A systematic guide to injection screw structure, compression ratio, L/D ratio, material selection, wear mechanisms and screw selection.
Low viscosity melts are more likely to flow back through small gaps and are more sensitive to sealing, shut-down response and size stabilization. The working principles, selection…
Antireverse carcino lags may occur in the direction of opening or closing, requiring a distinction between plasticization and injection performance. The working principles, selecti…
The screwhead and the anti-reverse components are the local flow lanes where the molten enters the front end from the measurement segment, and an insufficient area creates an addit…
The stopring ring end and the co-cooperating side form a critical seal and payload transfer area, and the plane level determines the continuity of exposure. The working principles,…
The screwdriver connects the screws to repeat axle impact, twist and temperature cycle, with the root being a typical fatigue sensitive area. The working principles, selection cond…
Transparent material is very sensitive to trace focus and residues, and screw-head flow requires continuous, smooth and easy to clean. The working principles, selection conditions,…
High-speed thin-wall plating is filled for a short period of time, and a larger proportion of the effective journeys can be delayed by the stopring of the loop. The effect of the v…
After the reversal of the wear and tear of the ring, part of the molten backwards when injected, and the volume of the actual entry to the moulds varied with pressure and viscosity…
The sealing test determines the leakage by controlling the front end of the screw, position and pressure and observing whether the screw is moving forward. The working principles,…
The sphere is in contact with the valves under pressure differentials and can form a clear sealed line, and the structural response is closely related to the routing. The principle…
According to the resin material, filling ratio, equipment model and product requirements, select a more suitable screw and barrel solution.
