तीस्रो लाभ भनेको अल्युमिनियमको कोटिंग र फिनिशिङ प्रक्रियाहरू सहजीकरण हो। अनायास नै यो धातुलाई विभिन्न रंगहरूमा पेंट गर्न वा एनोडाइज गर्न सकिन्छ, जसले गर्दा उत्पादनको आकारमा आकर्षण थपिन्छ। यसले उपभोक्ता बजारमा प्रतिस्पर्धालाई पनि सुधार्न मद्दत गर्छ।

The properties of sand make it an ideal choice for casting. It can withstand high temperatures, allowing it to accommodate molten metals like lead, which has a melting point of approximately 327.5 °C (621.5 °F). Additionally, sand is readily available and reusable, which minimizes costs and waste in the manufacturing process.

The Casting Process

(3) The influence of mould making on the linear shrinkage rate of castings: a. The influence of wax injection temperature, wax injection pressure and pressure holding time on the size of investment mold is obvious in the wax injection temperature, followed by the wax injection pressure, and the pressure holding time is guaranteed After the investment is formed, it has little effect on the final size of the investment. b. The linear shrinkage rate of wax (mold) material is about 0.9-1.1%. c. When the investment mold is stored, there will be further shrinkage, and its shrinkage value is about 10% of the total shrinkage, but when stored for 12 hours, the investment mold size is basically stable. d. The radial shrinkage rate of the wax mold is only 30-40% of the lengthwise shrinkage rate. The wax injection temperature has a far greater influence on the free shrinkage rate than the hindered shrinkage rate (the preferred wax injection temperature is 57-59℃, The higher the temperature, the greater the shrinkage).

Several casting methods can be classified under precision casting, including investment casting, lost foam casting, and ceramic shell casting.
