Brass Ultrasonic Inserts are advanced threaded fasteners engineered for integration into thermoplastic parts using ultrasonic energy. During the ultrasonic insertion process, the insert is heated by high-frequency vibrations, which locally melts the plastic. As the plastic reflows and solidifies, it forms a secure, permanent bond around the insert—resulting in a robust metal-to-plastic threaded connection. We are one of the largest manufacturers and suppliers of Ultrasonic Inserts from India. Our manufacturing plant in Jamnagar, India, offers a wide range of Ultrasonic Inserts, and we export our products worldwide to some of the most quality-conscious markets in the world.

Key Features of Ultrasonic Inserts
Precision Integration:
Ultrasonic Inserts are embedded directly into molded components during the production process, eliminating the need for secondary machining. This ensures precise thread alignment and consistent quality across large production runs.High-Quality Materials:
Typically manufactured from premium brass (with optional stainless steel variants), these inserts offer excellent corrosion resistance and durability, making them ideal for demanding applications in consumer electronics, automotive components, and industrial products.Ultrasonic Installation:
The ultrasonic process uses high-frequency vibrations to melt the surrounding plastic locally, allowing the insert to be locked in place as the material re-solidifies. This creates a permanent, high-strength threaded connection with minimal thermal impact on the host part.Enhanced Mechanical Strength:
By replacing weaker plastic threads with a metal insert, the overall load-bearing capacity and resistance to wear or stripping are significantly improved.
Technical Specifications (Example Values)
| Parameter | Specification (Typical) |
|---|---|
| Material | High-quality brass (e.g., UNS CA‑360) or stainless steel |
| Thread Sizes Available | Typically available from M3 to M12 (custom sizes available) |
| Insert Length | Approximately 1.25–1.5× the nominal thread diameter |
| Installation Method | Ultrasonic insertion (using ultrasonic welding equipment) |
| Operating Temperature | Suitable for typical molded part environments (e.g., –40°C to +100°C) |
Note: Exact dimensions and thread pitches can be tailored to meet specific application requirements.
