Can PET be used in extrusion blow molding?
Hey there,Blow molding is a manufacturing process by which hollow plastic parts are formed. In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding. The blow molding process begins with melting down the plastic and forming it into a parison or in the case of injection and injection stretch blow moulding (ISB) a preform. The parison is a tube-like piece of plastic with a hole in one end through which compressed air can pass.- noizyoyster.com
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.
Which sand used in CO2 molding?
green sand
What is the black molding above the wheel well called?
mudguard
What is the difference between injection molding in thermoplastics and injection molding in thermosetting plastics?
hi... EXTRUSION MOULDING means after the polymer granules are fed in hopper then it melts in barrel and go thru the rotating screw....a mould is fitted at the end of this assembly that continuously extrudes the polymer in a continuous long particular shape as pipe etc. this later can b cut at regular intervals if needed... while in INJECTION MOLDING as the molten polymer reaches the mold it takes the shape there cooled and then taken out frm the mold...if it consists of runners etc.then its separated and then the process agn starts... thus extrusion molding is a continuous process while injection molding is not. extrusion moulding is a continuous process, it gives a constant section.
What are some facts about injection molding?
Injection molding is the manufacturing process for producing parts from thermoplastic and thermosetting plastic materials.
What is the difference between thermo plastic and thermo setting plastic?
ThermoplastIc materials (such as polyethylene, nylon, etc ) are melt-processable, meaning that they can be heated to a melt (liquid) phase, forced into a mold, and then cooled to form a pre-determined shape. Typical processes include injection molding, compression molding, and blow molding. Thermoplastic materials can, many times, be potentially ground up and re-processed many times as there is no chemical reaction that occurs. Thermoset materials (such as epoxy, and some polyesters), on the other hand, undergo a chemical reaction and cross-linking of the polymer chains and can not be can't be ground up and re-processed.
How does resin transfer molding differ from compression molding?
Resin transfer molding is a smaller mold that will look great for smaller homes. Compression molding has a satied look which is great for stucco.

Toys?
Injection molding is a great way to produce toys at a low price. Injection molding is the most popular method of producing plastic toys.Plastic toys can be made from many different plastic materials. Polypropylene and thermoplastic are the most popular. Each material has its characteristics. The right material will make your toy last for many years.
What are the advantages of injection compression molding?
Not high in fact very low
What is thermoplastic injection molding used for?
Thermoplastic injection moulding is the process of injected hot plastic or glass into a mould to form a specific shape or product. Often used to make smaller parts for toys or machinery.

What products makes compression molding?
Compression molding starts by inserting plastic or gelatin into a heated mold. Once the material is heated to a pliable state, a hydraulic press compresses the pliable plastic against the mold, which creates a perfectly molded piece. This process is used mostly for manufacturing gears, dinnerwear and electrical parts.
