Automobile connecting rods are the center connection rod in an internal combustion rod, and connect the piston to a crankshaft, in order to form a mechanism that moves energy from the piston to the crankshaft, then to the transmission. After the rod forging is complete, we choose different materials and production methods to ensure the quality. Most often, the connecting rod is made of a carbon steel, with investment casting, drop forging and powder metallurgy all good production process choices.
Forged steel connecting rods are available for a variety of diesel engines, ensuring the connecting rod is efficient.

Products are widely used in petrochemical industry, engineering machinery, auto parts, locomotive and railway parts, metallurgy, shipbuilding, military products and other fields.
Mold development processThe 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 management”, giving a long service life to the mold and making it convenient for use and storage.
