SPIROL has introduced a new range of 2024 aluminum Press-In Threaded Inserts, available in symmetrical (Series INS 50) and headed (INS 51) versions.
These new aluminum Inserts expand SPIROL’s existing line of Press-In brass Inserts and are designed for use in plastic assemblies across a range of industries.
Electric vehicles (EVs) increasingly rely on plastic components to reduce weight and improve efficiency. Threaded Inserts play a key role in these assemblies by reinforcing plastic parts and providing durable, reusable metal threads for fastening.
Unlike screws threaded directly into the plastic, which can degrade over time due to material creep, Press-In Inserts maintain long-term joint integrity under mechanical stress, vibration, and thermal cycling — conditions commonly found in EV environments.
SPIROL’s aluminum Press-In Inserts are designed for installation without heat and are intended to offer a cost-effective solution for applications where acceptable joint performance is sufficient. Both the INS 50 and INS 51 series are suitable for applications requiring reduced weight, as 2024 aluminum is approximately one-third the weight of brass.
Additionally, 2024 aluminum is lead-free, aligning with current environmental and safety regulations.
Material choice can significantly affect both the function and cost of an assembly. While brass remains a standard for machinability, 2024 aluminum provides lightweight performance and unique galvanic properties, offering engineers additional flexibility in material selection.
SPIROL offers a variety of Insert options tailored for different performance and installation needs. The company’s engineering team provides application-specific guidance to support the selection of appropriate Inserts for each design.
