Mulan MFG is a reliable investment casting China company.
It actively provides a full range of precision casting services.

How to precision investment casting company working?

 

  • Internal mold design and manufacturing department.
  • Precise aluminum molds create precise wax models.
  • Wrap 7-10 layers of ceramic shell outside the model.
  • Dry for 7 days.
  • Dewaxing at 1000F-2000F temperature.
  • Liquid metal is filled into the ceramic cavity.
  • Strictly control the flow rate and temperature of the molten metal.
  • After cooling, carry out CNC automatic splitting of the shell.
  • Grinding, pickling, heat treatment.
  • Precision CNC machining into the final product.

As per product requirements and shape structure, investment casting companies create a design for the cavity of a high-strength metal form with a smooth surface, and recreate the production process to enhance the quality and security.

Utilize high-accuracy cnc machining focus to imprint the designed mold cavity in hard aluminum alloy, including products with extremely complex constructions.

Utilizes high-pressure equipment to infuse liquid wax solution into the metal cavity to fix the form and lock the sliding mold. Following a couple of moments of regular cooling, a complete wax model is acquired.Your investment casting company, Mulan MFG can depend on 3D printing to make a complete force model, which is appropriate for rapid prototyping and saves the costs.

Different wax molds are welded into a “tree”, allowing the metal answer to stream into the shape cavity in stages. The investment casting company puts the entire wax shape together into the ceramic slurry, by and large partitioned into multiple times, and keeps on drying to make the thickness essentially 10mm.

Through high temperature, the wax in the wax form gathering is condensed to hold the total earthenware cavity.

The liquid metal solution is gradually brought into the earthenware cavity. This cycle is basic to prevent the artistic cavity from overheating and detonating or the stream rate is too quick to even consider making the product have quality risks like pores. 

Destroy the ceramic cavity on a superficial level, very much 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.

The investment casting company carries out professional solid solution heat treatment on the product to increase product performance.

According to product design and use requirements of investment casting china and international standard, precise numerical control processing is performed. The minimum tolerance is ±0.01mm.

What is the investment casting services?

Investment casting services are likewise called lost wax casting services. It is an accurate casting process. It is broadly utilized in strong aspects and complex empty parts. It is reasonable for metal parts made of different composites. It is regularly utilized for castings with complex constructions and requesting performance requirements. It is a truly sensible  casting technique for unique instruments. Investment casting has a serious level of plan adaptability and can undoubtedly project dark alloy products with holes, strings, notches, and complex constructions. Furthermore, eliminate part of the auxiliary handling part, saving expenses of Investment casting china and international clients.

What is the difference with other casting processes?

  1. Wax molds of investment casting products are shaped in aluminum molds, which can make complex constructions without influencing the progression of liquid metal. 
  2. Metal projecting can viably eliminate abundance air through the tree-formed parts during the casting process, and no air openings will show up. 
  3. The surface of the ceramic cavity is extremely smooth and air-porous, which can guarantee that the outer layer of the metal projecting is smooth and liberated from pores in the wake of cooling.
  4. Investment casting can replicate top notch castings in huge amounts with exceptionally high effectiveness, and keep a reliable appearance and smooth surface. 
  5. Different from sand casting and die casting,investment casting  can utilize 3D printed wax examples to produce fast prototype projecting parts.

Advantages of investment casting?

  • Low-cost investment casting mold.
  • Can manufacture precise and complex parts.
  • High-efficiency automatic Investment casting process.
  • Excellent surface finish.
  • Greater freedom of design for casting parts.
  • One-stop metal investment casting services
