In recent years, sand 3D printing technology in various fields to show the unique application value, highly respected by the national support and promotion.

The foundry industry "14th Five-Year Plan" development plan, pointed out that by 2025, the use of 3D printing technology to produce more than 500,000 tons of castings; to achieve the demonstration of green modeling materials such as inorganic binder application; foundry sand recycling recycling reached more than 8 million tons; cultivate more than 200 green casting plant.

The Ministry of Industry and Information Technology and other three departments also jointly issued the "on the promotion of casting and forging industry high-quality development of the guiding opinions", which clearly put forward to promote the integration of die-casting molding, mold casting, sand 3D printing and other advanced technology to achieve the industrialization of the application.

Sand 3D printing application areas

Sand 3D printing technology is widely used in aerospace, ships, pumps and valves, automotive (new energy), energy power (electrical), industrial machinery, rail transportation and other fields.

In the aerospace field, 3D sand casting technology can be used to manufacture engine parts, spacecraft structural parts, power units and other important parts. Can effectively solve the oversized, multi-dimensional surface, complex structure of the workpiece molding problems, in small quantities of large size mold manufacturing and special industry mold iterative upgrading research and development has the advantages of the traditional manufacturing process can not be compared.

In the field of ships, 3D sand casting technology can be used to manufacture high-quality hull parts, improve the performance and safety of ships.

In the automotive field, 3D sand casting technology can be used to manufacture complex automotive components, such as engine parts and transmissions, etc., to improve manufacturing efficiency and precision.

In the field of energy and power, 3D sand casting technology can be used to manufacture large-size pressure-resistant complex cavity structure parts, large thin-walled lightweight parts and so on.

Sand 3D printing to make up for the shortcomings of the casting industry

Traditional casting methods face many challenges, for example: the mold manufacturing process is cumbersome and time-consuming, while sand 3D printing through the software design of sand and sand core, and directly print, simplify the manufacturing process, shorten the production cycle.

Sand 3D printing technology can produce smooth, accurate and complex shape and structure of the sand mold and sand core, overcoming the traditional casting mold manufacturing in the shape and structure of the limitations, providing more innovative possibilities, while the casting defects are less, improving product quality.

Large castings batch customization using traditional processes, there are high cost of mold opening, long cycle time and other issues, sand 3D printing technology can be flexibly designed and modified according to the need to save time and cost of mold opening, improve production efficiency, and be able to meet the needs of customer customization and market diversification.

In addition, sand 3D printing also helps to improve the production environment, reduce labor intensity, promote the foundry industry to digital, intelligent transformation, help industrial upgrading, realize the green development of the foundry industry.

CC sintered ceramic sand & 3D printing casting

CC sintered ceramic sand is a kind of artificial casting sand, in recent years is widely used in sand casting, with high refractoriness, low thermal expansion, high degree of sphericity, high recovery rate. Among them, CC-3 sintered ceramic sand is mainly used for sand 3D printing.

CC-3 advantages

1. High molding strength, good air permeability, good filling;

2. Reduce the amount of post-processing of castings, casting surface is more polished;

3. High precision of sand core printing, high dimensional accuracy of castings;

4. High recycling rate;

5. Applicable to high-end steel castings, complex castings and castings with high precision requirements.
