Sand casting is an uncostly, versable, and friendly moulding technique widely used in metalworking. At our foundry, the sand process is best to manufacture decorative casting detailed parts, small to medium-sized casting pieces, and large volume orders.For decorative casting green sand casting technique is best moulding practice.

Molding is a metal equipment casting method that provides a desired design shape to the end product by pouring molten steel or other metal into a sand mold and letting it solidify in atmospheric temperature conditions. The products produced by sand molding are made in specialized factories known as foundries

• Iron ingots, pig iron, and other materials (fluxes like limestone and additives) are charged into the furnace.
• The charge is layered carefully to ensure efficient melting and proper chemical reactions.
• A gating system is set up, consisting of a pouring cup, runners, and gates that direct the molten iron into the mold cavity.
• These are structures placed in the mold to allow gases to escape and ensure proper filling of the mold cavity.
• Molten iron is transferred from the furnace to the pouring ladle.
• The ladle is then tilted or poured using mechanical devices to control the flow of molten iron into the mold cavity.
• After pouring, the molten iron inside the mold starts to cool and solidify.
• The mold is left undisturbed until the metal has completely solidified and cooled sufficiently.

Shot blasting is a surface treatment process used to clean, strengthen, or polish metal and other surfaces. It involves propelling small metallic or abrasive particles (shots) at high velocity against the surface of a workpiece.It plays a crucial role in improving the durability, appearance, and performance of metal components by cleaning, strengthening, or preparing surfaces for subsequent processes. Advanced technologies continue to enhance shot blasting efficiency and environmental sustainability in industrial applications.

Grinding is a machining process used to remove material from a workpiece by abrasion with a grinding wheel. It is commonly used for finishing operations to achieve high surface quality and precision dimensions.It is a fundamental machining process used to achieve precise dimensions, smooth surface finishes, and meet stringent quality requirements. Advances in grinding technology continue to improve efficiency, accuracy, and versatility, making it indispensable in modern manufacturing and tooling operations.

The powder coating process is crucial for enhancing durability and aesthetic appeal of cast iron ralings. Typically, a multi-layer approach is employed, starting with a primer to ensure strong adhesion and corrosion resistance. This is followed by an intermediate layer that provides additional protection against weathering and mechanical wear. The final topcoat, often a high-performance paint or powder coating, offers UV resistance and an attractive finish. This comprehensive coating system not only prolongs the life of the cast iron railings but also ensures they maintain their visual appeal in various environmental conditions.

At our facility, we take packaging seriously to ensure your cast iron balusters reach you in perfect condition. One key part of our process is stretch roll wrapping.

After the balusters are cleaned, checked, and bundled, we wrap them tightly using high-quality stretch film. This strong, flexible plastic film holds everything firmly in place, protecting the products from dust, moisture, and movement during transport. Each bundle or pallet is carefully wrapped by hand or with machines, ensuring the load stays stable and secure throughout handling, storage, and shipping.

This extra layer of protection ensures your order arrives safely—ready to install, display, or sell.

At our facility, to ensure the safe export of our cast iron balusters, we use heavy-duty, certified fumigated wooden boxes. Each box is designed to withstand the weight and shape of the products, with proper internal bracing to prevent movement during handling and shipping.

Before packing, every baluster is wrapped (usually with stretch film or protective padding), then securely placed inside the crate with foam, separators, or cushioning as needed. The boxes are then nailed or screwed shut and labeled clearly with handling instructions, product details, and export markings.

This packaging method offers excellent protection from impact, moisture, and rough transit conditions, making it ideal for international shipping by sea or land.
