At the end of last year, a batch of core components, including screws and barrels, ordered by a European customer was successfully delivered to the customer’s facility and gradually put into production use. After several months of operation, the customer expressed strong satisfaction with the performance and stability of the products and decided to place an additional order for screw and barrel spare parts. This repeat order not only reflects the customer’s trust in COWIN product quality but also further demonstrates COWIN’s manufacturing capability and long-term product reliability in extrusion equipment components.
With 10+ years of continuous development, COWIN has established a mature and rigorous quality management system. From the quotation stage, the technical and production teams carefully evaluate each project according to the customer’s processing requirements, ensuring both technical feasibility and competitive solutions for different extrusion applications.
For specialized projects, the engineering department is responsible for detailed drawing design after contract confirmation. All drawings are internally reviewed before being submitted to the customer for final verification. Both parties maintain complete technical documentation and drawing archives for future production, maintenance, and spare parts management. COWIN continues to focus on providing long-term, stable, and sustainable service support for customers worldwide.
During manufacturing, strict control and traceability are maintained throughout the entire production process, including raw material selection, heat treatment, machining, and assembly procedures. Every production step is fully documented to ensure stable and reliable product quality. After manufacturing is completed, all components undergo comprehensive inspection by experienced technicians, and any parts that fail to meet quality requirements are rejected before shipment.
Even for outsourced supporting components, COWIN works only with reliable and established suppliers within the industry, and all incoming parts are re-inspected before entering production. This long-term commitment to detail and quality control forms the foundation of COWIN’s high-quality extrusion components.
Customer recognition and continued cooperation remain the strongest affirmation of COWIN’s quality management and manufacturing capabilities. Looking ahead, COWIN will continue to uphold its commitment to stable quality, long-term service, and the Win-Win Together philosophy, creating greater value for customers around the world.
