The difference between stainless steel cast and aluminum die cast:
Material properties
Stainless steel : Mainly composed of iron, chromium, nickel and other elements, it has high strength and hardness, strong corrosion resistance, and can be used for a long time in damp, acidic, alkaline and other harsh environments without rusting . Stainless steel has a high density, usually 7900kg/mm³, and is relatively expensive .
Aluminium alloy : Mainly composed of aluminium, copper, magnesium, zinc, silicon and other elements, it has a relatively low density of about 2700kg/mm³, is light in weight, has low strength and hardness, but has good plasticity and corrosion resistance . Aluminum alloys can be treated in various ways, including electrophoresis, painting, anodizing .
Processing technology
Stainless steel casting : usually sand casting or lost-wax casting, etc. Stainless steel castings have good machinability, can be formed by casting, forging, machining and other processes . Stainless steel castings maintain good mechanical properties and corrosion resistance at high temperatures .
Aluminum die casting : Formed by pressing molten aluminum alloy into a die using a die casting machine. Aluminum die-castings have high production efficiency and precision, suitable for mass production . Die-casting aluminum alloy surface treatment mainly includes electrophoresis, painting and anodizing, etc to enhance corrosion resistance and aesthetic .
Application field
Stainless steel castings : Due to their high strength, high corrosion resistance and good processability, stainless steel castings are widely used in chemical engineering, Marine engineering, food processing and other fields, especially in situations where high corrosion resistance and high-temperature stability are required .
Aluminum die castings : Aluminum alloy die castings are widely used in the automotive, electronics, construction and other fields due to their light weight, good formability and low cost, especially in products that require lightweight design.
All of our precision custom cast parts are made according to customer's design, our work flow chart is as belows:
100% customized production based on provided drawings
Break through the limitations of standard parts, support customers in providing 2D/3D drawings, samples or design concepts, and achieve flexible customization in full size, structure and process. From prototype development to mass production, it precisely replicates complex geometric shapes and functional requirements, especially excelling in the manufacturing of non-standard parts, irregular-shaped parts, and high-precision integrated components, addressing the pain point in the market where general products "cannot match special working conditions".
Performance Advantages of 304 Stainless Steel
Compared with ordinary cast steel or low-grade stainless steel, 304 material has outstanding corrosion resistance (resistant to acids, alkalis, salt spray, and organic solvents), high-temperature oxidation resistance (continuous temperature resistance up to 800°C+), and food-grade safety. It meets the requirements of harsh scenarios such as medical care, food processing, and Marine engineering, and its service life is 3 to 5 times longer than that of standard parts.
Rapid Response and small-batch flexible production
Equipped with a modular mold system and an agile supply chain, samples can be delivered 25 days, supporting small-batch orders ranging from 1 to 1,000 pieces. This avoids the drawbacks of traditional founters, such as high mold opening costs, long delivery times, and large minimum order quantities, significantly reducing customers' trial-and-error costs and inventory pressure.
Essential Differences from standard products
Most of the common castings in the market are fixed models, requiring customers to "compromise designs to adapt to existing products". However, our company, through our deep customization capabilities, ensures that the products are 100% in line with the equipment/process requirements of customers, building technical barriers in terms of corrosion resistance, precision life, and delivery efficiency. They are particularly suitable for replacing imported parts or upgrading traditional solutions.
1Q: Why choose 304 stainless steel for cast parts?
1A: Grade 304 offers superior corrosion resistance, high-temperature stability (up to 800°C), and compliance with FDA/ISO standards, ensuring durability in harsh environments like chemical, marine, or food-processing applications.
2Q: Do you support fully customized designs?
2A: Yes. We accept 2D/3D drawings, samples, or conceptual sketches, enabling bespoke geometry, tolerances (±0.01mm), and surface finishes (Ra 0.2-3.2μm) to meet unique operational requirements.
3Q: How do you ensure precision in cast parts?
3A: Combining investment casting (＞98% density) with CNC machining guarantees dimensional accuracy, while shot blasting enhances surface integrity and fatigue resistance.
4Q: What is the lead time for prototypes or small batches?
A: Prototypes ship in 25 days; small batches (1-1,000 units) within 5 weeks, leveraging modular tooling and agile production to avoid traditional foundry delays.
5Q: How is quality verified?
5A: Each batch undergoes full-dimension inspection, backed by ISO 9001 certification and material traceability (AMS 5355).
