These are just some examples of common accessories in the field of mining machinery, in fact, there are many other types of accessories and parts that can be manufactured by wax mold precision casting technology depending on the ore processing process and equipment type. The specific product category and application scope will be determined according to the needs of customers, design requirements and the characteristics of mining equipment.

2. Investment casting, also known as lost wax casting, wax casting or precision investment casting, is a casting process for manufacturing complex shapes and high-precision parts. The process typically includes the following steps:

(1) Mold manufacturing: First make molds according to product design requirements. Molds can be made of metal materials (such as aluminum alloy, steel, etc.) or refractory materials (such as gypsum, ceramics, etc.). Molds are used to make wax molds.

(2) Wax mold injection mold: melted wax material is injected into the mold to fill the mold cavity and form a wax mold similar to the final product.

(3) Wax mold assembly: a number of wax molds are assembled together to form a complete mold assembly, including feeding system, pouring system, etc.

(4) Vacuum dewaxing: the wax mold is placed in the vacuum dewaxing equipment, and the wax material in the wax mold is melted and evaporated by heating and vacuuming, so that the internal cavity of the wax mold becomes a cavity.

(5) Smelting metal: smelting appropriate metal alloys, usually using electric arc furnaces, induction furnaces or argon arc furnaces and other equipment for smelting.

(6) Casting injection: the preheated mold assembly is placed in the casting equipment, and the molten metal is injected into the mold cavity to fill the entire internal cavity of the wax mold.

(7) Cooling curing: After the metal is cooled and cured, the mold assembly is removed from the casting equipment.

(8) Mold crushing: the cooling solidified metal parts are separated from the mold, and the mold is often broken by mechanical or chemical methods to obtain the final casting.

(9) Finishing processing: finishing, removing residual material, deburring and other processing processes on the casting to obtain the final product that meets the requirements.

Investment casting process is suitable for the manufacture of complex, high-precision, high-quality parts, commonly used in aerospace, aviation engines, automobiles, medical equipment, electronics and other fields. It enables the production of parts with complex shapes, small structures and precise dimensions.

3. Investment casting has the following main advantages:

(1) Complex shape: Investment casting can manufacture very complex shapes and structures, including internal cavities, thin-walled structures, internal and external threads, etc. Investment casting enables a higher degree of freedom and design flexibility than traditional casting processes.

(2) High precision: investment casting can obtain very high dimensional accuracy and surface quality, and usually can achieve high linear tolerances and surface finish requirements. This is due to the precision of the wax mold and the low thermal shrinkage and almost no porosity during the investment casting process.

(3) Excellent material properties: investment casting can choose a variety of metal alloys, including high temperature alloys, corrosion resistant alloys and high strength alloys. This allows investment cast parts to have excellent mechanical properties, wear resistance, corrosion resistance and high temperature properties.

(4) No processing: investment casting can directly obtain parts close to the final shape and size, reducing subsequent machining processes and material losses. This helps to reduce production costs and improve production efficiency.

(5) Mass production: Investment casting is suitable for mass production and can produce a large number of the same or similar parts in a relatively short time. This makes investment casting more economical and expandable in industrial production.

Overall, investment casting is a casting process suitable for complex shapes, high precision requirements and excellent material properties. It provides more design freedom, can meet the needs of different industries for high-quality parts, and has significant advantages in improving production efficiency and reducing costs.

4. Investment casting can be applied to manufacture various types of products, especially for parts with complex shapes, high precision and high quality requirements. Here are some examples of common investment casting products:

(1) Aerospace parts: Investment casting is widely used in the aerospace field, manufacturing a variety of engine parts, turbine blades, turbine disks, combustion chamber parts, gas turbine parts, etc.

(2) Automobile parts: Investment casting can be used to produce automobile engine parts, turbocharger parts, chassis parts, transmission system parts, etc. It can provide high-precision, lightweight and high-strength parts.

(3) Medical device parts: Investment casting can be used to manufacture medical device parts, such as artificial joints, dental implants, bone repair instruments, etc. These parts often have complex shapes and highly customized requirements.

(4) Industrial valves: Investment casting can be used to manufacture various industrial valves, such as ball valves, butterfly valves, gate valves, etc. These valves usually require high precision shape and sealing performance.

(5) Petroleum and chemical equipment parts: investment casting is widely used in the petroleum and chemical industry, manufacturing a variety of corrosion-resistant alloy parts, high-temperature alloy parts, pump bodies, valve bodies, etc.

(6) Electronic equipment parts: Investment casting can produce radiators, shells, connectors and other parts in electronic equipment to meet the requirements of high thermal conductivity and complex shape.

(7) Art and jewelry: Investment casting technology can be used to make art and jewelry, can achieve complex textures and details, to provide high-quality casting results.

These are just some examples of investment casting applications, in fact, almost any metal part that requires complex shapes, high precision, and high quality can be manufactured by investment casting. According to the specific application requirements, the appropriate metal alloys and process parameters can be selected to achieve the desired product.
