Key products for plastics – Zerts inserts:

• Self-tapping inserts – equipped with cutting slots or holes that allow them to cut their own thread when screwed into a prepared hole. They provide high pull-out resistance and are used in thermoset plastics and glass fibre reinforced plastics.
• Heat-staking and ultrasonic inserts – the SHZ series and other inserts with helical knurling, which form a durable bond with the part after the surrounding plastic is locally melted. They are suitable for thin-walled housings.
• Molded-in inserts – placed directly in the mould before the injection moulding process. Available in through-hole (MTZ) and blind (MBZ) versions; the blind version prevents plastic from flowing into the thread.
• Press-in and expansion inserts – solutions for cold installation in soft and rigid plastics, enabling a fast production process without the need for additional heating equipment.

The company also offers:

• design support – access to 2D and 3D documentation and advice on selecting the insert geometry for a specific polymer
• logistics – a global distribution network that ensures continuity of supply
