Expert Capabilities
Our quality commitment begins with materials and processes used to manufacture our products. Major capital investments are made to ensure process capabilities. We continue to invest in our foundry operation. We utilize computer controlled, automated molding equipment that allows for “quick change” of patterns which enables us to do short runs as well as long runs of cast copper and aluminum products, providing the same high degree of quality and process repeatability with no delay.
Mastery of cold-forming (extruding, upsetting, coining and piercing) technology allows Penn-Union to produce dimensionally consistent, high-strength products such as copper split bolts, copper press-ons and silicon bronze hardware, to name a few.
Our in-house machine & tool design expertise allow us to quickly introduce specialty production equipment, which combines a number of manufacturing operations to improve productivity and product quality. Penn-Union utilizes computer controlled machine centers.
