Cold drawing is a process that deforms metal at room temperature, usually with a die to reduce the diameter of the rod. It can also change the shape of the cross section of the alloy.
When chatter happens, it leaves undesirable ring marks on the inner and outer surfaces of the tube. These defects don’t meet geometric specifications and must be cut out or discarded.

During the cold drawing process, metals are drawn down to smaller diameters without heating them. This is done using a drawing machine, wire and lubricant. It can be a wet or dry draw depending on the type of lubrication used.
The tensile strength and yield strength of the alloy increases while its plastic properties decrease during drawing. This dependence is a result of the cold working process and is different for each alloy. These dependences are evaluated experimentally through a number of methods including tensile tests and modeling.
Horenco’s new line of swaging, auto cold drawing and straightening machinery is designed to make the lives of manufacturers and fabricators much easier. Our new machines are packed with top-of-the-line features that will save time and money, while also improving the quality of your final products.
Modern electrical wiring on a drawing machine uses high-speed data buses that carry hundreds of signals over a single pair of wires instead of dozens of control wires between motor drives and the PLC. This greatly reduces the amount of wire needed and saves you time and money on electrical bills.
For safety, many modern drawings machines feature fast stop and numb stop options. Fast stop cuts off power to all brakes instantly, while numb stop allows the draw block to continue at a controlled rate until the operator stops the machine with a mechanical brake lever. Both of these options reduce the risk of injury or damage to the equipment.
It’s Easy to Operate
The Auto cold drawing machine takes raw steel wire rod and reduces its diameter until the desired size is achieved. This is a crucial machine in the production process of steel wire and metallic mesh.
Modern drawing machines use modular design, allowing them to be configured for specific products and wire sizes. This allows for fast string up time and easy maintenance. They can also be configured to support direct die cooling, which is a must for higher-carbon wire such as pre-stressed concrete stand and rope wire.
Some machines also employ a Morgan B block as their final drawing block to provide accumulation time that enables spool changeover while the machine continues to draw wire. This feature also makes it easier to swap out die cassettes, since the cassettes are directly positioned over the block instead of up and down a sheave. This eliminates the need to disconnect wire from the sheave. Additionally, the block can be directly cooled with a water cartridge instead of using an indirectly-cooled motor, which is less expensive and more convenient.
It’s Easy to Maintain
Horenco’s new line of swaging, cold drawing, and straightening machines is perfect for manufacturers looking to make their processes faster, more efficient, and higher quality. These turnkey machinery are designed to reshape metal bars, ensuring that they’re the right size and shape for use in various industries.
Drawing machines are easy to string up and operate. They typically use a series of die/capstan combinations to reduce wire diameters. The speed of the capstans and the synchronization of their speeds is critical to achieve proper diameter reduction steps.
To avoid any damage to the wire, wet the surfaces of the dies and pulling capstan with a suitable drawing lubricant. This minimizes slippage between the capstan and wire, which can produce heat and result in short final lengths. Some systems also require forced air-cooling of the capstans to prevent overheating. However, this method is expensive and energy-intensive to operate. It’s advisable to critically examine the need for forced air cooling on a drawing machine before specifying it.
