Application of Alloy Steel Investment Casting

Agricultural Machinery: Alloy steel investment casting is commonly applied in creating metal components for various agricultural machines. It provides a cheap and effective way to produce durable parts for agricultural applications.

Construction Machinery: The civil construction industry relies on alloy steel investment casting technique to produce metal parts for various heavy equipments. Our high quality castings can help these machines to complete projects efficiently and effectively.

Food Processing Industry: In food processing industry, alloy steel investment casting is a preferred manufacturing process to make precise parts in alloy steel.

Marine Industry: When it comes to manufacturing parts for marine industry, alloy steel investment casting is a popular metal-forming technique used because it creates such a durable and high precision component.

Automotive Industry: Automotive parts need to be durable to maintain their quality through wear and tear and environmental conditions. Our alloy steel investment casting process allows for excellent corrosion resistance and high load bearing properties.

Aerospace Industry: Alloy steel investment casting is helpful in manufacturing thin-walled and lightweight components for aerospace industry. Simis can customize lot of high quality aerospace components using investment casting process.

Surface Finishing Options

Shot Blasted Finish

Shot blasting is the most common suface finishing method for alloy steel investment castings. It works by peening small steel balls onto the surface of each cast piece, and remove impurities and burrs to achieve a clean and smooth surface.

Machined Finish

Machined surface is required when some areas of alloy steel investment castings can not meet the drawing's dimensional tolerance or surface finish requirement. Simis has in hourse CNC machining capability to meet various machining operations.

Painted Finish

Painting is a cost effective surface finishing method for alloyn steel investment castings, which can prevent parts from rusting in the long term. A variety of colors are available by painting process.

Powder Coated Finish

Powder coating is a high-quality surface finishing way found on thousands of alloy steel investment castings. It provides a more durable finish than painting, but costs more.

Zinc Plated Finish

Zinc plating is the process of covering cast steel parts with a layer or coating of zinc to protect the substrate from corrosion. Besides, it can also help to improve the strength for better working performance.

Black Oxidized Finish

Black oxide is a conversion coating used on alloy steel investment castings. It results in a black, smooth surface finish, and improves corrosion resistance and wear resistance.

Alloy Steel Investment Casting Mechanical Properties Quality Inspection

To confirm the properties of the investment cast part are correct, mechanical testing is performed to approve the casting. We will make mechanical properties testing from next aspects:

Hardness testing	A non-destructive procedure that demonstrates the alloy steels machinability and wears resistance.
Tensile testing	A destructive casting quality test that provides ultimate tensile strength, yield strength, elongation, and reduction of the material test specimen.
Load testing	This test is performed on the entire casting lot to evaluate its casting quality and to verify that the cast part can carry (deflect) the required or specified structural load when applied. Pressure-containing parts can be hydraulically tested to a proof load or destruction maximum limit.

Welding Technology of Alloy Steel Investment Castings

Welding, joining and riveting processes are used to assemble parts or repair defects. The most frequently use way in our factory is:

Arc Welding

Uses an electric arc to join metals.

Brazing

Joins metals using a filler metal with a lower melting point than the base metals.

Soldering

Similar to brazing but performed at lower temperatures.

Assembling

Use rivets, screws, pins and some special parts to assembling several parts to make a small unit.

Q: What kinds of metallic alloys can be used in investment casting?

A: These alloys commonly include elements such as copper, magnesium, manganese, silicon, tin or zinc, each of which offers different casting characteristics. We use 300 series aluminum for many of our investment casting applications.

Q: What is alloy steel investment casting?

A: It is a precision casting process where alloy steel is used to create complex, high-strength metal parts by the investment (lost-wax) casting method.

Q: What alloy steel grades are commonly used for investment casting?

A: Although many different types of alloy steels can be used in the investment casting process. Grades like 4130, 4140, 4340, and stainless steels like 17-4 PH are frequently used.

Q: What is the pattern used in investment casting?

A: Investment casting, also known as precision casting or lost-wax casting, is a manufacturing process in which a wax pattern is used to shape a disposable ceramic mold. A wax pattern is made in the exact shape of the item to be cast. This pattern is coated with a refractory ceramic material.

Q: Which wax is used in investment casting?

A: Runner wax, also known as gating wax, has excellent flow properties. This type of wax is critical in ensuring the proper filling of molds. This helps with precise gating system formation. It has good adhesion to mold surfaces, ensuring leak-free gating channels.
