Ductile iron castings are widely used as a casting material due to their good mechanical properties and corrosion resistance, finding applications in mechanical manufacturing, the automotive industry, aerospace, and other fields. Selecting the appropriate processing technology for ductile iron castings is critical to ensuring their quality and efficiency.
Recently, a batch of high-quality cast iron products from Qingdao Zhaoyuqi Machinery Co., Ltd. have been successfully shipped and embarked on a journey to the European and American markets. This shipment not only demonstrates the company's strong competitiveness in the international market, but also receives high praise from customers for product quality, laying a solid foundation for the company to further expand into overseas markets.
What is sand casting? Sand casting is a process that uses sand as a casting material, bonds the sand to form a sand mold, and combines it with a sand core to form a casting mold; then pours, cools, and processes to obtain a casting. Sand casting is one of the most common casting processes because the molding materials used in sand casting are cheaper and easily available; the mold is simple to make and can be used for mass production of most raw materials or single-piece production of castings. We can use sand casting to complete steel, iron, aluminum, and most non-ferrous alloy castings.
Forging, as one of the essential processes in the field of metal fabrication, aims to transform metal billets into the desired shapes through heating and mechanical deformation. During the forging process, there are numerous details that must not be overlooked, as they directly impact the quality, performance, and reliability of the products. The following will provide a comprehensive introduction to the critical details that cannot be disregarded in the forging process.
1.Sand Casting: Pattern Creation: A pattern of the desired part is created from wood, plastic, or metal. The pattern is a replica of the final part and includes allowances for shrinkage and machining. Mold Making: The pattern is placed in a sand mold, and the sand is compacted around it. The mold is typically made of two halves, known as cope and drag. Pouring: The mold is opened, and molten steel is poured into the cavity created by the pattern. The steel solidifies within the mold. Cooling and Solidification: After pouring, the steel cools and solidifies. This can take several hours. Shakeout: The mold is broken apart, and the cast steel part is removed. Finishing: The casting may require additional machining and finishing to achieve the desired shape and surface finish.
In order to facilitate each user to choose to order casting products, steel casting manufacturers have changed their own production mode to the custom model, in order to allow each customer to choose the products they need, the casting products cast by steel casting manufacturers are widely used in the metallurgical industry, mechanical equipment and construction engineering and other enterprises, in order to meet the requirements of different customers for weight and performance, we will determine the appropriate casting process according to the drawings provided by customers. Tailor-made different types of casting products.
