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 145 employees. We operate three shifts on a 24/5 basis (24-hours, 5-days a week) with occasional Saturday shift(s) depending upon demand.

Founded by John Ertl in the river-community of Guttenberg, Iowa in 1974, the company really hasn’t stopped growing.

In 1995, with its’ facility full and no land left to expand upon, Guttenberg Industries added a manufacturing facility in the new industrial park developed in Garnavillo, Iowa – less than 10 miles North. For 10 years, two manufacturing operations were producing plastic parts. The decision was made in 2005 to expand the Garnavillo plant and move all production to the new facility. The corporate offices, including accounting, engineering, human resources, sales, and supply chain remained in Guttenberg.

As business continued to grow, and with a need for better time management, the decision was made to move the offices to Garnavillo. In November 2015, the new 8,000 sq. ft. office facility reunited the company into one location and has proven to increase our internal efficiencies.

The growth has continued. Between 2012 and 2020 our revenues have grown by more than 100%! Then, last year (2021) saw a 50% increase from 2019! This is a testament to our employees’ abilities 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 with part quality and performance. Again, our employees provide the expertise to produce the quality products and maintain the personal relationships with our customers. This results in higher quality parts, 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 80,500 sq. ft. manufacturing facility – plus an additional 24,000 sq. ft. for warehousing and shipping added in October 2022 – now has 37 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.

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).
