表面光滑抗拉能力強不弯曲变形，弹簧经过表面强化处理提高应力集中点的強度。黄、蓝、红、绿、茶、黑等颜色区分负荷大小轻小负荷、轻负荷、中负荷、重负荷、极重负荷，更容易选择。
The surface of the spring is smooth and has strong tensile ability without bending deformation, and the strength of the stress concentration point is improved by surface strengthening treatment. Yellow, blue, red, green, tea, black and other colors distinguish the load size light small load, light load, medium load, heavy load, extremely heavy load, which is easier to choose.
日本模宝弹簧sup12材质抗疲劳、韧性好、耐腐蚀性及抗氧化能力超强不易生锈，正常使用寿命可达100万次以上。
The super-12 material of Japan mold treasure spring has good fatigue resistance, toughness, corrosion resistance and oxidation resistance, and is not easy to rust. Its normal service life can reach more than 1 million times.
日本模宝弹簧高频不易受损，最高使用频率可达3次/秒，更适合高频、高速振幅的高要求模具使用。
The high frequency of Japanese mould spring is not easy to be damaged, and the highest frequency can be up to 3 times / second, which is more suitable for the mould with high frequency and high-speed amplitude.
本产品出产前已经过強压处理，消除了使用前的内应力避免了弹簧发生变形、缩短、断裂等现象。
The product has been strong pressure treatment before production, eliminating the internal stress before use to avoid deformation, shortening, fracture and other phenomena of spring.
专为冲压模、五金塑胶模设计，在狭小空间能产生強大的动力。
Specially designed for stamping die, metal plastic die, it can produce powerful power in narrow space.
日本模宝弹簧郑重承诺，正常使用保证1年或100万次以上的使用寿命，并常年提供无偿的技术支持和非标件设计、定制方案，真正让您省力、省心、省钱！
Japan mubao spring solemnly promises to guarantee a normal service life of 1 year or more than 1 million times, and to provide free technical support and non-standard design and customization programs throughout the year, so as to truly save you labor, heart and money!
