Slag Cast Mould / Sow Mould

Customized Shell Mold Cast Sow Molds – Durable Gray Iron Molds for Aluminum Slag & Dross

At Y&J Industries, we provide precision-manufactured sow molds engineered for the safe and efficient handling of molten aluminum slag, dross, and excess metal. These slag cast moulds are purpose-built to catch and cast high-temperature by-products into solid blocks (“sows”) for cooling and metal recovery. Every sow mold is fully customized – produced strictly according to your drawings. The functional design remains entirely yours; we focus on precision manufacturing and practical manufacturability feedback to bring your design to a production-ready reality.

Shell Mold Casting in High-Grade Gray Iron – Made to Your Drawings

Most of the sow molds we produce are made via shell mold casting, using high-grade gray iron selected for its excellent thermal fatigue resistance and dimensional stability under repeated contact with molten aluminum. Y&J Industries is a Chinese manufacturer specializing in customized hot metal handling components through integrated casting, forging, and machining. For slag cast moulds, shell mold casting is the primary process. Simply provide your drawings (PDF, DWG, STEP, or other formats), along with required dimensions, specific gray iron grade if designated, and any additional treatment requirements. We replicate your part with high precision and strict quality control. While we do not offer mold design services, we can provide targeted feedback from a Design for Manufacturability (DFM) standpoint – helping optimize castability, draft angles, and wall thickness transitions without altering the functional intent of your design. Normally there is no fixed minimum order quantity; we adapt to your batch size, whether prototyping or full production runs.

Material & Treatment Options – Fully Tailored to Your Specification

Operators can match mold durability and performance to their specific process conditions by defining the material grade and post-cast treatment directly in their drawings – all produced to your exact requirements:

Standard High-Grade Gray Iron: For typical aluminum dross handling – cost-effective thermal endurance and consistent sow formation.

Specific Gray Iron Grades: Where your application demands enhanced high-temperature strength or hardness, we cast to the exact grade you specify.

Stress Relieving & Machining: We can apply stress relieving to minimize residual casting stresses, and machine critical mounting surfaces or interfaces per your tolerance requirements.

Protective Coatings: Upon request, apply surface coatings that further extend mold life in aggressive thermal cycling environments.

Regardless of which specification your drawing calls out, we manufacture each sow mold to your exact geometry, material, and quality demands.
