When it comes to manufacturing fasteners, the primary step is cutting. The respective raw material which is in the form of a round bar, in the length range of 12’ to 40’, is saw cut or sheared. When using a saw to cut, bandsaws that make use of saw blades are put to use so as to cut through the steel round bar. Consequently, when shearing, the raw material is chopped using the equipment. As compared to saw cutting, shearing is a more efficient process and is also less time consuming as well as cost-effective.
Moving further heading, also known as forging, is one of the oldest processes of metal working. This step involves shaping the metal by making use of localized compressive forces. Forging can be classified as hot forging, warm forging, and cold forging depending on the temperature at which the process is conducted. Usually, post forging, the forged parts have to undergo further processing to get finished part.
Next up is threading. As the name suggests, threading is the process used to create screw threads. There are a number of processes that can be used to create screw threads. Depending on a number of factors, the type of threading process is determined. These factors include the likes of finances, time, level of precision required, application of the final product, process equipment, etc. At Mac-Fit Industries, we make sure to follow the best practices to meet the specific industry requirements of our clients and comply with all industry standards for the same.
Hot Dip Galvanizing
The final step in the manufacturing of bolts, hot dip galvanizing involves surface coating for fasteners which helps in providing a strong and durable protection against corrosion. The process comprises of dipping the fasteners in a molten zinc bath. Post this, the fasteners are spun so as to get rid of the excess zinc on them followed by cooling them in water to solidify the zinc. This entire process ensures that bolts are corrosion resistant and solid in nature.
