ADMET offers a full line of grips and fixtures for materials and product testing. ADMET grips and fixtures can be used with virtually any manufacturer’s test frames and with ADMET retrofitted equipment.
Grips are categorized by the test type and the force capacity. Below is a list of standard ADMET grips. Custom options are also available.
Manual Vise
Manual vise grips are versatile general purpose grips for capacities of 50kN or less.
Pneumatic
Pneumatic grips are available as either wedge or vise types. They allow for rapid sample changes and constant clamping force. Pneumatic grips are attached to the testing machine using eye-end type adapters.
Wedge
Wedge grips easy specimen loading, alignment and positioning. They are well suited for testing high strength materials, such as metals and composites.
Rope and Thread
Rope and thread grips are applicable for filaments, cords, yarn, fine wires, narrow ribbons, ropes, etc. The guide rollers generate a slow notch free stress relief to prevent the breakage of the specimen in the clamping area. Pneumatic versions available for most grip designs.
Ribbon and Webbing
These grips are applicable for webbings and ribbons. The drums offer stress relief to prevent the breakage of the specimen in the clamping area.
Bend Fixtures
Bend fixtures are used to determine the flexural properties of rigid and semi-rigid materials. They are available in a variety of capacities, support diameter and widths, spans, and 3 or 4 point configurations.
Compression Platens
Compression platens are used to determine the compression characteristics of material samples. Platens are commonly manufactured from aluminum or steel and attach to the testing machine with an eye-end connector.
Pinching
These are versatile small tensile grips. Pinching grips are suitable for low force applications. They can be chain mounted for flexible positioning.
Peel Fixtures
ADMET’s easy to use adhesive test fixtures are employed by the adhesive industry to test the peel strength, bonding, and shear properties of adhesives.
Hydraulic
ADMET’s hydraulic grips are meant for high force applications with capacities up to 2,000 kN.
Self-Tightening
Self-tightening grips are ideal for materials that thin as they are stretched such as elastomers and other soft materials. They enable fast loading of materials like plastics, fabrics, films, and rubber.
Torsion
These grips are designed to hold samples during torsion testing.
Puncture Fixtures
These fixtures are designed to test the puncture resistance of materials.
