To measure whether or not the scaled replica is a success, it must be able to extrude two seamless tubes. Specifically, both tubes should have an inner diameter of ten (10) millimeters, with one tube having a wall thickness of two (2) millimeters and the other tube having a wall thickness of four (4) millimeters. In order to perform this test, a block of Plasticine will be loaded into the container using the ram. Once the raw material meets the die, the mandrel tube will push out from within the ram, deforming the material into tubes by pushing the material through the die, following a fixed mandrel extrusion process. The mandrel tube will then reel backwards into the ram, to remove itself from the newly formed Plasticine tubing. Once the process is finished, two blocks of raw Plasticine material should have been used, with the results being two tubes of Plasticine. Calipers should be used to measure their dimensions to quantify the success of the replica.
However, the above only tests the extrusion's accuracy by measuring the dimensions of the resulting tubes. The designed machine should also be able to operate without problem, that is, it should ideally operate continuously for an entire workday without problems. To test this, the machine should be operated under repeated usage for several cycles and a prolonged amount of time. During the operation, there are several key features to examine. First, check to see that the die cover is snug, keeping the die restrained, as well as check whether the die cover is still secure as there is repeated stressing from extrusion. Second, check and verify that there is no leakage of input material backwards within the container in the space between the ram and container wall. Third, the motor should be able to continuously provide torque without breaking down or overheating. Fourth, the container's feet should be stable and fixed, with screws that are not damaged due to the cyclic, repetitive loading.
