The injection-molding process allows plastic manufacturer company to supply custom plastic name plates and components that might be too costly to form as intricately by utilizing traditional machining methods. Nubs Plastic Inc. is a full-service plastic Injection Molding Manufacturers facility. We provide solutions to various industries including medical, construction, agriculture, consumer products and more in the USA at competitive prices.
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)

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
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.
They're many vedio on youtube.You will be clear after seeing. If you're interested on molds, you can follow my google page "Sino-Mold Industrial Co.,Ltd" I always upload useful articles

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.
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.
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.
