Guttenberg Industries, Inc. (GII) has provided custom plastic injection molding and related services to customers throughout the world since 1974.

About_Us_OwnersWe are a privately-owned second-generation family business with more than 130 employees. We operate three shifts on a 24/5 basis (24-hours, 5-days a week) with occasional Saturday shift(s) depending upon demand.

Between 2012 and 2020 our revenues have grown by more than 100%!  This is a testament to our employees’ ability to meet the needs of our most demanding customers. We have built and maintained many long-term customer relationships through an extensive focus on efficiency and product quality and performance.

The strength of Guttenberg Industries resides in our employees. They provide the expertise to produce the quality products and maintain the personal relationships with our customers. This expertise results in a high quality product, better inventory management, and savings in time and money for our customers.

We are recognized for our diverse range of custom injection molding capabilities. This means producing very small plastic injection molded pieces to larger parts and from a wide variety of materials. Our 80,000 sq. ft. manufacturing facility now has 33 plastic injection molding presses, ranging from 55 to 950 tons. We utilize robotics on virtually every machine, from simple sprue pickers to full-servo robots. This allows the additional flexibility to minimize manufacturing costs and become a less expensive alternative as a single source provider.

In November 2015, we relocated our corporate offices to Garnavillo, Iowa where our plant had been located since 1995.  This new 8,000 sf. facility reunited the company into one location and has proven to increase our internal efficiency.

Our 80,000 sq.ft. of manufacturing space also includes an additional 8,000 sq.ft. to our production/warehouse in 2016 and a tornado shelter added in 2018.

Beyond manufacturing custom plastic injection molded parts, we also provide extensive value-added services.

This allows for a faster production-to-finish-to-delivery schedule while also reducing transportation costs between vendors. Among the advanced services we provide are ultrasonic and spin welding, thermal and ultrasonic insertion, over-molding, chrome plating, hot-stamping and pad-printing, as well as in-mold labeling (IML). In addition, we also specialize in effective and efficient press-side and post-production assembly, including packaging.

Quality assurance and industry certifications are essential components with Guttenberg Industries’ custom injection molding processes. In fact, our quality standards and processes are often more stringent than those required by our customers! In addition to ISO 9001:2015, we have an extensive internal quality control process highlighted by our use of Advanced Product Quality Planning (APQP).
