Types of Wire Forming

From manual to CNC, roll-forming, and beyond, a variety of wire forming techniques are used in the production process, each suited for different types of materials and projects.

We'll look at some methods widely employed in industrial manufacturing processes around the world.

Manual Wire Forming

Manual wire forming is a traditional method of bending and shaping metal wires into useful parts such as springs, fasteners, retaining rings, and others.

This process can be done through simple hand techniques. The manual wire form process begins by selecting the right steel alloy type or quality for specific applications and climates.

Then, it must be cut into specific lengths depending on what parts need to be produced. After cutting comes bending, which can involve twisting, looping, or even manipulating small pieces of material so that they fit together snugly when connected at any desired angle.

Coil Wire Forming

Coil wire forming uses machinery to transform metal wire into coils or spirals. The process begins with either spooled metal wire or cut-to-length blanks.

The flexibility of metals allows for the creating of diverse shapes like bends, spirals, curves, and custom chains from a single piece of material.

Beyond creating coils and spirals, this process includes additional features like drilling holes, creating notches, forming loops, connecting links, threading, attaching parts, and applying various finishes.

Fourslide Wire Forming

Fourslide wire forming uses four slides to create intricate parts efficiently. It involves die-stamping multiple small metal components simultaneously, offering advantages for complex projects.

The process utilizes a punch press with multiple slides and custom tools to bend and shape components, providing greater design flexibility without sacrificing productivity.

CNC Wire Forming

CNC wire forming uses advanced programming and automation to create precise parts efficiently, making it suitable for high-volume production.

CNC wire forming machines are used in various industries to craft well-defined forms while reducing raw material waste and cutting costs. It can also be an effective tool for creating simple shapes to complex two-dimensional configurations without compromising accuracy or durability.

Roll Wire Forming

Roll wire forming shapes wires into various configurations using a series of rolls or dies. It includes a range of techniques like bending, swaging, piercing, chamfering, and shearing to create precise and complex features for metal components.

Roll wire forming is favored by many because it has greater accuracy compared to other types of metal forming processes due to its capacity for making tight radii bends that can’t be achieved with manual methods like press brakes or water jets.

Roll wire forming also produces smooth curves, requiring minimal polishing, if any.

Bending Wire Forming

Bending wire forming is introducing an angle into otherwise straight wires. This helps to modify or create parts, shape components, and structurally reinforce projects across various industries.

The process can be done manually but most often utilizes machine stamping for efficiency. In wire forming machinery, the bending head is where all the shaping action takes place.

Depending on the project's scale, it may include a combination of rollers and press tools that apply precise forces along angles to produce the desired output.

Hydraulic Wire Forming

Hydraulic wire forming is a method of shaping and manipulating wire and metal parts using a hydraulic press, which applies pressure to the material being manipulated.

This process allows for complex wire forms such as clips, pins, springs, and more intricate structures to be created with repeatable accuracy.

The process involves applying force onto the metal to shape it into its desired form, including bending or swaging. A servo motor fitted with CNC programming software controls the tooling required in this setup.

Pneumatic Wire Forming

Pneumatic wire forming refers to the process of shaping or bending wires using pneumatic (air-powered) systems.

Pneumatic bending is ideal for producing more complex pieces due to its ability to deliver smooth arcs without buckling - something much harder with manual techniques.

Depending on their size or purpose, pieces can range from simple artisan design components and handles to highly sophisticated industrial items suited for automotive and engineering applications.
