The selection of raw materials for resin sand has a great impact on casting costs. This has been recognized by the vast majority of the foundry machinery industry, because the quality of resin sand affects the addition and consumption of various materials on the one hand, and on the other hand Affects the quality indicators of castings. How to reduce resin sand casting costs? We should consider the following aspects. Resin sand raw sand
Resin sand raw sand is divided into ordinary resin sand, washed resin sand, scrubbed resin sand, etc. Since scrubbing sand contains very little mud, it can greatly reduce the waste of resin sand and should be preferred. . Next, choose water-washed resin sand, but never use untreated raw sand. The price of the scrubbing sand itself is not high, generally RMB/ to RMB/, but its freight is relatively high. When choosing tree sand, you must first follow the principle of choosing the nearest location. This can reduce expensive freight costs on the one hand, and ensure the supply of resin sand without affecting production on the other. Second, try to use raw sand with a low angle coefficient. At the same time, due to the different technical levels and equipment equipment levels of each scrub sand production enterprise, the quality of the scrub sand they produce is also different. Therefore, if possible, when determining to use resin sand, the scrub sand manufacturer should be inspected and inspected. Its technical status, equipment status, sand source status, etc., and discover the other party's sand quality control results. In short, in the process of selecting raw resin sand, it is best to reduce the production cost of resin sand to a minimum by making reference to other aspects of the problem through experiments and comparisons, while ensuring production and quality.

The resin used in resin sand is relatively expensive, generally around RMB/year, so it has a greater impact on the casting cost. At the same time, due to the manufacturer's The production equipment is uneven, and the quality of the resin produced also varies greatly. If you choose a resin of poor quality, it will not only affect the quality of the resin sand molding sand, cause an increase in casting waste, but also increase the amount of resin added. The direct result is an increase in casting costs. Therefore, the selection of resin sand raw materials cannot It is only determined based on the technical data provided by the manufacturer, and you should have an understanding of the production equipment, production process and quality control methods of the resin sand manufacturer, and try your best to inspect the various indicators of the resin yourself or ask relevant companies with a good reputation The inspection department may conduct inspections, or learn from the experience of similar manufacturers, or choose resin sand products from well-known large companies with good reputations.

Other raw materials
Other raw materials for resin sand include curing agents, coatings, adhesives, release agents, sealing mud strips, etc. These raw materials have a negative impact on the quality of castings. The impact is not the main one, but the impact on the cost of resin sand casting cannot be ignored. For example, the difference in the amount of curing agent added not only affects the production cost by affecting the production efficiency of special tools during the molding process, but also affects the material cost. Therefore, the principle of selecting other raw materials of resin sand is to consider not only its quality issues, but also its matching with the main materials, such as procurement and transportation convenience. In short, as long as the resin sand equipment is reasonably selected, has reliable performance, and operates normally, the raw materials are matched, the quality is stable, and the supply is timely, the production process parameters are reasonably formulated, and the tooling and equipment are guaranteed, self-hardening resin sand casting can control and reduce casting costs, giving enterprises bring development and benefits.

The industrial applications of resin sand blasting include paint film removal, coating removal, surface cleaning and conditioning. It has been proven by industrial applications to be faster and more environmentally friendly than chemical removal. The method causes less damage to the base. This technology can also be used to remove flash and burrs on electronic products, thermosetting plastic products and rubber products, clean molds, sensitive components and gold-plated parts. It can also be used as a paint remover, adhesive, reinforcing agent, waterproofing agent, and flame retardant. agents, etc., widely used in various fields.
