Find the optimum screw diameter for a given material and shot size. A widely recommended (but little understood) approach to screw sizing targets an injection stroke a stroke of 1 x the screw diameter (1D), to 3 x the screw diameter (3D) for the full shot size. The 1D to 3D approach is widely used by molding machine manufacturers, but the ...

Use a long-handled brush or cleaning tool to gently scrub the screw surface. Be cautious not to damage the screw while cleaning. Screw Pulling: For extensive cleaning or when changing material, consider pulling the screw out of the barrel. This allows for a more thorough cleaning and inspection of the screw and barrel interior.

For example, a screw with 9,698 cubic centimeters of volumetric capacity will process 8,825 grams of PS at 26,397 PSI. This is based on the material'smelt factor of 0.91 gram per cubic centimeter. Say you are molding PP, though, with that same screw. PP has a melt factor of 0.73 gram per cubic centimeter.

For PS the melt density is 0.945 g/cm 3 and for PP it is about 0.74 g/cm 3. This changes the ratio for our calculation; it is now 0.945/0.74 or 1.28. Now we need a minimum of 6.16 x 1.28 or 7.88 oz of shot capacity. We are still (just barely) within our 8-oz barrel capacity, but unfortunately Mr. Murphy is still lurking.

Obvious hardware differences between Extrusion and Injection: (1) L/D - Length divided by diameter (screw or barrel length /barrel inside dia. or screw outside dia.) in extrusion is normally 30:1 or greater; in injection molding 20:1 is still the normal l/d. The l/d in injection is further reduced as the screw reciprocates.
