Shanxi Jianing Forging adopts mature precision die forging processes, capable of producing gears, valve bodies, automotive swing arms, piston rods, and impeller die forgings. It offers high dimensional accuracy, and can be processed from carbon steel, stainless steel, and alloy steel, meeting the needs of multiple industries.
During the operation of the ship's main engine, if the bolt die forging has insufficient strength or accuracy deviation, it can at best cause equipment vibration intensification and at worst lead to safety accidents. Jianing Forging focuses on solving this challenge by adopting a full-process die forging process that helps each marine main engine bolt die forging maintain reliable connections under harsh sea conditions, reducing replacement frequency and lowering operation and maintenance costs.

The marine main engine bolt die forgings are designed by Jianing Forging according to ship standards, and are formed in one round through fine dies, eliminating the metal flow interruption issues that may occur during traditional cutting processes. The product has a dense internal structure and stable overall mechanical properties, making it suitable for bolted connection needs of various medium- and high-speed marine main engines, generator sets, and auxiliary equipment. From material selection to finished product shipment, every step is controlled by the quality management system, supporting long service life.
Integrated Forging: One-time heating forging ensures complete metal flow lines and higher strength than cut parts of the same specification.
Carefully selected materials: Made of marine-grade alloy steel or stainless steel, with customizable corrosion and high-temperature resistance solutions.
High dimensional accuracy: mold tolerance control, tight fit on the mating surface, reducing stress concentration.
Traceability: Each product is labeled with batch number and material number, supporting full traceability from raw materials to heat treatment.
This product is a non-standard custom component, with prices varying greatly depending on material, specifications, quantity, and surface treatment requirements. Jianing Forging offers free technical evaluation and quotation services. Customers can provide drawings or samples, and we will provide reasonable and transparent customized quotation plans.
Jianing Forging ensures quality assistance for products leaving the factory; if manufacturing defects cause failure, returns or repairs are provided within the agreed scope. At the same time, we offer users recommendations for optimizing forging processes, feedback on batch delivery progress, and long-term technical consultation, helping to support the entire cycle from order to use.
