Powder metallurgy is the process of blending fine powdered materials, pressing them into a desired shape or form (compacting), and then heating the compressed material in a controlled atmosphere to bond the material (sintering) and forming both simple and highly complex component parts such as sheaves, pulleys and high strength gears. Once an appropriate material is selected from a variety of pressed metals, we will compact the metal into the appropriate shape using presses that exert tons of pressure.
These "green" pieces have the accurate shape but are still very brittle during this part of the process. Then we will permanently harden the powders by sintering the metal to a temperature just below its melting point. This process, known as sintering, ensures that the part will retain its shape. We undertake the sintering process in furnaces that reach extremely high temperatures within a protective atmosphere that allows for the metallurgical bonding of the metal particles without altering the shape of the part.
Unlike other metal parts manufacturing methods, powdered metal parts often require no secondary operations once they have completed the sintering process. We can perform any number of optional secondary processes either in-house or at a number of excellent local vendors including heat treating, tempering, steam treating, machining, drilling, tapping, grinding, honing, boring, lapping, plating, coating, painting, inspection including visual, NDT, and resonance, oil and resin impregnation, as well as assembly operations. These operations can increase the strength, resistance, or lubrication of the powdered metal part.
We are a fully-diversified organization serving automotive, medical, electrical, pump, appliance, and lock industries. Our largest niche is the production of stainless steel components for automotive, architectural hardware, locks, and pump industries. Stainless production represents more than 40% of the company's sales. We also specialize in the compression limiters used by plastic molders. Examples are: housings; impellor inserts; and bearings all made from stainless powdered metal or plated iron materials.
Redline Manufacturing Consultants provides our customers with superior value. Our overhead is kept low without compromising quality, technical support, or customer service. We do not have to support a large corporate staff. Our managing partners are the owners. We are ISO 9001:2008 certified and certified to the TS-16949 standard as well.
