Crankshafts are a major motorcycle engine rotating part, which after it has been connected to the connecting rod, will carry out the conversion between reciprocating and rotational motion. It is a key engine component, and is often made of carbons teel or nodular cast iron, with crankshaft rotation acting as the driving force for both the engine and overall mechanical system.

Production process
Production capability
1. We have 1600 forged engine crankshafts for customers to choose from, all of which are extremely cost effective.
2. We use a warehouse management system that follows ISO/TS16949 quality management system standards and a 6S lean management system that covers SEIRI, SEITON, SEISO, SEIKETSU, SHITSUKE, and SECURITY, thus ensuring a long product service life, as well as an easy warehouse storage and organization.
There are friction screw presses covering 630tons, 1000tons, 1600tons, and 2500tons for forgings production ranging from 1-25kg.
600-ton for forgings varying from 1-4 kg
1000-ton for forgings varying from 3-8 kg
1600-ton for forgings varying from 4-12 kg
2500-ton for forgings varying from 8-25 kg
4. We have 10 CNC processing centers, which are used for one-time processing of forgings with complex geometric shapes or with multiple processing procedures, making them more efficient and precise when compared to normal NC processing.
Raw materials mainly include carbon steel, alloy steel, stainless steel, aluminum, and copper, etc., commonly used materials are 45#, Q235, Q345, 35Mn, 65Mn, 40Cr, 35CrMo, 42CrMo, 4140, 20CrMnTi, 20CrNiMo, 304, 310, 316, 431, Al, Copper, etc.
Forging equipment has 160tons, 300 tons, 400 tons, 630 tons, 1000 tons, 1600 tons, and 2500 tons, can forge ten grams to 55 kilograms of rough forging or precision forging products.
Machining equipment has lathe, drilling machine, grinder, wire cutting, CNC and so on.
Heat treatment includes normalizing, tempering, annealing, quenching, solid solution, carburizing, etc
The surface treatment includes shot blasting, spray painting, electroplating, electrophoresis, phosphate and so on
The testing equipment includes spectrometer, metallographic analyzer, hardness meter, tensile machine, impact testing machine, fluorescent magnetic particle flaw detector, ultrasonic flaw detector, three coordinates, etc
Products are widely used in petrochemical industry, engineering machinery, auto parts, locomotive and railway parts, metallurgy, shipbuilding, military products and other fields.
Mold development process
The R&D team conducts CAD design, CAM, UG, SOLIDWORKS modeling work.
We use superfine die steels as the raw material, allowing them to be processed with a CNC center, ensuring that the die steel’s precision is ensured and has excellent fatigue resistance, abrasive resistance, making sure that the forgings are produced in high quality.
There are more than 2000 sets of molds here at our company. The customers can choose any of them for processing to minimize cost. We perform inventory taking, clearing and recording every week to ensure that the production proceeds as scheduled.
Our mold warehouse is managed by following the IATF16949 quality management system and “6S lean managementâ€, giving a long service life to the mold and making it convenient for use and storage.
