Lock Bolt
Benefit: Cost Saving
Main Forming Process: Conventional Processing
End Use Sector: Security
Material: Ferrous


The part is an outstanding example of conventional PM lock hardware technology, stepping into the design realm of MIM technology. This highly sophisticated and complex tool design combines 9 levels of dimensional changes by using a combination of multiple punches synchronising with die shelves.

The component fully designed by ASCO is produced in Copper Infiltrated Steel and then finished with Electro Nickel plating, as per ASTM B633. This part replaces a 2 piece assembly, saving approximately 50% of the original cost when compared to traditional manufacturing processes.

Statistical controls are applied throughout the compacting and sintering processes to provide extensive powder transfer and fill compensations, resulting in even density distribution within all cross sections of the component.

ASCO also produces various types of Deadbolts and Latch bolts within the Residential and Commercial hardware sector, supplying onto major door lock companies for over 50 years. All of our design solutions are governed by a qualification through the BHMA Cycle Testing standards for functional strength, security, finish and corrosion requirements.
