Rigid Monoblock Innovation Backed by Decades of R&D
DH CNC was established in Jinan, Shandong, in 2024 as a state-of-the-art, digital-focused manufacturing facility dedicated exclusively to next-generation monoblock cast-iron busbar processing machinery. Unlike older factories with worn welding tables, our brand-new manufacturing center operates high-speed milling and gantry grinding centers, ensuring absolute machine alignment and baseline structural rigidity.
While our fabrication facility is modern, our core technical foundation rests on **15+ years of specialized industry experience** led by our founder and Chief Application Architect, Mr. David Yang. Since 2010, Yang has engineered hydraulic cylinders, PLC nesting softwares, and high-durability punching dies for global switchgear manufacturers.
By shifting from a legacy sales agent setup to direct factory application sales, DH CNC guarantees every B2B workstation is configured directly to your plant's target specifications—preventing transport-induced calibration drift and avoiding costly third-party agency markups.

Heritage Milestones & Evolution
Our founder's path in developing heavy machinery automation and precision sheet forming excellence:
Engineering Heritage & Foundation
Founder Chief Engineer David Yang led R&D divisions developing first-generation hydraulic benders and heavy CNC turret punches in Jinan.
Direct Sourcing & Global Adaptation
Pioneered grid-matching modifications (custom winding for 220V/440V 60Hz LATAM and 480V 60Hz USA grids) for direct-to-plant B2B delivery.
State-of-the-Art Factory Founding
Established DH CNC's modern Jinan manufacturing plant. Designed specifically for assembling rigid cast iron monoblock machine frames, eliminating legacy transit alignment drift.
Calibrating Your Workstation to Your Exact Plant Specifications
Standard switchgear manufacturers face severe bottlenecks because machinery agents supply "one-size-fits-all" hardware. At DH CNC, we bypass brokers to align our engineering team directly with your switchboard factory layout:
- Custom Die & Tooling Calibration: We review your STEP/DXF drawing packets to verify clearance limits and produce specialized punching, shearing, and multi-angle bending dies optimized for copper and aluminum.
- Plant Grid Winding & Compliance: Before dispatch, all motor coils, AC contactors, and hydraulic valve systems are wound and load-tested matching your regional grid standard, whether it's 220V/440V 60Hz three-phase lines or US 480V 60Hz.
- 3D Nesting Optimization: We guide your drafting team to set up nesting offsets inside our proprietary touchscreen PLC system, cutting copper scrap waste to below 3% (delivering an average 12.5% reduction in yearly metal procurement costs).
ISO 9001 Quality Control & Transit Testing
How our Jinan facility eliminates assembly errors, pressure leaks, and transit-induced misalignment.
ISO 9001 Quality Control
Every component is logged. Finished machines undergo rigorous continuous active-load hydraulic simulations for 48 hours before packing.
Grid Frequency Calibration
Factory-level winding of heavy motors to 60Hz and isolation transformer packaging ensures perfect compatibility with regional grids.
Fumigation-Free Packaging
All shipments are packed in heavy steel-reinforced, export-grade, fumigation-free wooden crates for protection during transit.
Direct WhatsApp Diagnostics
Chief application engineers are reachable 24/7. Built-in remote diagnostic modems resolve 80%+ of issues instantly.
Rigid Pre-Shipment Inspection Protocol
Heavy Industrial Switchboard Applications
Calibrated workstations powering the switchboard assembly lines of international distribution networks.
Low & High Voltage Switchgear
Calibrating multi-station punching, shearing, and bending for copper switchboards, control cabinets, and distribution panels.
Power Distribution Transformers
Precision bending and custom die forming for high-conductivity T2 red copper busbars inside heavy transformer grids.
Marine & Industrial Control Panels
Tooling configurations engineered for space-efficient marine switchboards, solar grid inverters, and battery terminal layouts.
Mr. David Yang
"When we established the DH CNC assembly base in 2024, our mission was to build a clean, high-precision manufacturing space that traditional workshops simply could not support. By applying my 15+ years of specialized R&D experience in hydraulic flow design directly to monoblock cast iron frames, we have created workstations that remain perfectly aligned through rough sea transit and run smoothly from day one at your factory gates."
