This ratio is typically between 1.5:1 and 4.5:1. Some polymers simply run better on screws with a 2.5:1 compression ratio, while other materials process better on screws with a 4:1 compression ratio. Often so-called general purpose (GP) screws with a ratio of about 2.5-3:1 are employed which are suitable for a wider range of materials.

Injection Capacity Calculator For Injection Molding Machines

Knowing the shot weight of an injection mould tool is the first step in selecting a suitable screw and barrel assembly. Use the first calculator below to find the shot weight of an injection mould tool. The next step is to find a screw and barrel assembly that has the right capacity for the shot weight so that quality parts can be made.

IPLAS Products Injection Unit Calculations - Some basic

A normal practice is to begin molding at 6,000 to 8,000 psi and increase/decrease pressures as necessary while optimizing the cycle. L/D Ratio A critical factor involved in creating available injection pressure is the ratio of the length of the injection screw divided by the diameter (L/D).

Injection Molding Screws Are Critical To Part Quality

Selecting Injection Molding Screws. Using the right injection molding screws is crucial to making quality parts consistently and with maximum production output. To select the right screw, details of the particular part to be moulded must be known (that is, part material, weight, size and wall thickness).
