TECHNICAL OVERVIEW
A C‑Frame Double Crank Mechanical Press is engineered for applications that require wider tooling, balanced force distribution, and consistent accuracy across the entire die surface. The dual‑crankshaft design minimizes slide tipping and improves parallelism, making it ideal for medium‑to‑large components where uniform forming pressure is essential. This configuration provides greater stability than a single crank press, especially during high‑speed blanking, multi‑hole piercing, and progressive die operations. The open‑front C‑frame structure enhances accessibility for tool changes, coil feeding, and operator visibility, while maintaining the rigidity needed for demanding production environments. Manufacturers choose this press when they need a reliable, cost‑effective machine capable of handling larger dies, maintaining tight tolerances, and delivering repeatable performance across long production runs.
A double crank mechanical press offers several advantages for manufacturers who require stability, accuracy, and efficient force distribution. The dual‑crankshaft system ensures that force is applied evenly across the slide, reducing deflection and improving part consistency—especially important for wider dies and medium‑sized components. Compared to single crank presses, the double crank design provides better slide guidance and improved parallelism, which helps extend tool life and maintain dimensional accuracy. It also supports higher tonnage capacities and larger bed sizes without compromising performance. The C‑frame layout adds accessibility and a compact footprint, making it easier to integrate into existing production lines. For operations that demand reliability, speed, and uniform forming pressure, a double crank mechanical press is a proven and efficient choice.
This C‑Frame Double Crank Mechanical Press combines a reinforced frame, dual‑crankshaft architecture, and a high‑efficiency mechanical drive system to deliver exceptional stability and precision. The double crank design ensures balanced force distribution and improved slide parallelism, making it ideal for medium‑size stamping, blanking, and forming applications. The rigid C‑frame structure minimizes deflection while providing excellent access for tool changes, coil feeding, and maintenance. Additional features may include adjustable stroke length, high‑speed operation, overload protection, and compatibility with automation equipment. The mechanical drive system offers reliable, low‑maintenance performance, making it suitable for continuous production environments. Manufacturers benefit from consistent accuracy, long tool life, and a durable press that delivers strong value across a wide range of metalworking applications.
IMPROVED SERVICE LIFE
High Fequency Quenching
We use high-frequency quenching on our C-Frame Press slide guides, achieving hardness levels over HRC 48. Rail grinding precision is maintained above Ra 0.4, with an average flatness of 0.03 mm/m². The result is reduced wear, sustained precision, and a longer service life.
GET PARTS ANYWHERE
Open Source Control System
Our C-Frame Press control systems are made with open-source, readily available components, with no custom-made OEM parts.
STRENGTH AND WEAR RESISTANCE
Bronze Worm Gear
In our C-Frame Press, bronze worm gears reduce the risk of seizure and make die adjustments smoother and more efficient. The bronze-copper alloy (ZQSN10-1) provides superior strength and durability, extending service life compared to traditional cast iron worm gears.
MORE STAMPING
Less Seizing
Our C-Frame Press uses a sintered TM-3 copper alloy ball seat instead of traditional cast iron. The TM-3 copper alloy offers a surface strength of 1,000 kgf/cm², reducing the risk of seizure and extending the service life of this critical component.
LESS WEAR AND TEAR
Copper Sleeves
The all bronze-copper alloy sleeves are made of Tin, Phosphorus Bronze ZQSN10-1 and are about 1.5 times stronger then just copper BC6. The result is reduced wear.
STRONGER AND BIGGER
Hardened Crankshaft
Our C-Frame Press crankshafts are made from high-strength 42CrMo alloy and designed larger than most for added durability. Each shaft is forged, heat-treated, and flaw-inspected, resulting in a strength 1.3 times higher than standard 45 steel and greatly reducing the risk of breakage.
HARDENED AND STRONGER
Chromium Plated Thimble
Our C-Frame Press thimbles are chromium plated with a surface finish between Ra 0.4 and Ra 0.8, then hardened to HRC 48. This ensures an exceptional oil seal and extends the overall lifespan of the sealing system.
LESS WEAR ON TOOTH SURFACES
Hardened Gear Shaft
The gear shaft is made of high strength 42CrMo alloy and all tooth surfaces are treated with intermediate frequency which increases hardness. The advantage of this is less wear on tooth surfaces and higher meshing precision.
IMPROVED SERVICE LIFE
High Frequency Quenched Gear Drive
We use high-frequency quenching on our C-Frame Press gear drives, achieving hardness levels over HRC 48. Rail grinding precision is maintained above Ra 0.4, with an average flatness of 0.03 mm/m². The result is reduced wear, sustained precision, and an extended service life.
Safety Light Curtains
WORKER SAFETY SHOULD NOT BE AN OPTION FOR A PRESS
We take operator safety seriously — that’s why all our C-Frame Presses come equipped with full-size CAT4 safety light curtains as a standard feature. These light curtains integrate seamlessly with other safety systems to provide maximum protection for the operator at all times.
MORE OIL, LESS WEAR
Bigger Oil Piping
Our C-Frame Presses use 8 mm diameter copper lubrication pipes to ensure consistent oil delivery to all critical points. The larger, higher-gauge design minimizes the risk of breakage and guarantees a steady flow of lubrication throughout the system.
OPTIMIZED STRUCTURE
Finite Element Analysis (FEA)
Through SolidWorks finite element analysis (FEA) we optimize the press structure and refine the design for maximum performance.
