How does a screw diameter match the theoretical amount of glue?
The spiral diameter determines the effective area of the cylinder and the volume of the journey in units, which also indirectly affects the pressure, stay time and plasticization.…
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.
Is it true that special alien snails improve plasticization?
Alien snails may increase melting or mixing for specific materials by altering the current transect, diversion and cut history. The working principles, selection conditions, common…
Combined effect of mid-altitude structures of the screw on weight inertia and strength
The medium-altitude structure can reduce weight and turn inertia and can accommodate cooling lanes, but it weakens the effective bearing section. The combined effect of the medium…
Design elements of a screw cooling hole in the processing of hot and sensitive materials
The internal cooling hole regulates the core temperature of the screw and changes the mucous orientation and local heat accumulation, but should not replace the right structure. De…
Why is the cone of the end of the spiral the focus of the crack-resistant design?
The end of the screw, the end of the thread and the cross-section mutations are prone to stress concentration, which is a common starting point for reversing fatigue. The working p…
How to avoid a bridge and slide around a screwdriver feed mouth
The feed mouth area needs to allow the particles to fall into a spiral and to form a stable solid transport through temperature and friction conditions. The working principles, sel…
Impact of coaxial and straightness of the screw on the life of the material cylinder
The same-axis and straight-lineness determine whether or not the spiral is evenly balanced with the rim of the wheel and is the basis for avoiding unilateral friction. The effect o…
Why the screwdriver error caused the plastic cycle fluctuations
The error of the route alters the effective volume and axle-direction rhythm of the snails and creates a cyclical disturbance of the pressure. The working principles, selection con…
How the fresco width and cleavages affect leakage flows and wear
Plumb width affects carrying area, friction heat and leak pathways, and side-processing quality also affects material retention. The working principles, selection conditions, commo…
Impact of changes in the root diameter of the screw on the strength of the twister and the volume of the screwdriver
The root diameter determines at the same time the capacity of the core of the screw to carry the cross-section and of the snail, which is a direct trade-off between strength and de…
