Product Description
Our premium coated sand features a sophisticated layer of resin, often referred to as resin coated sand. This exceptional product can be precisely customized to match a diverse range of sand recovery requirements, ensuring optimal performance for each application.
Experience the advanced process of shell type steel filling using dry sand. This involves strategically placing the shell type into a barrel and ingeniously surrounding it with steel balls or dry sand. This robust method is designed to enhance the reinforcement of the shell, ensuring superior structural integrity.
Discover a revolutionary casting technique where a mold is meticulously formed and molten iron is expertly cast. With steel pellets facilitating the cooling process, the result is faster cooling speeds, enhanced air permeability, and improved steel pellet recovery. This leads to reduced equipment investment, minimized die wear, and simplified mold changes, setting a new standard in casting efficiency.
Introducing the groundbreaking coated sand casting production line: a synergy of steel sand burial and rain sand adding technology. This cutting-edge solution redefines efficient and intelligent casting, setting new industry benchmarks.
In a world where the foundry industry is increasingly focused on green transformation and heightened efficiency, the coated sand shell casting production line from Sanzhuji stands out. It combines intelligent environmental protection with cost reduction and efficiency improvements. Featuring core technologies like steel sand burial filling, rain sand adding, and a water-cooled cooling bed, this production line provides disruptive solutions for modern foundry businesses.
Technical Highlights Analysis:
Steel Sand Burial Process: Utilizing innovative pre-burial and advanced three-dimensional vibration technology, this process achieves a remarkable 30% reduction in coated sand usage. It simultaneously boosts output by 10% and decreases scrap rates by 5%, all while maintaining impeccable dimensional accuracy and consistency in castings.
Rain Sand Adding System: This state-of-the-art system employs intelligent control over the sand adding process, significantly reducing manual intervention. It enhances sand filling uniformity and efficiency, catering seamlessly to sand boxes ranging from 1000×550×500 to 2000×600. Its versatility and adaptability make it ideal for multi-variety, small batch production.
Water-Cooled Cooling Bed: This innovative system, combined with a closed dust removal design, reduces cooling time to an impressive 1.5 hours. It not only accelerates the cooling of castings but also efficiently recovers heat, consuming just 20% of the energy compared to traditional methods.
Sanzhuji Intelligent Control: Harnessing the power of a Siemens fully automatic control system, this technology ensures precise management of the entire casting process, including pouring, box turning, and sand dropping. Achieving a rapid pace of 40 boxes per hour, a single line boasts a monthly production capacity of up to 3,000 tons.
Application Value:
Green and Environmental Protection: The entire production line is equipped with a closed dust removal and VOC catalytic combustion system, ensuring emissions meet stringent standards. This facilitates enterprises in seamlessly passing environmental protection audits.
Cost Reduction and Efficiency Improvement: Witness a 70% reduction in labor costs, with a compact floor space requirement starting at just 200 square meters. The investment return cycle is remarkably short, enabling production commencement within 60 days.
