Modern manufacturing emphasizes the protection of personnel and imposes higher requirements on the working environment. Kinmark has introduced the silent engraving equipment in response to these needs, effectively resolving the issue of marking noise in assembly and welding plants. This equipment has now fully replaced expensive imported units and is widely utilized by automotive manufacturers such as Volkswagen, Mercedes-Benz, Toyota, General Motors, and Hyundai. These marking machines can connect to the factory's MES network to automatically retrieve printing data and upload the results in real-time, demonstrating a high level of automation. At specific stations, the use of robotics can achieve fully unattended marking operations. We provide a complete workflow including positioning, marking, and discernment by integrating robotics, vision recognition, and other technologies to deliver turnkey services to our customers. We especially recommend the following four categories of equipment to effectively solve noise issues on-site, with operational noise levels below 70 decibels.
