There are several different types of cold heading machines, each designed for specific applications and production requirements. Here are some of the common types of cold heading machines:

Upsetter: An upsetter, also known as a forging machine, is a type of cold heading machine that is used to form parts by squeezing a metal billet between two dies. Upsetters are commonly used to produce parts such as axles, gears, and bolts.

Transfer header: A transfer header is a type of cold header machine that uses a series of stations to transfer parts between dies to form them into the desired shape. Transfer headers are commonly used to produce fasteners such as bolts, screws, and nails.

Progressive header: A progressive header is similar to a transfer header, but it uses a continuous feed of wire or rod stock to produce parts in a continuous process. Progressive headers are commonly used to produce high-volume parts such as pins, rivets, and clips.

Multi-station header: A multi-station header is a versatile cold heading equipment that can be customized to produce a variety of parts with different shapes and sizes. These machines use a series of dies and punches to form the material into the desired shape.

Nut former: A nut former is a type of cold heading machine that is used to produce nuts and other threaded parts. These machines use a series of punches and dies to form the material into the desired shape, including the threads.

Cold forging press: A cold forging press is a high-force machine used to form parts by applying pressure to a metal billet or blank. These machines are used to produce high-strength parts for the automotive, aerospace, and other industries.

Overall, cold heading machines offer a cost-effective and efficient way to produce high-quality metal parts with excellent strength and durability. The choice of machine will depend on the specific requirements of the application, such as the size, shape, and volume of parts needed.

Rather than selecting a fastener making machine only by model number, buyers should consider the finished part diameter, length, geometry, material, number of forming operations and required production output.

Selected Shinetop bolt former series cover fastener sizes up to M30 and product lengths up to 355 mm, depending on machine configuration.

WHAT EQUIPMENT IS USED IN FASTENER MANUFACTURING?

Fastener production may involve several manufacturing stages, depending on the finished product and material. For cold-formed bolts and precision components, the core process normally includes material feeding, cut-off, multi-stage forming and, where required, thread rolling.

Shinetop focuses on the cold forming and thread rolling stages of this process.

This allows buyers to select equipment around the actual fastener manufacturing process instead of treating every machine as an isolated production unit.

FASTENERS AND COLD-FORMED PARTS YOU CAN PRODUCE

One advantage of multi-station cold forming is its ability to produce more than one standard fastener shape.

Based on Shengtuo's existing machine range and displayed production samples, suitable applications can include:

Hex Bolts

Hex-head fasteners are one of the most important product categories for bolt forming equipment. Shengtuo's catalogue specifically includes HEX product size information across its bolt former series.

For manufacturers planning hex bolt production, machine selection should consider bolt diameter, total length, head geometry and required forming sequence.

This capability also supports a dedicated hex bolt making machine solution for buyers focusing specifically on hex bolt production.

Socket-Head Fasteners

The Shengtuo catalogue also lists socket-type fastener capability within the bolt former specifications.

Depending on the required geometry, different die and blow configurations can be evaluated.

Long-Shank Bolts and Components

Selected machine configurations support long workpieces, with product lengths reaching up to 355 mm on published 3-, 4- and 5-die series.

Special-Shaped Cold-Formed Parts

The actual production samples supplied by Shengtuo show a broad range of headed, stepped, hollow-looking, splined and special-profile components.

For these products, the forming sequence and tooling arrangement should be evaluated according to the finished drawing.

COMPARE FASTENER MAKING MACHINES BY FORMING CAPACITY

The following comparison provides a quick overview of Shengtuo's main fastener forming equipment. Exact specifications vary by model and should always be checked against the selected machine configuration.

ENGINEERING FEATURES FOR STABLE MULTI-STATION FORMING

Fastener manufacturing machine must maintain stable feeding, cutting, transferring and forming during continuous operation.

Shengtuo's machine structure includes several features designed around these requirements.

Automatic Wire Feeding

Automatic straightening and feeding equipment helps move the wire into the forming machine continuously.

Adjustable Transfer System

Transfer fingers move blanks between forming stations. Shengtuo's displayed system allows individual adjustment of the transfer fingers to suit the forming setup.

Cut-Off and Feed-Length Control

The cut-off system controls the blank supplied to the forming stations, while applicable configurations use digital adjustment to control the feed length.

Pneumatic Components and Machine Control

Existing Shengtuo machine materials show pneumatic control components and branded pneumatic/solenoid components used in applicable configurations.

IN-HOUSE MANUFACTURING BEHIND SHINETOP

The performance of a cold forming machine depends not only on its nominal forming force or number of stations. The machining accuracy and stability of the machine structure are equally important.

Shengtuo uses a range of in-house machining and inspection equipment for machine production, including:

Gantry machining equipment

CNC machining centers

High-precision inspection platforms

CNC boring lathes

Large lathes

Five-side machining centers

For machine-bed processing, Shengtuo states that one-setup machining helps control machining accuracy within 0.05 mm.

This machining capability supports the alignment and structural consistency required for multi-station forming equipment.

HOW TO SELECT THE RIGHT FASTENER MANUFACTURING EQUIPMENT

There is no single fastener making machine that is automatically suitable for every bolt or cold-formed component.

Before selecting a machine, buyers should evaluate the following factors.

1. Finished Part Diameter

Check the final fastener diameter and required wire diameter against the forming capacity of the selected model.

2. Part Length

Longer fasteners require sufficient cut-off, feed and kick-out capacity.

3. Head and Part Geometry

A standard bolt head and a complex multi-step cold-formed component may require very different forming sequences.

4. Number of Forming Operations

The required forming operations help determine whether a 3-, 4-, 5-, 6- or other multi-station configuration is appropriate.

5. Material

Material properties influence forming load, tooling and achievable output.

6. Required Production Output

The required parts-per-minute target should be evaluated together with part geometry and material.

7. Thread Requirements

If the component requires external threads, the required thread diameter, length and specification should also be used to select the appropriate thread rolling machine.

1. Core Process of Cold Heading

2. Significant Advantages of Cold Heading

In modern manufacturing, metal components such as fasteners, bolts, nuts, and rivets are widely used in industries like automotive, aerospace, machinery, construction, and electronics. To improve production efficiency, reduce material waste, and enhance part strength, cold heading forming machine play a crucial role as efficient and precise processing equipment. This article will focus on the principles, processes, and technological advantages of cold heading, helping readers gain a comprehensive understanding of this advanced forming method that replaces cutting with force.

Core Process of Cold Heading

The cold heading process generally includes the following main steps:

1. Raw Material Preparation: Suitable diameter metal rods are selected, straightened, cleaned, and lubricated to prepare for the subsequent forming steps.

2. Cutting to Length: The rods are cut into the required length blanks using mechanical tools, ensuring high precision and speed.

3. Initial Heading: The blank is placed into a mold cavity, and a punch applies high pressure to force the metal into the mold, creating a rough shape.

4. Multi-Station Heading (if applicable): For parts with complex structures, multiple forging operations are performed, such as pre-forming the head, extrusion of grooves, and pre-forming threads. Material automatically transfers between each station.

5. Part Ejection and Inspection: After forming, the workpiece is ejected from the mold. Some machines are equipped with in-line inspection systems to ensure consistent quality.

Significant Advantages of Cold Heading

High Efficiency

The cold heading forming machine operates at high speeds, producing hundreds of parts per minute, far exceeding traditional turning or milling methods. This makes it ideal for mass industrial production.

High Material Utilization

Traditional cutting processes remove a large amount of metal, causing significant waste. In contrast, cold heading forms the material through metal flow and extrusion, with almost no waste, achieving a material utilization rate of 85% to 95%.

High Strength of Parts

In cold heading, the metal fibers are not cut but instead flow and align according to the shape of the part. This results in improved mechanical properties for the finished product, significantly increasing tensile strength, shear strength, and fatigue resistance.

Stable Dimensions and High Precision

The mold controls the shape and size, ensuring consistent forming and reducing the need for further machining. This is beneficial for standardized and automated production.

Eco-friendly

The process operates at room temperature without heating or coolant, resulting in low energy consumption and minimal emissions, aligning with sustainable manufacturing principles.
