Due to the advancements in electronic controls, mechanical engineers may have the tendency to bypass the use of gearing, as the robust gears used in machinery of high speed and high power are quite complex in design. However, electronics has a hard time beating gears for such dedicated, high accuracy requirements as in automobile transmissions. For a variety of internal machinery workings, gears are optimum for changing the rate of rotation, the direction of the axis of rotation, and rotary motion to linear motion. The multitude of gear types can be combined in many ways to create larger gear units, such as gear heads, gear boxes, gear reducers and gearmotors – which all fall under the category speed reducers.
From plastic gears for the smallest wind-up toy to two ton cast iron gears, the capabilities of gear manufacturers amaze me. I mean, being able to machine and cut gears from only a half inch through up to twenty feet in diameter is a pretty incredible range. Plus, being able to provide this kind of gear production all under one roof, turning out completely in-house customized and even emergency jobs – some gear manufacturers can do it all!
When I hear the word mezzanine, I immediately think of that field trip to an opera version of Romeo and Juliet in ninth grade. All I remember from that experience is sitting in the theater mezzanine wishing that those two star-crossed lovers would stop singing and just die already. But we did have great seats. A mezzanine in a theater is the lowest balcony, a nice elevated position to see all the action. Mezzanines in commercial and industrial settings serve a similar function of creating another level within a building.
Industrial Quick Search has been selected for the 2009 Best of Grand Rapids Award in the Marketing Consulting Services category by the U.S. Commerce Association (USCA). The USCA ‘Best of Local Business’ Award Program recognizes outstanding local businesses throughout the country. Each year, the USCA identifies companies that they believe have achieved exceptional marketing success in their local community and business category. These are local companies that enhance the positive image of small business through service to their customers and community.
The concept is this: rubber in all its various elastomeric forms and alternatives offers different levels of friction – or, simply put, grip or give – when bonded to a cylindrical core, creating rollers that can take on then apply substances (like ink or hot stamp foils, heat transfers or labels), collect unwanted particles, move objects along a conveyor, or offer necessary movement within various machinery and automated systems. From soft, spongy paint rollers to hard roller skate wheels, the consistency of rubber rollers varies depending on application: Does it need to be smooth or grooved, slick or sticky?
The full range of today’s hydraulic presses is some of the most powerful and versatile manufacturing equipment. Achieving the highest compressive force of all the power presses, these machines are crucial for the forming and molding of a wide spectrum of materials: metals, plastics and composites, rubber, wood, and laminates. From deep drawing essential parts, such as tanks and fenders, for the production of motorcycles to creating 2,640 plastic credit cards per hour, the manufacturing realm would be lost without hydraulic presses. The scrap metal processing industry also relies on shear hydraulic press force to smash discarded cars and such into compact, manageable squares of reusable material for pop cans, paper clips, etc.
You can almost hear the grinding and crushing as you say the word pulverizer – the consonants and vowels combine to create hard sounds as you enunciate through the syllables. I enjoy deepening my voice to emphasize the harshness of the word. You try… it’s like a ‘grr’ from the back of your throat. Now, while saying it (and making pounding motions with your fists if you really want to get into it), imagine what it would take to smash stones into powder. The bulk material handling and process industries, including mining, waste recycling, plastics, food & pharmaceuticals, rely on this kind of de-agglomeration controlled at various intensities within pulverizing machines, making materials more useful or reusable. It’s destruction with a purpose; breaking down to make better. Pulverizers take the idea of mortar and pestle to the extreme.
The many unique values provided by stainless steel make it a powerful candidate in materials selection. Engineers, specifiers and designers often underestimate or overlook these values because of what is viewed as the higher initial ost of stainless steel. However, over the total life of a project, stainless is often the best value option. Stainless steel is essentially a low carbon steel which contains chromium at 10% or more by weight. It is the addition of chromium that gives the steel its unique stainless, corrosion resisting properties. The chromium content of the steel allows the formation of a tough, adherent, invisible, corrosion-resisting chromium oxide film on the steel surface. If damaged mechanically or chemically, this film is self-healing, rovided that oxygen, even in very small amounts, is present. The corrosion resistance and other useful properties of the steel are enhanced by increased chromium content and the addition of other elements such as molybdenum, nickel and nitrogen.
From purely artistic and decorative to entirely functional, wire forms can come in a seemingly innumerable range of shapes and complexities. From simple wire ‘S’ hooks and peg board hooks to a complete rack of wire shelving or a rotating wire retail display, manufacturers that offer wire forming services are equipped to create many essential wire products for industrial, commercial and consumer use.
Laser welding is an effective method for joining small parts with tight tolerances. In the future, it will compete with traditional methods of welding or replace assembly/joining technologies benefiting industries that have never used laser welding before. Using light in the form of laser radiation as the energy source is a process used to achieve a balance between the process of thermal fusion and metallurgical effects. Functionally, the laser generates infrared or visible light (usually with the use of Nd-YAG lasers or frequency-doubled ‘green’ lasers for reflective metals) which is delivered through an optical fiber and focusing lens onto the workpiece. Welding is the process that occurs when laser radiation is absorbed by the workpiece and turned into heat raising the temperature in the localized area above the melting point…
It’s not by magic that forging has survived and thrived as technology has advanced. The heart of forging has not changed since its origin in ancient Egypt. From the pre-industrial age on into today’s sophisticated forging facilities, the essence of forging remains the same: how it affects the structure of metals. The results are unequaled in any other form of metalworking. Discussing the different types of forging can get very complicated. Putting it more simply: heating the metal until it’s malleable breaks down the originally coarse grain structure, and then ‘kneading’ it between dies elongates the grains and they recrystallize in a new finer granular structure…
by PSI Extrusions The aluminum extrusion process, which involves forcing hot aluminum through a precision die to create a length of constant cross-section, marries the inherent advantages of aluminum to the precision and high volume capacity of the extrusion process.
Although one of the world’s oldest metal fabricating technologies, investment casting (sometimes known as ‘lost wax’ casting) has in recent years been subjected to a few misconceptions, ironically these fallacies have probably caused many who could have benefited most from this process to rule it out…
