Pig Mould / Ingot Mould

Customized Sand Cast Pig Moulds / Ingot Moulds – Heavy-Duty Low Alloy Steel Receptacles for Copper & Slag Solidification

At Y&J Industries, we deliver precision‑engineered solutions for metallurgical and smelting operations, designed to withstand extreme thermal and mechanical stresses while ensuring safety, efficiency, and durability. Our specialized product portfolio supports aluminum, copper, zinc, and vanadium processing, as well as large‑scale ladle handling and molten metal delivery systems. Within this scope, our pig moulds (also serving as ingot moulds or slag pots) are thick‑walled sand castings purpose‑built to cool molten copper or slag into standardized, easy‑to‑handle solid blocks. Every mould is fully customized – produced strictly to your drawings. You define the cavity geometry, overall dimensions, and material grade; we focus on precision manufacturing and can provide practical Design for Manufacturability (DFM) feedback to help bring your design reliably into production.

Sand Casting in Heat‑Resistant Low Alloy Steel – Made Exclusively to Your Drawings

Most of the pig moulds and ingot moulds we produce are manufactured via sand casting, using heat‑resistant low alloy steel grades selected for their ability to endure repeated thermal cycling without cracking or excessive distortion. Y&J Industries is a Chinese manufacturer specializing in customized hot metal handling components through integrated casting, forging, and machining. For thick‑walled receptacles like pig moulds, sand casting is the primary process, offering the flexibility to produce robust, one‑piece bodies with the heavy sections required for thermal mass and structural integrity.

To get started, simply provide your complete technical definition: 2D drawings (PDF, DWG), 3D models (STEP, IGES), along with your specified low alloy steel grade and any additional inspection or treatment requirements. We faithfully reproduce your design with strict dimensional control and process traceability. We do not offer mould design services; however, upon request we can review your design from a DFM perspective, offering localized suggestions on draft angles, wall thickness transitions, or stress relief cycles to improve castability and service life – without altering your functional intent. Minimum order quantity is not fixed; it depends on the specific material, process, and dimensions of your mould. We accommodate your batch size, from a single prototype to recurring production volumes.

Engineered for Controlled Cooling and Uniform Block Formation

This thick‑walled casting receptacle is designed to cool molten copper or slag into standardized solid lumps (pigs or ingots), ensuring safe handling and efficient downstream processing. Built from durable, heat‑resistant low alloy steel, it withstands repeated exposure to extreme thermal conditions while maintaining structural integrity. The design – provided by you – determines cavity shape, cooling characteristics, and block weight. By enabling controlled cooling and uniform shaping, the mould ensures consistent block formation, simplifies storage and transport, and supports recycling or further metallurgical use. Its robust construction reduces wear, minimizes maintenance, and enhances operational efficiency, making it an essential tool in smelting operations where reliability and consistency are critical.

Because every pig mould is manufactured exactly to your specification, it integrates seamlessly with your existing pouring, cooling, and stripping equipment.

Material Integrity – Your Grade, Fully Verified

Material selection for pig moulds directly impacts service life under cyclic thermal loading. You define the required heat‑resistant low alloy steel grade; we source with full traceability and provide mill test certificates documenting chemical composition and mechanical properties. Additional treatments – such as stress relieving to minimize residual casting stresses, or machining of critical surfaces to your tolerances – are applied strictly per your specification.
