SI® threaded metal inserts for plastic materials
22 April 2016
SI® threaded inserts from PennEngineering® provide durable and reusable metal threads in plastic materials. Creating a joining point for mating hardware and allowing for access to an assembly whenever required.
Unlike fixed and unyielding joining methods, such as adhesives or rivets, the inserts ultimately offer the capability to disassemble and reattach plastic components easily and quickly – without damaging the threads, compromising attachment integrity, or otherwise adversely impacting an assembly. Brass, stainless steel and aluminium types are available as standard.
Applications for SI® threaded inserts include consumer electronics (wearables, smart phones, and handheld devices) and plastic equipment or components for the medical, automotive, aerospace, transportation, and recreational industries, among many others.
The product line includes ultrasonic/heat staking inserts for installation ultrasonically or with a thermal press; moulded in types installed during the moulding process; and press-in types installed by pressing the insert into a pre-moulded or drilled hole. All install permanently in the plastic material.
SI threaded inserts have been engineered in a variety of designs and lengths – including micro fastener versions with threads as small as M1 – and can be supplied in unified or metric thread sizes.
