Wireforms

We produce wireforms with a diameter of up to .250”. Our wireforms are either hard tooled on slide forming machines, or produced on CNC forming equipment. We regularly perform coining, chamfering, piercing, and threading operations on our wire form parts. We also insert various threaded fasteners. | Expansion plugs are commonly used to seal holes in castings and manifolds. Cup plugs have a tapered edge that once installed creates a positive seal and prevents leakage. They are simple to install and require only a machined hole. Welch plugs have a spherical radius and flatten out when installed creating a positive seal. They are more complex to install and require a machined counterbore. Ground edge welch plugs are available for applications that require exceptional pressure or leak resistance.
