Take everyone to understand the characteristics and advantages of precision casting molds

The characteristics and advantages of precision casting molds:

Precision casting molds, also known as investment casting molds, have the following characteristics compared to other casting methods and part forming methods:

The dimensional accuracy of castings is high, with fine surface roughness values. The dimensional accuracy of castings can reach 4-6 levels, and the surface roughness can reach 0.4-3.2 μ m. It can greatly reduce the machining allowance of castings and achieve zero allowance manufacturing, reducing production costs

Castings with complex shapes that are difficult to machine using other methods can be cast. The contour dimensions of castings can range from a few millimeters to thousands of millimeters, with a wall thickness of 0.5mm and a minimum hole diameter of 1.0mm or less

Alloy materials are not limited: materials such as carbon steel, stainless steel, alloy steel, copper alloys, aluminum alloys, high-temperature alloys, titanium alloys, and precious metals can all be produced by precision casting. For alloy materials that are difficult to forge, weld, and cut, precision casting is particularly suitable for production. The production flexibility is high, and the adaptability is strong. It can be used for mass production, small batch or even single piece production

In summary, precision casting molds have the advantages of small investment scale, large production capacity, low production costs, simplified complex product processes, and fast investment returns. Therefore, they are in a favorable position in competition with other processes and production methods, and have a bright future.

Taking stainless steel shell embryos as an example:

The traditional mechanical beer pressing method involves pressing the shell embryo twice, with a processing cost (mold, beer pressing, tempering, materials) of approximately 3-5 yuan per piece. Using precision casting technology, the processing cost is around 1.2 yuan per piece, and a set of precision casting equipment can produce around 100000 to 150000 shell embryos per month

Application scope of precision casting molds:

It is applied to almost all industrial sectors, especially aerospace, aviation, shipbuilding, steam turbines and gas turbines, weapons, electronics, petroleum, chemical, nuclear energy, transportation, light industry, textile, pharmaceutical, medical equipment, instruments and meters, machinery, pumps and valves, sports equipment, household appliances, and has been widely used in tableware, tools, watches, jewelry, and hardware in recent years.
