Coated Sand Mixer for Sand Molding and Casting

The M Series Coated Sand Mixer is a next-generation batch-type hot-box mixing system engineered specifically for shell molding processes, designed to uniformly coat silica sand with thermosetting phenolic resin under precise temperature control and initiate controlled pre-curing. It is widely used in the production of high-value shell cores for automotive engine blocks/heads, turbocharger housings, and precision hydraulic manifolds. Featuring modular design, intelligent control, ≥99% coating uniformity, and minimal resin loss (≤0.5%), the M Series delivers a fast cycle time of just 60–120 seconds per batch, making it the ideal solution for modern automated shell core lines.

Precise Temperature Control for Consistent Reaction
Combined electric + thermal oil heating system ensures ±2°C accuracy (120–200°C range), guaranteeing optimal resin flow and controlled pre-cure—eliminating premature hardening or uneven coating.

High-Efficiency Mixing for Uniform Coating
Proprietary dual-layer counter-rotating blades (main mixing + wall-scraping auxiliary) create 3D shear and dead-zone-free tumbling. Resin film thickness variation ≤3%, coating uniformity ≥99%—enhancing shell core strength and surface finish.

Smart Recipe Management, One-Touch Operation
PLC + HMI control system stores ≥200 recipes (sand weight, resin ratio, temp, time, etc.). Fully automatic operation with one-button start—minimizing human error.

Low Resin Consumption, Eco-Friendly
Sealed mixing chamber + high-efficiency atomizing nozzles achieve ≥99.5% resin utilization. Integrated vapor condensation unit reduces VOC emissions—compliant with green foundry standards.

Quick Cleaning & Maintenance
Mixing pot tilts fully open; blades feature quick-release clamps—cleaning or replacement completed in under 30 minutes, ideal for multi-product runs.

Automotive: Engine block/head shell cores, crankcases, intake manifolds
Turbo Machinery: Turbocharger center housings, turbine casings
Hydraulics: Multi-way valves, piston pump bodies, control manifolds
Precision Castings: Medical device brackets, aerospace small components
