Steel Casting

Investment Casting is a kind of casting process. Some people call it "Lost Wax Casting" or "Precision Casting". It can also be said to be a special casting improved from ordinary casting. Its precision and surface finish are higher than Ordinary casting is much higher. In some places where the precision requirements are not very high, Investment Castings can be used and assembled directly. Even in some positions that require precise assembly, we can meet the required requirements through local secondary CNC Machining of the product, which can reduce the product's cost. Below are some of the investment castings we have done.

Metal Casting

SCZY committed to the production of stainless steel, carbon steel, alloy steel and copper and other Metal Casting parts, and also provides professional follow-up secondary CNC machining (for places with high precision requirements and direct casting cannot meet the requirements) and various surface treatments etc. Our Investment Casting Parts accuracy achieve CT4-6, surface finish Ra.1.6~3.2μm and the wall thickness can be reach 0.5mm. Our high-quality engineering team and quality inspection team ensure product excellent quality and in time delivery. We would be happy to provide a free quote for your upcoming project.

SCZY Precision Investment Casting Process

Our precision investment casting process is made through 48 processes, including product design, open a mold, wax injection, wax mold inspection, wax assembly, On the hook, cleaning wax mold, slurry coating ( it divided into fine slurry and coarse slurry, only one day do one step. it need repeat 7 times) to make a shell mold, air-dried and dewaxing in the slurry room, put the shell mold in a roasting furnace and burn it to about 1200℃，smelt the steel into molten steel, add auxiliary materials, and then pour the prepared molten steel into roasting In the good shell mold, a series of post-processing processes such as natural cooling, shell removal, shot blasting, large cutting, grinding, sand cleaning, acid soaking, sand blasting, quality inspection and repair, white washing, packaging, etc., until the qualified rough products is completed.

Support Custom On Demand

Our investment casting technology can be customized on demand. It not only meets the pursuit of customers' individual needs, but also provides a more flexible and efficient production method.

Advantage of Investment Casting Process

1. High precision accuracy

The dimensional accuracy of our precision castings can reach CT4-6 and the surface roughness can reach Ra.1.6~3.2μm, which can greatly reduce the machining allowance of castings, and can realize no-surplus manufacturing, thereby reducing production costs.

2.Available casting complex shape parts

It can make the investment castings with complex shapes and difficult to machining by other methods. The outline size of castings is as small as a few millimeters and as large as thousands of millimeters. The thinnest wall thickness is 0.5mm, and the minimum hole diameter is less than 1.0mm.

3. Metal materials are not limited

Materials such as carbon steel, stainless steel, alloy steel, copper alloy, aluminum alloy, superalloy, titanium alloy and precious metals can all be produced by precision casting. For alloy materials that are difficult to forge, weld and cut, precision casting is especially suitable for production.

4.High production flexibility and strong adaptability.

It can be used for mass production as well as small batch or even single piece production.

What Is Investment Casting?

Investment Casting also known as "Lost Wax Casting" and " Precision Casting". Investment casting usually refers to making patterns from fusible wax materials, coating several layers of refractory materials on the surface of the pattern to make a shell, and then melting the pattern and discharging the shell, so as to obtain a mold without a parting surface. The casting scheme that can be filled with sand after pouring after the roasted at high temperature. Since patterns are widely made of waxy materials, investment casting is often referred to as "lost wax casting". The shape of investment castings is generally more complex, the minimum diameter of the hole that can be cast on the casting can reach 0.5mm, and the minimum wall thickness of the casting is 0.5mm. In the investment casting parts production, some parts that were originally composed of several parts can be designed into integral parts by changing the structure of the parts and directly cast out by investment casting, so as to save processing hours and consumption of metal materials, and make the structure of the parts more reasonable.The weight of Precision Casting parts is mostly zero to dozens of cattle (from a few grams to more than ten kilograms, generally no more than 25 kilograms), and it is more troublesome to produce heavy castings by investment casting.
