13.2 billion Aerosols are sold around the World every year and Avon Group’s Maerdy facility is one of only two companies that make them.

Material Design and Development

At Avon Engineered Rubber, our in-house chemists and polymer technicians design and develop compound to ensure that all our materials are compliant with evolving legislation and meet any application specific requirements from our customers. New raw materials are continually being assessed, providing customers with the opportunity to explore lower cost options.

All our Rubber compounds are mixed using the latest mixing equipment with industry leading quality control systems and processes. Further testing is conducted on all mixed batches to ensure mix consistency and specification adherence prior to manufacture. We are able to guarantee full traceability to our customers.

The materials we process include Nitrile, Chloralrene, EPDM, Butyl and Chlorobutyl, Silicon and Fluorocarbons.

Aerosol Gaskets and Seals

AER supplies Gaskets and Seals to Worldwide Aerosol valve, atomiser spray and pump manufacturers. Our Gaskets are used in the widest spectrum of applications which include Health and Beauty, Household, Medical finishing and many other markets.

Extruded and Cut Seals and Gaskets (Cup Seals)

The tubes we use in our Cup Seals are manufactured by either, a closely toleranced extrude-and-cure process, or by Injection Moulding on state of the art Rubber Injection presses. The tubes are then cut to exacting tolerances on the very latest design of high speed Lathe cutting machines. Typically an AER cut Gasket is accurate to within 001″ – 003″.

Both during and post manufacture, our Gaskets are subject to rigorous quality control and inspection regimes utilising numeric SPC systems and digital inspection mediums.

Pressed Stem Seals and Gaskets

Our Stem Seals are manufactured to the same exacting standards as our Rubber Cup Gaskets, utilising application specific, industry compliant, raw material.

Raw material is converted into tightly toleranced roll format before being presented to our ultra high speed cutting presses.

Avon Group have developed and evolved tooling that provides a double compound cut which delivers the most accurate and highest quality pressed Seals thus eliminating waste.

Our control procedures are such that we typically manufacture Gaskets with a tolerance of 002″.

All AER Gaskets go through a post manufacture and in-process inspection as well as a final quality inspection and audit prior to packing and distribution.

Technical 3D Rubber Mouldings

Avon Group have invested extensively in the most modern high speed energy efficient Rubber moulding presses and sub processes.

Our Moulding capability includes mono material Moulding, Rubber over moulding and Rubber to Metal bonding.

AER supplies high quality technical Mouldings and Assemblies to the Automotive, Aerospace, Marine, Truck and Bus, off Highway and Industrial market sectors.

We are accredited to TS16949 and many customer specific audit processes.
