(prHWY.com) January 31, 2013 - Saint Petersberg, FL -- Nearly a third of all plastics by weight are now-a-days processed using injection molding process, which was invented nearly four decades back in 1972. Since then, the plastic industry and the injection molding business have become all the rage and ballooned into a multi-billion dollar business venture. The injection molding process has helped economies a lot by enabling the industry to produce cheap as well as durable items essential in the consumer and industrial sectors.
Functions of the
injection molding machine: The injection molding machine is used to convert granular/pelleted raw plastics into final molded parts. It completes the process via the use of a melt, inject, pack & cool cycle for thermoplastics. We can classify injection molding machines into three categories: general purpose molding machines, tight-tolerance molding machines and high-speed thin-wall molding machines. All of these machines require auxiliary equipment, such as resin, granulators, mold temperature controllers, chillers and material handling equipment, to function. A number of companies use these machines to offer specialized injection molding services. The injection molding machines are capable of performing fast, flexible as well as customer driven molding functions. Companies specialized in injection molding process usually have state-of-the-art facility with full-blown thermoplastic as well as thermoset capabilities. The companies are also equipped with computer-aided manufacturing facilities,
skilled machine operators plus quality inspectors, who make sure that the plastic process by their company is of superior quality.
Basic components of an injection molding machine: basically, an injection molding machine is composed of an injection system, a hydraulic system, a mold system, a clamping system and a control system. The clamping system plus shot size of the machine are used to identify the dimensions of the injection molding machine for thermoplastics.
Injection check valves are used to allow the flow of fluid across a port or pipeline system in a particular direction. These valves are activated by the amount and pressure of the fluid present in the system of the machine, and are used usually in back flow prevention applications, flood prevention environments as well as waste-water treatment entities. Duckbill-shaped injection check valve design is capable of responding to changes in the pressure of fluid. This design allows the valve sleeve to close in response to rear flow of pressure. It forms a tight seal that blocksd debris from entering waterways. This injection check valve design has also been found very effective in low pressure applications and in pollution prevention efforts on larger waterways.
Injection check valves are apposite for a range of other applications as well. This design is ideal for manhole as well as end-of-pipe outfall installations. Certain models are also used in industrial applications like corrosive slurry handling, caustic chemical applications and high-temperature chemical reactions. Injection valves are also installed for the purposes of control of sewer system and prevention of sewer backflow.
