Stampings - Metal (0.001" - 0.010")

Microminiature, miniature and medium-size parts (pin head size to several inches in diameter) can be stamped in runs from 10,000 to millions/month. Presses rated at 30 tons and 75 tons are used to stamp parts to tolerances within 0.001". Continuous strip or bulk quantities of stock are used. Maximum widths of 8" can be handled. Lengths are controlled by the die size.

Carbide dies are used extensively for up to 1800 spm runs. Several million hits between sharpening are possible. These tools are generated by wire EDM machines with high speed and accuracy to 50 millionths of an inch. An in-house tool-building capability is important.

Prototypes and short runs from 1 to 2,000 parts can be made to test new stamping designs. Aluminum, brass, bronze, copper, Inconel, magnesium, steel, stainless steel and titanium metals in thicknesses from 0.003" to 0.040" can be accommodated. Stamping, punching, nibbling, embossing, bending and contouring operations are applied. One specialty is thin slotting and pierce slotting to less than one-half the material thickness.

Metal stampings are used in electronic computers, cameras, calculators, appliances, copying machines, telecommunication equipment, automobiles and missiles.

Because of their sensitive applications, stamped metal parts must be produced in a quality control environment. Statistical Process Control (SPC) is one of the quality methods employed. In addition to an in-place quality-control method, attention to continuous improvement in the company's approach to problem solving, products and services is an essential element of providing close-tolerance stamping. An ISO Registration is an asset to a vendor's credentials.
