SPIROL has introduced a new, high performance series of moulded-in inserts for plastics assemblies, consisting of multiple bands of helical knurls to maximise torque resistance, balanced with radial undercuts to achieve high pull out (tensile) force.
These moulded-in inserts are designed to be placed in the mould cavity prior to plastic injection and, SPIROL says, offer exceptional performance due to unrestricted plastic flow into the retention features on the outside diameter of the inserts.
These lightweight, lead-free threaded inserts are manufactured from 2024 grade aluminium, which provides the best combination of strength, corrosion resistance, machinability and cost. SPIROL states the Series 63 and Series 65 inserts are 40% stronger than brass, and ⅓ the weight of the same insert manufactured from brass. Standard metric thread sizes include M4, M5, M6, and M8, and standard inch threaded sizes include 8mm – 32mm and 10mm – 24mm.
SPIROL offers a comprehensive line of inserts for plastics including press-in, self-tapping, heat/ultrasonic and moulded-in styles to accommodate specific performance and installation requirements. SPIROL’s application engineers can also be involved in the design stage and will not only recommend the most cost-effective threaded insert for plastic assembly, but can also help make critical design recommendations between the engineered fastener and an assembly.
