ˇˇˇˇHaian Wanli Foundry Co., Ltd. is a privately managed enterprise for production and sales of high-quality ductile-iron castings, and it has self managerial import & export license. The company covers an area of 66700 square meters and has 23500 square meters of building area. Its total assets can be up to RMB 120 million yuan, and the fixed assets are 66 million yuan. Now, the company has 310 employees including 25 technical persons and 18 quality management persons. Annually, the company can produce more than 60000 tons of ductile iron castings, and has been conferred as the biggest production base for ductile-iron castings in Jiangsu province. In 2001, the company passed the certification of ISO9001 quality system. In 2007, the company also achieved the certification of TS16949 system.
ˇˇˇˇCurrently, the company has 95 sets of production machines, including 4 sets of 2-ton medium-frequency electric furnaces, 7 sets of 1-ton medium frequency electric furnaces, 1 line of advanced shell-molding processing line, 8 lines of sand-coated iron-mold processing lines, 1 line of 10t/h resin sand molding line, 4 sets of Z149S (Z148E) molding machines, 12 sets of Z8612 (Z8625M) core-shooting machines, 4 sets of Q384 (Q378) cleaning chambers, and 10 sets of heat-treatment furnaces.
ˇˇˇˇMeanwhile, the company also has more than 32 sets of various inspection facilities, including 1 set of direct-reading spectrometer (imported from USA, model SFQ), 4 sets of pre-furnace thermal analyzing instruments, 4 sets of ultrasonic flaw detecting machines, 1 set of digital-display large-scaled metallographic microscope, 1 set of electronic tensile testing machine, 1 set of 3-dimensional gauge, etc.
ˇˇˇˇWith the main production processes of shell-molding, sand-coated iron-molding, resin sand molding, clay sand molding, core-making with hot core-box, electric furnace melting, pre-furnace quick inspection, mechanical shot-blast cleaning, and other methods, the company can supply castings in various material grades including QT400-18, QT450-10, QT500-7, QT600-3, QT700-2, QT800-2, QT900-2. In recent years, we have developed a kind of ductile iron with high-strength and high-toughness, and has put this new material into stable production. In 2005, our advanced ADI (austempered ductile-iron) material has passed the appraisal of science & technical achievement from Jiangsu Science & Technology Bureau and won science & technical progress prize in Jiangsu province. Technology of this ADI material has reached international advanced level.
ˇˇˇˇMain products of the company include castings for engine-used ductile-iron crankshafts and camshafts. Furthermore, the company also can supply various castings for automobiles, trains, high-speed railways, solar energy, marine machinery, wind power, engines, compressors, and various industries including building machinery, textile machinery, printing machinery, food machinery, mineral machinery, etc.
