Pengetahuan industri
The first step in the manufacturing process is selecting the right materials. Ductile cast iron is created by adding specific alloying elements to the molten iron, which helps to produce its characteristic nodular graphite structure. The primary material used is pig iron, which is a high-carbon iron alloy, combined with other materials such as magnesium, copper, and silicon to impart the desired properties. The addition of magnesium is particularly crucial, as it causes the formation of spheroidal graphite in the cast iron, giving it ductility and enhancing its mechanical properties. Yancheng Longwan Machinery Co., Ltd. uses advanced induction furnaces, specifically their 1.25T medium-frequency electric furnaces, to melt and alloy the iron. These furnaces offer excellent temperature control, ensuring a consistent melt and proper alloy composition. The careful selection of materials and alloying ensures that the ductile cast iron parts produced will meet the high strength and wear-resistance requirements necessary for agricultural machinery components.

Once the alloy is prepared, the next stage is molding, where the liquid metal is shaped into the desired component forms. Yancheng Longwan Machinery Co., Ltd. utilizes advanced molding equipment, including a vertical sand-shot horizontal parting boxless shot-press molding line and an upper and lower sand-shot horizontal parting boxless shot-press molding line. These molding systems are capable of handling a wide range of part sizes, from small to medium, with precise control over the molding process. The sand-shot molding process involves creating a mold cavity using a mixture of sand and binder material, which is compacted under high pressure. The high-pressure shot-blasting ensures that the mold forms a consistent and durable surface capable of withstanding the high temperatures of molten metal. The sand is chosen for its ability to provide a smooth finish and the necessary strength to hold the molten iron without collapsing. Yancheng Longwan Machinery Co., Ltd. uses the vertical sand-shot molding line for smaller parts, which is capable of producing up to 120 boxes per hour. This line is ideal for the high-volume production of smaller agricultural parts such as brackets, valve bodies, and covers. For medium-sized parts, the company employs an upper and lower sand-shot horizontal parting boxless molding line, which is highly efficient and capable of producing up to 100 boxes per hour. These lines are ideal for manufacturing larger agricultural parts, such as housing components, axle parts, and structural elements. Yancheng Longwan Machinery Co., Ltd. employs experienced mold designers who work closely with engineers to develop custom molds for each specific part, ensuring the best possible fit and performance.

After the mold is prepared, the next step is pouring the molten ductile cast iron into the mold. The molten metal is carefully poured from the induction furnace into the prepared molds, taking care to avoid introducing impurities that could affect the quality of the castings. The pouring process is closely monitored to maintain the right temperature and consistency of the molten metal. Yancheng Longwan Machinery Co., Ltd. uses advanced monitoring systems to control the pouring process and ensure uniformity in the final casting. Once the molten iron is poured into the molds, it begins to cool and solidify. Cooling rates are carefully controlled to avoid the formation of cracks or other defects. Yancheng Longwan Machinery Co., Ltd. employs modern casting techniques to ensure the casting is sound and free from internal stress. For thicker or more complex parts, controlled cooling systems may be used to allow the casting to cool evenly and prevent warping.

Once the castings have cooled and solidified, they are removed from the molds and undergo a cleaning process. This is a crucial step to remove any sand residues, scale, or other impurities that may remain on the surface. Yancheng Longwan Machinery Co., Ltd. employs three cleaning shot-blasting machines for this purpose. These machines use abrasive media to blast the surface of the castings, effectively cleaning them while also improving their surface finish. Shot blasting not only removes contaminants but also ensures the surface is smooth and ready for subsequent finishing processes. The cleaning process is important for ensuring the dimensional accuracy of the part, as any surface irregularities can affect the machining and assembly of the component.

After cleaning, the castings are sent for machining, where they are processed to their final shape and tolerance. This is where Yancheng Longwan Machinery Co., Ltd. excels, as the company operates a number of CNC (computer numerical control) machines, including three CNC lathes and three traditional lathes. These machines are used for turning, milling, and drilling operations, which provide high precision and ensure that the parts meet strict tolerances. The machining process allows for the removal of excess material, fine-tuning the dimensions of the part, and creating precise features such as holes, threads, and surfaces that will be used in the final assembly. The company’s CNC machines are capable of handling complex geometries and fine tolerances, ensuring that even intricate agricultural machinery parts are produced to exact specifications. Each part is carefully inspected during the machining process to verify that it meets the required specifications. Yancheng Longwan Machinery Co., Ltd. maintains strict quality control procedures to ensure that every component is produced with the utmost precision, reducing the risk of defects and ensuring the parts' functionality.
