Need help creating a new design or solving a problem with your existing wire form? Our engineers, machine setup technicians, and tool makers review your wire form for functionality and manufacturability and look for improvements and cost savings. With over 75 years of custom wire form manufacturing experience, we solve the toughest challenges.
Contact us if you need samples quickly or to setup a discussion with a knowledgeable engineer to review and advise on your design.
Master Spring tailors wire form packaging to meet your unique assembly line and finished product needs. Our custom packaging solutions include tangle-free packing for efficient assembly operations, individually bagged and labeled parts ready to ship to your customers, and custom-built crates that securely transport large, heavy wire forms. Contact us today for more information about our wire form special packaging services.
Let Master Spring’s wire form assembly services lower your production costs by reducing the components you have to purchase and inventory. We can assemble your wire form with its mating part and send the sub-assembly to you.
Master Spring’s experience and quality process provide the documentation you require for your wire forms.
We have experience providing a Production Part Approval Process (PPAP) to our customers. After receiving our PPAP report, you can assess our process stability, review our controls to provide conforming product and have an approval outlet for any wire form design changes.
We create a First Article Inspection Report (FAIR) for each production run. The FAIR indicates the nominal dimensions, tolerances, precise measurements and methods of measurement for a requested quantity. Each FAIR provides a record of the raw material heat number to provide traceability to the batch of wire used for each production run.
Upon request, we can include certificates of compliance, material certificates and finishing certifications with each shipment of wire forms.
Strict vendor management and lot control enable us to comply with regulatory compliances including Conflict Minerals, DFARS, REACH, RoHS or California Prop 65. Let us know your documentation, certificate and compliance requirements when you request a quote.
WIRE DIAMETER RANGE
Our 3D-bending machines form a wide range of wire sizes. With full CNC control of all axes, our machines can manufacture complex, custom wire forms with wire diameters as small as 0.010” or as large as 0.394” (0.25mm to 10mm), and any size in between.
We have invested in a large inventory of universal tooling to cover the wire diameter range for each wire forming machine. If your wire form requires custom tooling, our in-house tooling design and machining capability supplies custom tools quickly and economically.
WIRE MATERIAL TYPES
Master Spring maintains strong relationships with local, qualified wire distributors and mills that offer quality wire to meet your specifications. We have years of experience making custom wire forms from many different material types:
Low-carbon Steel Wire Grades: 1006, 1008, 1010, 1018 and 1020
Medium-carbon Steel Wire Grades: 1135, 1038 and 1045
High-carbon Spring Steel Wire : Hard-drawn wire, music wire and oil-tempered
*We normally use a Bright Basic surface quality for the low- and medium-carbon steels. Some Carbon Wire Types can be pre-plated with a galvanized, zinc-coated finish, a tin-coated finish or Bezinal®-coated finish.
Properties of Materials Guide
Looking for information about common materials used in wire forms? Explore our guide to learn about nominal chemistry, minimum tensile strength, maximum operating temperatures, Rockwell hardness and suitable uses for each material.
To complete your wire form, we offer an extensive variety of finishing types. We manage a strong network of local, qualified vendors who offer quality finishes, short lead times and competitive pricing. Learn more about our finishing services below.
In-house Stress Relief
We use in-line ovens at each wire forming machine to apply low-temperature stress relief. This process alleviates residual stresses produced by prior cold forming and improves the wire form’s shape memory to maintain its formed shape.
For wire forms that require high-temperature hardening, such as austemper, harden and temper, vacuum heat treatment and ferritic nitrocarburize, we partner with local, qualified heat-treatment companies.
Shot peening improves resistance to fatigue, prevents cracking and increases lifecycle. The shot peening process blasts the surface of the wire with steel or glass pellets to create deformations. Our local, qualified vendors specialize in quality shot peening and surface preparation.
Tumbling improves surface finish by removing unwanted sharp edges and burrs from standard machine cuts.
Our large network of qualified platers provides a wide range of plating finishes such as black oxide, zinc, nickel, tin, trivalent chromate and many more finishes in a variety of colors.
Numerous powder coat colors are available for wire forms.
An acid treatment for stainless steel, passivation removes contaminants and improves corrosion resistance. We recommend passivating stainless steel wire forms used in the medical and food industries.
Electropolish brightens, removes burrs and passivates. For best results, use it on 300-series stainless steel types.
In-house Dye or Paint
Color coding helps identify and distinguish similar parts in your assembly line. We use an environmentally safe, water-based polymer coating. This coating adheres to the wire form in-line immediately after oven stress-relief.
E-coat is an electrically applied paint coating that is used as a decorative or protective finish. It enhances appearance while also protecting the surface of wire forms.
Magni coat is a thin, paintable coat that provides exceptional corrosion protection in extreme environments. It is superior to zinc-plating.
We can add a plastic coating to your wire forms in a variety of available colors.
Pre-applied Inert Threadlocking
This pre-applied process fuses a nylon threadlocking patch to the external threads of wire forms. Once applied, the threads are self-locking, self-sealing, dry to the touch and ready for immediate use.
