Gripping a sample correctly for testing is a fundamental aspect of test repeatability. The sample must be held firmly enough not to slip, but not so as to distort it, or introduce localised changes in sample performance under load.
Appropriate fixtures combine:
• characteristics for load or torque
• size capacity
• the surface of the grip faces
• the method of tightening
• adjustment for alignment
• interchangeability
In industry standard methods, the method of gripping is often specified. Mecmesin can provide a full range of approved grips and fixtures for use with all our systems and instruments. Our accessories catalogue includes load and torque cells and sensors, cables and peripherals, grips and cradles: everything you require for a complete testing solution. For more details, Click here
Grips and fixtures are integral components of a complete closure testing system. Gripping samples correctly for testing is a fundamental aspect of test repeatability, and consideration must be given to both the closure itself and the container, if appropriate to the test. The sample must be held firmly enough not to slip, but not so as to distort it, or introduce localised changes in sample performance under load
Mecmesin offers a range of standard grips to hold or operate the closure (usually the upper grip) and the container (usually the lower) in both torque and force testing applications. For specialized requirements, our team of experienced engineers can design customized fixtures, such as cap mandrels, to match your particular criteria specifications. Mandrels can be custom-sized, split or pneumatically operated, and appropriate for plastic, metal or cork closure materials.

Very many test applications require custom fixtures in order to:
• avoid distorting the test sample
• ensure concentric rotation for torque
• provide accurate alignment for tension or compression
• support a flexible sample
• hold an asymmetric design
• grip a specific part or parts of the specimen
Mecmesin design engineers have unparalleled experience in custom solutions, and we welcome any enquiry. Use this facility to see illustrated examples of what we have recently designed and manufactured to meet specific needs.
Custom fixture design service
When testing flexible, moulded or asymmetric items, custom grips are often required. We have an expert in-house design and manufacturing facility for these specific needs. These typically include vacuum fixtures for preform packaging, cap mandrels to fit specific designs, grips for control devices with moving parts, jigs for bending awkward or large items, fixtures for torsion springs, guards and containment, and many more.
