Secondary Processes

Plating

Plating is used in a variety of applications such as solder ability, wear ability, and corrosion resistance. Common plating materials include gold, palladium, nickel, and tin. Metal strips can be processed to avoid preplated to avoid any secondary processing. Precious metals can be plated onto a strip and finished parts reels can be control-dipped to reduce the cost of plating. Precious metals can be bonded onto a strip as an inlay or cladding.

Heat Treating

Heat treating is used to add additional strength to metals after stamping. When the required form does not allow a product to be made without cracking, heat treating is often used. With heat treating, the part is stamped in soft form and then hardened. Heat treating is not a preferred process, however, since it costs additional and requires longer lead time. Heat treating could also result in variations in the final part. When a metal is formed in a soft state, it will relax during heat treating. Relaxation can result in variability of the formed part from material lot to material lot. To minimize the disadvantages of heat treating, we use a precisely calibrated over to determine how the tool must be compensated to account for the resulting relaxation.

Deburring

Although we meet most production requirements directly from the metal stamping die, to assure that parts are free of sharp corners, we provide both chemical and abrasive deburring.

Degreasing

Our degreasing process removes both organic and inorganic contaminants from treated pieces providing finished goods of impeccable quality. We are able to treat both metal and on-metal surfaces including those with complex shapes, blind holes, or hard-to-access cavities.

Insert Molding

CSI produces various parts that are integrated with an insert molding process. We work closely with our insert molding supplies to allow our customers to receive a high quality finished part.
