0odular bench top mechanical test stands are intended for accurate force gauge testing up to 500lb (2.2kN) force.
Semi-automatic rig tests inhaler firing mechanisms
A semi-automated solution to test the firing mechanisms of pharmaceutical 'one shot' pressurised metered dose inhaler canisters is believed to be the first of its type developed.
Since many cartons are rectangular in shape when erected, they have two long and two short sides.
A jig has been designed with V-shaped grooved rollers, which retain grip on the box yet allow the box axis to rotate as it opens.
The jig has been designed for compression testing using the low force (1kN (225 lbf)) LFPlus single column universal materials testing machine.
It can also be fitted on other Lloyd Instruments test machines, when using an appropriate force load cell.
It is suitable for use with a wide range of carton blanks for consumer products, including boxes for 'ready meals', toothpaste and teabags, as well as carton blanks for cosmetic and pharmaceutical packaging.
Testing can be fully automated using the powerful NEXYGENPlus materials test and analysis software.
The introduction of the new fixture extends the range of materials test solutions for paper and paper board offered by Lloyd Instruments.
These include: tensile breaking strength for wet and dry paper, tensile energy absorption, bending stiffness, tear strength, tear resistance, folding endurance strength, paper stretch, burst strength and friction to TAPPI standards.
