V. What casting processes are used to produce the crankshafts?

The company is equipped with 3 automatic iron mold coated sand molding lines. It uses advanced processes and testing methods such as induction furnaces of well - known domestic brands for melting, automatic iron mold coated sand molding, in - furnace spheroidization, fixed - point pouring, stream inoculation, core shooting machine for core making, and German spectrometer for in - furnace chemical composition analysis. From the procurement of raw materials to all links of the production process, strict control is implemented. The casting material quality stably reaches QT800 - 6 and QT900 - 5, and the company has the ability to produce ductile iron and gray iron castings with various material requirements.

VI. What is the weight of your crankshafts?

In 2023, the company added a new medium and large - sized casting production line, which can achieve the production and casting of castings with a single - piece weight within 1000 Kg, further expanding the coverage of casting specifications.

VII. How to ensure the production of high - quality crankshafts?

1. Normalizing Line:

   The normalizing treatment relies on a computer - controlled suspended and through - type gas normalizing heat treatment production line, which uses natural gas as the energy source. It realizes the automatic control of the entire heat treatment process of the workpiece, including heating, heat preservation, and cooling. It is at the leading level in the industry and provides a reliable guarantee for the quality of the casting material.

   

2. Quenching and Nitriding Processes:

   Induction quenching and glow ion nitriding and other heat treatment processes are used to carry out composite strengthening of the products, greatly improving the fatigue strength and reliability of the company's products, which are highly reputed in the market.

   
   

3. Machining Process:

   In the machining process, the crankshaft production line widely adopts numerical control processing technology. It is equipped with advanced equipment such as numerically controlled special lathes for crankshaft main journals and connecting rod journals, numerically controlled crankshaft fillet rolling machines, numerically controlled crankshaft oil hole drilling centers, numerically controlled crankshaft flange processing centers, numerically controlled crankshaft CBN grinding machines, and numerically controlled abrasive belt polishing machines, effectively ensuring the dimensional accuracy and geometric accuracy of the products.

   
   

4. Cleaning and Packaging Process:

   The company has built three ultrasonic cleaning production lines, which integrate ultrasonic cleaning, high - pressure internal surface spraying, drying, and cooling functions. The product cleanliness reaches the high cleanliness requirement of being free from cleaning before installation, and the cleanliness index leads the same industry.
