Small Parts Pressure Testing & Autofrettage for Diesel Engines

Posted by & filed under News.

Harwood Engineering has supplied pressurizing equipment for autofrettage service since its inception in 1948. Generally, the requirement has been for the autofrettage of large steel forgings. Recently, however, we have developed a system for the pressure testing and autofrettage of small parts, such as diesel nozzles and manifolds for diesel engines.
