Mineral Casting, sometimes referred to as granite composite, polymer-bonded mineral casting, artificial granite (AG) or epoxy granite, is a construction of material that is made of epoxy resin combining materials such as cement, granite minerals, and other mineral particles. During the mineral casting process, materials used for strengthening the construction such as reinforcing fibers or nanoparticles are added.

The materials that are made from a mineral casting process are used to build machine beds, components as well as high precision machine tools. To this end, the application of these materials can be seen in multiple industries such as aviation, aerospace, automobile, energy, general manufacturing, and engineering where precision is of major concern.

Besides the construction of synthetic materials, mineral casting as a metalworking process manufactures the iron-carbon alloys which contain a higher percentage of carbon in composition compared to a conventional iron casting process and therefore the casting temperature is lower than the traditional iron casting process because the material has a relatively lower melting temperature.

Basic Components of Mineral Casting

Mineral casting is a process of material construction that combines a wide range of ingredients to produce the end material. The two primary components of mineral casting are the specially selected minerals and the binding agents. The minerals that are added to the process are selected based on the requirements of the end material. Different types of minerals bring about different properties; with the ingredients combined, the end material is able to possess the characteristics of the ingredients it contains.

A binding agent refers to the substance or material used to form several materials into a cohesive whole. In other words, the binding agent in a material construction process serves as the medium that pulls the selected ingredients together to form a third material. The substances used as a binding agent include clay, bitumen, cement, lime, and other cement-based materials such as gypsum cement and magnesium cement, etc. The material used as the binding agent in a mineral casting process is usually epoxy resin.

Epoxy Resin

Epoxy is a type of plastic that is made by the reaction of multiple chemical compounds. Epoxy resins are used in a wide range of industrial applications for they have excellent toughness as well as strong adhesion and chemical resistance. Because of these specialized properties, epoxy resins are used primarily in building and construction applications as adhesives to combine materials.

Epoxy resins are known as structural or engineering adhesive because they are used heavily in making construction materials such as walls, roofs, and other building materials where strong bonds to a variety of substrates are required. As technology advances, epoxy resins are used not only as a binder for construction materials but also as the binding agent in the material industry to construct high-quality materials for industrial use.

Advantages of Mineral Casting

Mineral casting can be used for the production of materials for modeling, lightweight construction, bonding, and protection of machinery. The process for complex composite parts production is precise and delicate so that the end products can meet the requirements of the specific applications. Depending on the materials that are involved in a mineral casting process, the end products are constructed and equipped with the desired properties and characteristics for their job.

Better Physical Properties

Mineral casting is able to secure the geometric position of the individual machine elements by means of absorbing the static, dynamic, thermal, and even acoustic forces. It can also be highly media-resistant to cutting oils and coolants. The force damping capability and chemical resistance of mineral casting make material fatigue and corrosion less of a concern to the machinery parts. Having these features, mineral castings are an ideal material for manufacturing molds, gauges, and fixtures.

Higher Functionality

In addition to the characteristics a mineral casting can possess granted by the minerals it contains, the casting environment also offers some advantages to it. The low casting temperatures combined with innovative precision and bonding technologies produce precise machine components with high functionality and an excellent level of integration.

Why us

FRH uses the top-quality black granite in the world to make the precision granite surtace plate with stand.
Our superior black granite has the extremely low coefficient of water absorption, so it can minimize the possibilty of your precision gages rusting while seting on the plates. This black granite creates little glare resulting in less eye strain for individual using the plates.
We have chosen our superior black granite with the specific intent of keeping thermal expansion to a minimum.

Custom requirements
The custom option is available.
UFRH can make the granite plate according to your specific requirements, we also can help you imporve the drawing for your project, including custom sizes, thicknesses. If you need to add holes, counterbores, threaded or solid stainless steel inserts, dovetail slots and t-slots to vour surface plate, we can do that as well.

All our granite products are processed and tested under the strict standard before delivery, the tolerance of flatness is 1.6 um.

Case

Our granite plates passed the test of Shenzhen Academy of Metrology & Quality inspection, HUANAN TEST, South China National Centre of Metrology, etc.

This is the 4m*3m granite mechanical component of rail detection equipment for CRRC Corporation Limited (CRRC)

We  won the tender of 8m*2.5m granite mechanical component of The Institute of High Energy Physics of the Chinese Academy of Sciences
