Production process in Poladan Saze factory

In order to know why being an manufacturer of industrial nuts and bolts in Tehran requires expertise, you must get to know the production processes. In Poladan Sazeh factory, the following steps are taken:

Wire preparation and cutting

The first step is to choose the right wire. The wires are phosphated and sized to prepare for forging operations. Accuracy in wire diameter is very critical for an industrial screw manufacturer and bolt master in Tehran.

Forging

Forging or shaping can be done by cold or hot method. Cold forging is usually used for small and medium size screws, which has high production speed and excellent surface quality. But for large sizes, which is the specialty of manufacturer of industrial bolts and master bolts in Tehran, hot forging is used. Poladan Sazeh is equipped with induction furnaces and powerful impact presses for hot forging.

Rolling

Threading is usually done by rolling method. In this method, there is no filing and the steel fibers are not cut, but shaped. This makes the thread stronger. Every manufacturer of industrial bolts and master bolts in Tehran who claims quality must use the rolling method, and Puladan Sazeh uses the most modern rolling machines.

heat treatment

This stage is the beating heart of production. To achieve the desired hardness and tensile strength (e.g. grade 10.9 or 12.9), bolts must be hardened. Industrial bolt manufacturer and bolt master in Tehran must have precise continuous furnaces so that the mechanical properties are uniform in all parts. Poladan Sazeh has an advanced quench and temper heat treatment line.

Coating and plating products

One of the main challenges of connections is corrosion and rust. An industrial screw manufacturer and bolt master in Tehran must provide various solutions to protect parts. Poladan Sazeh offers the following types of covers:

• Cold galvanized: for normal environments.
• Hot Dip Galvanized: which has a very high resistance in humid and acidic environments and the main expertise of industrial screw manufacturer and bolt master in Tehran is for outdoor projects.
