Fastening & Forming

Orbital Forming

Orbital forming is a cold forming process using a peen tool held at a fixed angle to create a sweeping line of pressure around the part, progressively forming the material with each rotation. This process reduces the amount of forming force required by approximately 80% of a standard press.

Radial Forming

The radial forming and riveting process is similar to the orbital riveting and forming process. But with radial, the material is displaced from the center outward in a rosette or floret pattern. The radial riveting process is often the optimal assembly solution when working with small rivet shank diameters, delicate rivet materials, or unsupported rivet assembly applications.

Impact Riveting

Impact riveting is an assembly process that uses force to permanently fasten two surfaces together. There are a variety of rivet and material possibilities, including solid or semi-tubular rivets. The advantage of impact riveting is the cycle time is fast and the assembly operation is simple.

Hot Upset Forming

The hot upset forming and riveting process uses heat and pressure to form the fastener. The material being formed becomes malleable and collapses under pressure applied by the powerhead. Using this process, it is possible to form a round fastener into a square hole, creating very high torque joints. This process is excellent for forming parts that will incur high vibrational fatigue.

Static Roller Forming

Roller forming is a non-impact process using a spinning roller head, with two or more rollers, to apply a symmetrical downward force to form a part. Static roller forming is often used to form an aesthetically pleasing lip around a cylindrical part. The non-impact nature combined with precision and accuracy makes it possible to form delicate and brittle materials. Static roller heads provide consistency and efficiency to your forming process.

Articulating Roller Forming

Articulating roller forming is used when forming a groove in a part or when there are obstructions to clear in order to form a lip. The articulating roller heads come in from the side to create the formed area. The 360-degree contact means consistent action for the entire time the part is being formed. These roller heads can deliver forming forces up to 5,000 lbs at 100 psi.

Press Riveting

Press riveting is an assembly process that uses a hydro-pneumatic press head to apply a downward force to form the material. Press riveting is typically used with 1” diameter rivets or larger.
