What are the requirements during the injection production with black masterbatches?

When using black masterbatch for injection molded products, the injection molding machine should be screw type to avoid uneven coloring caused by poor plasticization and mixing.

Increase the extrusion back pressure to improve the mixing effect of the screw and make the black masterbatch more evenly dispersed.

Advanced colors and porcelain colors must be achieved only when the mold is pefectly smooth and bright.

During the production process, if black masterbatch is found to adhere to the hopper wall, it is due to static. The hopper can be grounded to eliminate static electricity, which will not affect the process.
