The blades produced by Jinderui are all made of high-quality and suitable steel according to the production conditions and requirements of customers, and are made by a specific heat treatment process and ultra-high-precision processing equipment. The goal is to achieve the best balance between production performance and cost-effectiveness of the inserts.
Our thinnest blade has cut aluminum strips with a thickness of 0.02mm, and a blade with an outer diameter of 360mm has cut 90 strips. The maximum thickness of 25mm hot-rolled coil can be cut, and it has unique smelting steel and key production technology in the shearing of high-strength steel. Our blades are used in various applications such as cold-rolled steel strip, hot-rolled steel, silicon steel, copper, aluminum, nickel strip, etc., and have achieved extremely high service life, achieving higher cost performance and core competitiveness for customers.
he spacer is an important part of a set of precision tools. Its main function is to determine the length and adjust the gap. It has sufficient hard-ness and stability. The precision tolerance must be kept at the same level as the rolling scissors. The spacers produced by TENGDI are made of high-quality steel, with specific heat treatment and anti-corrosion treatment. To ensure stable and durable, the same precision tolerance standard as the rolling scissors blade. The user can easily adjust the gap between the upper and lower blades to achieve perfect cutting effect and dimensional accuracy
The appearance of gaps refers to the phenomenon that the welds are not bonded together. The length of the gaps is generally more than a few centimeters or even longer. The main reasons are as follows:(1) Pass wearAs the extrusion roll hole pattern wears, the hole pattern (R) size gradually becomes l
Sand-hole pipes are also a kind of quality accident caused by weld leakage, but their gaps are very small, some of them cannot be directly observed by human eyes, and must be found through testing equipment, so we call this kind of pipes sand-hole pipes. The main reasons for sand hole pipes are as f
(1) The hole type does not matchThere are two-roller, three-roller and four-roller weld seam extrusion structures. As long as the combined hole shapes do not match, it is easy to cause scratches on the surface of the tube blank, especially the two-roller structure.There are many factors that cause t
