Threaded insert HiMould®

The Tappex HiMould® range of brass thread inserts has been designed as a technical advancement on traditional inserts, with direct push-fitment on top of close-toleranced pins, located within the cavity of a customer’s mould tool. Traditionally, thread inserts were located by screwing onto these pins but the Tappex HiMould® simply requires to be pushed onto plain pins for increased speed thus saving time and yet whilst maintaining accuracy. With the HiMould® range of inserts, this costly and inefficient process becomes unnecessary, as the thread insert can be rapidly located on to plain pins thus giving higher productivity and reducing tool down time. Despite the use of plain pins, the unique design of the HiMould insert, still gives generally ‘flash free’ threads. Moulding-in for Thermoplastic and Thermoset materials Tappex HiMould® inserts have become widely used for most types of thermoplastic and thermoset plastics as they are suitable for both injection and compression moulding processes. HiMould® range ‘generic’ insert features: Easier moulding – ejection because the HiMould® insert is located on a plain pin; there are no secondary operations required before removal of the moulding from the mould tool. This allows the use of sleeve ejectors or a centralised ejection screw; in turn this significantly simplifies tool design and produces easier moulding injection during production, thereby increasing productivity. Recessed – The HiMould® insert can be used in preference to post-mould installed inserts where the application of the insert is in a deep recess or cavity.
