The company operates an integrated 35,000 square meter production facility and employs more than 400 staff, including over 10 senior engineers and more than 50 senior technical managers, supported by a technology R&D center established in 2009 and a Zhejiang Province postdoctoral workstation. It is a member of the China Foundry Association and has been rated a National High-Tech Enterprise.

The company's core technology is silica sol precision casting applied to stainless steel, alloy steel, carbon steel, and copper/aluminum alloys, producing castings from 10 grams to 400 kilograms with annual production capacity exceeding 3,000 tons. Production is vertically integrated from mold design through silica sol casting to precision CNC machining (76 CNC machines, 20 machining centers, 11 lathes, capability up to 1,100mm diameter) and laboratory validation using a German SPECTRO direct-reading spectrometer. The firm has deployed additive manufacturing (ytterbium fiber laser direct sintering) and digital laser texturing for mold inserts with conformal cooling channels. Product categories span valve accessories, flowmeters and instrumentation, food machinery parts, water pump accessories, copper castings, and other precision castings serving petrochemical, hardware machinery, automotive, food processing, sanitary ware, medical equipment, water treatment, and instrumentation customers. Exports cover Europe, the Americas, Japan, and more than 40 countries.

The business model is B2B direct manufacturing and export with quote-based pricing determined by casting specifications, material, weight, complexity, and post-casting machining requirements. International certifications (ISO9001, IATF16949, GJB9001C, ISO14001, ISO45001, PED 2014/68/EU, ISO13485) and marine certifications (CCS, ClassNK, DNV, Maritime Safety Administration) gate entry into automotive, EU pressure-equipment, military, medical, and shipbuilding supply chains. The company markets itself through a multi-language corporate website (English, Chinese, Japanese, German), content marketing via technical articles, industry association membership, and active participation in international trade exhibitions including ACHEMA and the Munich environmental exhibition.
