There are steps in the manufacturing process of the spanner tool. They are - 1. Forging, 2. Moulding, 3. Trimming, 4. Milling, 5. Tempering, 6.

A drop forging process is well suited to produce products such as spanners, pliers and puller yokes. Heated raw material is transformed at high speed in a 

NVR offers wide range of Spanners, forged from high grade Chrome Vanadium Steel using the latest production methods. NVR Spanners made to DIN, ANSI and ISO standards meets the latest requirements of screw - joint engineering.

Most types of spanner are made using the drop forging process. Steel rods are cut into short lengths, called billets, and each one is passed through an induction heating coil which uses electromagnetism to heat the metal to about 1000 degrees Celsius.

At present, there are two kinds of wrench spanner manufacturing processes: one is casting, the other is wrench spanner forging process. Is Spanner / Wrench Cast or Forged? 1, Spanner wrench casting process Melt the bar into liquid state, then pour it into the die cavity with spanner shape, and wait for it to solidify to form a complete spanner.

The manufacturing process of a spanner hand tool is a very long, detailed, and very minutely-planned process. Every step deserves careful supervision by expert technicians overlooking the work of the team of highly-skilled workers to ensure that the entire manufacturing process of the spanner tool is quick, efficient and safe while yielding the best results for the invaluable

The present invention relates to a method of manufacturing a wrench. Specifically, from the manufacturer′s perspective, the effect of improving the reliability of the product leads to an effect of increasing sales, and from the consumer′s perspective, costs incurred to repurchase the product due to the breakage of the wrench can be reduced.
