Screw Machine China
FMT China is  one of the leading screw making machine manufacturers and suppliers in China.
Screw machines, also known as automatic screw machines, are mechanical devices designed for the efficient and automatic production of screws, bolts, and other threaded fasteners,also includes fastener testing,inspectation,counting,sorting,bagging and packing after screws,bolts,rivet and nuts made. These machines are specifically engineered to perform various operations such as cutting, shaping, and forming metal stock into precise screw shapes.

Screw machines are typically classified into two main types: screw making machines and supporting equipments.
1. screw making machines: here are some types of screw making machines commonly available:
1). Nut bolt making machine
2). cold header machine
3). cold forging machine
4). automatic thread rolling machine
5). Open die header machine
6). self drilling screw drill machine
7). automatic nut tapping machine
8). cold forming machine

2. screw manufacturing supporting equipments: There are several supporting machines and equipment used in screw manufacturing processes. Some of the common ones include:
1). Thread rolling machines: These machines are used to create threads on the screws by applying pressure and rolling them between two dies. Thread rolling machines offer high production rates and produce threads with excellent strength and uniformity.
2). Wire drawing machines: Wire drawing machines are used to draw metal wire from a larger diameter to a smaller diameter. In screw manufacturing, these machines are used to produce the initial wire that will be further processed to create the screw.
3). CNC machines: Computer Numerical Control (CNC) machines are versatile machines that use computer programming to control the movement of tools. In screw manufacturing, CNC machines are used for various operations such as milling, drilling, and tapping to shape and create screw features.
4). packing and bagging machines: packing machines are efficient and reliable way to package screws and other fasteners. This machine can count, sort, and bag screws quickly and accurately.
5). Polishing machines: Polishing machines are used to give the screws a smooth and shiny surface finish. These machines use rotating brushes or polishing wheels with abrasive compounds to remove any imperfections or burrs on the screws.
6). Inspection and sorting machines: These machines are used to inspect and sort the manufactured screws based on their dimensions, quality, and other specifications. They use sensors, cameras, and other measurement tools to ensure that the screws meet the required standards.
7). Heat treatment equipment: Heat treatment processes such as annealing, hardening, and tempering are essential for improving the mechanical properties of screws. Heat treatment equipment, such as furnaces and quenching tanks, is used to subject the screws to controlled heating and cooling processes.
These supporting machines and equipment play a crucial role in the efficient and precise production of screws, ensuring that they meet the required standards and specifications.
8).Vibrating bowl feeder:A Vibrating Bowl Feeder is an effective way to feed a variety of materials. It can be used to feed screw,bolt,nut and rivet parts, components, or products of various sizes and shapes.

Overrall, Screw machines use various tools such as cut-off tools, threading tools, and chamfering tools to shape and finish the screws. They are equipped with automatic material feeds, coolant systems, and other features to ensure efficient and accurate production.

screw machines are crucial in industries where high-volume screw production is required, such as automotive, aerospace, and construction industries, as they offer increased speed, precision, and consistency compared to manual screw production methods.
