Company overview
Three decades, one focus — industrial automation done deep enough to be trusted.
Shanghai Huaxin Minfu is built on control engineering, uniting electrical design, drive systems, and system integration into complete, process-oriented solutions. Thirty years of practice have given us a multidisciplinary team across engineering, R&D, and quality — and turned "stable production" from a promise into a result our customers see repeated on the plant floor every day. Our work spans papermaking, winding, mining, industrial control, and high-end equipment — from sectional drives for wide, high-speed paper machines, to constant-tension winder control, to plant-level MCS and common-DC-bus drive architectures. Huaxin Minfu delivers the full path for demanding sites: concept, system design, on-site commissioning, and lifetime service. Real engineering strength, we believe, lives not in the proposal but in a line that simply keeps running.

Delivering automation, drive control and integration across papermaking, mining, industrial control and OEM manufacturing.
Integrated engineering capability
From control architecture to on-site commissioning, from electrical design to long-term service — we don’t supply parts, we take systems end to end, so complex engineering closes the loop within a single team. Across papermaking, winding, drive, and plant-wide control, we cover the full path from concept to lifetime service.
Electrical drive control
AC/DC drive applications, multi-motor coordination, sectional control, speed synchronization, drive cabinets, and process-oriented motor control.
PLC and MCS control systems
Programmable control systems, distributed I/O, operator interfaces, data communication, system configuration, and workshop-level control.
High-speed paper-machine drives
Sectional drive and speed-chain control for wide, high-speed paper machines — automatic master/slave load sharing in the wire section, tension and draw coordination, adapted to graphic, packaging, and corrugating grades.
Winder drive control
Electrical drives for double-drum winders: constant tension, bottom-roll torque difference, rider-roll pressure regulation, length/diameter counting, and deceleration stop, matched to high-speed top-feed winding.
Intelligent power distribution
Power distribution engineering, detection devices, actuators, drive systems, electrical equipment selection, and field device integration.
Engineering design and delivery
Application systems designed around customer processes, site conditions, production goals, documentation, installation, and acceptance needs.
Commissioning and lifecycle service
On-site commissioning, technical training, maintenance support, troubleshooting, and long-term service for stable production.
Industrial focus
For three decades our engineering has been proven on real production lines — across papermaking, mining, industrial control, and high-end intelligent OEM manufacturing. Different industries, the same reliability.
Papermaking
Sectional drive, constant-tension control, and common-DC-bus drive architecture for high-speed paper machines and winders — across graphic, packaging, and corrugating grades.
Mining
Rugged control and power-distribution systems built to run reliably in harsh, dust-heavy environments.
Industrial control
PLC/MCS integration, supervisory systems, and plant-wide control for continuous manufacturing.
High-end intelligent OEM
Custom automation and drive solutions engineered into advanced equipment and machinery.
How we deliver
How we deliver
Every project begins with understanding and ends in a lasting partnership. We break complex engineering into four clear, controllable stages — so at every step, customers can see the progress and hold on to the result.
- 01
Consult & assess
Understand the production line, control architecture, and electrical requirements; define scope, constraints, and acceptance targets.
- 02
Engineering design
Design the control, drive, and power-distribution solution around the customer process, with documentation for installation and acceptance.
- 03
Commissioning & integration
On-site installation, system integration, signal and communication verification, and process commissioning to production readiness.
- 04
Lifecycle service
Operator training, maintenance support, troubleshooting, and long-term technical service for stable, continuous production.
Engineering in the field
Our work is measured on the plant floor. From drive cabinets to live production lines, these are real Huaxin Minfu engineering sites — designed, integrated, and commissioned by our own team.
Paper machine & winder sites
Wide, high-speed paper machines and winders under Huaxin Minfu drive and control — running steadily on the customer floor.
Drive & control cabinets
Common-DC-bus drive cabinets built around all-digital AC inverters, wired and commissioned on site.
PLC & MCS integration
Plant-level control systems engineered and brought online — the nerve center of every line we deliver.
On the plant floor
Drive and control systems running on the customer floor — from design and cabinets to on-site commissioning.

Insights
Notes from the engineering bench — how we think about drive architecture, sectional control, and tension regulation on demanding production lines.
Why our drives share a common DC bus with regeneration
On a winder or a sectional paper machine, braking energy is too valuable to waste as heat. A shared DC bus lets every drive section return that energy to the grid instead.
4 min readHolding constant tension on a high-speed double-drum winder
Our double-drum winder drives run at 1500 m/min. As the roll builds, its radius and inertia change — constant-tension control is what keeps the web stable from empty core to finished roll.
5 min readSpeed-chain control and load sharing on a sectional paper machine
A sectional paper machine is many drives that must behave as one. Speed-chain control keeps the draw constant; master/slave load sharing keeps the torque where it belongs.
5 min readOur three-level drive control architecture
Field drives, a control core, and an operator layer — three levels, one coordinated machine. Here is how we structure drive control for a wide, high-speed line.
4 min readWhy we use a 12-pulse rectifier on wide paper machines
A big common-DC-bus line fed by one rectifier can pollute the supply with harmonics. A 12-pulse front end is our standard answer for wide, high-speed machines.
4 min readLoad sharing that adapts to the grade
On our paper-machine drives the master/slave load-sharing ratio is not fixed — it follows grade, basis weight, speed, wire tension and vacuum automatically.
4 min readThe three functions a winder drive must get right
Unwind tension, rider-roll pressure, reversible control — three functions our high-speed winder drives perform to keep the roll clean.
4 min readSetting winding hardness with bottom-roll torque difference
On a double-drum rewinder the two bottom rolls do not share torque equally. The difference between them is what sets how hard the finished roll winds — and it has to track the building roll.
4 min readThe standards our drive systems are built to
Every drive and MCS we deliver is engineered against the GB and IEC standards that govern electrical terminology, EMC, rotating machines and low-voltage switchgear.
