Insert bits are removable pieces found in manufacturing tools, from screwdrivers to lathes. They offer advantages such as easy maintenance, versatility, and cost-effectiveness. The bits can be small or large and are attached to machines. By replacing worn-out bits instead of entire assemblies, costs are reduced. Different functions can be achieved by changing the bit. […]
The Allen screw, also known as a hex head screw, uses an Allen wrench to tighten and remove. It is a high-strength fastener made from various metals and is commonly used in machine building, high performance, and aircraft applications. The fine thread pitch holds tight without the need for lock washers or nuts, and the […]
An absorption tower separates gas components by using a falling liquid to trap the rising gas. It needs to be custom designed, regularly cleaned and maintained. Gas is pumped to the bottom of the tower and impurities float to the top, where aerosolized liquid is sprayed to capture them. Absorber towers are commonly used as […]
