PTI Tech announces over one million MIM tungsten setback pins milestone

PTI Tech, headquartered in Clifton, New Jersey, USA, has now delivered over one million tungsten MIM components to Action Manufacturing Corp, a manufacturer of fuzes based in Bristol, Pennsylvania, USA. Leveraging its Metal Injection Moulding technology, PTI Tech manufactures the high-precision tungsten setback pins used in the M739A1 Point Detonating Fuze on the M107 and M795 155 mm artillery rounds.

PTI Tech was originally contacted by Action Manufacturing Corp to assist with a production issue they were experiencing with a vendor of tungsten components. Tungsten is a high-value material that is very difficult to work with via conventional manufacturing methods (such as subtractive machining methods) and impossible via other methods like investment casting. The vendor, employing press and sinter tungsten manufacturing, was reported to be having difficulty hitting shipment deadlines, as well as delivering high levels of non-conforming parts that required visual inspection and sorting.

PTI Tech utilised its MIM technology and advanced multi-cavity mould tooling to manufacture the tungsten setback pin net-shape, maintaining tight tolerances and providing high throughput. With MIM, tungsten and other refractory metals are moulded net-shape, then de-bound and sintered.

In addition to MIM, PTI Tech has worked to advance polymer and ceramic injection moulding capabilities, supporting the aerospace, medical, defence, and industrial sectors for over thirty years.
