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 customers! In addition to ISO 9001:2008, we have an extensive internal quality control process highlighted by our use of Advanced Product Quality Planning (APQP) for all customers and products, regardless if the parts are being produced for automotive use.

The company's growth over the past 40 years is a testament to meeting 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.
