Info
Post moulded inserts can offer significant benefits over mould-in inserts such as a reduction of in place cost, no secondary operation to clean flash residue from threads, fewer rejects due to dislodged inserts and ease of installation. Press-In Inserts for thermoplastics are available in a range of thread sizes, in headed and non-headed variants, are manufactured from brass and stainless steel and are suitable for installation in soft, medium and hard thermoplastics by simply pressing in to a pre-prepared hole. Featuring a free running thread, the sharp radial knurl provides good torque-to-turn resistance while the fins lock into the hole wall during installation providing good pull- out performance.
