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 made with open-source, readily available components, with no custom-made OEM parts.
STRENGTH AND WEAR RESISTANCE
Bronze Worm Gear
Bronze worm gears reduce the probability of seizure and greatly reduce the process of die adjustment. The bronze-copper alloy (ZQSN10-1) extend the service life when compared to cast iron worm gears.
MORE STAMPING
Less Seizing
We use a sintered TM-3 copper alloy ball seat in our C-Frame Press, 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 component.
LESS WEAR AND TEAR
Copper Sleeves
The C-Frame Press uses all bronze-copper alloy sleeves made from Tin Phosphorus Bronze ZQSN10-1, which are about 1.5 times stronger than standard copper BC6. The result is reduced wear and improved durability.
STRONGER AND BIGGER
Hardened Crankshaft
Our crankshafts are made of high strength 42 CrMo alloy and are larger than most. They are forged, heat treated and inspected for flows. The result is that the strength is 1.3 times higher than that of 45 steel and breaking is reduced.
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 excellent oil seal and extends overall seal life.
LESS WEAR ON TOOTH SURFACES
Hardened Gear Shaft
In our C-Frame Presses, the gear shaft is manufactured from high-strength 42CrMo alloy, and all tooth surfaces are treated with intermediate-frequency hardening to increase surface hardness. This results in reduced wear, smoother meshing, and higher transmission precision.
IMPROVED SERVICE LIFE
High Frequency Quenched Gear Drive
We use a high frequency quenching on our gear drives which reaches over HRC 48. Rail grinding is above RA 0.4 and the average flatness is 0.03 mm/m2. The result is reduced wear, sustained precision and longer service life.
SAFETY LIGHT CURTAINS
Worker Safety Should Not Be An Option For A Press
We take worker 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 with the press’s other safety systems to ensure maximum operator protection at all times.
MORE OIL, LESS WEAR
Bigger Oil Piping
Our C-Frame Presses use 8 mm diameter copper lubrication pipes to deliver consistent oil flow to all critical points. The larger, higher-gauge design reduces the risk of breakage and ensures reliable 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.
