As we have since 1934, Rocklin Manufacturing (Sioux City, Iowa, USA) delivers the highest quality industrial electronic equipment for customers throughout the world. 

We manufacture the Rocklinizer Carbide Application Equipment, which enhances gripping and extends the life of metals, tools and dies.  The Model 950 accomplishes this faster and with heavier deposit capabilities than ever before.  We also manufacture the MoldMender Micro Welder, which repairs plastic injection molds and dies made of steel.    

We selectively import quality products for distribution throughout North America, including: Markator dot peen and scribe marking equipment featuring the FlyMarker® battery-operated marking units, the LaserEvo fiber laser marking units, and the Lase One Micro Welder. Additional information on our sales and distribution expertise can be found here.

All of our products are specifically designed to boost productivity and lower costs in support of our core mission to Give Manufacturers an Edge.



Since 1934, we have operated by core values that form the pillars of how we do business:

  1. The Platinum Rule: We treat customers, reps, and fellow employees how they want to be treated.

  2. Passion for Quality: Nothing leaves our doors without meeting the utmost quality standards.

  3. Extraordinary Support: We deliver unrivaled service rooted in open and honest communication.

  4. Problem Solving: We resolve our customers’ greatest challenges through innovation.
