Products require machining and polishing

Stainless steel is not just for aesthetics; it truly excels in corrosion resistance and wear resistance, especially in high-frequency use and humid environments, where its stability far surpasses from ordinary metals. 304 stainless steel is also a commonly used standard in catering equipment, as it is less prone to odor residue and easier to clean.

Stainless steel castings, with their three core advantages of corrosion resistance, high strength, and high-precision forming, have become an irreplaceable key technology in high-end manufacturing. Despite the challenges of complex processes and high costs, their reliability in extreme environments and adaptability to complex structures have secured their important position in industries such as aerospace, medical, and energy.

The types of stainless steel surface treatments that our company can provide are as follows:

1. passivation

Passivation is a method of transforming the metal surface into a state that is not easily oxidized, thereby slowing down the corrosion rate of the metal.

2. electropolishing

Electropolishing, also known as electrochemical polishing, anodic polishing, or electrolytic polishing (especially in the metallography field), is an electrochemical process that removes material from a metallic workpiece, reducing the surface roughness by levelling micro-peaks and valleys, improving the surface finish.

3. Mirror polishing

Mirror finishing/Polishing is a processing and finishing method for polishing the surface of a workpiece into a mirror-like surface.

4. brushed finish

Brushed finishing is a surface finish process involving the mechanical polishing of metal surfaces using a wire brush or an abrasive pad to create a texture in a specific direction.

5. Vibratory Polishing

Vibratory finishing is a type of mass finishing manufacturing process used to deburr, radius, descale, burnish, clean, and brighten a large number of relatively small workpieces.

Technical Standards and Quality Control of Stainless Steel Precision Castings

Mechanical Property Standards

The mechanical property standards for stainless steel precision castings involve multiple indicators such as tensile strength, yield strength, and elongation. Taking 304 stainless steel as an example, its tensile strength is generally not less than 515 MPa, its yield strength is usually not less than 205 MPa, and its elongation after fracture is generally not less than 40%.

Dimensional Accuracy and Surface Quality Standards

The dimensional accuracy and surface quality of stainless steel precision castings are important indicators for measuring their quality. Different tolerance ranges and surface roughness standards are specified according to the specific application and design requirements of the product. For general industrial stainless steel precision castings, the casting linear tolerance may be controlled at around ISO-8062-CT4-6 grade; in terms of surface quality standards, obvious defects that affect product performance and appearance are not allowed, such as porosity, sand holes, and shrinkage cavities. Surface roughness can reach Ra3.2-6.3.

Frequently Asked Questions and Answers

Question 1: What are the main advantages of stainless steel precision casting process?

Answer: The main advantages of stainless steel precision casting include high dimensional accuracy, high surface quality, minimal or no machining, and the ability to cast complex shapes and high-temperature alloy castings.

Question 2: How to control the dimensional accuracy and surface quality of stainless steel precision castings?

Answer: Controlling the dimensional accuracy and surface quality of stainless steel precision castings requires adherence to strict technical standards and quality control procedures. Through precise mold design, advanced casting processes, and rigorous testing methods, it is possible to ensure that the dimensional accuracy and surface quality of the castings meet design requirements.

FAQ

Q: Do you sell this kind of product directly?

A: No, all of our products are custom manufactured for our clients.

Q: What will you do if I have a request for similar products?

A: First of all, our engineers will evaluate the project and tell if it is suitable for us. They will discuss more details with you to know the project better, and then we will work out a reasonable manufacturing solution and its cost. And then submit it to you. After we agree on all the terms, we will start with a contract for molds and sample making, and then the mass production after samples get approved.

Q: How do you make out the qualified products for us?

A: After molds get ready, we will supply samples for your approval. And if there is any problem with the samples, we will modify the molds and re-make samples for your confirmation until the final qualified products get approved.

Q: What about the lead time?

A: It depends on the quantity and our production schedule. Generally speaking, for most of the products, molds could be finished within 30days. And the mass production order could be finished within 25-30days.

Q: What about the packaging?

A: The packaging method depends. Usually, cartons and plywood pallets are primary options. And other packaging methods like plywood boxes, steel pallets are also available.
