TRANSCRIPT
Practical values of melt correction factor for use in calculation of shot weight for some common plastics
Shot weight (g) = melt correction factor x swept volume in cc
The melt correction factor takes into account the change in volume at process temperature and also includes a factor for the flow characteristics of the shut off device on the end of the screw

THE De-Tech AT A GLANCE
Molding industry is growing steadily and the demand for good quality molded parts is increasing day by day. The requirements are always challenging and need expert solutions. In order to meet the required quality standards, the molding shop should have Injection Molding Machines that are versatile.
The molding machine is the single biggest investment in a molding shop that naturally gets focus. In the changing business environment the molder who molds commodity plastics today, may have to mold high end, precise engineering plastics tomorrow. In addition to the above, the dynamic market situation forces the molder to be globally competitive. The selling price of the molded part is getting reduced day by day, hence the molder needs a really versatile machine which is also expandable as and when the need arises. Ideally the machine should be Fast & Precise, with Proven Mold Safety, Flexible and offering a Low Operating Cost.
