AMT specializes in engineering-grade nylons and acetals and uses state-of-the-art technology to design and deliver specialized injection molding solutions for an assortment of applications. Meeting ISO and aerospace specifications, our superior molding technology can be employed on virtually any size solution from miniature parts to large, multi-component products. AMT combines plastic resins with a variety of metal stampings, filters, machined metal parts, gaskets, threaded inserts, and other components to meet our customers’ unique specifications.

AMT offers a wide selection of injection molded materials from acetal and nylon to polyester:

  • PA6 and PA6/6: Polyamide (Nylons) Filled and Unfilled up to 60% GF (Minlon)
  • PBT: Polyesters Filled and Unfilled
  • PPA: Polyphthalamide (Amodel)
  • PPS: Filled and unfilled (Ryton)
  • TPE: Thermoplastic Elastomer (Sanoprene)
  • HDPE: High Density Polyethylene Filled and Unfilled
  • POM: Acetal Polyoxymethylene Filled and Unfilled Multiple Grades (Delrin)
  • PEEK: Polyetheretherketone

Kelco Industries will help you find the best engineered industrial components for your industry product line or design customized parts for your specific needs.

All components are 100% American made with global distribution.

Horizontal Presses

Meeting ISO 0001, AS9100D, IATF 16949, and ISO1 14001 specifications, our superior molding technology can be employed on insert molded and miniature parts as well as large, multi-component parts to consistently serve the needs of a wide range of industries including construction, maritime, medical, aerospace, automotive, and communications.

Our commitment is to work closely with our customers to support the design and development of their products and to create robust parts and processes.

We are dedicated to supporting our customers’ projects beginning with the concept through design, material selection, mold fabrication, and the final molded product. A wide range of material choices are available from acetal and nylon to polyester and engineering grade nylons. We also support our customers with product re-engineering to improve efficiency through superior manufacturing.

All of our products are manufactured in a climate-controlled metrology lab with CMM & OGP. Our in-house Mold Tool Maintenance Department with dedicated mold makers ensures consistent quality and service for every customer.

Case Study

All of these electrical sensors were constructed using Rynite 530 (PET). Meeting a (±) 1° angular tolerance, a .5° draft per side, and a true position of .01 inches on all diameters, these sensors were built to match client specifications supplied to us through two-dimensional CAD drawings. Each sensor measures .768 inches in width and 1.16 inches in overall length.
