풀필먼트 서비스는 이제 온라인 비즈니스 및 B2B 성장을 위한 필수 선택 요소입니다. 입고 와 재고관리, 주문처리 에서 배송까지 모든 과정을 전문적으로 관리해 보세요!!. greetings Greetings from the CEO We sincerely thank our customers who visited our company, Daehwa Reducer Co., Ltd. We are a small and medium-sized enterprise specializing in the production of reducers and precision gears. Since our establishment, we have grown steadily and have gained an advantage in technology and production capacity in the same industry. We are growing into a global company by focusing on manufacturing highly reliable gear products through continuous development and facility investment in the production of gear products that are essential to various industrial facilities. Also, based on the CEO's management philosophy of 'patriotism through localization', we are introducing the world's leading precision gear processing machines and developing new technologies to localize various gear products that had previously been dependent on imports. We are producing reduction, medium-speed, high-speed gears and gearboxes used in ships such as LNG ships, passenger ships, and special-purpose ships, as well as power generation, using our own technology, thereby achieving a huge import substitution effect. Thanks to the support of our customers, we have been able to produce more precise products. We will devote all our efforts to the development and production of more precise products and promise to do our best to supply excellent products based on the principles of sincerity, trust, and speed. With the expansion and relocation of the factory in 2006, we have laid the foundation for producing products with greater precision and speed. We will reward our customers with the highest quality products. I would like to ask for your further guidance and advice. CEO Choi Hae-seok COMPANY About Us
