    Your Complete Metals Stamping Source

    Olin Brass Fabricated Products is a precision stamper of copper based alloys, stainless steels, aluminum alloys, carbon steels and clad materials serving a variety of end use markets. Our products include everything from parts for demanding automotive applications and surface critical decorative plumbing fixtures, to power distribution and electronic components.

    With over 80 years of experience utilizing proven stamping techniques, we are uniquely equipped to deliver cost-effective components of the highest quality to our customers. These capabilities are enhanced by our location on the same site as Olin Brass’s primary strip mill in East Alton, giving us the benefit of vertical supply chain integration with copper components at the source.

    Production Overview

    Olin Brass Fabricated Products is uniquely positioned to utilize the most cost effective stamping processes for a given application, based on annual usage, complexity, base material and other factors.

    We design and run tools on over 40 presses, including progressive, transfer and multislide technologies. Components are produced with the use of tailored gaging for quality control and supported by ISO and TS certified procedures. Regardless of whether the product life is 5 years or 25 years, as long as the part is active we will maintain the tooling for the full life of the program.

    While our primary service is to customers who have a finalized stamped part design, we can and do collaborate on redesigns in order to improve metal efficiency and production rate. This has resulted in some conversions from screw machine parts and tube products into stampings. Whether your needs call for our specialized knowledge and abilities to form parts from copper alloys, or for stamping stainless steel, aluminum, cold rolled steel, or another material, contact us now to learn how we can support all of your stamping needs.

    Stamping Technologies

    Olin Brass Fabricated Products is unique in that we design tools and manufacture products utilizing three distinct metal stamping technologies: progressive, transfer, and multislide.

    Progressive Press

    In a Progressive Press, the metal strip will carry the part through the tooling. Progressive dies provide flexibility due to their construction, which makes them interchangeable among many presses, given sufficient tonnage and bed size. To further enhance cost effectiveness, we will design multiple cavity tooling to maximize production efficiency for higher volume applications.

    Our progressive presses range in size from 60T to 800T. We will design to build according to your specifications, or accept any existing tooling that you currently own.

    Transfer Press

    In a transfer press operation, mechanical “fingers” grip each part and move it through the tools. This transfer slide will automatically index the parts to the next station with each stroke of the press.

    Olin Brass Fabricated Products has a wide range of transfer presses to accommodate a variety of product sizes. This allows us to design complex parts that may require up to twelve stations or deep draw up to a six-inches in length.

    Multislide Press

    A multiside press can be utilized in operations where the edge of the input strip doubles as an edge of the part being fabricated. It offers greatly enhanced cost-effectiveness by minimizing the amount of scrap produced, and by allowing the use of lower cost tooling on less complex parts.

    Engineering and Q.A. Services

    Engineering at Olin Brass Fabricated Products is handled by a team of professionals whose depth of experience allows us to take on the most challenging stamping projects in terms of design complexity and premium surface critical applications. Their services represent an extraordinary value; after a one-time charge for the initial tool build, it is our policy to fully maintain the tools at our cost for the life of the product.

    Calibration and Inspections

    Gaging methods and equipment are tailored to each specific part design and key characteristics dictated by customer requirements. A thorough calibration system verifies all gages are calibrated on a yearly basis, with more frequent inspections for any signs of wear or damage. Primary inspection of product at the press by the operator emphasizes our commitment of building quality into our parts. Control plans detail the in-process inspection requirements and are part of the PPAP submittal process used for initial samples.

    Metallurgical Support

    One of the unique services offered by Fabricated Products is metallurgical support, especially relating to copper based alloys. Working with the customer’s design engineering team, we build around the most critical functional and material requirements of the application. We have access to the material data generated by Olin Brass in order to suggest alloy and temper options that will best serve the end use and insure manufacturability of the part.

    ISO and TS Certification

    Olin Brass Fabricated Products is certified to the latest ISO 9001:2015 standards. Further, we are committed to staying current with all new trends in tool design, inspection equipment and methods.
