Recently, a well-known machinery manufacturing company entrusted Openex Metal Fabrication (hereinafter referred to as "Openex") with the production and fabrication of a batch of key components for new environmental machinery equipment. This cooperation was built upon the success of a previous sample project, where the client was highly satisfied with Openex’s fabrication techniques and service quality. As a result, the company decided to hand over these key components for production.
These components are crucial to the core part of the environmental machinery equipment, demanding strict standards for manufacturing precision and consistent quality. The batch consists of more than 20 sets of parts, made from hot-rolled stainless steel with varying thicknesses from 1mm to 12mm. The specifications are complex and diverse, with stringent requirements for flatness and vertical cutting precision. This posed a significant challenge to the processing company’s equipment performance, technical capabilities, and management efficiency.
This project’s fabrication involved multiple stages, including flattening, cutting, bending, riveting, tapping, machining, assembly, and welding. Each step required high standards of technical support and precise coordination of equipment. To ensure the quality of the final product, our technical team developed a thorough processing plan, fully leveraging our advanced production equipment and efficient management practices.
The components for this batch of environmental machinery were made from hot-rolled stainless steel, with thicknesses ranging from 1mm to 12mm. To ensure smooth subsequent processing, our team classified the materials according to the process design requirements. Each part was precisely cut and categorized, with every sheet clearly marked with the customer’s drawing number and the next fabrication step, ensuring seamless handover between stages.
This phase heavily relied on our advanced flattening equipment—the FIMI 878 flattening machine. With its high precision and efficiency, this machine played a crucial role in controlling the flatness of the materials. By using precise flattening techniques, the surfaces of all plates were smooth and even, laying a solid foundation for the next cutting process.
Cutting is a key step in the entire manufacturing process. The precision of the cut not only affects the dimensional control of the parts but also directly influences the quality of the subsequent assembly and welding. We employed the German TRUMPF laser cutting machine, renowned in the industry for its high precision and stability, making it particularly suitable for cutting stainless steel.
The laser cutting machine melts the material at high temperatures to achieve smooth edges and high vertical precision. In this project, the customer required extremely high verticality in the cuts, and the TRUMPF laser cutting machine performed flawlessly in this regard. The edges of each part were smooth and burr-free, with verticality deviations controlled within micrometer levels, providing high-standard materials for subsequent bending and machining processes.
After the sheet metal was cut, it proceeded to the bending and machining stages. Bending requires the parts to be shaped without deforming or cracking. For stainless steel, due to its higher hardness, precise mechanical design and careful control are required during bending. We used advanced CNC bending equipment, where pre-programmed instructions ensured that every angle and bend radius was accurate, preventing material stress concentration and deformation.
The machining phase mainly involved flange manufacturing and local machining of certain components, such as milling surfaces, drilling, and tapping. This stage demands extremely high machining precision and consistency to ensure that each part fits perfectly in the subsequent assembly process. With an experienced technical team and efficient CNC machine tools, Openex ensured that every part met the required accuracy and stability.
The final steps involved assembly and welding. The components for environmental machinery are typically large and involve the integration of multiple parts, making the quality of the welding process critical. We used high-precision automatic welding equipment, complemented by skilled welders, ensuring the strength and smoothness of the welds while avoiding common welding defects such as porosity and cracks.
After welding, Openex conducted thorough quality inspections on all components, including dimensional checks, non-destructive testing of welds, and surface treatment inspections. Every stage was executed in strict accordance with the client’s technical specifications, ensuring that all finished products met or exceeded the expected standards.
The successful completion of this environmental machinery component processing project was largely due to Openex’s efficient management approach and strong team collaboration. From the start of the project to the final delivery, our project management team maintained close communication with the client, ensuring that every stage was aligned with the client’s needs and requirements.
To improve production efficiency, we implemented a one-stop fabrication service model. This means that the client could have every step, from design, material procurement, fabrication, assembly, inspection, and transportation, completed within Openex’s facilities. This model not only significantly shortened the project timeline but also reduced the client’s management costs, enhancing overall project efficiency.
