A screw on the injection molding machine can determine its service life and stability. For the screw on the injection cylinder, Taili Plastic Machinery always pays great attention to its assemble and require the worker to rotate the screw 3 circles and then loosen half a circle to the optional direction.
Screw is the basic fastener of injection molding machine. Its assembly process will directly affect the stability, speed, production capacity and other aspects of the injection molding machine, especially for the screw on the injection piston rod. Because of its complex stress, and long-term high temperature and vibration load, plastic deformation will easily occur, which will lead to a significant reduction in the strength of the screw. This will result in slight oil leakage, broken piston rod, coupling, and even affect the fracture of the pull rod and template.

Taili Plastic Machinery always pays great attention to the assembly and require the worker to rotate the screw 3 circles and then loosen half a circle to the optional direction. With this method, no obvious difference can be found by naked eyes when the assembly is completed. However, as a basic processing equipment, the difference will be easily seen under the long-term load. The reason is that the excessive pre-tightening force of the screw will make large plastic deformation, which will lead to long-term compression and final fracture of the screw. A half turn back will reduce the pre-tightening stress, so the screw is within the range of normal elastic deformation. What’s more, direct rotating the screw two and a half circles will result in insufficient pre-tightening force of the screw, which will cause the screw to loosen easily and make it unconducive to the long-term high-speed operation of the injection molding machine.
Taili Plastic Machinery always keeps in mind that what a good injection molding machine factory should do is to help improving the capacity and boosting the profits, rather than offer the similar products the customers need. This is also what Taili Plastic Machinery keeps doing.
