Sand preparation systems are integrated networks of mixers, dosing units, and conveyors that process base sand with binders and additives for the green sand casting and resin-bonded sand casting process.
Whether you are producing complex sand casting parts or heavy-duty sand casting steel components, the quality of your molding sand directly dictates the final surface finish and defect rate of your sand casting products.
The green sand casting process uses bentonite clay and water as binders — ideal for high-volume, economical production. The resin sand casting process uses furan, cold-box, or amine-cured binders for higher dimensional accuracy and complex geometries.
TES-SAN designs dedicated plant layouts for both processes, with the appropriate mixer series and dosing configuration for each application.
Mixer selection depends on plant capacity, resin system, and molding line geometry. TES-SAN's mixer family covers all major foundry requirements:
The automatic dosing system eliminates manual measurement errors, ensuring the exact binder-to-sand ratio is met for every batch. This drastically reduces chemical waste and prevents casting defects.
TES-SAN automatic dosing units operate with PLC control, inverter-driven pumps, and remote monitoring infrastructure — integrated seamlessly with existing sand casting equipment.
TES-SAN manages the complete project lifecycle: feasibility and engineering design, manufacturing, installation, commissioning, and operator training — all under a single contract. Local spare parts supply and remote monitoring ensure uninterrupted production.
Founded in 1994 by Mechanical Engineer Galip Yarar in Konya, Turkiye, TES-SAN is one of Turkey's leading manufacturers of foundry equipment, sand preparation systems, and filtration systems.
Yes. TES-SAN designs specific plant layouts optimized for the moisture and clay controls essential to the green sand casting process, alongside resin-based applications.
By ensuring precise binder ratios every batch, the automatic dosing system reduces chemical consumption by 15-25% compared to manual processes, minimizing waste and casting defects.
Absolutely. TES-SAN can integrate individual units — such as a Rail Mixer or Automatic Dosing System — into your current foundry infrastructure to boost immediate capacity.
TES-SAN systems support iron, steel, and ductile iron foundries for both sand casting steel and non-ferrous applications. All systems are engineered to meet CE standards.

The green sand casting process involves mixing silica sand with bentonite clay, water, and additives to create a moldable mixture. The mold is formed around a pattern, the metal is poured in, and after solidification the mold is broken away. TES-SAN green sand plant systems automate each stage.
Evaluate your required hourly throughput (tons/hour), binder system (green sand vs. resin), molding line type, and available floor space. TES-SAN engineers conduct a free feasibility assessment to recommend the optimal configuration for your sand casting foundry.
The primary methods are green sand casting, resin-bonded sand casting (furan, cold-box, no-bake), and shell molding. Each method has distinct binder requirements and surface finish outcomes. TES-SAN supplies sand casting equipment for all major methods.
Critical indicators include permeability, compressive strength, moisture content, and compactability of the molding sand. TES-SAN automatic dosing and mixing systems ensure these parameters are consistently maintained batch after batch.
