Konter rotéierend Parallel Zwilling Schrauwen a Faass

Kuerz Beschreiwung:

The inner cavity of the parallel twin-screw barrel is designed with a double-hole through-hole structure, ensuring that the two mutually meshing screws rotate within a sealed space. As the core component of the extrusion system, its structural design directly determines the key process effects such as material transportation, mixing, melting, and evaporation.

Produit Beschreiwung

The inner cavity of the parallel twin-screw barrel is designed with a double-hole through-hole structure, ensuring that the two mutually meshing screws rotate synchronously or asynchronously within a sealed space. As the core component of the extrusion system, its structural design directly determines the key process effects such as material transportation, mixing, melting, and evaporation.
