Innovative Torque Control Systems for Automation and Robotic Fastening Applications

Posted by Mountz Torque October 2nd, 2014 0 Comments   

As new products emerge and demand grows, the manufacturing process is evolving rapidly. Automation and manufacturing engineers must adapt quickly and solve new sophisticated production challenges. There are many opportunities to improve the production process. Refining manufacturing methods and implementing automation equipment are significant opportunities.

Innovative automation fastening systems provide the ability to quickly transform the manufacturing area along with the flexibility to make steady product improvements for small or large production batches. Today’s fastening process is really about providing quality torque control for manufacturers with a greater ability to achieve repeatable performance, optimize production and remain cost competitive. Electric screwdrivers engineered for robotic and automation applications provide manufactures with a rapid, reliable and precise method of fastening screws. The technology of these automation tools provide tighter process control and higher quality standards, while keeping costs down.

Mountz offers the next generation of automation and process control in screw fastening technology. The SD-Series and HD-Series are a versatile torque and automation control systems engineered for precision accuracy and repeatable torque control. The Mountz automation tool systems improve productivity and efficiency with six key essential manufacturing benefits:

Torque Multipliers for Plate Heat Exchangers

Posted by Mountz Torque September 26th, 2014 0 Comments   

Plate heat exchangers are designed to provide highly efficient heat transfer for various industrial applications, like chemical and food processing.  Regular maintenance intervals for plate heat exchangers are needed in order to maintain production efficiency. Overtime, dirt, silt, sand and other debris can build up and impact the heat exchanger’s performance and cause unplanned downtime. Heat exchangers can easily be disassembled and reassembled to allow for cleaning.

A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids. The device is composed of a number of thin corrugated metal plates compressed together into a “plate pack” inside a frame by two pressure plates.

Maintaining these plates requires a regular and intensive cleaning process. Part of the maintenance process involves loosening and retightening the pressure plate “tightening bolts” using a quality torque multiplier.  Accessing the metal plates, within the plate heat exchanger requires a disassembly process. The tightening bolts need to be loosened evenly in small steps using sequence pattern (diagonally and alternating sides), in order to prevent any overload with the individual tightening bolts and tilting the pressure plate. Once the heat exchanger is opened, the plates are removed for the cleaning process.  After the plates are inserted back in, then the heat exchanger needs to be assembled back together. The tightening bolts need to be properly tightened to the proper torque specification using the torque multiplier tool.

Clean Room Manufacturing & Assembly with Clean Room Torque Screwdrivers

Posted by Mountz Torque September 18th, 2014 0 Comments   

Manufacturing electronic, semiconductor, biotech and medical devices demand care and precision. Often a controlled environment is needed during the production process to limit the amount of dust, particles and other contaminants in the manufacturing area. A clean room environment controls the level of contamination. Eliminating any sub-micron airborne contamination is a controlled process. Clean rooms are used in many industries where small particles can adversely affect the manufacturing process.

There are nine different levels of clean room classifications by ISO (International Standards Organization). The clean room classifications are rated according to how much particulate of specific sizes exist per cubic meter. The lower the ISO classification, the cleaner the environment. The “cleanest” clean room is a class 1. A clean room environment involves many different elements like clean room garments, clean room HVAC systems, modular clean rooms and other sophisticated equipment.

With the demand for clean room manufacturing increasing, the need for torque tools that meet stringent cleanliness requirements has increased. Responding to this industry need, Mountz offers a selection of clean room torque screwdrivers. The hand tools are manufactured to comply with Class 100 Clean Room standards (ISO 2) and are polished and sealed with a PTFE impregnated anodized coating that creates a tool nearly 40 times as clean as “off the shelf” torque tools.

Cam-Over Torque Wrenches Reduce Fastening Failures

Cam Over Torque Wrenches

Fasteners and bolts are commonly used to securely clamp two or more items together. Although these components seem like a small part of the design and assembly process, it shouldn’t minimize their importance. Improperly tightening fasteners can unknowingly cause catastrophic or latent failures. Lack of torque control for fastening applications has caused wheel detachment on vehicles, failures with life saving medical instruments and prevented electronic devices from functioning.

Investigating failures in the fastening process is costly and time-consuming. Common elements that can be attributed to fastening failures are:

1. Failure of improper torque control: under tightening and over tightening a fastener
2. Selecting the incorrect torque tool for the fastening application
3. Improper design and torque specification
4. Lack of torque testing for joint relaxation in fastened joints
5. A non-calibrated torque tool is used for the fastening application

The technology used in a cam-over wrench prevents fastening failures and ensures proper torque control. The Mountz cam-over torque wrenches are designed to provide reliable and precise torque control for bolting applications that do not tolerate over-torque conditions. Improper torque control increases manufacturing costs and delays. Using a cam-over wrench removes the operator influence out of the fastening process and offers precision and repeatable torque results.

Six Tips for Establishing a Quality Torque Control Program

Quality Torque Control Program

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 can spell the difference between a safe, reliable, and economical product and complete disaster. A quality torque program helps increase productivity, reduce rejection rates and make the assembly worker’s jobs easier.

Anybody who has to tighten a threaded fastener and needs to control, monitor, or measure torque needs sophisticated torque tools. If manufacturers want to save money, make their workplace safer, enhance product quality, or reduce their exposure to liability; only specialized high-quality torque tools will get the job done properly.

1. The Importance of Torque Control
The reliability of machine parts subjected to fluctuating loads and stress depends on the fatigue strength of the materials. A threaded fastener, however, relies upon an elastic interaction between the mating components. Its objective is to clamp parts together with a tension greater than any external force trying to separate them. The bolt then remains under almost constant stress and is immune to fatigue. If the initial bolt tension is too low, the fluctuating load in the shank in much greater and it will quickly fail. Reliability, therefore, depends on correct initial tension and is ensured by specifying and controlling the tightening torque.
