How to reduce the wear of injection molding machine screws
1, injection molding raw material temperature settings: each plastic, there is an ideal plasticizing processing temperature range, should control the barrel processing temperature, so that it is close to this temperature range.
Granular plastic from the hopper into the barrel, will first arrive at the charging section, in the charging section will inevitably appear dry friction, when these plastics are not enough heat, melting unevenly, it is easy to cause the barrel wall and screw surface wear increases.
Similarly, in the compression section and homogenization section, if the plastic melting state is disorderly and uneven, it will also cause increased wear.
2, screw speed setting: due to some plastics with reinforcing agents, such as glass fiber, minerals or other fillers. These substances on the metal material friction is often much larger than the molten plastic.
In the injection molding of these plastics, if the high speed into, in the increase of the shear force on the plastic at the same time, will also make the reinforcement accordingly produce more torn fibers, torn fibers contain sharp ends, so that the abrasion force is greatly increased. Inorganic minerals in the metal surface at high speed skating, its scraping effect is not small. So the speed should not be adjusted too high.
3, plastic in the debris: the production of pure raw materials may be relatively small risk, but now the enterprise in order to reduce costs, generally mixed in the raw material some of the sprues, due to some on-site management reasons, sprues in the crushing of some of the fine metal shavings are easy to mix, this is a great danger to the screw, so the general installation of magnets in the barrel frame, strict feeding management and monitoring.
