A mold coating agent test device includes a frame positioning portion and a connection positioning portion. The frame positioning portion positions a frame portion of a metal mold such that the frame portion of the metal mold is positioned at a predetermined position when the metal mold is placed on a metal block. The connection positioning portion positions a connecting portion such that the connecting portion that is a portion provided in the frame portion and to which a drive unit that applies a force is connected is positioned at a predetermined position when the metal mold is placed on the metal block.

The invention relates to a force measuring arrangement (3) in particular for applying a test parameter to a specimen and/or for measuring a resistance force applied by the specimen, having at least one force absorption element (25), a first fastening device and a force transmission element (27), wherein the force absorption element (25) can be fastened to a force measuring device in a movable manner by means of the first fastening device, wherein the force absorption element (25) is designed to measure a relative force acting between two force absorption regions, namely a first force absorption region and a second force absorption region (51), wherein the first fastening device is able to be connected to the force absorption element (25) in a force-transmitting manner via the first force absorption region, wherein the second force absorption region (51) is able to be connected to the force transmission element (27) in a force-transmitting manner by means of a second fastening device, wherein the force transmission element (27) is designed to apply a test parameter to a specimen. The force measuring arrangement is notable in that the second fastening device has a magnet (37) that is designed to retain the force transmission element (27) at least in a state connected to the second force absorption region (51) in a force-transmitting manner.

Described herein are examples of improved material (and/or universal) testing machines having a lower crossbeam that may be moved via a drive system of the material testing machine. In some examples, this may be accomplished via drive shafts with different threading in upper and lower portions, and/or independent drive systems for upper and lower crossbeams. The ability to dynamically adjust (e.g., raise) the lower crossbeam may allow an operator to interact with test samples at a more comfortable height, and reduce the need for an operator to repeatedly bend and/or kneel.

The present invention relates, in part, to systems for characterizing force (e.g., friction, and wear). In one embodiment, a tribometer allows for wear testing of samples in a high throughput manner.

The disclosure is directed at testing machine for material samples. The testing machine includes a loading station and a testing station along with a pick and place apparatus that moves the material sample being tested between the loading station and the testing station. A control system controls movement of the material sample. The control system also generates testing machine parameters along with testing parameters.

An apparatus includes a holder to support an indenter relative to a sample, a depth sensor, and a controller. The operations include applying a first force on the sample with the indenter and determining a first depth of the indenter based on data generated by the sensor, moving the indenter from the first depth to a greater predetermined depth, then applying the first force on the sample with the indenter and determining a second depth of the indenter based on second data generated by the sensor, and determining a value indicative of hardness of the sample based on a difference between the first depth and the second depth. The apparatuses described can use a single scale for hardness that enables hardness values for different materials to be compared to one another.

The present invention relates, in part, to an apparatus configured to test a plurality of test samples within a sample cartridge. Such an apparatus can facilitate high-throughput tensile testing of such test samples. Also described herein are methods for using such an apparatus and for testing such test samples.

A system and method for performing a tear test are described herein. The system may include a fixed clamping station configured to hold a first portion of a film specimen and a movable clamp coupled to an actuator, the movable clamp may be configured to hold a second portion of the film specimen. The movable clamp may be configured to move in a direction away from the fixed clamping station to tear the film specimen. The system may include a slitter blade configured to cut the film specimen at a location between the fixed clamping station and the movable clamp. The system may include a load cell coupled to one of the fixed clamping station and the movable clamp. The load cell may be configured to measure a force associated with tearing of the film specimen. The actuator may be configured to manipulate the movable clamp along a trajectory.

A hardness tester includes an indenter, an arm and a driver which loads a test force onto the indenter and press the indenter against a sample, a spring displacement amount sensor detecting a value for the test force loaded onto the indenter, and a controller. In a state where a predetermined test force (total test force) is loaded onto the indenter by the driver, when the value of the test force detected by the spring displacement amount sensor exceeds a predefined allowable margin relative to the predetermined test force, the controller executes predetermined processes, including an interrupt process interrupting the test currently being executed and a notification process notifying a user that the value of the test force exceeded the allowable margin during execution of the test.

The invention comprises an apparatus for testing mechanical materials, including, but not limited to, plates, welded pipes, metal shells, and the like. The apparatus may include an outer module; an inner module, wherein the inner module is affixed to a target mechanical material to be tested; and at least one main bolt, wherein the at least one main bolt physically contacts the outer module and the inner module. In some embodiments, the inner module may include a plurality of clasps for holding the target material. A mechanical force can be applied to the main bolt, which results in application of mechanical force to the target mechanical material for testing. Additionally, the apparatus does not require any hydraulic elements or electrical elements.
