Built on a robust C-frame structure with a double-crank drive system, it ensures stable force distribution and superior accuracy throughout the stroke. The advanced servo motor drive offers fully programmable slide motion, allowing operators to optimize speed, stroke, and dwell for each application — from high-speed blanking to deep drawing. Combining rigid construction, servo technology, and customizable performance, the MDC-SV Series C-Frame Press is ideal for manufacturers in the automotive, appliance, aerospace, and general metalworking industries seeking reliability, efficiency, and consistent part quality.
TECHNICAL OVERVIEW
A C‑frame double crank servo mechanical press provides superior stability and balanced force distribution, making it ideal for applications that require larger tooling, wider bed areas, or higher precision across the entire die surface. The dual‑crankshaft design minimizes slide tipping and improves parallelism, ensuring consistent accuracy even during high‑tonnage forming or multi‑stage stamping operations. With servo control, operators can program custom stroke profiles, forming speeds, dwell positions, and approach distances to optimize performance for each job. This combination of structural rigidity and programmable motion makes the double crank configuration perfect for producing larger components, maintaining tight tolerances, and supporting progressive dies that demand uniform force across the entire working area. We have prepared a comprehensive guide to c-frame presses that can explain the structure of this type of press in comparison to other presses.
A double crank press offers enhanced stability, improved slide guidance, and better load distribution compared to a single crank design. This makes it the preferred choice for applications involving wider dies, larger parts, or operations where maintaining slide parallelism is critical. The dual‑crankshaft system reduces deflection and ensures even force delivery across the full bed, which helps extend tool life and improve part consistency. When paired with servo technology, the double crank design becomes even more capable, allowing operators to fine‑tune motion profiles for blanking, forming, piercing, and progressive stamping. Manufacturers choose double crank presses when they need higher accuracy, greater structural support, and the ability to handle more demanding or larger‑format tooling.
This C‑frame double crank servo mechanical press combines advanced servo motion control with a reinforced frame and dual‑crankshaft architecture to deliver exceptional precision and reliability. The programmable servo system allows operators to adjust forming velocity, dwell time, slide position, and stroke profiles to match the needs of each application. The double crank design provides superior slide stability, reduced deflection, and improved force distribution, making it ideal for larger dies and high‑accuracy stamping. Additional benefits include lower energy consumption, quieter operation, reduced heat generation, and extended tool life. This press is engineered for manufacturers who require consistent performance, high repeatability, and the flexibility to handle both high‑speed production and complex forming tasks.

SERVO DRIVE SYSTEM
Greater Accuracy And Efficiency
Our C-Frame Servo Press system provides superior accuracy in the moving platen’s stopping position while delivering significant energy savings during every operation.
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 an extended service life.
GET PARTS ANYWHERE
Open Source Control System
Our C-Frame Press control systems are built using open-source, readily available components. We never use custom-made OEM parts, ensuring easy maintenance and long-term reliability.
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
We use a sintered TM-3 copper alloy ball seat as opposed to cast iron. The TM-3 copper alloy has a surface strength of 1000 kgf/C m2. This alloy reduces the probability of seizure and at the same time extends the service life of this part.
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 Presses crankshafts are made from high-strength 42CrMo alloy and designed larger than most for enhanced durability. Each crankshaft is forged, heat-treated, and flaw-inspected, achieving a strength 1.3 times higher than standard 45 steel and significantly reducing the risk of breakage.
HARDENED AND STRONGER
Chromium Plated Thimble
Our thimbles are chromium plated with a surface between RA 0.4 and RA 0.8. They are then hardened to HRC 48. This provides an excellent oil seal to ensure seal life.
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 Servo 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 a longer service life.
SAFETY LIGHT CURTAINS
Worker Safety Should Not Be An Option For A Press
We are very serious about worker safety. That is why all our presses include full size CAT4 safety light curtains as a standard feature. The light curtains work along with the other safety features to ensure worker safety at all times.
MORE OIL, LESS WEAR
Bigger Oil Piping
We use 8 mm diameter copper lubrication pipes to ensure proper lubrication on all critical points. The larger and higher gauge pipes reduce the possibility of breaking and ensure a constant flow of oil.
OPTIMIZED STRUCTURE
Finite Element Analysis (FEA)
Through SolidWorks finite element analysis (FEA) we optimize the press structure and refine the design for maximum performance.
