FASTENERS

 


  • MANUFACTURING PROCESS Of FASTENERS

A highly proficient quality control team checks a product for functional reliability, specifications, durability, and aesthetics. We have established robust and rigorous inspection processes to guarantee the quality of Boltsman’s fasteners —nuts, bolts, screws, rivets, and more. The inspection is done at each stage of fastener manufacturing. The process includes:

  • Heading process (cold forged): The cold heading process uses high speed automated “cold-headers” or “part formers.” The cold heading process is volume specific and it uses dies and punches to convert a specific “slug” or blank of a given volume into a finished intricately shaped part of the exact same volume

  • Slotting process : This is a milling process that uses a mill to cut a narrow ridge into the surface of a work piece

  • Threading process : The process is applied to the bottom of the work billet—the side without the head. Known as “thread rolling,” it’s a bulk deformation process. This type of cold-forming process is used because cylindrical parts—such as the remaining round part of the bolt—can easily have thread applied by rolling the work billet through two dies

Additionally, Company has also put in place a proper plating cycle that ensures plating quality and also makes sure that thickness is maintained.

Process Description

1.  Acid Pickling
Before the wire rod is drawn, the raw material must be cleaned in an acid pickling tank to dispose of the build-ups of rust and oil on the surface of the wire rod thus increasing the efficiency of the drawing and forming processes.

2.  Wire Drawing
The wire rods are converted into the desired length by drawing them through series of successively smaller dies.

3.  Heading and Forming
The slugs of drawn metal wire are then fed into forming machines which shape it into a threadless bolt.  The head of the bolt is formed and precision trimmed by a single die cast.  Each of four different forming machines are equipped with a set of various sized casts.

4.  Rolling
The rolling, or threading, of the bolts is done automatically by one of four various sized rolling machines.

5.  Degreasing
Since oil is used as a lubricant during the forming processes, the bolts must under go a degreasing process.  This is done to prevent rust from occurring and to prepare the bolt for further treatment processes.  The recovered oil may be used again.

6.  Passivating
Stainless steel bolts, often darken during the forming process and must, therefore, undergo passivation treatment in order to restore the finish.

7.  Heat Treating
The bolts then undergo a heat treatment process to increase their tensile strength.

8.  Galvanizing
Finally the bolts are galvanized which prevents rust from adhering to the surface.
