Production Detail Diagram
01
Laser cutting and tube cutting
Laser Cutting for Sheet Metal：Laser cutting for sheet metal utilizes a high-energy laser beam to instantly melt or vaporize materials, delivering micron-level precision via computer control
Laser Tube Cutting：Laser tube cutting handles round, square & special-shaped metal tubes. Its 360° rotary & 3D cutting enables precise hole punching, beveling & hollowing
02
Bending, rolling, punching
Bending：It can process metal sheets with a thickness ranging from 0.5mm to 20mm, and the angle error is controlled within ±0.5°.
Roll Bending：Our equipment rolls plates 3-100mm thick and up to 3000mm wide. Progressive rolling eliminates stress, ensuring <1.5mm roundness error
Punching：The equipment supports metal sheets with a thickness of 0.1 - 12mm. It can achieve high-speed stamping over 500 times per minute with a hole diameter accuracy of ±0.1mm
03
Welding (robot welding and manual welding)
Intelligent welding robots, coupled with the integration of an automatic feeding machine and a cutting machine, enable highly efficient and stable welding operations. Committed to sustainable production practices, we've implemented a state-of-the-art smoke and dust purification system in compliance with national environmental protection standards.
04
Machining
The company introduced advanced machining equipment integrating cutting-edge tech. These machines can process multiple surfaces in one clamping, improving part accuracy (±0.001mm error) and efficiency while reducing errors from repeated clampings.
05
Acid pickling, phosphating, shot blasting
Acid Pickling：Utilize hydrochloric or sulfuric acid solutions to dissolve rust, oil, and oxide layers, activating the metal surface. Precise control of temperature (50-70°C) and time (5-15 min) prevents over-corrosion, suitable for carbon steel, aluminum alloy, etc
Phosphating：Pickled workpieces are immersed in zinc/iron phosphating solution. A 1-3 g/m² nano-porous film forms via chemical reaction, boosting surface roughness, coating adhesion, and offering basic rust protection
Electrophoretic Coating：Phosphated workpieces act as electrodes in a water-soluble paint tank. Electric fields drive particle deposition, creating 15-30μm films. UF and Anode Cell systems keep the paint stable, ensuring even coating and ≥1000-hour salt spray resistance.
Shot Blasting Process：Shot blasting uses a high-speed impeller (60-120m/s) to propel steel shots and cast steel sands onto workpieces. The impact removes oxide scale, rust, and old coatings, creating a rough surface for better coating adhesion.
06
Paint and powder coating
Utilizes highly integrated smart gear like the KJ264 robot painting workstation and Wagner manual wet spray system to build a human-machine collaborative production line. With rich experience and precise process management, it gains customers' unanimous approval.
07
quality testing
The quality inspection process ensures products meet design standards and industry regulations through full-process, multi-dimensional inspection methods. By integrating visual inspection, non-destructive testing, physical-chemical analysis, and automated inspection equipment, it achieves zero tolerance for defects and quality traceability.
08
assemble
Assembly operation：Assembly must follow process specs. Inspect appearance, dimensions and performance post-assembly to ensure quality and boost efficiency.
09
Packaging and Shipping
For packaging and shipping, balance protection and efficiency. Use standardized packaging, automation, and logistics coordination to standardize operations, reduce cargo damage, and ensure timely delivery
