Rocklin Manufacturing Co.

Rocklin Manufacturing Co. is a long-established U.S.-based company that specializes in the design and production of industrial equipment aimed at extending tool life, reducing downtime, and improving productivity across a variety of manufacturing sectors. Founded in 1934 and headquartered in Sioux City, Iowa, Rocklin has built a strong reputation for offering niche, highly specialized solutions to challenges faced in machining, metalworking, and related industries.

One of the company’s flagship product lines is the Rocklinizer®, a patented electro-spark deposition technology. This system applies hard, wear-resistant coatings of materials such as tungsten carbide and titanium carbide to metal surfaces. The process significantly enhances the durability and performance of tools, dies, and other wear parts, without altering their dimensional integrity. It is widely used in stamping, forming, tube bending, die casting, and other heavy-use applications where surface wear and premature tool failure can drive up costs.

Another key innovation from Rocklin Manufacturing is the MoldMender® Micro Welder, which allows manufacturers to repair damaged or worn molds quickly and cost-effectively. By enabling in-house repairs, the MoldMender reduces downtime and eliminates the need for costly outsourcing. Main uses for the MoldMender is small imperfections such as scratches, nicks, design changes and parting line flash.

Rocklin Manufacturing also distributes dot peen and laser marking equipment and laser cleaning machines.
