Casting Services We Provide
We offer a full range of casting services, from prototype development to large-scale production.
As an accurate and repeatable casting method, die casting is ideal for high-volume production runs where consistency and speed are critical. We offer both high-pressure and low-pressure die casting, producing durable and dimensionally stable parts from aluminum, zinc, and magnesium alloys. This process is well-suited for complex geometries and thin-walled designs.
Investment casting delivers exceptional detail and surface finish, making it perfect for intricate components across industries. A wax pattern is created and then melted away when molten metal is poured into the mold. This method supports a wide range of materials, including brass and all types of steel, providing high precision with minimal machining required.
Gravity casting, also known as permanent mold casting, uses reusable molds that withstand indefinite use. This process ensures high accuracy and repeatability, making it a cost-effective choice for medium- to high-volume production. With proper mold care, parts can be manufactured again and again with consistent quality.
Sand casting is one of the most economical and flexible methods for producing metal parts. Depending on your project, we can provide green sand casting, skin-dried sand casting, dry sand casting, or no-bake sand casting. This process is well-suited for large components and short production runs, offering excellent design flexibility at lower tooling costs.
Advantages of Our Casting Service
Our casting service reduces material waste and machining time, making it highly economical for medium to large production runs. You get lower costs per part without compromising quality.
From thin-walled components to intricate geometries, our casting processes can deliver shapes that are difficult or impossible to machine alone. Many parts require little or no secondary machining.
We provide castings with tight tolerances and excellent dimensional stability. Combined with CNC machining, we ensure precision parts that meet the strictest specifications.
Our metal castings are stronger and more durable than plastic alternatives, offering excellent performance in high-stress and high-temperature environments. Options include aluminum, steel, iron, and copper alloys.
We offer a variety of surface treatments, including polishing, anodizing, powder coating, and plating. These finishes not only improve the appearance of your parts but also enhance corrosion resistance and longevity.
Our casting services comply with international standards, including ISO 9001 and IATF 16949. Every part undergoes a rigorous inspection to ensure reliable performance and consistent quality.

Custom Casting Considerations
When planning a custom casting project, there are several critical factors that manufacturers and sourcing managers should evaluate before selecting a supplier.
Production Run Size
The quantity of parts you require often determines the best casting process. Foundries specialize in different production volumes—some excel in low-volume prototype casting, while others are optimized for high-volume production runs. Identifying your needs early ensures that you partner with the right casting company.
Tooling and Cost
Tooling has a significant impact on lead time and total cost. While die casting may require higher upfront tooling investment, it becomes more cost-effective at larger volumes. On the other hand, sand or investment casting is ideal for smaller production runs with more design flexibility.
Industry Standards & Compliance
Different industries such as aerospace, automotive, or medical, require strict compliance with international standards. Working with a vetted casting manufacturer ensures that your parts are designed and produced according to the required certifications and safety standards.
Design Expertise
Successful casting projects rely on strong design support. Experienced casting factories can advise on draft angles, wall thickness, and cost-effective mold designs, helping to avoid expensive redesigns or production delays.
Material Selection
Material choice directly affects the strength, durability, and performance of your part. Common options include aluminum, steel, stainless steel, copper, zinc, magnesium, nickel, and specialty alloys. A qualified manufacturer can guide you to the most suitable material based on your application.
By carefully evaluating these considerations, manufacturers can achieve reliable, cost-effective, and high-performance castings tailored to their business needs.
