In order to choose a suitable straightener, we must have a clear understanding of the principle of straightener, straightener machine is the extrusion of uneven metal sheet through upper and lower rolls to a certain thickness of strip or metal sheet, so as to achieve the effect of leveling, There are many kinds of straighteners in our company, their basic principles are the same, We divide all kinds of straighteners according to the thickness of materials, in stamping automation production, our straightener is mainly divided into BTL Heavy straightener, TL straightener, DL /BSL Precision straightener.
Here are the differences between these different types of straighteners:
1. BTL Heavy straightener
straightening material’s thickness is 0.5-6.0mm of BTL Heavy straightener, width is 0-1600m,It is suitable for the straightening of thick plate material, high strength plate, and the straightener machine of thick plate has a wide range of applications, it can process thick plate and high strength plate which cannot be processed by ordinary stamping production line, it is mainly applied to the leveling of thick plate materials such as automobile hardware fittings, fastening fasteners and caster hardware fittings before stamping.
This straightener is suitable for straightening thick plates of thickness 0.5-6.0mm
2. TL straightener
TL straightener is suitable for materials with thickness of 0.35-3.2 mm and width of 0-1600 mm, The main function is to straightening the metal sheet before blanking, eliminating excessive arcing of materials, and ensuring the normal and smooth process of stamping production（Remark: if there is no special requirement for straightening quality about steel plate）
This straightener is suitable for straightening metal plates with thickness of 0.35-3.2mm
3. DL thin sheet straightener
thin sheet straightener can be divided into two-stage straightener and single-stage straightener machine, two-stage straightener is suitable for thickness of 0.1-0.6mm,single-stage straightener is suitable for thickness of 0.1-0.5mm,width of two kinds of straightening materials ranges from 0 to 300 mm, and roller diameter is 20mm（25 straightening rollers, arranged in Up 3/down 3+Up 9/down 10),it mainly applied to straightening of thin sheets before stamping such as mobile phone accessories, computer accessories, digital products accessories etc.
DL and BSL straightener machine
DL two-stage precision straightener is suitable for straightening thin plates with thickness of 0.1-0.6mm and DL single-stage straightener is suitable for straightening thin plates with thickness of 0.1-0.5mm
