· Providing solutions for our customers, taking products from the concept phase through mass production.
· Capability to conduct all fastener manufacturing processes in-house, under one roof.
· Built-in quality control-by-process.
· Extensive in-house testing capabilities.
A wide range of bolts, nuts, and screws, of a broad range of sizes, are formed in this process. In this first step of fastener manufacturing, steel coil is cut to a specified length, and achieves the required shape through two or more blows in the cold forming process.
Rolling or Tapping
IAF possesses capability to apply a broad range of thread diameters to both male-threaded fasteners (using plate or rotary dies) and female-threaded fasteners (using tapping bits). When washers or additional components are required, automated assembly also occurs in this process.
Quenching and tempering lines provide the specified mechanical properties in higher-strength fasteners. Separately, IAF utilizes continuous bluing and annealing lines to ensure the mechanical properties in the fasteners for which these processes are specified.
IAF possesses extensive in-house surface treatment capabilities, depending on the corrosion-resistance requirement of the fastener. Zinc electroplating with hex chrome-free chromate is standard for a wide range of fasteners used in the interior of a vehicle. IAF also utilizes in-line baking to prevent hydrogen embrittlement. For fasteners requiring a higher level of corrosion resistance, IAF applies dip-spin processes such as Geomet® and Magni Coat®.
Plastic Injection Molding
IAF provides many unique product solutions, some of which utilize metal fasteners with plastic inserts. The Plastic Injection Molding area conducts this process on a number of high-volume fasteners.
