Resin casting is a method of plastic casting where a mold is filled with a liquid synthetic resin, which then hardens. It is primarily used for small-scale production like industrial prototypes and dentistry. It can be done by amateur hobbyists with little initial investment, and is used in the production of collectible toys, models and figures ...
Shell molding, also known as shell-mold casting, [1] is an expendable mold casting process that uses resin covered sand to form the mold. As compared to sand casting, this process has better dimensional accuracy, a higher productivity rate, and lower labour requirements. It is used for small to medium parts that require high precision. [2]
Transfer molding (BrE: transfer moulding) is a manufacturing process in which casting material is forced into a mold. Transfer molding is different from compression molding in that the mold is enclosed [ 1 ] rather than open to the fill plunger resulting in higher dimensional tolerances and less environmental impact. [ 2 ] Compared to injection ...
Thermosetting polymer. In materials science, a thermosetting polymer, often called a thermoset, is a polymer that is obtained by irreversibly hardening ("curing") a soft solid or viscous liquid prepolymer (resin). [1] Curing is induced by heat or suitable radiation and may be promoted by high pressure or mixing with a catalyst.
Bakelite (/ ˈbeɪkəlaɪt / BAY-kə-lyte), formally polyoxybenzylmethyleneglycolanhydride, is a thermosetting phenol formaldehyde resin, formed from a condensation reaction of phenol with formaldehyde. The first plastic made from synthetic components, it was developed by Leo Baekeland in Yonkers, New York, in 1907, and patented on ...
Sand casting. The cope and drag (top and bottom halves, respectively) of a sand mold, with cores in place on the drag. Two sets of castings (bronze and aluminium) from the above sand mold. Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand —known as casting sand —as the mold material.
