How a highly reliable engine is made? The answer should not be short. Scientific and advanced design, exquisite processing technology, mature application experience... These are the key factors supporting the high quality of the engine. In addition to drawing design, assembly process, application support, etc., giving the engine the strongest body and bones is also the key to ensuring the high reliability of the engine. And this is inseparable from the superb casting level and high-quality casting products.
Weichai Engine Manufacturing Process Promotion
Recently, at the opening of the 14th China International Foundry Expo, Weichai demonstrated its environmentally friendly and technologically advanced casting products. Not only did it spread the manufacturing concept of “Green Weichaiâ€, but also the “high reliability of Weichai productsâ€. "We did a deep annotation. At the expo, Weichai brought its castings from Weichai Power (Weifang) Casting & Forging Co., Ltd. and Weichai Binhai Foundry Co., Ltd. to stunning appearances.
The 14th China International Foundry Expo Weichai Booth
Weichai Power (Weifang) Casting and Forging Co., Ltd.
Weichai Power (Weifang) Casting & Forging Co., Ltd. displayed the cylinder block blanks Weichai WP9H and WP12 Lanqing produced, and the Weichai 4/7/9L connected cylinder heads, gear chambers and gearbox castings.
Spectators watched Weichai's high quality castings
Among them, WP9H blanks are made of high-grade cast iron. In order to meet the requirements of Weichai's 1.8 million kilometers/30,000 hours of high reliability and 20 MPa high explosion pressure, the body strength of the cylinder block needs to reach 250 MPa. The integrated cylinder with integrated intake pipe is used. The cover body must have a tensile strength of 300 MPa.
Weichai WP7 cylinder head blank
In addition, the Weichai WP7 cylinder head blank and Baudouin M26 body exhibited represent the production volume of Weichai's cast vermicular iron.
Weichai Binhai Foundry
At the exhibition, the casting products of Weichai Binhai Foundry were Baudouin V-type M26 cylinder block and 6170 crankshaft.
Weichai casting 6170 crankshaft
It is understood that Baudouin V-type M26 cylinder body, cast iron body, mesh structure, high strength, good cooling effect; 6170 crankshaft high grade, large size, advanced production technology to ensure the casting ductile iron crankshaft scrap rate below 1.5% .
Weichai Boduan V-type M26 engine block
