AAK液压阀使用40Cr做阀套材质,顺利补救意大利客户液压市场

与90%的液压阀厂家不同,AAK液压阀阀套使用40Cr材质,不会出现卡顿现象,及时挽救了客户David在意大利的液压阀市场,而我司也逐渐成为他的主力供应商。

阀套材质的选择,直接关系液压阀的各种表现。国产1214钢材易切削、产量高,同时对加工刀片的损耗比较小,目前绝大多数同行为了节省成本,使用国产1214钢材做阀套,往往忽略其存在的潜在问题,脆性、热处理容易变形等,阀套若出现变形、则会导致弹簧底座在旋紧、旋松过程中,出现卡顿、失灵现象,从而影响压力、流量的调控,目前绝大多数的厂家生产出来的产品都存在这些隐患。

意大利的David这两年主要负责中国华东地区的液压阀采购市场,去年其在我们液压同行采购的一批先导式的液压阀,从生产到组装没有任何问题,甚至最后经过试压台的检测也是过关的,此订单市场销售数据也很乐观。David团队正计划再下一个返单、且数量翻倍,然而此时却收到30%的客户投诉,问题都如出一辙:弹簧底座卡顿、调节两到三次就出现松弛现象,压力、流量的调控几乎失灵。

他无意中在网上看到我们公司的网站,简单邮件沟通后,我们建议他来公司实地比较。第二天David带着样品来到我们公司,这些产品从外观根本看不出任何问题,于是我们立即对样品进行更精密的参数检测,经过旋紧、旋松反复2-3次循环等其他测试,就出现卡顿、调节失灵现象,查看了一下测试参数,原来问题是出在阀套内螺纹上,存在轻微变形、几μm的误差,肉眼是看不出来的,才导致与弹簧底座的配合运作过程中出现卡顿现象。David很惊讶我们这样快的速度查出病症,问我们怎样做能够避免这些隐患。

我们将我们的阀套材料数据和他的样品材料数据一一对比给他看,他就明白了其中的奥妙了。为了避免再次出现品质问题而丢了意大利的市场,他希望赶做一批订单给他去替换目前出问题的产品。随着这几年品质的稳定,David团队得到新老客户的认可,我司也逐渐成为他 的主导供应商。

AAK生产的液压阀阀套都是使用40Cr,主要是40Cr经合适温度热处理后,在韧性、塑性和耐磨性上,达到上佳的综合力学性能;尤其对钢材高频淬火及回火等表面硬化处理,AAK有自己的专有技术。

对AAK液压阀你还有顾虑,也很正常,但不要错过我们,可以小试一单。
