Product Description
STE-200 Closed Double Crank Punch Press with Integral One-Piece Frame
Product Overview
The STE-200S is a heavy-duty closed double crank punch press featuring an integrated one-piece H-frame construction. Designed for precision stamping of metal hardware and auto parts, this 200-ton capacity press delivers exceptional rigidity and stability for demanding industrial applications.
Integrated H-Frame Construction
Extra-thick steel plates welded into a one-piece closed frame with secondary stress relief annealing for maximum rigidity and minimal deflection.
Dual Crankshaft Transmission
Twin synchronous 42CrMo alloy crankshafts with wide-span double connecting rods for even load distribution and heavy forming capability.
Wet Friction Clutch System
Oil-cooled wet clutch enables continuous high-speed stamping without overheating, ideal for automated production lines.
Precision Slide Guidance
Four-corner eight-sided hardened slide guides maintain dimensional accuracy under large eccentric loads.

Precision Standard JIS Class 1
Core Features & Components
  • Integrated One-Piece Closed H Frame: Constructed with extra-thick steel plates via integrated welding and secondary high-temperature stress relief annealing. Frame rigidity reaches 1/8000 with minimal deflection under full nominal load.
  • Four-Corner Eight-Sided Hardened Slide Guide: Fully quenched and precision ground guide rails with micro-clearance matching tolerate large eccentric loads without lateral runout.
  • Dual 42CrMo Alloy Crankshaft & Wide-Span Double Connecting Rods: Twin synchronous crankshafts forged from high-strength 42CrMo alloy steel with overall carburizing and precision grinding.
  • Wet Pneumatic Friction Clutch-Brake System: Oil-cooled wet clutch features large friction contact area and low heat generation for non-stop high-speed stamping.
  • 15.6-inch Digital PLC Touch Control System: Preloaded with multiple stamping motion curves and supports one-click parameter copying for multi-line mass production.
  • Standard Large-Tonnage Air Die Cushion: 14-ton air cushion with 100mm stroke provides uniform blank holder force to suppress sheet wrinkling.
  • Complete Industrial Safety Protection: Multi-beam safety light curtain, hydraulic overload protection, emergency stop circuit, and two-hand operation mode.
  • Forced Thin Oil Circulating Lubrication: Independent circulating oil pump supplies lubricant to all moving parts with real-time monitoring.
Applications & Industries
Material Compatibility: 1-10mm cold rolled steel, galvanized steel, SUS stainless steel, aluminum alloy, and copper plate
Primary Processes:
  • Thick plate blanking & trimming
  • Medium & deep drawing
  • Multi-station progressive forming
  • Heavy bending, flanging, embossing and cold extrusion
Target Industries:
  • New energy auto components
  • Home appliance sheet metal
  • Lithium battery structural parts
  • Heavy hardware and construction hardware
  • Large electrical equipment accessories
Competitive Advantages
  • Integrated closed H-frame provides ultra-high rigidity with zero opening deflection under heavy eccentric loads
  • Symmetrical dual synchronous crankshaft structure distributes force evenly, extending component service life
  • Standard oil-cooled wet clutch supports continuous automated production without frequent cooling shutdowns
  • 14-ton high-capacity air cushion included as standard equipment
  • Four-corner eight-sided hardened slide guides accommodate large eccentric offsets for progressive dies
  • Forced circulating lubrication system reduces maintenance frequency and labor costs
  • Symmetrical balance design minimizes vibration and noise for stable unmanned operation

Professional FAQ
What are the core structural differences between STE-200S and ST series C-frame presses?
  • Frame Rigidity: STE features integrated closed H dual-column structure with rigidity of 1/8000 and nearly zero deflection. ST series open C-frame design generates obvious opening deformation under heavy eccentric loads.
  • Transmission Mechanism: STE uses dual synchronous crankshafts and wide-span double connecting rods for uniform load distribution. ST uses single crankshaft with limited thick plate capacity.
  • Clutch Configuration: STE-200S includes standard oil-cooled wet clutch for continuous production; ST series dry clutches require regular cooling.
  • Process Capability: STE supports 1-10mm thick plates and medium/deep drawing; ST is limited to sheets under 6mm for light bending and blanking.
What service advantages does the wet clutch provide?
The wet friction clutch features circulating oil cooling with large friction contact area and low surface temperature during continuous operation. It can run 24 hours on automated lines without shutdown cooling. Wear rate is reduced by over 40% compared to dry clutches, delivering longer service life and lower replacement costs.
Is the air die cushion standard equipment?
Yes, the 14-ton heavy-duty air die cushion is standard equipment with no extra charges. It provides 100mm effective cushion stroke and outputs uniform blank holder force across the entire worktable to restrain material wrinkling during drawing operations.
What safety systems are integrated?
  • Multi-beam safety light curtain with instant emergency stop
  • Full-load hydraulic automatic pressure relief overload protection
  • Dual-solenoid wet clutch anti-secondary drop interlock circuit
  • Mushroom emergency stop button and two-hand safety operation
  • Auto alarm and machine lock for overload, low oil pressure, and insufficient air pressure
All safety assemblies comply with CE and JIS mechanical safety standards.
