The mechanical properties of PRECOATED SAND are largely dependent on the sand type. It has an average granularity of 80 orders, bulk density of 2.5 grams per millimeter, angle of repose of 25 degrees, and fusing point of 95-105 degrees. The automatic sand pressure of penetrating core shooter is 0.35 Mpa and thermal curing time of two minutes.

The process of making the sand based on resin is technically advanced and extensively tested. It is the most accurate sand casting process in the foundry industry. Huttenes-Albertus offers a wide range of finished moulding materials and coating resins. Its Resital Precoated Sand, based on quartz sand, provides excellent flow properties and mould filling properties.

The chemical binders used in the production of PRECOATED SAND are mainly calcium, lithium, or zinc stearate. They are also commonly used in the production of other sand products. These binders are usually made of amine-hardened resins. The result of the process is a coating sand that has a higher melting point. Nevertheless, it is important to note that there is still a need to test the chemical binders used in the coating process to avoid harmful effects to the environment.

The production of PRECOATED SAND requires a high level of expertise. It is an effective way to improve the efficiency of your production by improving the quality of the sand. Besides, it is more efficient than traditional thermal core casing technology. This method does not result in smooth sintering. This is the reason why it has become the most popular choice among cement sand manufacturers. It is a cost-effective solution for a variety of concrete applications.

The chemical binders used in the manufacturing of PRECOATED SAND are added in small quantities and are not necessary for high-temperature concrete. The chemicals added to the sand before molding are used to harden the sand. This process is beneficial for the quality of the cast product. If it is hardened, it is durable and long lasting. Unlike uncoated sand, the chemical reaction is not affected by temperature. However, the sand must be kept at the same temperature during the production process to prevent the formation of cracks and other imperfections.

For a more rapid curing process, the resins used in PRECOATED SAND have been applied to the pre-coated sand. This resin allows the production of large amounts of a given product. In the case of sand, it is used to increase the strength of a concrete structure. If the coating is applied to a concrete product, the resin has the ability to withstand high temperatures.

A number of different applications have been developed using PRECOATED SAND. The technology involves a high-pressure sand injection machine and can produce molds and cores for concrete and plastics. It also has high surface quality and hygroscopicity. The benefits of using PRECOATED SAND are many. This technology has helped the industry to increase the efficiency of its manufacturing processes. This is one of the most cost-effective processes in the industry.
