Heating & Transfer
Induction Heating Efficiency: Direct electric induction reduces energy consumption compared with gas furnaces while eliminating combustion emissions.
Servo Manipulator: Heat-resistant alloy arms with active water cooling operate above 1,000°C, using 3.0/4.5 kW drives with zero mechanical backlash.
Precision Billet Transfer: Synchronized servo indexing positions billets in die cavities within ±0.05 mm tolerance, preventing die flashing.
MES Network Integration: An onboard PLC with EtherNet/IP and Modbus TCP protocols transmits output counts, cycle speeds, and power consumption directly to factory MES systems.
Quality Control
Thermal Monitoring: Infrared pyrometers track billet temperatures between 1050°C and 1150°C, automatically rejecting blanks outside the specified range.
Dimensional Inspection: Technicians systematically sample formed nuts to verify across-flats, hole diameter, and concentricity against approved engineering drawings.
Servo Precision Checks: Multi-station transfer mechanisms are verified for positioning accuracy and repeatability during continuous production runs.
Pre-Shipment Run-In: Every machine completes a 72-hour full-load test run, with operating logs and diagnostic data archived.
Installation & After-Sales Support
On-Site Field Commissioning: Certified field engineers handle physical setup, servo parameter tuning, thermal calibration, and operator training at your facility.
24/7 Diagnostics & Parts: Onboard network modules enable immediate remote PLC troubleshooting, backed by 48-hour global dispatch for critical replacement parts.
12-Month Component Warranty: Full warranty covers core mechanical, hydraulic, and electrical parts, supported by engineers for custom tooling integration.
Packaging & Delivery
Export VCI Packaging: Vacuum-sealed rust-inhibiting (VCI) foil wrapping inside ISPM- 15-compliant, heat-treated, sea-worthy wooden crates.
Incoterms Flexibility: Standard trade options include FOB Xiamen, CIF, CFR, or DDP directly to your plant gate.
Payment Terms: Standard terms are T/T (30% deposit, 70% before shipment) or 100% Irrevocable Letter of Credit (L/C) at sight.
Container Shipping Specs: Modular sub-assemblies (2,000–3,700 kg each) fit standard high-cube containers for simplified factory rigging.
FAQ
Q: Is the 21,600 blanks per 8-hour shift figure a theoretical maximum?
A: This figure is based on continuous field-measured output at 45 strokes/min for M12 blanks under normal production conditions, not a theoretical peak.
Q: Can the modular sub-assembly weights (2,000-3,700kg) fit inside a standard 40-foot high-cube container without special permits?
A: Yes, all sub-assemblies are designed to fit within standard 40ft high-cube container weight and dimension limits, avoiding the need for flat-rack or break-bulk shipping permits in most destination countries.
Q: How is the servo manipulator's "zero backlash" specification actually verified during testing?
A: During FAT, a laser interferometer confirms zero backlash by measuring positional deviation under reversing loads at less than 0.005 mm.
Q: From which regional hub are the 48-hour emergency spare parts dispatched for buyers in Europe or the Middle East?
A: Critical spare parts for European and Middle Eastern buyers ship from our regional stock hub in Shanghai, with typical door-to-door delivery in 48-72 hours via DHL or FedEx priority service.
Q: Should I choose T/T payment or Letter of Credit for a first-time order with your company?
A: We recommend L/C at sight for first-time buyers without an existing trading relationship, since it provides bank-guaranteed payment security for both parties before goods are released.
