The full-chain precision manufacturing system

Yunliang has established a complete manufacturing system covering raw material cutting, precise forming, intelligent welding, surface treatment and final packaging.
With 13 core processes closely linked together, it enables the full-process autonomous and controllable production of off-road modification parts from raw materials to finished products.
From high-precision CNC machining to automated anti-corrosion spraying, from strict structural forming to meticulous hand polishing, each process adheres to the quality control standards of the main manufacturer.
This ensures that the products fully meet the requirements in terms of strength, precision, durability and adaptability, providing reliable, stable and long-lasting core equipment support for extreme off-road scenarios.

High-Precision Laser Cutting Technology

Yunliang adopts imported high-power laser cutting equipment to achieve ultra-high machining accuracy up to 0.01mm. It can precisely cut various special plates for off-road modifications such as high-strength carbon steel and aluminum alloy.
All blanks of our products, ranging from competition bumpers and chassis skid plates to customized kits, are processed by laser cutting. This ensures dimensional accuracy, smooth edge finish and structural integrity of products from the very beginning, laying a solid foundation for subsequent processing and guaranteeing perfect fit between modified parts and original vehicles.

Automated Finished Product Packaging Process

The fully automatic sealing machine serves as the final core production procedure at Yunliang, handling standardized packaging for finished off-road modification parts.
Automated packaging delivers all-round protection against moisture, scratches and collisions, preserving product integrity during transportation and storage.
Every product is delivered to customers in flawless condition, with quality safeguarded all the way from factory shipment to installation.

Full-process Workpiece Cleaning Process

Industrial-grade high-pressure cleaning equipment performs deep cleaning procedures for workpieces after machining and sandblasting.
Adopting high-pressure spraying and ultrasonic cleaning, it thoroughly removes oil stains, impurities and dust on workpiece surfaces.
This safeguards product quality during painting and assembly, eliminating impurities that impair coating adhesion and assembly precision.
Every workpiece proceeds to the next process in a spotless condition, enabling rigorous quality control down to every detail.

Surface Pretreatment Sandblasting Process

Professional automatic sandblasters handle the core pretreatment process before coating.
High-pressure sandblasting removes rust and oxide scale and roughens workpiece surfaces.
It thoroughly cleans parts while boosting coating adhesion, enabling firmer and longer-lasting anti-corrosion layers in subsequent painting.
This fundamentally improves the anti-corrosion performance and service life of products, ensuring outstanding durability even under extreme environments.

Precision Hand Finishing Technology

Manual polishing by professional technicians is a vital guarantee of Yunliang’s craftsmanship quality.
For workpieces after welding and machining, precise hand grinding removes welding burrs, smooths edges and refines surface details.
Each product combines robust structural strength with exquisite appearance. It not only improves visual texture but also eliminates safety hazards caused by sharp edges, realizing dual upgrades in workmanship and aesthetics.
Our products deliver both outstanding looks and reliable performance to satisfy all off-road application demands.

Precision Press Forming Process

High-precision vertical presses carry out precise press-fitting, shaping and assembly procedures for components.
For core parts including shock absorbers, chassis kits and suspension systems, precise pressure control enables tight press-fitting and structural calibration of parts.
This guarantees assembly accuracy and structural stability, extends service life and boosts reliability.
All modification kits maintain stable performance during long-term off-road use.

High-Precision CNC Bending Process

CNC bending machines precisely perform multi-angle bending forming of various plates, serving as a key process for manufacturing protective bumpers, chassis kits, body accessories and other products.
The CNC system accurately controls bending angles and depths to ensure dimensional accuracy and structural consistency of every product, enabling seamless perfect fit with original vehicles.
Meanwhile, it optimizes product structural strength, so the modified parts resist deformation and cracking even under extreme working conditions.

Heavy-Ton Hydraulic Stamping Process

Heavy-tonnage hydraulic presses are core equipment for Yunliang to manufacture high-strength off-road components.
For core parts such as competition bumpers, chassis skid plates and chassis lift kits, they carry out stamping, drawing and forming procedures on high-strength plates.
Massive pressing force forms integrated one-piece structures, greatly boosting impact resistance and structural rigidity of products.
The components can easily withstand harsh off-road conditions including stone impacts and chassis ground strikes.

Professional Tube Forming Process

Fully automatic CNC tube benders precisely bend and shape tubes for various off-road protective bumpers, roof racks and roll cages.
Bending angles and radii can be customized according to structural requirements of different vehicle models.
Without compromising tube structural strength, the finished parts achieve seamless fit with original vehicles, balancing protective performance and sleek appearance to meet modification demands for all types of hardcore off-road vehicles.

CNC Precision Machining Process

High-precision CNC lathes and engraving machines act as core equipment for precision machining at Yunliang.
They perform high-precision turning, engraving, drilling and other processes on core shock absorber components, customized decorative parts and complex structural pieces.
Machining accuracy reaches the micron level, meeting OEM-grade assembly standards while enabling personalized custom textures and shapes.
Every product delivers both reliable performance and attractive appearance.

High-Precision Laser Cutting Process

Professional industrial-grade metal band saws serve as the first core production process at Yunliang, performing standardized blanking of raw materials including various steel and aluminum alloys with high precision.
High-accuracy cutting delivers uniformly sized blanks with minimal tolerances for subsequent processing.
We control raw material quality from the very start, avoiding downstream processing defects caused by dimensional deviations of raw stock.
This ensures consistent production and structural stability of all off-road modification parts, supplying standardized blanks for follow-up manufacturing and securing uniform structure and production consistency of components from the source.

Automated Laser Welding Process

Equipped with professional automatic laser welding equipment, we adopt full and seamless welding for core off-road modification parts such as front and rear competitive bumpers, chassis reinforcements and roll cages, with weld strength far exceeding industry standards.
Dual quality control combining equipment processing and manual flaw detection thoroughly eliminates cold solder joints and missing welds.
Every welding joint can withstand impacts, vibrations and heavy loads under extreme off-road conditions, building a solid structural barrier for vehicle safety.

Full-process Automatic Anti-Corrosion Spraying Process

Yunliang has built a full-process automatic spraying production line, adopting the industry-leading dual anti-corrosion process of electrophoresis plus powder coating.
A dense anti-corrosion base layer is formed through electrophoresis first, followed by high-temperature powder coating to create a wear-resistant outer layer.
This dual-layer protection endows products with exceptional resistance to corrosion and scratches.
All products undergo strict quality inspections including salt spray testing and hardness testing.
They maintain intact appearance and stable structure for a long time even in harsh off-road environments such as muddy, saline-alkali, rainy and snowy conditions, staying in great shape for years.
