Skateboard wheels were first invented in the early 1900s. A few inventive children took old roller skate wheels and attached them to 2 by 4 boards. The original skateboard wheels were made from steel, and were very difficult to use, because the wheels had very little traction.
A grizzly screen provides a simple, initial sorting method for rough materials. Grizzle screens are mainly used in mining and other sorting industries where it is necessary to sort materials by size. Grizzly screens were first used several hundred years ago, when mining first became industrialized. Since the early invention of grizzly screens, the machine has changed several times to evolve into a machine that works with modern manufacturing and mining processes.
Polyurethane bushings are one alternative to automotive bushings made from synthetic or natural rubber. Polyurethane is usually harder than rubber, and offers different features and benefits than natural rubbers. If you are considering switching the bushing material in your automotive production, consider the potential benefits that polyurethane bushings can bring:
There are many different kinds of chillers used in industrial process. Chillers are used to cool machines, prevent sparks and other problems while fashioning parts, keeping rooms cool, and preventing liquids from evaporating. There are water chilling machines, air chilling machines, evaporator chilling machines, and vapor compression chilling machines. This wide variety of chilling machine types make it possible for any industry to find the best cooling system for their unique needs.
Industrial ovens are a necessary part of many different factory processes. Ovens are used to cure, bake, cook, dry, heat, and perform many other functions in factories. An industrial oven is usually created for a specific purpose, such as a large bread oven or ceramic-drying oven. In general, ovens cannot switch functions. In the industrial world, there are six different types of ovens that help facilitate industrial processes on a large scale. These ovens include:
Having worked in the food service department of a college as a sous chef and a caterer I have had my fair share of experiences with industrial ovens that were made for baking. Making massive amounts of food for hungry college students requires a series of very large baking ovens that are designed with numerous racks so more then one thing can be cooked or baked at once. That is why an industrial baking oven can also be known as a batch oven. Regardless of what it is called, a baking oven in a commercial context such as a school or a catering business is used for the mass production of food and therefore must live up to the same sorts of standards imposed on other industrial machines.
In order to position, lower and raise work tables or platforms one must use a lift. The three typical types of lifts are electric, hydraulic and pneumatic. Electric lifts utilize electricity from a power source such as a battery or an electric motor. This electricity provides mechanical energy, such as the lifting and descending motion, to the lift’s components.
Chocolate is one of my favorite things in the world. I love nearly any kind of chocolate, from barely sweet to creamy white chocolate. Until recently, I never really thought about how chocolate arrives at my door. Even though I knew millions of chocolate pieces were made each day, I never thought about how it could happen. The trick to making large quantities of chocolate in any factory is, like many other factory process, conveyor belts. Without these conveyance systems, making chocolate and other candies would take much longer, and probably cost a lot more.
Aluminum extrusion is the process of creating unique aluminum shapes through the use of machining and metal dies. Most manufacturers choose the extrusion process over other metal forming processes because it is easier to make complex or unique shapes through the use of aluminum extrusion. The aluminum extrusion process also makes it possible to create hollow extruded aluminum shapes, which are ideal for creating unique machine parts and other hollow pieces for a variety of uses.
The metal extrusion process is a popular process in the metal fabrication world because it can produce long, strong pieces of metal formed from one solid piece of metal. In both hot and cold extrusion processes, a piece of metal is pressed through a die under enormous pressure. The pressure from the die shapes the metal into the desired finished shape. The pressure and lengthening of the metal gives the metal extrusions remarkable strength, even if they are thin and narrow pieces when the process is complete. The extrusion process is used to create a variety of shapes, including the t shape aluminum extrusion, c shaped extrusions, l extrusions, and h extrusions.
