flat cylindrical helical spring

This red mold spring is made of high-quality 65Mn alloy steel. It has been quenched and tempered to achieve uniform hardness and durable elasticity. It is a common medium-load rectangular flat wire compression spring for both Japanese and national standards, widely adapted to injection molding, stamping molds, metalworking frame, and various industrial machinery equipment. It is used in scenarios such as resetting, cushioning, and shock absorption. The spring surface is coated with red paint, which is rust-resistant and wear-resistant, can withstand high temperatures, and is less likely to deform or break over long-term use. The service life exceeds that of ordinary springs. We offer a full range of specifications and support non-standard customizations to meet the precise installation needs of different molds and equipment.
