H. E. Morse Co.公司 成立于1946年，此后不久，一种独特的电镀工艺被开发出来。朝鲜战争期间，H.E.摩尔斯公司开始为美国政府制造螺纹塞规Hemco Gage。独特的电镀工艺应用于量规的镀铬，使其比标准工具钢量规的使用寿命延长400%。Hemco的制造工厂位于美国密歇根州的荷兰。该组织现在通常被称为Hemco或Hemco量规，生产全系列的固定限位量规和可变量规，包括螺纹和圆柱形或平面。Hemco的Ekonogage是我们在荷兰生产的销规生产线。Hemco Gage还生产符合美国石油学会（API）规范的量规，是美国仅有的两家获得API标准量规生产许可的制造商之一。Hemco Gage的产品因其较长的使用寿命和卓越的质量而得到世界各地的认可。
