INJECTION SCREW KNOWLEDGE

Injection Screw Knowledge

A systematic guide to injection screw structure, compression ratio, L/D ratio, material selection, wear mechanisms and screw selection.

What limits do you have in selecting a spiral diameter for high viscosity materials?

What limits do you have in selecting a spiral diameter for high viscosity materials?

High viscosity materials increase both the plastic twisting and the flow resistance of injections, with double constraints on the diameter selection of the screws. The working prin…

How do you fix screw gel weights at different plastic density?

How do you fix screw gel weights at different plastic density?

The equipment ' s nominal gel mass is usually based on a reference material and cannot be directly equated with other resins. The working principles, selection conditions, common r…

Impact of a spiral diameter on plasticization capacity and cycles

Impact of a spiral diameter on plasticization capacity and cycles

Larger diameters usually provide higher screw volume, but the final plasticization is also subject to screw structure, velocity and material limitations. The impact of a screw diam…

Why is the screw's surface velocity more accurate than a single turn?

Why is the screw's surface velocity more accurate than a single turn?

The same per minute rotation on a different diameter spiral produces different circular surface velocity. The working principles, selection conditions, common risks and validation…

The calculation of the spiral diameter and the amount of time the material stays

The calculation of the spiral diameter and the amount of time the material stays

The duration of the stay of the material depends on the melting capacity of the drum, the amount of consumption per model, the plastic rhythm and the stoppage, rather than the fixe…

Measuring the impact of the ratio of the process to the spiral diameter on plastic stability

Measuring the impact of the ratio of the process to the spiral diameter on plastic stability

The ratio of the process to the diameter of the screw reflects the number of active snail lengths used per model. The measurement of the impact of the trajectories against the scre…

How the spiral diameter alters the injection pressure conversion

How the spiral diameter alters the injection pressure conversion

The hydraulic pressure or drive pressure shown by the equipment shall be converted to a melting side pressure through the effective area of the institution and the screw. The worki…

How does the cortex of the screws affect the return flow efficiency?

How does the cortex of the screws affect the return flow efficiency?

The extent to which a high-pressure molten is leaking along the prism is determined by the trajectorial gap between the diameter of the screw and the inner diameter of the drum. Th…

The big diameter screw needs and start risk

The big diameter screw needs and start risk

Large diameter increases in screw volume and potential plasticization have also significantly increased the area of stress, material resistance and rotation inertia. The working pr…

Why would a small diameter screw be better suited to a fine, fine plume?

Why would a small diameter screw be better suited to a fine, fine plume?

The small diameter screw corresponds to a smaller volume change at the same process resolution, which facilitates the control of micro-jet. The working principles, selection condit…
