Wallace flexing machines test specially moulded rubber samples for resistance to cracking or cut growth by repeated flexing.

This digital gauge accurately measures the thickness of rubber and similar soft materials using a constant pressure anvil. The gauge conforms to international test standards and is widely used when testing rubber for tensile strength and compression set. The 150mm-diameter base provides a smooth flat ground surface upon which the test piece is placed. Location for a lower anvil, required by some standards, is also provided. The digital indicator is attached to an arm, which can slide on a vertical column.

Throughout the dial gauge travel (25mm), a constant force on the spindle ensures the anvil pressure on the test piece in constant.

A lifting lever attached to the indicator raises the spindle and upper anvil, allowing easy location of the test piece.

Accessories

Various diameter anvils can be screwed into the dial gauge spindle.

A range of additive weights can be placed in the carrier at the upper end of the spindle, which creates the correct anvil pressure on the test piece.

A software package is available which exports data from the indicator to a PC for further analysis.

The Dunlop Tripsometer measures the rebound resilience of a rubber test piece, which is defined as the ratio of returned energy to input energy when a ball strikes the test piece.

The apparatus consists of a pendulum in the form of steel disc, mounted on frictionless air bearings, with a striking ball (4mm dia.) attached to the disc periphery, 250mm from the centre.
The ball and its mounting bracket add an unbalanced mass of 60g to the disc.

An interchangeable test piece holder accepts an 8mm square rubber test piece or a 44.6mm dia Schopper disc, which is used with the vacuum pump (supplied as standard).

A scale and pointer indicate the angular displacement of the pendulum. An adjustable stop is attached to the scale allowing the pendulum position to be set before test.
An electrical mechanism releases the pendulum avoiding unwanted energy being imparted to the pendulum. The mechanism is easily removed to permit the free passage of the striker when required.

A Polished hardwood, draught proof cabinet is supplied, fitted with perspex panels and an access door.

Rubber Hardness Test Blocks are available in 5 scales - IRHD (Macro), IRHD (Micro), shore A, D and M. they are manufactured from high quality rubber formulated to resist the ageing effects on hardness of temperature and time. The test blocks are for use as a check to ensure instruments are functioning properly and read correctly. They are not intended as standards with specific hardness values.Test blocks should be returned to Wallace every 12 months for re-calibaration.

This robust, manually operated press cuts test samples from sheets of rubber and other soft materials with an exceptionally high force (41kN). Once prepared the samples are typically subjected to physical tests such as tensile, tear, dynamic, cure etc.

The press is operated with two hands. While one hand is used to lift the safety catch, the other pulls the handle which, through a lever system drives the ram down.

If the safety catch is not lifted, the ram cannot be moved ensuring operator safety.

The ram stroke is easily adjustable, ensuring that the die cuts through the sample but is not itself compressed, preventing damage to the cutting edge. But as a further precaution the operator is advised to place a suitable backing material on the cutting table to protect the very sharp edges of the cutter.

Articulated stainless steel fingers, mounted off the press frame, are adjusted to pass through the holes in the cutter back-plate so that the sample is automatically ejected on the return stroke of the ram.

The cutting table is 150mm wide by 200mm deep and cutters must not exceed these dimensions.

Accessories

A large range of cutting dies, conforming to international standards, is available for use with the S1 Specimen Cutting Press.

A large range of cutting dies, conforming to international standards, is available for use with the S1 Specimen Cutting Press. Each die is fitted with a safety back plate. a shank can be fitted to each cutting die, acting as the interface for locking the die into the ram of the press.Dumb-bell, circular and parallel blade cutters are available as well as angle, crescent and trouser tear cutters.

We also supply cutters to our customer's own design and offer a cutter reconditioning and sharpening service.
