    onsep Manufacturing About Us

    Since 1982 Konsep Company, a division of Allegheny York, has been molding thermoplastic and engineering grade materials including glass and mineral-filled. We utilize 5 injection presses with a scope of 85 to 400 ton to do both short and long runs. Konsep Company also produces compression molding with 12 presses ranging from 250 to 2500 ton to mold NBR, Viton, Duck & Rubber and other compounds.

    Konsep Company readily manufactures wipers, seals, backup rings, bearings and guide rings to meet your demands utilizing advanced rapid prototyping technology. Parts can be made from over 100 profiles for same-day delivery using our extensive inventory of available materials.

    Time to market should be a critical consideration in your selection process. Our in-house design staff is here to help evaluate your design and material needs. Minor changes in an existing mold design can also dramatically reduce tooling costs, improve part yield, and speed production cycles.

    The largest single cost in the set-up of a production run is the tooling cost. Often manufacturers outsource tooling stage which dramatically impacts the end cost. Our in-house CAD/CAM system, mills, lathes and brand new Bridgeport® Auto-Tool CNC Machining Center affords us the ability to provide in house tooling to save our customers time and money!

    Providing a high quality component congruent with our customer's requirements that is received punctually and satisfactorily are paramount for Konsep. You may rest assured, from start to finish, our in-house design, tooling and state of the art production will meet or exceed your expectations. Tight tolerances, tricky configurations and exotic materials are welcomed by our team. At Konsep Company, we take pride on our ability to take on your most challenging production issues and give you a product we'll both be proud of.
