What’s colorful, trendy, totally malleable and dirt cheap? Plastic, of course! Plastic is the most easily available substance and can be turned into just about anything you want. Plastic materials are considered more durable than metal, and their lightweight makes them suitable to make a variety of things that if made in metal can be infinitely more difficult to carry around!
By definition, plastic materials are synthetic or semi-synthetic organic substances available in amorphous solid form. Manufacturers of industrial products sometimes add other substances to improve quality and bring down costs. Plastic is of two types: thermoset and thermoplastic. The former include things like plates, glasses, circuit boards, etc that retain their shape until burnt and destroyed. Thermoplastics, on the other hand, melt as soon as they are exposed to heat. These include things like grocery bags, piano keys, some motor parts, etc.
Plastics aren’t restricted to one category. The common kinds of plastics include Acrylic, Delrin, Teflon, PVC, PFA and others. Ever since plastic was invented, it has been giving its metal counterparts some really tough competition. Some machined plastic materials are considered more reliable than metal items. Through a process known as milling, plastics can be molded in to any desired shape or size, depending on requirement. Plastic material machining, however, is no child’s play and is perhaps, more complicated than metal machining. One needs experts to machine plastics in the right manner, so as to create articles that will continue to last. Factors like unusual shapes, close tolerances and quantities to be produced need to be considered.
