Points for Selecting Plate Thickness in Box Duct Manufacturing

Points for Selecting Plate Thickness in Box Duct Manufacturing

By controlling the selection of board thickness, it is possible to reduce costs as well as shorten delivery times! There are important points such as marketability and ease of acquisition.

In the production of box ducts, it is more efficient to manufacture using only 2.3t instead of fabricating with 1.6t and applying angle reinforcements, as this can shorten delivery times and reduce costs. In precision sheet metal processing, the thinner the material, the lower the processing costs due to material expenses. This trend is particularly strong with high-cost materials like aluminum and stainless steel. However, despite using the same material, thicker sheets can sometimes be cheaper due to factors like availability and ease of procurement. For example, with SUS304, a commonly used stainless steel, 3.0mm thickness is more readily available and cheaper than using 2.5mm thickness. 【Features】 ■ Cost reduction ■ Improved work efficiency ■ Further shortening of delivery times *For more details, please download the materials or contact us.
