Mineral casting

Project Introduction

The resin concrete machinery product is a new material that is synthesized from the waste granite and epoxy resin, fillers, reinforcing materials, and curing modification system by a special process, also called artificial granite. It is different from the artificial granite in the general sense. Artificial granite in the general sense can not be compared with the physical and chemical indicators, mechanical strength, performance and application. Artificial granite in the general sense is mostly used in the home improvement industry, and the ratio and manufacturing process are far from one another. My resin concrete machine tool products are used in the machine tool industry, PCB circuit board drilling rig industry, medical equipment industry, precision measuring instrument industry, and chemical, papermaking and other special requirements industries. The application fields of the products largely replace steel and cast iron, and the comprehensive properties such as product accuracy and damping are not realized by steel and cast iron. Due to superior product performance, it has largely broken through the application fields of steel and cast iron. Therefore, the future will be a materials revolution in which resin concrete products replace conventional steel and cast iron applications in certain fields.

Second, industry and market background

Resin concrete is also called artificial granite, also known as artificial stone. It is a new type of composite material. The modified epoxy resin and modified curing agent are cementing materials, and the granite particles are used as the base material, scientific grades are used to add reinforcing materials and accelerants, and are compounded by strict techniques. Compared with cast iron and steel, it has good vibration damping, corrosion resistance, low coefficient of thermal expansion, good electrical insulation, flexible design and manufacturing, short processing cycle, high reparability, high processing precision, and perfect combination with any material. advantage.

Due to the high strength of resin concrete and the incomparable advantages of many steels and cast irons, resin concrete materials have a wide range of uses. Internationally advanced countries such as Germany, Italy, the United States, Japan, and Switzerland have taken the lead in applying and achieving remarkable results. Resin concrete is widely used in high-precision mechanical components, high-precision measuring instruments, optical instruments, high-precision machine tools and other industries. To a certain extent, it is a new material that can replace steel and cast iron.

Internationally, the resin concrete machine tool basic accessories project began to be researched in the 1970s. At the end of the last century, Germany, Switzerland, Japan and other countries had already begun preliminary application and achieved unexpected results. China has also studied as early as the 1970s, but it has only achieved results in the last decade or so. Initially, resin concrete was only applied to the decoration industry called artificial stone. The application of resin concrete in the machine tool industry in China began in recent years. In recent years, with the breakthrough in the research of the comprehensive strength and various indicators of resin concrete, its application has also been greatly improved, especially in precision machinery. Components, precision machine tools, optical instruments, precision measuring instruments, filling of special steel structures, etc., have achieved very satisfactory results, filling the gaps in domestic resin concrete applications.

Resin concrete machine tool base components can largely replace steel and cast iron, but also in some high-precision processing and manufacturing applications, especially in corrosion resistance, retention accuracy, and vibration damping capability (with specific inspection reports And the physical and chemical data) is that steel and cast iron cannot be replaced. Resin concrete does not have any pollution or waste discharge during production.

Advantage

Excellent vibration absorption performance: The vibration absorption performance of ore casting materials is 6 to 10 times that of gray cast iron and steel.

Low thermal conductivity and good thermal stability: Mineral casting materials reflect very slowly on the change of external temperature. This improves the dimensional accuracy of the whole machine and ensures the processing precision of the machined parts. The chemical and mechanical stability is good and it can resist. Erosion of corrosive media, such as engine oil, corrosive solutions, acid solutions, and commonly used coolants, etc., at room temperature, does not require additional heating measures, low energy consumption, high casting accuracy, low internal stresses, and low internal shrinkage.

Great design tolerance:

Various mechanical parts are integrated, such as anchor bolts, hydraulic pipes, coolant pipes and grounding wires, which can be integrated and cast in castings for recycling. The ore casting material has a good chemical inertness, is easy to store and re-use, because the ore casting material can optimize the design and production, so the cost is reduced in many aspects such as machining, assembly and logistics, making it before the final assembly The cost is lower than that of the welded structure or the gray cast iron bed. Due to the adoption of a processing method in place, the production cycle of parts made of ore casting materials is shorter than that of castings and steel parts.
