ultrasonic welding machine, heat staking machine) to ensure stable and consistent embedding quality and thread performance, preventing plastic cracking or nut loosening.
3.Hot-melt copper nuts: Product Features & Advantage
|
Feature |
Advantage to You |
|
Excellent Torque-Out & Pull-Out Strength |
Molten plastic fills and solidifies within the nut’s knurls, fins, or grooves, creating a powerful mechanical interlock. The torque-out and pull-out forces are typically several times the strength of the plastic itself, providing plastic parts with connection reliability comparable to metal components. |
|
Fast Installation Cycle & Clean Process |
The ultrasonic heat sealing single-point cycle typically lasts 0.5-2 seconds, and hot pressing only takes a few seconds, far exceeding the curing time of threaded adhesives. The process is free of smoke and dust and chemical volatile substances, meeting the requirements of clean production and easily integrated into automated assembly lines. |
|
No Damage to Plastic Appearance or Structure |
The heat is concentrated in the nut welding area, quickly melting the local plastic and completing the embedding process. This results in minimal overall thermal impact on the plastic part, preventing back-side bulging or cracks caused by stress concentration, and maintaining the product's complete and aesthetically pleasing appearance. |
|
Wide Compatibility with Plastic Materials |
By adjusting the nut’s surface texture and installation parameters, it can be adapted to the vast majority of thermoplastics (including glass-fiber reinforced materials). We offer material matching testing services to find the optimal nut-plastic combination for you. |
4Hot-melt copper nuts:.Product Specification
|
Feature |
Advantage to You |
|
High Thermal Conductivity & Superior Embedding Performance |
Brass has significantly higher thermal conductivity than steel. During the hot melting process (ultrasonic or heat staking), heat transfers rapidly and evenly to the interface, causing the plastic (or composite material) to melt quickly and fully encapsulate the nut's locking features (knurls, grooves). This creates a dense and robust molecular bond, achieving extremely high torque-out and pull-out resistance. |
|
Excellent Corrosion Resistance & Long-Term Conductivity |
Brass inherently offers good resistance to corrosion from atmosphere, water, and many media. Additional surface treatments like nickel plating can be applied for enhanced protection. Moreover, the inherent excellent conductivity of copper alloy makes the nut reliable for scenarios requiring electrical grounding or signal transmission in embedded connections. |
|
Complex Non-Standard Structures & Full-Size Customization |
We specialize in non-standard customization, going beyond simple round nuts. We can produce complex brass nuts with flanges, multi-step profiles, special contours, non-standard threads (e.g., fine pitch, special pitch), or integrated electrical contacts. Full-size customization from sub-M2 micro parts to M20 and above large parts is supported to meet your unique design requirements. |
|
In-Depth Process Collaboration & DFM Analysis |
We are not just a manufacturer, but your process partner.针对 your substrate material (high-temperature plastics, engineering composites, etc.) and assembly conditions, we provide free Design for Manufacturability (DFM) analysis for the embedding process. We optimize the nut's locking tooth profile, pilot angle, and fusion zone design to ensure successful embedding in one attempt, preventing substrate cracking or connection failure. |
|
Stringent Material Control & Performance Validation |
We use high-quality H59, H62, or superior brass grades, ensuring material consistency from the source. Material certificates can be provided per batch. Equipped with torque-out and pull-out force testers, we can provide performance verification reports for custom products, ensuring they meet the most stringent mechanical requirements on your drawings |
5.Hot-melt copper nuts:Product Application
Our hot-melt brass nuts are precision components that solve unique embedding and connection challenges, suitable for:
Precision instruments and micro-devices: Providing reliable threaded metal inserts for sensor, optics, or micro-motor housings, with extremely precise internal space for robust component connections and accurate positioning.
High-end consumer electronics heat dissipation structures: Embedded in aluminum alloy heat sinks or housings, utilizing copper's excellent conductivity to provide mounting points for chips and power components, offering both robust fixation and efficient heat dissipation.
Outdoor and harsh environment electronics: Used in communication equipment housings, waterproof connector housings, etc., their corrosion resistance ensures long-term stable electrical connections and mechanical strength in humid and salt spray environments.
Special vehicle and mobile device interiors: In space-constrained vehicle control units, suspension system sensors, or drone fuselages, hot-melt brass nuts replace traditional welding methods, achieving high-strength threaded connections in lightweight components.
