We Build The Best

Knapheide Iso Logo

Since its humble beginnings in 1848, The Knapheide Manufacturing Company has continually worked to improve its processes and manufacturing capabilities. Due to this commitment of continual improvement, Knapheide stands today with the most highly automated and technologically advanced equipment and processes in the industry. Knapheide's Westphalia facility houses the majority of our manufacturing processes. The Westphalia plant was completed in 1997 and covers a staggering 480,000 square feet.

A recent highlight in the continuing history of The Knapheide Manufacturing Company is the company receiving ISO 9001:2008 certification. ISO is a quality management system that is recognized globally. While the core of this certification is focused on product quality, Knapheide took the process a step further and utilized the processes to improve virtually every area of the company from how orders are received and processed to the shipping of the product to the end customer.


Our dedicated manufacturing employees are a huge asset to our company, and receive on-going training for continuous improvement. Knapheide delights in the fact that many of its employees are multi-generational and have a long tenure with the company. Knapheide’s training program for its welding operations is second to none. Six AWS certified CWI and CWEs conduct a forty hour program that all welders must complete prior to joining the assembly team. Of its team of welders, over 100 are AWS certified.

Assembly Process

After all of the engineering and fabrication of the prime unit parts is complete, the assembly process begins. Knapheide’s assembly procedures and multiple progressive lines allow them to be very flexible, highly efficient and produce the highest quality product in the industry. Knapheide has a large offering of catalog products that are quickly available and meet a large portion of our customers needs. However, while most of the industry shy’s away from custom built products, the Knapheide Company prides itself in its ability to build product that is designed to meet specific customer requirements and needs. Rather than limit the product available to their customers to standard product, Knapheide’s motto is “Dream it, and we will build it”. Some of the assembly processes include:

  • MIG & Resistance Welding
  • Automated Robotic MIG & Resistance Welding
  • Flexible Product Assembly Lines & Processes
