Through years of intensive development, Hengerda has accumulated the process technology system centered on metal materials and heat treatment. Applying the technologies, the company serialized products such as die-cutting tools, saw cutting tools, and other cutting tools. The technology and performances of our featured products are at the level of “Internationally Advanced.” Hengerda is the leading company in drafting industry standards of the heavy-duty die-cutting tool.

In 2011, Hengerda passed the “National High-Tech Enterprise” examination for the first time and passed re-examinations for consecutive years up to the present day. In 2018, Hengerda obtained ISO09001:2015 Quality Management Systems Certification and ISO014001:2015 Environmental Management Systems Certification. Hengerda independently developed an automated production line for die-cutting tools and saw cutting tools. This production line for heavy-duty die-cutting tools well exceeded the early limit of processing only a single 2-meter profile per batch. The line can produce rolls of die-cutting steel and band saw cutting tools without welding. It helped to form a continuous operation, stable quality, complete automatic production line. The bi-metal band saw blade production line can run automated production and control. The products are finished with superior mechanical properties: high toughness, good tensile fatigue resistance, high abrasive resistance, and impact resistance.
