Production Process
1,The six technical features of our company's production of micro-channel aluminum flat tubes：
1),High-quality cast rod: our micro-channel flat tube aluminum rod filter 40 mesh + 0.09 ~ 0.13, but generally 20 mesh + 0.2
2),High requirements for zinc spraying: the amount of zinc layer is 6-8g / ㎡, but the general spraying fluctuations are large
3),Online Flaw Detection: Requires Online Flaw Detection
4),Large extrusion ratio: our extrusion ratio is greater than 427, which is more than 8 times higher than conventional extrusion ratio (50)
5),Ultra-high dimensional accuracy: The accuracy requirement is ± 0.03, which is more than 8 times higher than the international high-precision level
6),High air tightness requirements: Product defects are measured by PPM, which is 200 times higher than traditional% requirements
2, The main production process of micro-channel aluminum flat tube:
Aluminum rod heating extrusion --- zinc spraying --- rewinding --- flaw detection --- reshaping& cutting --- inspection packaging
