A Vertically Integrated Industrial Manufacturer
IVOLTECK masters advanced forging technologies — precisely controlling metal flow and deformation to form complex geometries with minimal tolerance. That same engineering depth extends from die-forged components to advanced-material rail-transit parts and complete energy-storage systems.
We keep the entire chain in-house: our own molds and tooling, heavy die-forging lines, heat treatment, precision machining and a comprehensive testing lab — a closed loop from raw material to finished, certified part.
Three Major Business Units
One integrated manufacturer serving commercial vehicles, rail transit and the energy transition.
New-Process Die-Forged Components
High-precision die-forged, heat-treated and CNC-machined metal parts for mission-critical, load-bearing applications.
- Chassis load-bearing parts, front axles, steering knuckles
- Power-transmission line fittings, couplings, terminals
Advanced-Material Rail-Transit Parts
Friction and structural components engineered from new materials — including brake shoes co-developed with Germany's BREMSKERL.
- Low-wear, heat-stable friction formulas
- Wheel-tread protection, longer turning intervals
Industrial & Commercial Energy Storage
Liquid-cooled C&I energy-storage systems with intelligent optimization and modular, space-saving integration.
- Time-of-use arbitrage & backup power
- AGC frequency regulation, unit self-balancing
Engineered for High-End Equipment
Core advantages that meet the stringent precision and reliability requirements of demanding industries.
High-Precision Metal Forming
Advanced forging precisely controls metal flow and deformation, forming complex geometries with minimal dimensional tolerance.
Strength Under Extreme Conditions
Optimized microstructure sharply raises mechanical properties and fatigue resistance for high-temperature, high-pressure service.
Full-Lifecycle Durability
Durability is assessed early via simulation and test data, eliminating internal defects to extend service life and cut maintenance cost.
Customized Technical Solutions
From material selection to process design, we deliver forging solutions tailored to each customer and industry challenge.
Commercial-Vehicle Chassis
Front axles, steering knuckles and balance-bridge brackets — backed by 4000 / 1600 / 630-ton forging lines and a high-precision CNC cluster.
Bogie Support Seats
Couplers, suspension and connecting parts — verified by CMM, metallographic and magnetic-particle inspection, certified by CRRC.
Railway Track Components
Turnout components, fastening systems, metal pads and fishplates — with in-house molds and tooling for small-batch, urgent orders.
Power-Industry Forgings
Line fittings, insulator caps, valves, pipe fittings and terminals — closed-loop from forging to precision machining.
Rail Braking, Reengineered
Brake shoes for locomotives, passenger cars and freight cars — built from new friction materials and validated to the highest safety standards, in partnership with Germany's BREMSKERL.
Braking Safety & Reliability
Validated with BREMSKERL on a 1:9 braking test bench — including a 250 km/h environmental chamber with wet/slippery simulation — for stable friction, heat-fade resistance and controllable braking distance.
Low Wear, Lower TCO
A low-wear formula extends replacement cycles; excellent thermal conductivity protects wheel treads, extends turning intervals and reduces total lifecycle cost.
Selection & Customization
Full physicochemical characterization (COF, wear rate, hardness, density) on customer samples, with the optimal formula recommended and customized R&D to de-risk selection.
Liquid-Cooled C&I Energy Storage
Serving industrial and commercial users, our systems apply to power energy storage, backup supply, peak shifting, peak shaving, frequency regulation and microgrids — generating revenue from time-of-use tariff spreads while stabilizing grid output and supporting renewable power stations.
Customized R&D, Concept to Part
An excellent tooling R&D team runs the full loop — no reliance on external suppliers — with a collaborative CAD · CAE · CAM workflow that shortens new-product lead times.
In-depth analysis of customer requirements
Tooling customization & optimization
Selection of suitable material properties
Establishment of a rapid-response mechanism
Small-batch prototyping & validation
CAD Design
3D mold-flow and cooling-system planning with optimized mold geometry — a precise data foundation for manufacturing.
CAE Analysis
Simulation of metal plastic forming predicts material flow, stress and potential defects, avoiding repeated mold trials.
CAM Machining
Design data is converted directly into CNC instructions so high-precision machines consistently meet GD&T specs.
Full-Process Quality Inspection
Raw-Material Intake Testing
Every incoming material passes rigorous physical and chemical testing before it enters production.
In-Process Non-Destructive Testing
NDT detects micro-cracks, pores and hidden defects inside components at key manufacturing stages.
GD&T Dimensional Verification
High-precision instruments verify every dimension against strict GD&T standards.
Final Pre-Shipment QC
A closed-loop final inspection — visual and functional — before delivery, from raw material to finished product.
Certified for Global Business
Products are further adapted to the specific railway-industry standards of each country and region — and, for rail-transit braking, co-developed with Germany's BREMSKERL — easing market access and mitigating international-trade technical barriers.
50+ Strategic Partners
Covering all major commercial-vehicle manufacturers.
After-Sales Service System
A closed-loop service model built around overseas clients — from localized solutions to continuous improvement.
Diversified, Localized Solutions
Solutions tailored to local language, culture and business practice — removing communication barriers and building trust.
Rapid-Response After-Sales
Standardized procedures ensure a fast response to quality issues and best-fit solutions, minimizing downtime.
Technical Support Team
Overseas support staff are regularly trained in product knowledge and skills to resolve complex issues on the ground.
Continuous Optimization
Client feedback drives a closed-loop improvement of service processes, support strategy and overall satisfaction.
