Applications
🔹 Medium to large injection moulding lines
🔹 Extrusion for film, pipe, cable, and sheet
🔹 High filler content blends including talc, wood flour, or flake
🔹 Precision blending for multi-layer and co-extruded products
🔹 Central material handling systems
Operation and Control
The WSB 1200 uses sequential dispensing into a weigh bin, ensuring accurate blending across multiple materials. The system allows for immediate changeovers, recipe management, and automatic error correction. Built-in vibration isolation and batch averaging algorithms ensure consistent dosing performance across variable material types.
Maintenance & Cleanout
Tool-free access, modular hoppers, and a built-in air gun enable fast cleanout and colour/material changes. Designed for operators with minimal training, the WSB 1200 is a workhorse that reduces downtime while maximising material yield.
