How to investment casting in Mulan MFG?

Strictly abide by 10 casting procedures and never cut corners.

According to product requirements and shape structure, create a design plan for the cavity of a high-strength metal mold with a smooth surface, and simulate the production process to optimize the quality and stability.

Use high-precision cnc machining center to engrave the designed mold cavity in hard aluminum alloy, including products with very complex structures.

Use high-pressure equipment to inject molten wax solution into the metal cavity to fix the mold and lock the sliding mold. After a few seconds of natural cooling, a complete wax model is obtained. Mulan MFG can rely on 3D printing to create a complete pull model, which is suitable for rapid prototyping and saves mold investment costs.

multiple wax molds are welded into a “tree”, allowing the metal solution to flow into the mold cavity in stages. Put the whole wax mold assembly into the ceramic slurry, generally divided into 7 times, and continue to dry to make the thickness at least 10mm.

Through high temperature, the wax in the wax mold assembly is liquefied to retain the complete ceramic cavity.

The molten metal solution is slowly introduced into the ceramic cavity. This process is critical to prevent the ceramic cavity from overheating and exploding or the flow rate is too fast to cause the product to have quality risks such as pores.

Destroy the ceramic cavity on the surface, just like eating an orange, and get the complete investment casting product inside.

The product is divided from the “tree”, and the surface is shot blasted and pickled for a long time to remove burrs and oxide layers.Make the product look more beautiful.

Carry out professional solid solution heat treatment on the product to increase product performance.

According to product design and use requirements, precise numerical control processing is performed. The minimum tolerance is ±0.01mm.

Advantages of investment casting services

Investment casting parts can select appropriate materials and mold design schemes according to the product, and flexibly respond to the risk of substandard products.

1. Precision casting services

Mulan MFG has the courage to make technological breakthroughs. It can manufacture 0.015kg small investment casting parts and perfectly create complex shapes. For many product designs, complex contour designs and smooth processing surfaces can be realized in Mulan MFG.

2. Perfect casting parts surface

The surface of a good investment casting product is smooth. This casting surface can be displayed directly outside the product, saving a lot of processing costs.

3. Precise details

Investment casting can create LOGO, text, symbols, slots, holes, etc. on the product body.

4. Low cost mold Tools

Compared with other metal processing and casting processes, the cost of investment casting molds is very economical, and practical, and rarely causes mold damage without complicated maintenance procedures, and usually uses soft materials such as aluminum alloys and uses advanced CNC machining Center, fast processing, the fastest can be completed in 2 days. It is a very cost-effective mold investment.

5. Multi-component synthesis

When your product requires a combination of multiple products, you need to pay a lot of labor costs and time. Investment casting can be combined into a finished product by bonding after the wax model is formed, saving you costs.

What is the investment casting services?

Investment casting services is also called lost wax casting services. It is a precision casting process. It is widely used in solid parts and complex hollow parts. It is suitable for metal parts made of various alloys. It is often used for castings with complex structures and demanding performance requirements. It is a very reasonable casting method for customized special tools.
Investment casting has a high degree of design flexibility and can easily cast black alloy products with holes, threads, grooves, and complex structures. And eliminate part of the secondary processing part, saving costs.

What is the difference with other casting processes?

1. Wax molds of investment casting products are formed in aluminum molds, which can create complex structures without affecting the flow of molten metal.
2. Metal castings can effectively remove excess air through the tree-shaped components during the casting process, and no air holes will appear.
3. The surface of the ceramic cavity is very smooth and air-permeable, which can ensure that the surface of the metal casting is smooth and free of pores after cooling.
4. Investment casting can replicate high-quality castings in large quantities with very high efficiency, and maintain a consistent appearance and smooth surface.
5. Different from sand casting and die casting, investment casting can use 3D printed wax patterns to manufacture rapid prototype casting parts.
