Fiberglass Resin Dough Sigma Mixer

The mixer is offered in Stainless Steel 316, Stainless Steel 304, or Mild Steel. Stainless-steel versions can be finished in matt or mirror polish as required; mild-steel units receive one coat of red oxide primer plus two coats of epoxy paint.

Models range from ASM-50 (approx. 50 L working / 80 L gross) to ASM-3000 (approx. 3000 L working / 3800 L gross). Motor power is available in general and heavy-duty ratings (e.g., 5–120 HP depending on model), with voltage customizable to local requirements.

Two counter-rotating Z-shaped (sigma) blades mounted in a W-shaped trough rotate toward each other at different speeds. This produces tangential mixing and kneading that combines bulk movement, stretching, folding, dividing, and recombining, plus shearing against the blades and trough walls for thorough processing of high-viscosity materials.

Discharge can be manual (hand-wheel operated tilting of the container) or automatic (hydraulic tilting). Additional options include bottom valves, an automatic valve discharge system, or a screw extruder for controlled product removal.

Yes. A jacket for heating or cooling can be fitted, complete with mineral-wool insulation and cladding. An optional blade-cooling arrangement further helps manage process temperature.

Tangential blades meet at the edges, typically rotate at different speeds (often a 3:2 ratio), and are preferred for higher-viscosity materials such as fiberglass resin dough and adhesives. Overlapping blades rotate at the same speed, suit lower-viscosity materials, provide faster material interchange, and produce less intensive kneading and shearing.

Available options include a liquid spray system, vacuum system, blade-cooling arrangement, screw extruder system, and automatic valve discharge system.

It features tangential Z-blades for intense shearing and uniform mixing, a minimum gap between the trough inner shell and blades to reduce product sticking, robust construction for heavy-duty use, and optional vacuum or spray systems that support efficient processing of sticky, high-density materials.

Key features include choice of SS 316 / SS 304 / mild steel construction with appropriate finishes, tangential Z-blades for uniform mixing, manual or hydraulic discharge, optional heating/cooling jacket with insulation, PTFE shaft sealing, minimal blade-to-trough clearance, and on-demand spray or vacuum systems.
