China National Heavy Duty Truck (Hong Kong) Co., Ltd. Jinan Casting and Forging Center China National Heavy Duty Truck (Hong Kong) Co., Ltd. Jinan Casting and Forging Center (hereinafter referred to as "casting and forging center") is China National Heavy Duty Truck Group's casting and forging production base. The center covers an area of ​​640,000 square meters and has a fixed asset of 1.5 billion yuan, consisting of 11 It consists of a management department room and seven production units, and currently employs more than 1,600 people. After more than 50 years of ups and downs, today's casting and forging centers are well-equipped with key products at the leading level in the domestic industry, and some have reached the international advanced level.
Trouble-seeking progress
Starting from the steel casting workshop of Jinan Automobile Manufacturing Plant in 1960, after more than 50 years of hard work and trials and hardships, after several mergers and upgrades, today's casting and forging centers have achieved great success in both production facilities and production processes. The proud performance reached the height of peer admiration.
On the way to the rise, the casting equipment has evolved from the original manual modeling to today's static pressure molding line, and hand-made cores have evolved into automatic core making core production;
During the development journey, the forging equipment has also developed from the backward 16T steam die forging line into today's KP12500 hot die forging production line. The forging worker's hand forging pliers has become a robot to grab red hot forgings;

Casting vermicular cast iron domestic best
In the foundry shop, the metal liquid just melted and sputtered sparked and opened the life journey of the MAN engine block and cylinder head.
Casting MAN engine block, cylinder head
You must not underestimate it here, because the mysterious vermillion is done here again.
We all know that ductile iron has high strength, but its thermal conductivity is not as good as gray iron. Gray iron has good thermal conductivity, but its strength is less than that of ductile iron. Vermicular graphite iron technology solves this problem very well. It has both ductile iron and ductile iron. The high strength, but also has a good thermal conductivity of gray iron, becoming the goal of auto manufacturers competing to chase, for European and American auto giants have been widely used in low-emission diesel engine production.
In 2012, after arduous efforts and research, the cylinder body and cylinder head of the vermicular cast iron process engine produced by the Casting and Forging Center were released through Mann's products, becoming the first domestic manufacturer to produce engine castings using European standards to achieve mass production. With the development of the year, the production volume of the vermicular graphite cast iron engine produced by the cast and forged center in 2017 is expected to reach 22,000 tons, which is far ahead in China.
The second casting part is the production department with casting axle housing as the leading product. The casting axle housings used by the leading heavy duty trucks and cement mixers are all from here, advanced equipment, strict attitude, superb craftsmanship, meticulous The pursuit of work has kept the scrap rate here below 1%.
At the same time, in order to guard the blue sky of Jinan, Quanzhou, in the production process, the production process that may cause pollution is undergoing the upgrading of production processes. The industry's original cold-cold alcohol-based paint drying process greatly reduces smoke generation. The entire plant area, regardless of the casting smelting process or forging bar heating process and heat treatment process, all use electric heating, completely avoid the soot emissions from coal combustion.
Forging equipment advanced technology leader
Entering the first-class forging company, the world-class SMS Mark KP125MN and MP80MN hot die forging presses are the first to enter the eyes, wedge cross-rolling production lines, 16-ton electro-hydraulic hammer production lines, 6,300-ton hot die forging press production lines, and 3,150 tons Hot die forging press production line, 1600 ton flat forging machine production line, 630 ton flat forging machine production line; large, medium and small parts quenched and tempered production lines, isothermal annealing lines, large and medium-sized heat treatment suspension lines and other heat treatment production lines are scattered The various positions of the workshop.
China National Heavy Duty Truck Automation Production Line
These equipments are all precious metals, represent the highest level of domestic forging process, the price is astonishing, a high degree of automation, intelligence, less staffing, make the casting and forging center forging workshop become the highest per capita assets of Sinotruk The unit!
Endless pursuit of quality pieces
Good equipment, good craftsmanship, highly educated talents, and output from the casting and forging centers must also be good products, but the endless pursuit of quality in the cast and forge center has never been a moment's relaxation.
Here, there is a complete quality system established in accordance with the ISO/TS16949 standard and customer requirements. There are a variety of internationally advanced processes and product testing facilities, such as a camera-type 3D scanner and 5 direct-reading spectrometers. HW2000 infrared carbon and sulfur analyzer 5 sets, universal material testing machine 4 sets, Hexagon 12210 coordinate measuring machine 1 set, JB-300C impact tester 1 set, Germany OCC image analyzer 1 set, automatic Brinell hardness tester One Taiwan and so on. Key features have online detection capabilities.
Strict quality control concept, high-end quality testing equipment, to ensure that each piece of casting and forging center product quality.
Strong technical and technological research and development
Casting and forging center has a strong technical development and application capabilities, has a highly educated, high-quality R & D team and many experienced high-skilled personnel.
Equipped with advanced computer aided design LAN, using AutoCAD, PROE, UG, CATIA, CASTSoft casting solidification simulation, APIS-FMEA and other software for new product development and design, tooling design, mold design and FMEA preparation. At the same time, it has established extensive technical cooperation with dozens of supporting manufacturers, research institutes and universities.
50 years of forging ahead, 50 years of trials and hardships, the casting and forging center as a witness to Jinan's industrial development in Quancheng has achieved a modern industrial road from manual casting and forging to automation and intelligence; The forging center is entering a new era with a bold attitude and dedicated to the society with more sophisticated products. As long as you open a vehicle manufactured by China National Heavy Duty Truck, you are assured and happy. The heavy-duty casting and forging center of China National Heavy Duty Truck Co., Ltd. will definitely offer you high-quality, high-performance products to escort you and make your vehicle more durable and easy to use!
