Safeguarding against sequence and tightening failures requires you to deploy tools equipped with error-proofing capabilities that track each screw the tools fasten. Eliminate product rework and warranties by adding another layer of error-proofing to the manufacturing line. Common Sequence & Tightening Failures Under-tightening: Loose fasteners cause slippage between parts, placing unwanted shear stress Gasket creep…
Since the day we figured out the wheel, humans have separated ourselves by working smarter, not harder. After all, our bodies can only take so much. There’s no way we could transport, lift, and stack the granite and limestone of the pyramids without barges, ramps, and pulleys. Modern electric screwdrivers allow workers to manufacture the…
Imagine your job is lifting a five pound weight. Pretty easy, right? Most healthy adults don’t have an issue picking up something that light or even holding it about their heads for a few minutes. Pick it up, put it down, go home, get your paycheck. Unfortunately, your boss knows how easy it is for…
The daily repetitive process of fastening screw after screw with a power tool exposes operators to the risk of injury. An assembly operator freely holding and using a power tool is an opportunity for cross threading and side load to occur, which causes fastening failures. Implementing an ergonomic torque arm into the assembly process will…
Specifying a fastening sequence is a good manufacturing procedure to implement for many assembly projects. It can be critical for key torque applications. The wrong sequence could cause manufacturing failures and add additional rework expenses. The sequence of tightening bolts or screws can have a major influence on the resulting preloads. A good tightening sequence ensures…
A poorly designed and functioning assembly worksite leads to potential employee injuries and additional expenses can incur. With large volume manufacturing facilities, power tools are often used for tightening down fasteners. Assembly power tools increase productivity and reduce manufacturing costs. Tools that operate at high speeds increase risk factors. Power tools generally produce unwanted torque…
Many joints consist of more than one fastener and tightening together surfaces that are not completely flat can be a very challenging torque problem. The sequence of tightening fasteners can have a major influence on the resulting preload and clamping force, which is what holds two parts together. With such joints, consideration should be given…
The manufacturing process is constantly evolving in response to customer needs and emerging technology. Managing the assembly workstation, tooling requirements, production flow and employee safety is indeed a challenge. The daily repetitive fastening process exposes your assemblers to potential stress injuries. Increasing your awareness of ergonomic challenges and looking for ways to improve operator safety…
The ergonomic torque arms by Mountz eliminate torque reaction from both power and pneumatic assembly tools. With the EZ-Glider linear and articulated torque arms, a “downward assistant kit” can be installed on the arm to speed up and improve the production process. The system requires no effort from the operator to press downward on the…
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…
