模具被誉为“百业之母”，是在外力作用下使坯料成为有特定形状和尺寸的制作的工具。
模具是精密工具，形状复杂，承受坯料的胀力，对结构强度、刚度、表面硬度、表面粗糙度和加工精度都有较高要求，模具生产的发展水平是机械制造水平的重要标志之一。
不锈钢焊管模具,也叫轧辊、辊扎，是生产不锈钢管必不可少的工件，其价值对于制管设备而言，是有过之而不及，只有做工精良的模具才能够生产出的管材。
焊管模具不仅是带动不锈钢焊管设备的主要枢纽，同时也是决定不锈钢管形状以及尺寸的主要配件。
焊管模具的种类有圆管模、方管模、梅花管模、椭圆管模、扇形管模、八方管模等等。
优良的焊管模具通过选用上等原材料及精湛成熟的加工技艺，可以做到精度高、误差小，解决管材形成面不平、角度不好、制作过程中产生的拉伤、起皱、指纹、机械纹、对角、凹角等缺陷，并使形位公差圆度控制在±0.05mm以内，方管对角误差不超过±0.05mm.
Molud known as the "100 industry mother", is in the external force under the blank to become a specific shape and size of the production of the tool. The mold is a precision tool, the shape of complex, bear the blank of the expansion force, the structural strength, stiffness, surface hardness, surface roughness and processing accuracy have a higher demand for mold production level of development is one of the important indicators of the level of machinery manufacturing.
Stainless steel pipe mould, also known as roll, pipe die, is the production of stainless steel pipe essential parts, the value of the pipe system equipment, there is no time, only the workmanship of the mold to be able to produce first-class pipe. Welded pipe mold is not only the main hub of stainless steel pipe equipment, but also determine the shape of stainless steel tube and the size of the main accessories. The types of pipe molds are round tube mold, square tube mold, plum tube mold, oval tube mold, fan tube mold, P Plus tube mold and so on. Excellent pipe mold through the selection of fine raw materials and superb mature processing techniques, you can do high precision, small error, to solve the formation of pipe uneven, the angle is not good, the production process of the strain, wrinkling, fingerprints, mechanical pattern , Diagonal, concave angle and other defects, and the shape and position tolerance roundness control within ± 0.05mm, square tube diagonal error does not exceed ± 0.05mm.
