Screw torque traceability control: industrial application

Selection and Application of Industrial Screw Compressors

Sequential calculation of torque in procedure of twin screw extrusion

The drug making resreach has accentuated on extrusion technology for a long time. The advance of drug bioavailibility, bead manufacturing and granulation is assured by extrusion procedures. There are also diverse effects in resereches with respect to the use of process understanging as a tool in quality management. Many initiatives of FDA such as PAT and QBD are getting accepted. In this survey...

Industrial Application of Magnetoelastic Force and Torque Sensors

Due to their sensitivity, robustness and the flat shape, the magnetoelastic sensors create new possibilities of industrial applications. This paper presents the results of the field tests of using the magnetoelastic sensors with amorphous alloy ring-shaped cores for ignition detection in locomotive’s diesel engines as well as measurements of the torque during the operation of ball valves. Prese...

The Effect of Torque Application Technique on Screw Preload of Implant-Supported Prostheses.

PURPOSE To examine the effect of different torque application techniques (torqued, retorqued once, and retorqued twice) on the removal torque of implant-supported fixed complete dental prostheses. MATERIALS AND METHODS Four Nobel Biocare implants (4.3 × 13 + 3; 13-mm thread height + 3-mm collar height) were stabilized temporarily inside four holes made in an acrylic mandibular master model. A...

A comparison of screw insertion torque and pullout strength.

PURPOSE Pullout strength of screws is a parameter used to evaluate plate screw fixation strength. However, screw fixation strength may be more closely related to its ability to generate sufficient insertion because stable nonlocked plate-screw fracture fixation requires sufficient compression between plate and bone such that no motion occurs between the plate and bone under physiological loads....
