An ISO Certified Foundry Built New In 2022
Chongqing Boyue Machinery Manufacturing Co., Ltd. — specialising in wear-resistant castings in austenitic manganese steels, high chromium white cast irons and alloy steels, on a 26,680 m² site in Qijiang District, Chongqing.
From Pangbo Metal Products To The Qijiang Works
Our president, Mr. Han, purchased the company in 2009. The old foundry, Chongqing Pangbo Metal Products Co., Ltd., was located at Mingyuetuo in Guangyang Town, Nan'an District, Chongqing.
As the business developed we began investing in a new foundry in 2020. After two years of effort we moved to the newly built works at the end of 2022, under the name Chongqing Boyue Machinery Manufacturing Co., Ltd. On-site visits are warmly welcomed.

Six Capacities That Define What We Can Pour
Melting, heat treatment, machining and testing sit inside one works, which is why an out-of-specification analysis is corrected in the ladle rather than found in a finished casting.

Eight Controlled Steps From Drawing To Steel Pallet
Pattern Making
Once drawings are confirmed, pattern making starts immediately in our own pattern shop. Thousands of finished patterns are already on the shelf, so repeat parts skip this step entirely.
Sandbox Making
Casting Process Simulation System (CPSS) is run before the moulds are made. The cavity is kept as solid and as clean as possible so that inclusions have nowhere to start.
Melting And Pouring
Charge materials are bought to a high standard and temperature is controlled through the whole pour to achieve a fine grain structure. Samples are taken to verify the analysis and adjusted if needed, then kept for at least three years for traceability.
Sandbox Opening
Also called casting cleaning. After initial cooling the box is opened, risers and runners are removed and the casting is cleaned. Cooling time is set by casting size, not by the clock.
Heat Treatment
Heating temperature is strictly controlled and castings are spaced in the furnace so they heat uniformly and meet the water fully. Quenching begins within 30 seconds of withdrawal from the oven.
Machining
After rectifying and polishing, castings are machined strictly to drawing for correct fitment. QC then carries out dimensional inspection and issues the dimensional inspection report.
Inspection
Our own physical and chemical laboratory covers spectrometry, hardness, microstructure, dye penetrant and dimensional inspection on site rather than at a third party.
Packing And Delivery
Finished parts are packed on steel pallets for forklift handling, to international standards for road, rail, sea and air transport.
The Procedures We Carry Out
High standards of raw material sourcing keep the quality right from the beginning. Every manufacturing process — drawing checking, pattern making, casting, heat treatment, machining — is strictly controlled, and the foundry is staffed by a group of well-trained people with long established expertise in casting.

Where Our Castings Go
Export
Currently 60% of our products are exported, directly by us or through other companies here in China. Castings by us have proven to outperform many other products on markets worldwide.
Domestic OEM
We provide OEM services to Chengdu Dahongli Machinery Co., Ltd. and Luoyang Dahua Heavy Industry, and supply castings to Yunnan Copper Co., Ltd. and iron ore enterprises in Shandong province.
Power Industry
With the new foundry running we have become a manufacturing base for the Chinese electric power industry, supplying wear parts such as grinding rollers and liners.
Staffing Levels
98% of our well-trained staff have been in the industry and with us for over three years; some key personnel have more than ten years' experience. Our chief engineer came from the Guangzhou Research Institute of Nonferrous Metals with over thirty years in wear-resistant castings.
External Technical Support
We work closely with related faculties at Chongqing University, Southwest University and North China Electric Power University, and hold a strategic partnership with Vesuvius plc.
Transportation
Chongqing Jiangbei International Airport for air freight, the Chongqing–Xinjiang–Europe railway through to Duisburg, and about three days inland to Shanghai Port for sea freight. Door-to-door delivery is available.
