Fabrication is the process of making components out of raw materials. The act of putting those pieces together is known as manufacturing. While the two frequently coexist, there are times when one of them could be more appropriate for a certain project.
Building a product for producers, not customers, is what fabrication entails. Fabricators prepare components for assembly by processing raw materials or refining parts. Although there are nearly endless alternatives, some of the most popular manufacturing techniques include: Cutting, Welding, Folding, Machining, and Stamping.
The technique of molding plays a significant role in the field of plastic processing and is appropriate for the mass manufacture of goods with complex forms.
The basic process of an injection mold is: by heating plastic ingredients until they are molten, then injecting them into a mold where they cool and solidify, you get the final product.
There are five major steps involved. The first being clamping, followed by injection the plastic into the mold, letting the mold cool, opening the mold, and then the removal of the product.
Most metals can be brazed, and as new alloys and service requirements are developed, the variety of brazing alloys that are readily accessible expands. As long as the joint is properly fluxed, torch heating in air is OK.
Brazing is a joining method that uses heat and a filler metal to fuse two pieces of metal together. This filler metal is either pre-placed or supplied into the joint when the pieces are heated. It has a lower melting point than the metals to be connected.
