Foam Constant Load Pounding Machine

Model: F0021

The Constant Load Pounding Machine is used for the determination of loss in thickness and loss in the hardness of flexible cellular materials intended for use in upholstery. This test provides a means of assessing the service performance of flexible cellular materials of the latex and polyurethane types used in load-bearing upholstery. The test can be performed on both standard size test pieces cut from stock material and to shaped components.

Foam Porosity Tester

Model: F0031

The Auto FPT is used for monitoring the porosity of flexible cellular polyurethane. The machine determines how easy air passes through a cellular structure. Airflow values may be used as an indirect measurement of certain cell structure characteristics. A test piece is placed in a vacuum chamber cavity and a specified automatic constant differential air pressure is applied.

Seam Fatigue Tester

Model: S0014

This Seam Fatigue Tester was designed to test the strength of a sewn seam in a fabric, such as in-vehicle seating covers. It operates by lifting a 3kg weight using the sewn fabric as a ‘tow rope’. The 3kg mass is dropped onto a shelf at the end of each stroke and lifted again by the fabric. The shelf height is adjustable so that the mass can be set down gently without too much jerk. The machine is double-ended and two sets of specimens can be tested at each end.

Stiffness of Cloth Tester

Model: CellFlo

CellFlo is a pocket-sized digital instrument, ergonomically designed with soft grip edges for hand-held comfort. With a digital air flow reading of 0-100 (zero to 100% flow), the unit allows safe monitoring of foam quality at the production line cut-off. This can also assist in necessary production adjustments during the run.

Foam Resilience Tester

Model: F0030

The Foam Resilience Tester has been manufactured to determine the resilience of flexible cellular polyurethane. A steel ball is dropped vertically onto a test piece and the rebound height is measured and expressed as a percentage of the height dropped.

The machine consists of a 79.5 ± 1kg platen with a maximum load of 250kg which is used to drop down from specified heights. The machine operates both manually or automatically using an external PC linked to the computer.

Mattress Rollator & Durability Tester

Model: M0015

The Mattress Rollator consists of a weighted roller which moves width ways across a test mattress to simulate body movement. The length of stroke to which the Roller moves is very easily adjusted, by sliding the stroke adjustors left or right, to suit the relevant mattress under test. Unloading and loading of the Roller onto the test mattress are done easily via a motor-driven lifting assembly. Options with this machine include with or without safety light curtain and compression testing function.

Clicker Press – Test Sample Preparation

Model: C0056 Series

The Swing Arm Clicker Presses are used for a wide variety of die-cutting applications. The most common uses are cutting soft to semi-rigid materials such as gaskets, leather, cork, rubber, elastic, foam, and other like materials. The SE 25 is completely hydraulic and is made of strong casting material to ensure powerful yet quiet running.

Cornell Type Tester

Model: C0044

Designed for testing and evaluating Innerspring and Boxspring mattresses. There are several different methods used for this type of evaluation; measurements regarding firmness, firmness retention, durability, the effect of impact etc. The Cornell Type Teser is used to test the long term capacity of bedding to resist cyclic loading. The machine consists of a double hemispherical ram head on a manually adjustable shaft. A load cell is located on the ram head to measure the force being applied to the mattress.

Band Saws

Model: BP Series

With 2 blade speeds and a mechanical hand wheel system, the BP Bandsaws are perfect for thicker foam sample preparation (especially for porosity testing with model F0031). These units feature a quick-release blade tension mechanism as well as a safety magnetic switch with emergency stop.

Constant Deflection Compression Tester
