MOULDS FOR COMPONENTS
Mold is the Tool where the Hot plastics are Injected and Cooled to get desired shape and size. Because of the high pressures involved in this process, steel tooling is preferable. Aluminum may be used for low volumes and prototyping.

Injection Molding Machines
Injection molding machines can fasten the molds in either a horizontal or vertical position. The majority of machines are horizontally oriented, but vertical machines are used in some niche applications such as insert molding, allowing the machine to take advantage of gravity. Some vertical machines also don't require the mold to be fastened. There are many ways to fasten the tools to the platens, the most common being manual clamps (both halves are bolted to the platens); however hydraulic clamps (chocks are used to hold the tool in place) and magnetic clamps are also used.
The function of Injection Molding Process is to convert Polymer into the desired shape of Components. The polymer is heated in a cylinder under Pressure in a Machine called Injection Molding Machine. The desired shape is provided by a tool Known as Injection Mold. One of the earliest forms of Plastic Moulding was Compression Moulding. Here, a fixed amount of plastic is placed in the lower half of a mould and heated before the upper half of the mould is closed over the top of it. The mould remains closed while the part cools and when it is taken off the ‘Flash’
Most of the Raw Materials or Polymeric Resin can be used. The resin is in either pellets or in powder before processing. Some of the commonly used Polymers are
Polycarbonate ( PC )
Polypropylene ( PP )
Polystyrene ( GPPS )
Styrene Acrylonitrile (SAN )
Polyacetal ( Delrin )
Polyvinyl Chloride (PVC )
