Today, sick of being waiting to be educated like Malaysia's education system, I decided to take the task into my own hands and of course the destination-middle inspection section. Who is a better teacher material candidate none other than the middle inspection head herself. As i watched, she deftly completed a tensile test on the welding of the hybrid damper with practiced hand. First, she cut the bottom of the hontai made of TPE (only the top are welded together) and removed the grease contents within. Next, she uses a soldering tool to create 3 holes, one at the top and 2 at the side below the weld located exactly opposite of each other on an imaginary horizontal axis. Then, she drive what looks like a long thumbtack with the pointed edge going through the top hole from the bottom and a metal rod is inserted into the other 2. After that, the product is secured at the rod on the lower jaw that stays stationary while the upper jaw secures the edge of the thumbtack and moves upwards in the test. Hence, if the welding is stronger than the applied force then the hontai structure will yield whereas vice-versa the cover (futa) and hontai will be separated. In short, this test is just one of the many hourly test that the middle inspection conducts on finished products. This is to ensure no NG overflow to the customers. Other than that, NG products are also expelled through jigging in which a metal/plastic mould with a gap for height tolerances for that particular product will be used. There are 2 possible manual rejection scenarios, can't fit-height is over & pass through-height too low. Well, there are still several test and mechanism that I didn't managed to grasp at the moment which I intend to master if given the chance.
