There are many methods and technologies for producing a fastener. For example, cold forming, hot forging, machining of cold drawn bars, zinc die casting and injection molding. Each of these methods has its own unique advantages and applications.
Cold forming is a common technique for bolts and screws in sizes M1 to M24 in diameter. This methodology is also used in producing nuts sized from M3 to M16. Other factors, such as the end application of a fastener, economic order volume and cost, need to be considered when selecting a production method.
No matter which production method is selected, it involves a series of production steps that have a significant impact on the quality and performance of a fastener.
At Bossard we have strict manufacturing selection criteria and in-process control.
In-process control is the most efficient way to ensure that product quality is in accordance with the requirements. Every production step is monitored throughout the production process and deviations are identified and corrected almost instantly. The result is less risk, higher quality and timely delivery.
