Flexible Duct Connectors
Ruichi focuses on the R&D, production, and sales of HVAC ventilation products, with 20 years of production experience and 11 years of online service expertise. As a core connecting component in ventilation systems, flexible connectors link ventilation ducts and equipment. Leveraging their retractable and deflectable properties, they absorb vibrations from equipment operation, compensate for duct installation deviations, ensure smooth air flow, and offer dual functions of shock absorption, noise reduction, and pipeline system protection. Crafted with high-quality galvanized steel and stainless steel as base materials, combined with high-performance materials such as silica gel, glass fiber, and PVC, the products balance durability and adaptability. The standard specification is 75*140*75mm with a thickness of 0.4-0.6mm, available in three colors (gray, red, green) to precisely meet the needs of ventilation ducts under different temperature conditions. Customization services for size, material, and shape are also provided upon request. Since 2012, Ruichi has been supplying the U.S. market and participating in professional AHR Expos in Las Vegas, Chicago, and other cities. With stable quality and professional services, it has gained deep trust from customers worldwide.

Knowledge
China metal stamping parts are widely used in the sheet metal processing process. In the process of material deformation, we need to rely on a variety of metal stamping molds to limit the shape of the product, including laser cutting, CNC punching, bending, deep pull, embossing, etc. The metal stamping manufacturing process of turning a metal plate into a solid shape. Metal stamping processing is an efficient solution for mass production, providing high-quality stamping processing parts for industries like aerospace, automotive manufacturing, medical equipment, electronics, industrial, and building.e packing options include plastic bags, bubble packs, kraft paper, nylon bags, and small cartons. For outside packing, carton and pallet options are available. With carton packaging, they can print logos, do color printing, or use customer – provided box drawings; they can also design packaging drawings and customize carton sizes. Pallet packaging options cover plastic, wooden, metal pallets, and wooden cases, with designs tailored to product size and weight to prevent breakage. Other custom packaging requests are also welcome.
China metal stamping is a cold-forming manufacturing process. Stamping equipment uses instant stamping deformation or cutting metal plate through stamping mold to produce customized metal stamping parts. Metal stamping technology has been widely used to different parts and a variety of stamping processes, but they all need rigid stamping mold and pressure cooperation, to complete the blanking, bending, stamping, embossing, and other manufacturing processes.
