Resin sand produced by resin sand production line is collectively referred to as sand, sand, core sand is called coated sand, also known as shell (core) sand. It was originally a thermosetting resin sand invented in 1944 by Dr. CRONING in Germany.

Resin sand casting is to mix raw sand and resin to form resin sand, which is driven into the mold cavity and molded by means of heating or catalyst, and then the molded nixin is put into the casting mold for casting.

Resin sand (plastic sand) is widely used by military, aerospace and other commercial companies to remove paint from large areas of metal surfaces. At the same time plastic sand is used for sandblasting technology of raw materials, it is suitable for sandblasting machine to use together, the technology is mainly from Japan, the United States and other developed countries, our country also slowly start to use the technology, the technology will bring you another experience in the field of material processing. (rubber factory, sandblasting machine factory, sandblasting machine factory, electronic equipment factory, automobile factory, electromechanical equipment factory, steel plant, silver factory, etc.)

Resin sand USES: workpiece surface cleaning, workpiece surface coating before the pretreatment, change the physical and mechanical properties of the workpiece, workpiece surface finishing.

Resin sand used in electronic products, thermosetting plastic products and rubber products to flash and clean the mold, the sensitive element and gilded parts, can be used as a paint remover, adhesives, strengthening agent, waterproofing agent, flame retardant, etc., widely for architectural decoration industry, transportation industry, the advertising industry, agriculture, electronics, foundry industry and other fields.
