The twin-screw sandwich extrusion molding enlightenment (1) In addition to the extrusion output of the material in the two-cylinder cylinder, the twin-screw spiral can also be designed as a special single-turn, variable-diameter variable-pitch double-formed disc. The form is used to realize the extrusion of the material, rounding and forming, and the double forming disc is formed into a good example for the epitaxial application of the screw technology. (2) The parallel sandwich extrusion output of the two material cylinders (that is, the filling of the inner packaging to form the sandwich) is quite ingenious, and provides and creates a good design idea for the parallel casting spring floating ball sandwich forming design of the latter three cylinders. (3) The mechanism has more complicated transmission mechanism, requires more action of transmission and more coordination, and mainly forms dough products. It is unable to shape the semi-fluid material (softer) food in confectionery products. Cast-molded cast-in-place forming is carried out by means of a plunger (piston) extrusion using a skin and a filling, and the casting process is carried out by means of a specially designed casting device. Nylon conveyor belts can be seen from the above-mentioned sandwich classification, the traditional sandwich molding technology is mainly for pasta products, and the sandwich molding technology for fluid and semi-fluid materials in confectionery products is relatively weak, and the water content of semi-fluid materials. More, softer, easy to stick, for such soft materials can only be casted, and put forward higher requirements for the structural design of the caster; the pouring design method is also inspiration for our subsequent design Give good reference and create conditions. fuel hose, fueling hose, rubber hose for fuel ICESUN VACUUM GLASS LTD. , https://www.icesunvacuumglass.com
