A Closer Look At Our E-Z Sonic Heat Set Inserts
Our E-Z Sonic heat set inserts are ideal for post-molding installation in thermoplastics such as acrylic, polypropylene and PVC. Made with durable brass, each of the ultrasonic threaded inserts we offer comes in tapered or straight designs, depending on the needs of your application. With superior torque and pull-out resistance, you can count on our E-Z LOK’s ultrasonic inserts for thermoplastics to meet the needs of the toughest jobs.
How do you Install Ultrasonic Inserts for Thermoplastics?
E-Z Sonic ultrasonic inserts can be installed ultrasonically or by using a heat driver. For ultrasonic installation, a pneumatic driver will create high-frequency vibrations. The heat generated by these vibrations will melt the plastic, allowing the ultrasonic insert to be installed and held in place by the cooling plastic.
Heat drivers work by heating up the insert to a temperature beyond the melting point of the thermoplastic. Pre-drilled holes are made and the heated ultrasonic insert is pushed into place, melting the plastic around it.
How Do You Determine the Right Size of Ultrasonic Insert for Your Application?
The appropriate size and variety of ultrasonic inserts will depend on your application's requirements. Our experts recommend testing to determine the appropriate size and series of threaded brass inserts you need. E-Z LOK is happy to provide samples to distributors upon request.
What Is the Difference Between E-Z Press and E-Z Sonic Ultrasonic Inserts?
E-Z Sonic ultrasonic inserts for thermoplastics are designed with specific materials and projects in mind. They work well with 3D printing applications and products made from similar materials. They require heat generation to melt the plastic for proper installation.
E-Z Press threaded inserts for plastic are designed for both thermoset plastics and thermoplastics. They come in three varieties — flush, flanged and reverse slot — to match the needs of your application and its hold strength. They are created specifically for "cold" installation using a simple press-in method, rubber mallet or arbor press.
Straight vs. Tapered E-Z Sonic™ Ultrasonic Threaded Inserts
There are two basic designs for E-Z Sonic™ ultrasonic inserts: tapered and straight. Both styles can be installed with either an ultrasonic horn or heat driver, and feature knurl/groove patterns designed for optimum torque and pull-out resistance.
Straight E-Z Sonic™ Ultrasonic Inserts.
Our straight inserts provide superior torque and pull-out resistance, while allowing for thinner boss walls. Flush inserts allows for installation even with or below the material surface; flanged inserts are ideal for electrical connections or for additional pull-out resistance in reverse installations. E-Z Sonic™ straight threaded ultrasonic inserts feature a lead-in pilot to facilitate installation. Machined out of brass, these straight ultrasonic inserts are available with internal threads from #2 to 3/8.
Tapered E-Z Sonic™ Ultrasonic Inserts
Our tapered inserts are designed to reduce installation time, particularly in production runs, while maintaining outstanding performance characteristics. E-Z Sonic™ tapered ultrasonic inserts are machined out of brass and are available in single and double-vane lengths for maximum design flexibility. Internal threads from #2 to 3/8 and M2.5 to M6 are available.
