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.

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.

Compared to complete replacement, repair services can bring worn parts back into service at a lower cost. In addition, the screw barrel of the injection molding machine can replace the bushing in the worn part, while the extruder barrel usually replaces the entire bushing, so the maintenance cost is more expensive and not cost …

An injection molding machine is comprised of four main components: the base, the hopper, the barrel, and the clamping unit. There are also smaller components such as the nozzle, ejector pins, split mold, clamping unit, injection unit and hydraulic unit. The base holds all the other parts and the electronics needed to run the machine.

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 ...
