 — Several different size copper-crusher cylinders are used to measure pressure depending on the pressure range of the cartridge. A small-diameter cylinder is used for lower-pressure pistol cartridges because it will deform more and provide better pressure resolution at lower pressures.

evaluate the characteristics of copper cylinders required to properly specify the copper cylinder design used on the M4 carbine, M16 rifle, and M249 squad automatic weapon (SAW) for measurement of firing pin indent energy.

Copper Crusher Cylinders. DELTIMA Precision started its own development and production of equipment for ammunition quality assurance. We are open for customized or OEM production.

 — This specification covers copper crusher spheres for use in crusher gauges, primarily intended for use in measuring pressures in weapons.

Copper Crusher Cylinders are used for powder gases pressure measurement during shooting. Principle of pressure measuring is evaluation of crusher cylinder's deformation after shot. The length of crusher cylinder must be measured before shot and after shot. The difference is proportional to pressure.

 — Single-cylinder hydraulic cone crusher: Suitable for medium crushing, processing harder ores, with a large crushing ratio. Multi-cylinder hydraulic cone crusher: Used for fine crushing, with the characteristics of high efficiency and energy saving.

The copper crusher measures firing-pin load pressure using a solid bar machined of high-purity copper, from which the mini copper bars are sliced and machined to the exact size and shape of the many rimfire cartridge designs (e.g., short, long rifle, magnum).

Copper crusher cylinders are produced according to strict requirements on precision and material purity. Own machining capability, heat treatment and polishing alow part customisation.
