The company always adheres to technology as the driving force, precision manufacturing as the core, and quality control from the casting source. It has an independent casting base, strictly implements real-time monitoring of material composition and physical performance analysis, and relies on full process testing methods such as chemical composition analysis, tensile testing, and metallographic charts to ensure the consistency and stability of casting quality. Adopt high-end processing equipment and intelligent production lines to achieve one-stop molding, and ensures product precision through a full-process quality control system supported by precision testing instruments. Introduce high-end processing centers from Japan, Taiwan and other places in the manufacturing process, build intelligent unit production lines, and achieve one-time molding from clamping to finished products. The quality system runs through the entire manufacturing process, controlled layer by layer through "first inspection, patrol inspection, and final inspection", and equipped with precision instruments such as coordinate measuring machines, cylindricity meters, projectors, and cleanliness analyzers to deeply verify the shape and position tolerances and surface quality of parts, ensuring that product accuracy meets design requirements. .templete-con82 * { margin: 0px; padding: 0px; -moz-box-sizing: border-box; box-sizing: border-box; } .templete-con82{position: relative;width: 100%;} .templete-con82 .con-tbody{position: relative;width: 100%;} .templete-con82 .con-tbody .con-tbody-list{position: relative;font-size: 0;letter-spacing: 0;display: flex;flex-wrap: wrap;margin-left: -20px;margin-right: -20px;} .templete-con82 .con-tbody .con-tbody-items{position: relative;display: inline-block;vertical-align: top;width: 33.3333333%;padding: 0 20px;margin-bottom: 36px;} .templete-con82 .con-tbody-items .items-box{position: relative;width: 100%;height: 100%;overflow: hidden;} .templete-con82 .con-tbody-items .items-box .items-pic{position: relative;width: 100%;text-align: center;overflow: hidden;border-radius: 10px;} .templete-con82 .con-tbody-items .items-box .items-pic img{display: inline-block;vertical-align: top;width: 100%;} .templete-con82 .con-tbody-items .items-box .items-body{position: relative;width: 100%;padding: 8px;text-align: center;} .templete-con82 .con-tbody-items .items-body .items-title{position: relative;width: 100%;font-size: 18px;color: #333;font-weight: bold;line-height: 30px;} @media screen and (max-width:1459px) { .templete-con82 .con-tbody .con-tbody-list{margin-left: -12px;margin-right: -12px;} .templete-con82 .con-tbody .con-tbody-items{width: 33.3333333%;padding: 0 12px;margin-bottom: 30px;} .templete-con82 .con-tbody-items .items-box .items-body{padding: 7px;} .templete-con82 .con-tbody-items .items-body .items-title{font-size: 18px;line-height: 30px;} } @media screen and (max-width:1259px) { .templete-con82 .con-tbody .con-tbody-list{margin-left: -6px;margin-right: -6px;} .templete-con82 .con-tbody .con-tbody-items{width: 33.3333333%;padding: 0 6px;margin-bottom: 24px;} .templete-con82 .con-tbody-items .items-box .items-body{padding: 6px;} .templete-con82 .con-tbody-items .items-body .items-title{font-size: 16px;line-height: 28px;} } @media screen and (max-width:991px) { .templete-con82 .con-tbody .con-tbody-list{margin-left: -20px;margin-right: -20px;} .templete-con82 .con-tbody .con-tbody-items{width: 50%;padding: 0 20px;margin-bottom: 24px;} .templete-con82 .con-tbody-items .items-box .items-body{padding: 5px;} .templete-con82 .con-tbody-items .items-body .items-title{font-size: 16px;line-height: 28px;} } @media screen and (max-width:720px) { .templete-con82 .con-tbody .con-tbody-list{margin-left: -12px;margin-right: -12px;} .templete-con82 .con-tbody .con-tbody-items{width: 50%;padding: 0 12px;margin-bottom: 20px;} .templete-con82 .con-tbody-items .items-box .items-body{padding: 5px;} .templete-con82 .con-tbody-items .items-body .items-title{font-size: 16px;line-height: 26px;} } @media screen and (max-width:560px) { .templete-con82 .con-tbody .con-tbody-list{margin-left: -5px;margin-right: -5px;} .templete-con82 .con-tbody .con-tbody-items{width: 50%;padding: 0 5px;margin-bottom: 20px;} .templete-con82 .con-tbody-items .items-box .items-body{padding: 4px;} .templete-con82 .con-tbody-items .items-body .items-title{font-size: 16px;line-height: 26px;} } Establish a dust-free constant temperature assembly workshop with specialized test benches to ensure zero-defect, high-performance hydraulic components through 100% national standard testing, while building a globally oriented R&D team to provide talent support for development.
