Built for Heavy-Duty Industrial Applications
Ningshing Precision Machinery specializes in open die forgings for medium to large components, delivering integrated solutions from raw material to finished parts.
With strong material know-how and supply chain capability, we combine steel sourcing, open die forging and precision machining. Open die steel forgings are produced with strict control over forging temperature, deformation ratio, heat treatment, and machining precision.
We support customers with customized forging solutions according to specific technical requirements, including dimensions, shapes, materials, hardness, mechanical properties.
Open die forging is a metal forming process in which heated steel is shaped between multiple dies that do not completely enclose the material.
Unlike closed die forging, the workpiece is free to move during deformation, allowing manufacturers to create large, customized, and high-strength components with excellent internal structure.
This process is widely used for industrial parts that require superior mechanical performance, reliability, and long service life.
NSPM manufactures a wide range of open die forging parts for industrial machinery, tooling systems, and heavy-duty applications.
Our forging solutions are available in different sizes, geometries, and material grades to meet various operational requirements.
Forged shafts and stepped shafts are widely used in gear shafts, transmission systems, and heavy machinery components requiring high strength and durability.
NSPM manufactures forged rings for bearings, flanges, wind power rings, and pressure vessels with excellent structural integrity and fatigue resistance.
Our forged discs and pancake forgings are ideal for mold bases, steel plates, and structural components requiring stable mechanical performance.
Forged cylinders and sleeves are commonly applied in hydraulic cylinders, bushings, and mechanical housings operating under heavy loads and pressure.
NSPM supplies forged rolls and rollers for metallurgical equipment, rolling mills, and industrial processing systems requiring superior wear resistance.
Our hollow forgings are suitable for lightweight structural parts and pressure components that require reduced weight with reliable mechanical strength.
NSPM also provides customized special-shaped forgings manufactured according to customer drawings for unique machinery and industrial equipment applications.

NSPM supplies open die steel forgings for a wide variety of industrial applications and engineering projects. From small forged components to ultra-heavy industrial forgings weighing tens of tons, NSPM provides dependable manufacturing capability and flexible production solutions for global industrial customers. We also support customers with customized processing services including rough machining, finish machining, ultrasonic testing, mechanical testing, and heat treatment.
Open die forging delivers high structural strength and excellent internal quality for heavy industrial components. It allows flexible production of large, customized parts with reliable performance. NSPM ensures stable quality through controlled forging and heat treatment processes.
One of the biggest advantages of open die forging is the improvement in mechanical properties. During forging, the steel grain structure becomes more refined and aligned with the shape of the component. This significantly enhances strength, toughness, impact resistance, and fatigue life.
Compared to cast or fabricated parts, open die forged components have fewer internal defects and better structural integrity. This makes them highly suitable for heavy-load and high-stress applications.
Open die forging offers excellent flexibility for customized production. Unlike closed die forging, it does not require expensive dedicated dies for every component shape. This allows to efficiently manufacture customized forgings in different sizes and geometries with lower tooling costs.
The process is especially suitable for small and medium production batches, oversized parts, and specialized industrial components. Customers benefit from shorter lead times, reduced development costs, and greater design flexibility.
Large industrial components often exceed the practical limits of casting or closed die forging. Open die forging is ideal for producing extra-large shafts, rings, cylinders, and heavy machinery parts weighing several tons.
NSPM has the capability to manufacture heavy forged components for mining equipment, marine systems, power generation facilities, and industrial presses. These forgings maintain excellent internal quality even at large dimensions.
NSPM helps customers select the most appropriate forging solution according to product dimensions, mechanical requirements, production volume, and cost considerations.
NSPM open die forgings are widely used in mining, energy, aerospace, and oil & gas industries.
These sectors require components that can withstand high loads, pressure, and harsh environments.
Our solutions support critical equipment with long service life and reliability.
Mining and heavy machinery industries require components capable of withstanding extreme loads, abrasion, and continuous operation. NSPM supplies forged shafts, rollers, cylinders, gears, and structural parts for crushers, excavators, mills, presses, and other heavy equipment.
Aerospace and defense applications demand materials with high strength, fatigue resistance, and precise structural performance. NSPM provides forged rings, discs, shafts, and special-shaped forgings for aerospace systems, military equipment, and high-performance engineering applications.
Power generation and oil & gas industries operate under high pressure, elevated temperature, and severe mechanical stress. NSPM manufactures forged components for turbines, generators, drilling systems, pressure vessels, valves, and energy infrastructure equipment.
NSPM applies advanced forging techniques to shape steel with improved grain structure and mechanical properties.
Processes such as drawing, cogging, edging, and upsetting ensure precise material control.
Each method is optimized to meet different industrial forging requirements.
01
Drawing out increases forging length while reducing section thickness. NSPM uses this process to produce shafts, bars, and elongated components with improved grain structure and mechanical strength.
02
Edging redistributes material into targeted areas before final shaping. NSPM applies edging techniques to improve dimensional accuracy, forging efficiency, and material utilization during production.
03
Cogging reduces large steel ingots into smaller sections through repeated deformation. NSPM uses advanced cogging processes to improve internal quality and prepare forgings for machining.
04
Upsetting increases the cross-sectional area by compressing forging length. NSPM uses this technique for discs, flanges, and thick components requiring excellent structural integrity and strength.
NSPM provides integrated open die forging, heat treatment, and CNC machining capabilities, producing industrial components from small to ultra-heavy sizes with precise quality control and reliable delivery performance.
