Heat Set Inserts vs. Ultrasonic Inserts: Optimizing Fastener Selection for Injection Molded Plastic Assemblies

Threaded Inserts Set in Plastic

Fastener selection plays a vital role in determining long-term part integrity, assembly repeatability, and structural performance. Among the most widely used fastening methods for thermoplastics are heat set inserts and ultrasonic inserts. Both methods deliver durable, threaded metal connections, but they differ in how they interact with molded materials and
