Custom rubber compound products developed to satisfy specific customer requirements and maintain the integrity of existing compounds.

Material Development Laboratory

The Airex Rubber Products Research and Development Laboratory performs chemical and physical testing to ensure that all products meet or exceed our customer’s specifications. Airex currently offers a broad spectrum of compounded elastomers designed for maximum performance and maintains a formulary of hundreds of proprietary compounds, each specifically designed to meet the needs of our customers and the markets they serve. In cases where no specification exists or unique material requirements need to be met, we have the expertise to custom formulate new compounds to meet these situations.

Most applications can be satisfied from our extensive existing material compounds. Custom rubber compounds can be developed to satisfy your specific requirements. Please inquire about your specific applications.

The laboratory is under the direct control of our Chemist.

Complete in-house control over construction of elastomer mold tooling and fixtures used in conjunction with rubber masking products.

Machine Tool Division

Elastomer mold tooling manufactured using CNC, 3D printing, Manual and Waterjet technologies.

The Airex Tooling Division is capable of handling a large range of machining requirements, including molded parts up to approximately 40″ in diameter and fixtures up to 48″ in diameter.

Our mold makers/toolmakers are proficient with the design and manufacturing of single and multi-cavity molds. They are experienced in prototype, short and long-run production, and the manufacturing and use of jigs, fixtures, gages and dies.

Our toolmakers are adept in working with various materials, i.e. plastics, aluminum, aluminum alloys, brass, bronze, steel, steel alloys, tool steels, and stainless.

Our expertise enables us, as required, to design our molds to accept a customer’s metallic part in either a semifinished cast state or a fully machined state, allowing a superior rubber-to-metal hot bonded assembly.

A full complement of turning, milling, and general machining equipment, both C.N.C. and manual are housed in our on-site tooling division. This state-of-the-art equipment, combined with the expertise of our mold makers and product design engineers, enables us to meet customer requirements. We continually strive to expand our capabilities to meet existing, as well as new customer needs.

Our Production Division is capable of molding rubber products using a wide range of steam and electric, as well as extrusion and die cutting presses.

Production Division

Our Production Division is capable of molding rubber products using a wide range of steam and electric presses as well as extrusion and die cutting presses.

Elastomers used in the production of specific parts are milled in-house to the specifications and formulas determined by our Chemist. The molders work to exact specifications dictated by our customer requirements as well as mold size and material characteristics. At Airex, we manufacture using a quality management system based on AS9100 and ISO9001.

The following is a list, by no means comprehensive, of precision molded masking materials commonly used for surface treatment operations. Click here for a more detailed Materials list.

Preban 3, 5, and A-9666 are premium materials designed for the high temperature and abrasion resistance of thermal sprayed coatings.

  • Preban M was developed to meet the strict requirement for processing of orthopedic implants through thermal spray coating operations.
  • A-9560 is designed for extruded materials used for high temperature and abrasion resistance.
  • A-6040 provides excellent resistance to vibratory finishing and wet media abrasion operations.
  • A-7703 was developed for maximum dry abrasion resistance of shot, glass or grit blast operations.
  • A-3688 or A-2620 and A-8770 are just a few of our chemical and acid-resistant materials used for plating and commercial solvent applications.
  • A-1550 material is excellent for airflow/Waterflow fixture masking. Core plugs, edge protectors, and any application where elongation and compression resistance
