Sr Foundry Provides A Range Of Casting Process Services
SR Foundry offers casting processes covering sand casting, lost foam casting, precision casting, and shell casting. Whether you need small-batch designs or large-volume customization, we are a reliable partner capable of delivering custom castings quickly and reliably.
Sand Casting
Sand casting is a process that uses sand to create molds for producing metal parts. It is suitable for various materials such as gray cast iron, ductile iron, and cast steel. With its flexible molding methods, sand casting can meet the production needs of parts of different sizes, complex shapes, and internal cavities.
Sand Casting
Lost Foam Casting
Lost foam casting is a casting process that uses foam molds for shaping. This process reduces the limitations imposed by traditional parting lines and is suitable for producing castings with complex shapes that require the integral molding of multiple parts.
Lost Foam Casting
Shell Casting
Shell casting is a process that uses coated sand to form a thin-shell mold on the surface of a heated mold, and then pours molten metal into it to produce castings. Shell casting is suitable for mass production of small to medium-sized castings with complex shapes and high precision requirements.
Shell Casting
Investment Casting
Precision casting usually refers to investment casting, which is widely used in pumps, valves, automobiles, energy and general machinery equipment. It is suitable for producing castings with rich details and complex shapes, and can reduce the amount of subsequent machining.

One-Stop Solution For Castings From Design To Production
Beyond just production, SR Foundry can advise you on suitable casting processes and the most suitable materials for the casting based on the drawings you provide. You provide the ideas, we bring them to life.
Drawing Review
Review your drawings, dimensions, and technical requirements to assess casting feasibility and identify potential manufacturing challenges.
Material Selection
We recommend suitable casting materials based on operating conditions, mechanical requirements, and your project budget.
Project Quotation
Prepare quotations based on material specifications, tooling requirements, order quantities, and finishing needs.
Tooling & Mold Preparation
Prepare patterns, molds, and cores according to the approved drawings and selected casting process.
Melting & Pouring
Control metal composition and pouring conditions to meet the specified material and casting requirements.
Cleaning & Finishing
Remove gates, risers, residual sand, and burrs to prepare castings for further processing and inspection.
Dimensional Inspection
We check critical dimensions and tolerances against approved drawings to verify fit and assembly requirements.
Mechanical Property Testing
We perform tensile and hardness testing as specified to verify the required material properties.
Visual Inspection
We inspect accessible surfaces for visible defects, cleaning quality, and compliance with agreed appearance requirements.
Protective Packaging
We select packaging and secure components according to their weight, shape, and handling requirements.
