Ribbon Steel Cutting dies are manufactured by means of a wire EDM process and then hand sharpened to a fine edge. Along with shear strength, shore hardness is also a good indicator of how resistant a astn is to being cut with a die and press.
Testing Procedure Prepare the test pieces and place them in the grips of a testing machine using care to adjust the test piece so that it will be strained uniformly along its length, and that sufficient material is clamped in the grips to minimize slippage.

ASTM D Elastomer Tear Strength Testing - ADMET
All purchase orders must be postmarked or recieved no later than January 5 thto qualify. A protective coating of industrial enamel is applied to the non-cutting surfaces before undergoing a rigorous final inspection.
For Type T or CP test pieces, take a continuous recording of the force throughout the tearing process. Adtm duty steel dies are also available for cutting thicker, higher strength materials.
ASTM D Specimen Cutting Dies A, B, C & T
Rated to 1 kN lbf Maximum specimen thicknesses from 10 mm to 50 mm 0. By switching your machine to load control, you can be sure to not overload your system. For ASTM CD, you may use an electromechanical universal test machine along with a pneumatic or mechanical set of grips. Click Highlighted Picture for Cut Sheet.
The force acts along the major axis, the direction of the slit, in a direction parallel to the length. Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more.
The force acts along the major axis, perpendicular to the nick and measures tear propagation.
Link to Active This link will always route to the current Active version of the standard. A spring loaded backstop ensures even loading and prevents the sample from getting stuck inside the die after the cut is made. Different cutting dies are used depending on the sample type.
ASTM D624 Elastomer Tear Strength Testing
Record the maximum force for Type A, B or C test pieces. This measures tear propagation and is widely used in the testing of textiles, coated fabrics, and similar materials. Universal Grip offers chrome plated steel molds and casting trays for preparing sheets ashm elastomers and soft plastics. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
GK Mechanical Vice Grip. UGC offers Routing Jigs and Machining Guides which can aid in the machining process on thicker materials and metal samples.
Hardened Steel cutting dies are more robust and are used for cutting harder sheet materials from mm thick. This is a great solution to use if your laboratory does not already have an arbor press.
If the material is too strong to be cut with a die and press, it can be machined into the appropriate dimensions. Please Request a Quotation for current pricing and delivery.
CCSi manufactures these high quality UltraLife Specimen Cutting Dies for evaluating the tear strength of conventional vulcanized thermoset rubber and thermoplastic elastomers, as described in: Work Item s - proposed revisions of this standard. Strain the test piece until it is completely ruptured.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. A hard nylon back plate supports the material and allows it to be cut evenly and cleanly.
Each undergoes multi-axis precision grinding and conventional, plunge, or wire EDM Electrical Discharge Machining processes Ribbon Steel Cutting Dies. Prepare the test pieces and place them in the grips of a testing machine using care to adjust the test piece so that it will be strained uniformly along its length, and that sufficient material is clamped in the grips to minimize slippage.
