120 ton press machine

When sourcing a 120-ton press, you must prioritize the Nominal Pressure Stroke, which defines the point where the machine reaches its full capacity. Ensure the Bolster Area (Table Size) and Slide Dimensions accommodate your specific dies. Additionally, verify the Stroke Length and Strokes Per Minute (SPM) to ensure the machine meets your production speed requirements. For high-precision work, look for JIS Class 1 accuracy standards and a high-rigidity steel frame to minimize deflection.

Safety is paramount in metal forming. The machine must be equipped with Dual-Hand Control Buttons and Light Curtains (Photoelectric Safety Devices) to prevent accidental injury. For international trade, ensure the supplier provides CE Certification (for Europe) or adheres to OSHA/ANSI B11.1 standards (for the US). A Hydraulic Overload Protector (HOLP) is a critical feature that prevents damage to the machine and dies during operation.

The choice depends on your usage scenario. A Mechanical Press is ideal for high-volume, high-speed stamping and blanking due to its fixed stroke and rapid cycle times. Conversely, a Hydraulic Press is better suited for deep drawing or forming where full tonnage is required throughout the entire stroke. For 120-ton requirements, mechanical presses are more common in automotive and electronics parts manufacturing.

Prioritize machines with an Automatic Lubrication System (either oil or grease) to reduce wear on the crankshaft and gears. Check for the availability of PLC Control Systems (such as Mitsubishi or Siemens) which simplify troubleshooting. Ensure the Clutch and Brake system is a high-performance pneumatic type to ensure rapid stopping and heat dissipation during continuous operation.

Look for the 'Audited Supplier' badge, which indicates the factory has been verified by third-party agencies like SGS or Bureau Veritas. Review the supplier's Business License and Export Experience specifically for heavy equipment. It is highly recommended to request a Video Factory Audit or hire a third-party inspector to perform a Pre-Shipment Inspection (PSI) to verify the machine's tonnage and accuracy before it leaves the factory.

Due to the weight (often exceeding 10-15 tons), these machines require Heavy-Duty Sea Freight and specialized containers (like Flat Rack or Open Top containers). Ensure the supplier uses Vacuum Packaging and Anti-Rust Coating to prevent corrosion during sea transit. You must also negotiate On-site Installation and Commissioning services; many top-tier suppliers provide engineers for overseas setup, though you may need to cover travel expenses.

Utilize Secured Payment services provided by Made-in-China.com to ensure funds are only released upon proof of shipment. For large-scale machinery, a common payment structure is 30% T/T as a deposit and 70% L/C (Letter of Credit) or T/T after inspection but before shipment. Avoid transferring funds to personal accounts; always use the Company's Official Bank Account as listed on the platform.

Heavy machinery requires a robust after-sales plan. Negotiate a minimum 12-24 month warranty on core components like the crankshaft and motor. Demand a 'Wear-and-Tear Parts Kit' (seals, fuses, switches) to be included with the initial shipment. Confirm that the supplier can provide Remote Technical Support via video call to assist your local maintenance team in case of downtime.
