Frequently Asked Questions

Q: What makes the ductile iron frame better than standard cast iron for thread rolling?

Ductile iron provides significantly higher tensile strength and elasticity, which prevents the machine from cracking or deforming under the intense pressure required for metal forming, thus extending the equipment's lifespan.

Q: Can the machine be adjusted for different rebar diameters?

Yes, the 20-type series features variable frequency speed regulation, allowing operators to adjust the processing speed to accommodate various materials and diameters efficiently.

Q: Which electrical brands are used in the Automatic Rebar Spoke machine?

We utilize internationally recognized first-line brands, specifically Schneider and Siemens, to ensure the electrical system is reliable, safe, and easy to maintain worldwide.

Q: How is the machine protected during international shipping?

Machines are wrapped in wound plastic film to prevent corrosion and dampness, then secured in stable, fumigation-free plywood packages to ensure smooth customs clearance and protection from impact.

Q: Does Hebei Moto Machinery provide support for LCL and FCL shipping?

Yes, we cooperate with reputable logistics teams for LCL shipments and utilize skillful workers for professional FCL container loading to ensure safe delivery.

Q: Is the equipment certified for international export?

Absolutely. Our company has passed the ISO 9001 International Quality Control System certification, and our products are successfully exported to Europe, Africa, the Middle East, and Southeast Asia.
