Mineral Casting

Mineral Casting, sometimes referred to as granite composite or polymer-bonded mineral casting, 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 a 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 which 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 into the process are selected based on the requirements of the end material. Different types of mineral bring about different properties; with the ingredients combined, the end material is able to possess the characteristics with 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 the adhesives to combine materials.

Epoxy resins are known as the 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 the 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 makes 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.
