In-House Custom Thermoforming SolutionsPackage Design: Dordan engineers its thermoform packaging in Siemens NX. The package developmental process is very structured and transparent, with fundamental collaboration between the customer's requirements and capabilities of thermoforming.
Thermoform Tooling: All prototype and production tooling is programmed, machined, and built on site, including ancillary components. The same team of packaging engineers who develop the design also program the CNC tool paths, allowing for the seamless transition from concept to manufactured part.
Thermoforming: 14 thermoforming machines that have the capacity to convert over 100MM pounds of materially annually, including two Kiefel thermoforming machines in our ISO Class 8 cleanroom. Dordan has 63 years of custom thermoforming experience, converting a wide range of materials for diverse industries and applications.
ISO Class 8 Cleanroom: For manufacturing packaging for sterile applications that require production in a controlled environment.
ISO 9001:2015 & ISO 13485:2016: Certified quality management system maintains our commitment to the on time delivery of defect free thermoformed products and packaging.

A fully enclosed and complete hardwall constructed space, Dordan's cleanroom works to maintain the cleanliness of the environment with a cascading airflow design, terminal cleaning, dry fogging, and more. Ideal for medical devices that require the packaging be manufactured in a controlled production environment, Dordan's cleanroom produces consistently high quality medical packaging that meets the standards of its ISO certifications.
Dordan’s ISO 9001:2015 and ISO 13485:2016 certifications govern every step of the thermoforming process, including:
Incoming material inspection and traceability
First article inspection, first article validation, full process validation (IQ/OQ/PQ), PPAPs
Automated in-process inspection with real-time CPK analysis
Extensive documentation for regulatory compliance

Dordan History
Founded in 1962 by Edwin and Vivian Slavin, Dordan began as a small skin vacuum forming company in Chicago.
Under second-generation leadership, Dordan transitioned to CAM/CNC thermoforming in the mid 1970s, investing in new technologies and modernizing its equipment, software, and quality systems.
In the 1990s, Dordan relocated to Woodstock, IL to expand production. In 2013, Dordan achieved ISO 9001:2008 certification, which was updated to ISO 9001:2015 in 2017.
In 2018, we built our ISO Class 8 cleanroom. In 2024 we achieved ISO 13485 certification for medical packaging design, manufacture, and distribution.
Today, four generations of the Slavin family work at Dordan, a testament to the company's culture and values.
