The Ronen® Self Drilling Screw Cold Heading Machine forms the blank of self-drilling screws through cold heading, without the need for heating, greatly saving time and costs for manufacturers. This machine produces screw heads in a single operation. All you need to do is insert the metal wire into the feeding machine and set the screw size.
The Self Drilling Screw Cold Heading Machine directly rolls the wire into screws. It can shape the metal without heating, thereby continuously forming the drill tip and threads. This method can efficiently produce screws that can self-drill when in use.
The machine is equipped with specialized tools for creating the geometry of the drill tip. The shape of the drill tip is crucial as it determines whether the screw can penetrate metal or wood effectively without a pre-drilled hole. Its operation involves loading the wire and monitoring the output.
Using a Self Drilling Screw Cold Heading Machine to manufacture self-drilling screws can enhance the strength of the metal. The cold processing technique makes the screw shaft and the drill tip more resilient than those produced by mechanical processing. It can operate continuously, converting the wire into finished products, namely custom self-drilling screws.
Using the machine combines multiple steps into one. There is no need to first manufacture the screws and then add the drill tips separately. Instead, a complete self-drilling screw can be formed from start to finish through an automated process. It can form complex and intricate shapes. This machine uses multiple forming stations to gradually create the grooves and tip of the drill bit.

The core selling point of the Self Drilling Screw Cold Heading Machine is that it can produce the "drill tail" of the self-drilling screw in one operation, without the need for separate processing. The drill head and the head are concentric, and the screw will not twist when being tightened. Moreover, the cold-bent screws have high strength, and the drill head part is less likely to break.
