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.

Vertical Presses

AMT manufactures electrical connectors for automotive and construction industry clients worldwide. Our custom-built products are equipped with a variety of features, including an allowable leak rate of 10 cc per minute at 8.5 PSI, an O-ring groove with a .003 inch maximum allowable parting line mismatch, 20 pound capacity load on terminals, and a part identification number molded within each sensor.

AMT uses a wide variety of plastic resins and combines them with a range of metal stampings, filters, machined metal parts, gaskets, threaded inserts, and other metal components to create value-added products. Our high quality, cost-effective solutions offer efficiency and consistency throughout all AMT products.


Advanced Molding Technologies uses state of the art automation for high volume production to maintain the most cost-effective molding solutions for our customers. This also enables us to meet stringent production schedules and exceed quality goals both internally and externally.

Regardless of the size or type of component you need, AMT will design a production strategy to exceed your needs.

Part & Tool Design

We offer Part Design assistance with DFM advice, prototypes via 3D prints, prototype tooling, and fixture design. We also have 3D CAD capabilities with Autodesk inventor and a Stratasys Fortus 400 mc (FDM) 3D printer on-site for prototyping.

We offer Mold Tool Design assistance and specialize in import mold tooling maintenance and procurement as a service for our injection molding customers.

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.
