Extruder Die Flatness
Extruder Die Flatness Industrial Extruder Die Flatness Thickness Description Introduction: Extruder dies have a flatness specification that must be maintained or the parts being extruded will be out of tolerance and non-conformant, resulting in scrap and disruptions. Periodic inspection of the die for flatness, deformation, burrs, or other irregularities is required. Situation: A tool and die company approached MTI Instruments, requesting assistance with a new method for inspecting their 20 ft long die. Contact gauges on a gantry had been the previous method; Non-contact was now the preferred practice. Solution: [...]

Powdered Metal Level
Powdered Metal Level Industrial Powdered Metal Level Level Description Many precision and no-precision metal parts are made from powdered metal. The metal may be placed in a feed ram or delivered on a web/ belt. Some processes require monitoring of the powdered metal height and it may have to be kept level across the web. For small applications a single spot laser (Microtrak 4) or several lasers may be adequate to monitor the process (powdered metal height ) and call for more metal as the ram or belt supply gets too [...]
Ice Detection
Ice Detection Industrial Ice Detection Presence/Absence Description Introduction:  Ships take in water from outside the hull to cool the engines and other auxiliary equipment. The water usually comes in through a sea chest. “The sea chest provides an intake reservoir from which piping systems draw raw water. Most sea chests are protected by removable gratings (trash screen), and contain baffle plates to dampen the effects of vessel speed or sea state. The intake size of sea chests varies from less than 10 cm² to several square meters“(Wikipedia). Problem: Frazil are [...]
Fill Height Of Construction Blocks
Fill Height Of Construction Blocks Industrial Fill Height Of Construction Blocks Dimensions Description Introduction: When you construct a concrete block wall, the dimensions of the concrete block help ensure the structural integrity of the structure. Since the block is formed in a mold, the width and length are consistent; the height of the block is the variable. The amount of concrete dispensed in the mold, the pressure applied after filling the mold, and even sweeping the block after it is filled can all affect the overall height. The Problem: Many concrete [...]

Blade Tip Clearance
Blade Tip Clearance Power Generation Blade Tip Clearance Tolerances Introduction Blade Tip Clearance Solutions for Turbines, Fans, and Rotating Machinery When it comes to turbines and fans, blade tip clearance — the distance between the tip of the blade and the surrounding case — is one of the most crucial measurements. If the blade tips are too close, thermal expansion or vibration could cause destructive contact. If they’re too far, turbine efficiency and performance suffer. That’s why accurately measuring turbine blade tip clearance, fan blade tip clearance, or any [...]
Exploration Of The Elastic Region For Aluminum Alloys
Exploration Of The Elastic Region For Aluminum Alloys Research & Development Exploration Of The Elastic Region For Aluminum Alloys Bending, Tensile and Compression Description One of the most crucial properties of metals, including aluminum alloys, is their elastic characteristics, which define the extent to which a material can deform and return to its original shape once the applied load is removed. This behavior is particularly important when working with materials in engineering and industrial applications, where understanding the elastic region of the stress-strain curve is vital. The stress-strain curve for [...]
Tolerances of Armature Gaps
Tolerances of Armature Gaps Power Generation Tolerances Of Armature Gaps Tolerances Description Introduction In large motors and generators, the air gap needed to separate the revolving rotor from the stator should be as small as possible as this reduces the magnetizing power requirement. The gap also needs to be large enough to prevent contact between the two, despite manufacturing tolerances on their dimensions or movement resulting from mechanical deflection or looseness in supporting bearings. The gap should also be uniform; a non-uniform gap causes increased noise and vibration. Since large [...]
