Fully Integrated Workflow
Single-source CNC machining, bending and welding cuts handoffs, reduces lead time and costs.
Exceptional Precision
Achieve dimensional accuracy down to ±0.01 mm on critical features for interchangeability.
Wide Material Expertise
Deep knowledge of stainless steel alloys ensures correct bending spring-back compensation and weld metallurgy.
Rapid Prototyping to Volume
Early DFM advice, quick-turn proofs in 3–7 days, scalable to thousands of units with consistent quality.
Comprehensive QC
ISO-compliant processes, full traceability, and 100% part inspection guarantee performance and compliance.
Smart Forming & Welding
IoT-equipped press brakes and welding cells for real-time process monitoring and adaptive control.
Hybrid Manufacturing
Combining additive metal deposition with CNC bending and finishing to produce complex, lightweight frames.
Sustainable Operations
Closed-loop coolant systems, energy-efficient bending presses, and recycling of scrap stainless to reduce environmental impact.
Advanced Coatings & Treatments
Incorporating nanoceramic or DLC coatings post-fabrication for wear resistance in extreme conditions.
Architectural & Structural
Stainless brackets, handrails, facade panels and support frames requiring precise bends and weld joints.
Aerospace Assemblies
Ducting, brackets, struts and housings that demand strict tolerances and weld integrity.
Medical Equipment
Instrument housings, chassis, and support fixtures with polished finishes, biocompatible passivation.
Automotive & EV
Exhaust components, battery trays, battery pack frames, and chassis reinforcement parts.
Food & Beverage Processing
Sanitary piping bends, welded manifolds and bracketry for hygienic environments.
Q1: What is your minimum order quantity (MOQ)?
Prototypes start at 1 piece; MOQ for production runs depends on part complexity and material cost.
Q2: What lead times can I expect?
Prototype: 3–7 business days
Small batch (10–100 pcs): 10–15 business days
High volume: 3–6 weeks, depending on quantity and finishing
Q3: How do you control bend accuracy?
We use CNC press brakes with servo-driven axes and real-time angle sensors, plus sample part verification to offset spring-back.
Q4: Which welding certifications do you hold?
Our welders are certified per ISO 9606 for stainless steels; we offer full WPQR documentation on request.
Q5: How are parts packaged and shipped?
Each part is cleaned, rust-preventive coated or passivated, wrapped in protective film, and packed in foam-lined boxes or crates. We ship worldwide via air, sea or express courier.
