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.

Injection molding courses in Toronto?
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.
What is K value in PVC?
K Value is an indicator of molecular weight : K-57 is medium for injection molding,K-67 is medium-high for rigid extrusion, K-70 is higher for plasticized extrusion or calendering. K value relates to other ASTM indicators of molecular weight like Intrinsic Viscosity or Inherent Viscosity.
What is the Benefit of Plastic Injection Molding in Automotive Manufacturing?
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

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
What machnes do you used to make plastics?
Plastic is processed using different techniques like extrusion,blow molding,film blowing,sheet thermoforming,transfer molding,contact molding,compression molding,injection molding etc.
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.

where can I find injection molding ?
You can find injection molding on websites online. One such website I found online that has injection molding is http://www.plasticstoday.com/imm.
What are the main differences between injection molding and blow molding?
In injection moulding the polymer is moltern and 'injected' into a mould. in blow moulding the polymer is as a sheet or as a parison that is pushed into a mould by air. I guess the main difference is injection moulding fills the mould with solid parts where as blow moulding just creates a thin surface

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.
