This is pressure that is created during the return action of the screw after injecting material. The screw turns (augers) to bring fresh material into the heating cylinder. This material is placed in front of the screw and nudges the screw backwards. A buildup of pressure is created at the front end of the screw.

The injection molder is attached to the press using a simple adapter with set screws that I turned out of aluminum on my Gingery lathe.

Flow Lines. Description: Flow lines are streaks, patterns, or lines - commonly off-toned in color - that show up on the prototype part as a consequence of the physical path and cooling profile of the molten plastic as it flows into the injection mold tooling cavity. Injection molded plastic begins its journey through the part tooling via an entry section called a “gate.”

Nov 17, 2020 · By its very nature, plastic injection molding is a manufacturing process that creates a lot of pressure. 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.

The injection pressure must vary with the flow ability of the material. The typical value for injection pressure is between 2 to 8 tons per square inch (or 28,000~110,000 KPa). As a rule of thumb, 4 or 5 tons/inch^2 (55,000~69,000 KPa) can be used for most products.
