Injection molding is a commonly used manufacturing process for the fabrication of plastic parts. the injection molding process need injection mold and injection machine.
--------------------------------------------------------
Injection molding is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the mold cavity.After a product is designed, usually by an industrial designer or an engineer, molds are made by a moldmaker (or toolmaker) from metal, usually either steel or aluminium, and precision-machined to form the features of the desired part. Injection molding is widely used for manufacturing a variety of parts, from the smallest component to entire body panels of cars.
the following is a photo of the injection molding process:http://www.vulcanmold.com/article/Plastic-Injection-molding-process.html
A Hollow mould is made from steel in several parts. when the mould is all together the hollow within it is the same shape as the object you wish to produce. The mould is water cooled to keep its temperature under control. molten plastic is forced into the mold at high pressure. it is left to cool for a specified period of time, then the mold is pulled apart in such a way that the object falls out of the mould and the whole thing starts all over.

What is relation of shot capacity and shot weight in plastics injection molding?
Shot Capacity : The maximum weight of molten resin that the injection molding machine can push out with one forward stroke of the screw during injection molding operation. Shot weight : The weight of the material injected into the mold in a single shot by an injection molding machine. (Weight of the molded part(s) + Weight of the runner + gate and the sprue)
What Types of ejection systems are used in injection molding?
sleeve ejection,blade ejection,srriper plate ejection,pin ejection,valve ejection
What are the Main parameters that affect the injection molding process?
Following parameters affect injection moulding process. 1) nature of material (type of plastic) 2) rate of injection 3) size of the component being moulded 4) efficiency of machine 5) type of cooling method adopted 6) curing time in the mould
What is the difference between injection molding and transfer molding?
The difference is within the machine and processThe presses used for injection molding are horizontally operated with a unique material delivery system. The thermoset compound is fed and injected with a high speed reciprocating screw, or a plunger system that reduces glass degradation for better part strength. The major advantages of injection molding:Better for small to medium part sizes (0.1 lbs to 6 lbs) in high volume.Tight tolerances can be achieved with these low-shrink materials. Post curing is not needed.Consistent material delivery into the mold cavities.Good strength for small parts, especially when molded with Thick Molding Compound (TMC).The presses used for transfer molding are vertically operated and equipped with a hydraulic transfer system and controls. The thermoset compound is loaded into a chamber known as the transfer pot. The mold is then closed and a transfer plunger forces the compound from the pot through the runner system and gates into the mold cavities. The major advantages of transfer molding:Better for small to medium part sizes in medium to high volume.Good for molding in complex metallic inserts into the part (encapsulation).Tight tolerances can be achieved with these low-shrink materials. Post curing is not needed.Consistent material delivery into the mold cavities.

Where can I order rubber injection molding?
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.
What kind of business does rubber injection molding?
Qualiform Rubber Molding (www.qualiformrubbermolding.com) and Custom Rubber Corp. (www.customrubbercorp.com) both manufacture rubber injection molding.
What is the difference between extrusion blow molding and injection blow molding?
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.
Application of EVA injection molding process?
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.
What are some facts about injection molding?
Injection molding is the manufacturing process for producing parts from thermoplastic and thermosetting plastic materials.
How does injection molding work?
Injection molding is a process in whih the material normally plastic,is injected into a mold to produce a componenet.
Where can I learn about plastic injection mold?
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.
How do I compare injection molding machines?
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.
