About Trans
Ningbo Trans Envirotech Co., Ltd is a leading one-stop solution provider specializing in the design and manufacturing of advanced industrial automation equipment for both dry and wet filtration applications. Driven by innovation and precision engineering, we are committed to delivering efficient, reliable, and highly customized automation solutions to clients worldwide.
With over 15 years of industry experience, the company has built a strong reputation in both domestic and international markets, particularly in terms of equipment stability, production efficiency, and continuous technological innovation. Our manufacturing system is supported by two core production bases with clearly defined specializations:
Nanjing Production Base – Dedicated to the manufacturing of automatic filter bag production equipment, including advanced sewing systems and complete automated production lines
Yongkang Production Base – Focused on the development and manufacturing of customized automatic welding equipment, designed to meet diverse industrial applications and non-standard requirements
This dual-base structure enables us to combine high-efficiency standardized production with flexible high-end customization, allowing us to effectively meet a wide range of customer needs.
Building on this foundation, the company is currently planning and establishing a third production base in Ningbo, which will focus on the development and manufacturing of high-end and special customized automation equipment. This new facility will be dedicated to complex processes, non-standard automation, and full-line integration projects, further strengthening our capabilities in handling technically demanding applications.
Beyond equipment manufacturing, we position ourselves as a comprehensive provider of one-stop solutions, covering automatic sewing systems, automatic welding systems, and complete process integration with technical support. By combining advanced machinery with optimized production processes, we help our clients achieve true automation, significantly reduce labor costs, and enhance productivity and long-term operational stability.
From standardized equipment to high-end customized production lines, Ningbo Trans Envirotech is becoming one of the few companies in the industry capable of delivering full-chain automation solutions.
Looking ahead, we will continue to be driven by technology and guided by customer needs, empowering global clients to build more efficient, intelligent, and competitive manufacturing systems.
