EMM091-4 three-component elastomer casting machine

1. Introduction

EMM091 series elastomer casting machine, a new kind of machine, develop on the base of EMM087series, has reached to the world level. EMM091-4 series elastomer casting machine suits pours precisely two to three component PU systems,such as a prepolymer add a high melting point of the chain extender (such as MBOCA); a prepolymer plus a chain extender diols (found in MDI cast elastomer systems) or a polyol, a diisocyanate and a chain extender (one-step casting MDI, MDQ system elastomers ).

2. Applicable Viscosity

A (Polyols or prepolymer ): ~4000mpa.s (45°C-100°C)

B (MDI/MDQ or prepolymer ): ~4000mpa.s (45°C-100°C)

C (when a chain extender alcohols): ~500mpa.s (45°C)

C (when MOCA): 10~1000mpa.s(130°C)

3. Pouring output

Output: 5000-25000g/min

The pouring out will be different as result of raw materials’ density and mixing proportion.

As the same time, the standard three-component casting machine could increase another six injection heads at most. According to the product needs, it can add color, add catalyst (customers can choose according to their own needs). The casting machine by intelligent computer control.
