Did you know that an incorrect screw fastening sequence can provide unreliable results? The wrong sequence could cause manufacturing failures and add additional rework expenses. Joint relaxation occurs to some extent in all fastened joints and is a problem in joints where gaskets, or parts such as spring washers and plastics, are utilized. It can…
Flat-pack furniture famously exported by Scandinavia offers practical lessons about the importance of assembly line ergonomics. Assembling the furniture doesn’t seem difficult, especially if you have your own power tools, along with the small disposable screwdrivers and hex keys that come with the furniture. However, once you have it assembled, you may find your hands…
In the manufacturing and assembly world, tightening, controlling, and measuring torque are imperative for production efficiency and reducing manufacturing costs. A fastener inadequately tightened can vibrate or work loose: conversely, if the tension is too high, the fastener can snap or strip its threads. Faced with these problems, manufacturers are realizing that precise torque control…
Whether your manufacturing staff is assembling components used for electronics, aircraft, automobiles or appliances, it’s important to identify potential ergonomic risk factors. Power tools, both electric and pneumatic type, generally produce unwanted torque reaction that transfers over to an operator’s hand. After a while, the daily fastening process will expose your operators to repetitive stress…
