flat die for screw and bolt thread making machine

What is a screw flat rolling die?

Flat die is an essential tools of a thread rolling machine, flat die machine, screw thread making machine,and bolt thread making machine used for thread forming. It is used to create a continuous thread on a shank or other blank material. The flat die is made from high-grade alloy steel and is designed for long time. It has a smooth surface that ensures the threads roll without any issues. Additionally, the flat die has been designed to be used with a variety of different sized shanks and materials. This makes it incredibly versatile and useful for many different uses.  

External threads are rolled onto cylindrical workpieces using a flat die, which is used in screw thread rolling machines. It is made up of a circular, flat plate with spiral grooves carved out of it. The desired thread pattern matches the grooves' dimensions and pitch. The material flows and takes on the thread shape when the workpiece is pressed up against the rotating die.

FMT China Flat dies are commonly used in flat die thread rolling machines for generating threads on various materials, including steel, aluminum, and brass. They can be customized to produce different thread sizes and profiles according to specific requirements.

It is essential to choose the right die material and design based on the workpiece material, thread specification, and desired quality. The hardness and surface finish of the die play a significant role in ensuring accurate and durable thread rolling operations.

A FMT China flat die for a screw thread rolling machine is a vital component that enables efficient and cost-effective thread production in various industries, such as automotive, aerospace, and construction.

 Advantage and disadvantages of flat die

The use of flat dies in thread rolling has several advantages. It is one of the oldest processes for cold forming threads, providing durability and reliability. The thread is formed within one working stroke, making the process efficient. Flat die thread rolling machines are widely used in industries where high-quality threads with precise dimensions are required, such as automotive, aerospace, and construction.
