Frequently Asked Questions (FAQ)
What are the maximum bending capacities of your CNC press brakes?
Our 170-Ton CNC Press Brake handles up to 3.2 meters in length and processes carbon steel up to 20mm, stainless steel up to 12mm, and aluminum up to 15mm. Our 70-Ton Precision Press Brake handles up to 2.5 meters in length and is optimized for thinner gauges, processing carbon steel up to 10mm, stainless steel up to 8mm, and aluminum up to 6mm.
What tolerances can you guarantee for custom sheet metal bending?
We achieve a precision of ±0.15mm with our 170-Ton machine, which is ideal for structural brackets and heavy machinery components. For high-precision requirements, such as aerospace and medical device housings, our 70-Ton machine delivers a tolerance of ±0.1mm.
How do you prevent surface scratches and marks on aesthetic parts?
We utilize over 100 traceless bending molds and specialized tooling designed to eliminate surface marks. This process is ideal for maintaining mirror finishes on hygienic-grade stainless steel for medical, food processing, and architectural applications.
Do you offer prototyping services, and what are the typical lead times?
Yes, we provide rapid prototyping with zero mold costs for standard bends. We can deliver sample prototypes within 3 to 5 days, helping you speed up your Design for Manufacturing (DFM) verification process.
