At present, the company is in a period of rapid development, and has become one of the largest domestic foundry manufacturers with advanced equipment, strong technical force, multiple varieties and mass production. It is known for its production of "thick and large-section ductile iron castings" and is in the leading position of the foundry industry. .
The company covers an area of 170,000 square meters. The total number of employees in the company is 1200.
The company has more than 140 sets of large and medium-sized production equipment, including advanced resin sand casting production lines, cupolas, induction electric furnace melting equipment and large-scale shot blasting machines, heat treatment furnaces and other post-processing equipment for castings; it has more than 70 testing equipment (sets) ), Also equipped with direct-reading spectrometers, infrared carbon and sulfur analyzers, mechanical performance testing machines, large horizontal microscopes and ultrasonic flaw detectors imported from Germany.
The company and Tsinghua University, Hunan University and other universities have jointly established a provincial enterprise engineering technology center. The company's casting technology center was identified as the provincial-level enterprise technology center in Zhejiang Province, and the "thickness and large section ductile iron template castings for injection molding machine" developed by the company was included in the national torch project.
The company's main casting products include large-scale wind turbines, large-scale diesel engines, large-scale injection molding machines, large-scale machining centers, and large-scale mining machinery. The annual production capacity is 200,000 tons, mainly ductile iron, gray cast iron and vermicular graphite cast iron. Among them, ductile iron grades QT350-20, QT400-18, QT450-10, QT500-7, QT600-3, QT700-2, QT800 -2, gray cast iron grades are HT200, HT250, HT300, and vermicular graphite iron grades are RUT300. The maximum wall thickness for the production of ductile iron castings is 1200 mm, and the maximum single piece casting weight is 160 tons.
The company has strong, fast-responding R & D and production capabilities.
