There are many products in use today for whcih spare components are no longer available. In some instances equivalent products might be available but in many instances, the original product is simply not available although the design perfectly suits the application. Where parts of the product have value but for example where rubber elements have failed though fatigue for example, then it is worth considering refurbishment to retain the value in sound metal parts.
To complement the manufacture of track pads, AVMR have recently undertaken the refurbishment of 400 pads as pictured below in various stages from as received to the final remoulded track pad. These pads have an aluminium backing plate which is very badly corroded by contact with sea water, but it is still more economic to refurbish these than to manufacture from new, with new castings.
The process employed by AVMR includes the cryogenic treatment of the pads to remove 99% of the rubber from the surface. This is followed by an aggressive grit blasting process to remove surface corrosion and other traces of old rubber.
Prior to re-moulding, the pads are subjected to hot vapour degreasing and then the chemical bonding agents are applied by spray.
The actual rubber bonding/moulding is carried out in a new 4 cavity mould tool. The rubber used in this instance is from our range of military materials (MVEE specs.)
AVMR will be happy to quote for new production or refurbishment of existing products of a similar type and can design mould tooling in-house for such products up to 600mm long. Materials used can be any from our extensive existing range which includes natural rubbers between 35 and 90ShA, or from a range of Neoprene, Nitrile or EPDM materials. see rubber colour codes/specifications in Technical>Rubber Materials & Properties.
Bonding of rubber materials, particularly to metallic substrates remains a speciality of AVMR Providing isolation solutions utilising a wide range of materials and techniques remains a core strength of the business for its vibration and shock mitigation sector.
