Forging Excellence, Driving the Future - A Comprehensive Showcase of Forging Products from Jiangsu Changli Equipment Manufacturing Co., Ltd.

In the vast world of metal processing, forging technology is like magic that turns ordinary metal billets into the core framework supporting modern industry. Jiangsu Changli Equipment Manufacturing Co., Ltd., located in the manufacturing hub of Jiangyin, Jiangsu, is an outstanding practitioner of this ancient yet innovative craft. With its full-range forging capability from 100kg to 20,000kg, the company has become a core supplier for domestic large locomotives, coal mining machinery, petroleum machinery, shipbuilding and other industries. Its products are also exported to Europe, Southeast Asia and other regions, building a solid foundation for industrial power with exquisite craftsmanship.

Technological Strength: The Core Foundation of Excellent Quality

Changli Equipment deeply understands the essence of forging technology, perfectly integrating traditional craftsmanship with modern technology to build an advanced production system covering the entire process of Free Forging, Hot Forging and other processes. The company is equipped with more than 30 precision equipment such as 2000-ton hydraulic press, ring rolling machine and 3-ton forging hammer, providing strong hardware support for the forming of various forgings. Among them, free forging technology excels in producing large and special-shaped forgings, reshaping metal through precise strikes of forging hammers under controlled external forces; while hot forging technology achieves better mechanical properties and metallographic structure by precisely controlling temperature and deformation.

In terms of quality control, Changli Equipment has established a full life cycle management system from raw materials to finished products. Three core testing links - chemical composition testing, mechanical performance testing and ultrasonic flaw detection - act as three solid lines of defense to ensure each product meets strict quality standards. The company adopts advanced production processes of "high-power electric furnace external refining (LF) + vacuum degassing (VD) + fast forging + annealing (or normalizing) + turning", ensuring the uniformity of chemical composition and stability of mechanical properties of forgings from the source, truly fulfilling the commitment of "quality assurance".

Product Matrix: Comprehensive Forging Solutions Covering Industrial Fields

Changli Equipment's product range is rich and diverse, able to meet the personalized needs of different industries, mainly including the following major series:

Power Transmission Core Components: The company specializes in producing Crankshaft Forgings, using high-precision die forging technology and advanced nitrocarburizing technology to ensure excellent fatigue strength and wear resistance, widely used in various engine assemblies. Through computer-controlled nitrogen-based atmosphere nitrocarburizing production line, the surface hardness and core toughness of crankshafts achieve perfect balance, providing reliable guarantee for power systems.

Automotive Key Forgings: In the automotive manufacturing field, Changli Equipment's Auto Parts Forgings cover key parts such as engines, transmission systems, suspension and steering systems. These forgings, with metal flow structure formed by forging process, have higher strength and impact resistance than cast or machined parts, becoming core elements to improve automobile safety performance.

Hydraulic and Structural Forgings: As one of the company's advantageous products, Hydraulic Cylinders adopt high-strength alloy steel and precision forging technology to ensure sealing performance and durability under high-pressure working conditions. Ring Forgings and Flange Forgings, with precise dimension control and uniform mechanical properties, are ideal choices for pipeline connection and structural support.

Special Custom Products: To meet complex working condition requirements, Changli Equipment excels in producing Special-shaped Forgings, Barrel Forgings, Cylinder Forgings and other special products. The company can provide one-stop Custom Metal Forging services from material selection, process design to finished product delivery according to customer drawings, meeting technical requirements of various special working conditions.

Basic and General Parts: Sleeves Forgings, Disc Forgings and Forging Wheels adopt a combination of standardized production and personalized adjustment, ensuring mass production efficiency while flexibly meeting specific requirements of different customers.

Material Advantages: Resource Control of Special Steel

Changli Equipment has significant resource advantages in special steel forgings, establishing strong special steel supply channels, able to provide various materials such as alloy structural steel, carbon structural steel, stainless steel, spring steel, bearing steel and roll steel. The company's sufficient inventory of high-quality steel, combined with advanced material pretreatment technology, ensures each batch of forgings has a stable performance foundation. Especially in forging treatment of high-strength alloy steels such as 30CrNiMo8, the company has accumulated rich experience, able to meet strict requirements such as -40℃ low-temperature impact, with products exported in batches and recognized by international customers.

Application Fields: Empowering High-quality Development of Multiple Industries

With excellent product quality and wide applicability, Changli Equipment's forging products have been deeply integrated into multiple key industrial fields. In the locomotive manufacturing field, large shaft forgings and structural parts provide reliable guarantee for safe operation of rail transit; in the petroleum machinery field, high-pressure and corrosion-resistant special forgings facilitate efficient energy development; in the shipbuilding industry, large flanges and cylinder forgings become core components of ship power and structural systems.

Looking to the future, Changli Equipment will continue to uphold the concept of "survive by quality, develop by innovation", continuously improve forging technology level and expand product application fields. Whether for upgrading of traditional industries or development needs of emerging fields such as new energy and high-end equipment, Changli Equipment will inject continuous "forging power" into the high-quality development of China's equipment manufacturing industry with exquisite forging skills and comprehensive solutions.
