What main equipment should be used in the production of plastic ball?
(1) extruder.The monochrome ball can be extruded by a screw with a diameter of about 45mm.The double chromosphere USES two extruders with screw diameter of about 45mm.The length-diameter ratio is 20: : 1, and the compression ratio is (2~4) 1.
(2) the nose.Adopt the corner head, the head of the internal flow channel has a large compression ratio, the mouth part of the larger mold.
(3) the mold.The hollow ball mould is usually made of cast aluminum, the clamping insert is made of high quality steel after heat treatment, and the cavity is sandblasted.
