(UHL_HHL) BRASS THREADED INSERTS FOR HEAT STAKING AND PLASTIC COMPONENTS

Brass threaded inserts make it possible to create a durable metal thread inside plastic components, improving the strength and reliability of the fastening.

Compared with a thread formed directly in the plastic, they provide greater wear resistance, improved long-term holding performance, and reliable operation even after repeated fastening and unfastening cycles.

For this reason, they are an ideal solution for industrial applications requiring durable, secure, and repeatable assemblies, helping extend the service life of the component while reducing the risk of damage to the plastic material.

UHL/HHL threaded inserts are designed to create reliable metal threads in amorphous thermoplastic materials, improving the strength and durability of the fastening.

They provide strong and stable mechanical connections, making them ideal for assemblies using metric screws that must maintain high performance even after repeated assembly and disassembly cycles.

Thanks to their design features, they are an effective solution for industrial applications where reliability, precision, and long service life of the threaded connection are essential.

The UHL threaded insert is completely symmetrical and has no collar. This configuration makes it easier to handle during automatic feeding in the insert moulding process, making it particularly suitable for highly automated production processes.

The HHL threaded insert, on the other hand, features a head (collar), which improves positioning during installation and helps increase torsional resistance once installed in the plastic component.

The choice between UHL and HHL therefore depends on the production process and the performance requirements of the application, such as the installation method, automation level, and mechanical stresses applied to the fastening.

UHL/HHL threaded inserts can be installed using two main methods: heat installation or direct insert moulding during the plastic component moulding process.

Heat installation involves heating the insert and then positioning it into the prepared hole in the plastic component. The heat locally melts the plastic, creating a stable anchoring area around the insert.

Insert moulding, on the other hand, allows the insert to be integrated directly during the component moulding phase, ensuring precise positioning and making it suitable for automated production processes.

The choice of installation method mainly depends on the type of plastic material, the production process used, and the performance requirements of the application.

A threaded insert is the ideal solution when a component must ensure high mechanical performance and long-term durability.

It is particularly suitable for applications subject to high loads, frequent assembly and disassembly operations, or when a more reliable connection is required compared with a thread formed directly in the plastic.

Thanks to its strong metal thread, the insert improves fastening stability, reduces the risk of wear in the plastic material, and helps maintain high performance even after numerous operating cycles.
