Steam injection molding is also referred to as RHCM. Rapid Heat Cycle Molding.
In general ABS material is used as the raw material.
The primary advantage of steam injection is that it eliminates weld-lines on molded parts. This allows companies to eliminate future processes such as painting from the production process.
In non steam molding, water will heat the tool to a constant temperature (say 60 degrees). Plastic will be injected to the warm tool.
In steam molding, steam is injected at 160 degrees to heat the tool. When the tool reaches a predetermined temperature (about 140 degrees) the plastic is injected. Cold water is immediately added to the process to cool the plastic down to around 40 degrees.
Because the mold is so hot when the plastic is injected, there are no weld lines & you should end up with a 'perfect' product. Steam injection molding is now being extensively used to produce the front covers of LCD TVs.
Expain 3 shot injection molding process
In injection blow molding starting parison is injection molded rather than extruded. In extrusion " " extrusion of parison occurs. There is three steps in injection blow molding: injection, parison and ejection. Tooling cost is higher in injection blow molding. one more, hot knife cut off the resins coming from heating zones before these goes to mold.
Humber College used to teach about injection molding and plastics industry. It was a really great program for someone who wants to be in this field. I don't think any other college or university teach about plastics injection molding anymore. I wish Humber can start teaching about injection molding again in future.
Plastic Injection Molding continues to advance as the new technology emerges and it brings new opportunities in automotive manufacturing. Automotive Injection Molding reduces the weight of all vehicles, which increases fuel efficiency without sacrificing the power. The less weight an engine must move, the more responsive the engine becomes for driver. Plastic injection molding lowers the total weight, hence fewer emissions. With so many interior and engine parts currently made with plastic injection molding processes, the weight of the largest cargo hauling vehicles is dropping increasingly.For more information about plastic injection molding and medical injection molding, please visit advancedplastiform

You can find injection molding on websites online. One such website I found online that has injection molding is http://www.plasticstoday.com/imm.

There are several online resources for rubber injection molding.I would suggest checking out www.CustomRubberCorp.com. Rubber injection molding can be ordered from companies that specialize in injection molding. These companies typically are suppliers to the auto industry.
Qualiform Rubber Molding (www.qualiformrubbermolding.com) and Custom Rubber Corp. (www.customrubbercorp.com) both manufacture rubber injection molding.

EVA injection molding is a versatile process with a variety of applications. EVA injection molding is used in many industries, including the mass production of sporting goods and toys. In the sports industry, EVA injection molding is used to make everything from shoes to helmets.
Injection molding is the manufacturing process for producing parts from thermoplastic and thermosetting plastic materials.
Injection molding is a process in whih the material normally plastic,is injected into a mold to produce a componenet.
Plastic injection molding is a complex form of molding that uses plastic pellets and you heat them into a desired shape. Plastic injection molding can be very expensive when purchasing tools. To find more information on plastic injection molding go to http://www.engineersedge.com/injection_molding.htm.
There are a few ways to compare injection molding machines. Compare the materials used in the creation of the mold, heater, hopper, and barrell. Better injection molding machines will be made from steel, and not from aluminium.
