Threaded insert for plastics, insert moulding (UFTC)

The UFTC blind brass threaded insert is a technical solution used in plastic moulding processes to create strong and reliable metal fastening points directly integrated into plastic components. This type of insert is particularly suitable when the plastic material alone cannot provide the mechanical performance required for a durable threaded connection.

UFTC brass threaded inserts with a blind end for plastic components are designed for integration through the plastic insert moulding process, becoming permanently incorporated into the component during injection moulding or other plastic forming processes. This solution improves assembly reliability and ensures consistent performance even in applications subjected to repeated assembly and disassembly cycles.

The main feature of the UFTC blind threaded insert for plastic is its closed-end configuration. This design is particularly suitable for applications where a through-hole solution is not required or where the opposite side of the component must remain closed. The blind end design also supports controlled integration during the plastic moulding process, contributing to the quality and reliability of the final component.

The UFTC threaded insert features a specific external geometry consisting of three opposed helical knurled sections and additional grooves, designed to improve anchoring inside the plastic material. This configuration allows a more balanced distribution of mechanical stresses, increasing pull-out resistance and torque resistance while reducing the risk of insert rotation during operation.

The selection of the correct threaded insert for plastic insert moulding depends on several technical factors, including the type of plastic material used, component geometry, manufacturing process, thread size and required mechanical performance. A proper evaluation helps identify the most suitable solution and optimise the reliability of the fastening system.

Blind brass threaded inserts for plastic materials are used in many industrial sectors, including automotive, electronics, electrical equipment, industrial automation, industrial machinery, household appliances and technical plastic components. They are particularly suitable whenever a permanent metal thread needs to be integrated into a plastic part, ensuring precision, strength and repeatable assembly performance.

The use of brass as the insert material provides important technical advantages, including good corrosion resistance, excellent machinability and suitable thermal conductivity. These characteristics make brass threaded inserts suitable for industrial and electronic applications where long-term reliability and stability are required.
