Molding Clamp Tonnage & Pressure: Save 30,50% on Injection ...

The two halves of the mold are brought together by the injection molding machine, and the molten plastic resin is injected into the mold at high pressure. There is pressure to push the mold halves apart, so the machine must be capable of applying enough opposing pressure to hold them closed during the filling/packing/cooling phase of the process.

INEOS Polypropylene Processing Guide

The linear mold shrinkage of injection molded parts will vary from 0.008 to 0.025 inches per inch, depending on the particular resin, molding conditions, part design, part wall thickness, and direction of flow. Figure 1 presents the shrinkage of polypropylene versus wall thickness in injection molded parts. These data were obtained from many and

Clamp Tonnage: More Is Better...Right? | Plastics Technology

Melt viscosity is related to clamp,tonnage requirements, but MFI does not reliably correspond to actual melt viscosity in molding and cannot be compared accurately between resin types. For example, PC will always show high viscosity in molding, regardless of whether the MFI is 2 or 25 g/10 min.

How to Stop Flash | Plastics Technology

Clean off any plastic, dirt, or contaminants that could keep the mold from closing properly. Check the mold especially for bits of plastic behind slides and down in the pocket of the leader pins. After such housekeeping, if flash persists, check for parting,line mismatch with pressure,sensitive paper , which can reveal if the mold is clamping evenly along the parting line.

from 60 percent to 85 percent. PP resins are highly crystalline, but they are not very dense. PP resins have a nominal specific gravity range of 0.895 to 0.905 g/cm3, which is the lowest for a commodity thermo,plastic and does not vary appreciably from manufacturer to manufacturer. For polyethylene, the density and crystallinity are directly ...
