What is a Back up Pad?

It’s a support for abradants which is mounted onto the pneumatic or electric orbital sander and is generally composed of a part in plastic, a part in rubber and a specially designed surface for the attachment of the abrasive disc using a self-stick or Velcro® system.

The Twister back up pad is the result of Abrex-System’s twenty years of experience in the flexible abradants sector applied to bodywork, production and car repair, nautical, aeronautic and timber trades. It’s covered by an international patent EP1186379. It has been designed and produced in the Abrex-System machine shops with the aim of improving the basic results of sanding using pneumatic orbital sanders.

This pioneering technology prevents bottlenecks in the flow of dust during aspiration by channelling it directly through the “chamber”. The system means that the speed and volume of the air being sucked in can be increased, with the consequent following advantages:

1. continual cooling of the surface being sanded and of the abradant itself, thus prolonging its life by 30% according to laboratory tests.

2. improved removal of dust from the work surface and the air, thus improving the health of the operator and the quality of the work.

Thanks to its special composition, it’s possible to produce all the standard perforations: 7, 9 holes and other innovative perforations such as: 21 holes, 75 holes and other mapping, exclusively customised to the client’s design  (MULTIHOLE) without infringing on the planarity of the back up pad itself.

The Twister pad has been designed and produced in the      Abrex-System S.r.l. machine shops using the best materials, able to give the final product the right  requisites for vibration-free sanding.

A determining role in all this is played by our production plants with specially built machinery and a control system which enables constant checking throughout the production cycle, to obtain a final product with an extremely high quality standard.

This utensil also falls within the recommended weight parameters of the most import orbital sander manufacturers.

This presentation gives an idea of its many features such as the ability to customise the plastic part, the range of perforations available and the materials used which. All together make it a unique, exclusive product destined to become a benchmark on the international market.

> High quality plastics, chosen according to their specific characteristics of weight, stability and mechanical resistance. Possibility of customising the product in various colours.

> As well as the colour , customising may also take the form of applying labels showing pictograms, in other words the obligatory safety measures to be adopted during sanding, the maximum speed to be used with the tool and any company logos.
Creation of customised boxes.

> Adaptors and screw are also provided to enable attachment to all types of currently available sanders.
Version with universal threading: with burnished screws 5/16” UNF and washers.
FESTO® version: with galvanised screw M8 and adaptor.

> The rubber part supporting the abradant may be:
- Extra hard (BLUE) for rough grinding with hard grains.
- Medium hard (BLACK) for sanding with medium grains.
- Soft (WHITE) for sanding with fine grains.

Attachment systems of the abrasive disc:
> Velcro® system (standard production)
> Self-adhesive system (on request)

> Soft interfaces. With the simple addition of a soft interface the back up pad can be easily transformed for sanding with fine grain.
It’s an immediate and economical solution.
Available in 2 thicknesses 10 and 5 mm.
