Reverse Engineering in HFS provides customers :
▶ Complete service from maintenance to the supply of all necessary spare parts
▶ The minimization of our customer’s warehouse stock
▶ Reduction of general maintenance cost
▶ Improved and upgrade for better performance
Reverse engineering has the objective of making any changes to the construction materials of the components considered to be damaged early or abnormally in order to improve the mechanical characteristics and increase overall reliability, with benefit on safety as well as economic.
Additional goal is to reduce manufacturing cost of the new product making it competitive in the market. When facing deadlines, demanding outage schedules, or an emergency breakdown, HFS provides expert services that is designed to minimize downtime and maximize customer
In most cases, spare parts supplied by the customers are not compatible because they are obsolete, in other cases they are out of the production or the procurement times cannot be reconciled with the planning of maintenance and operations. Reverse engineering is the process of extracting knowledge or design information by using 3D scanning data capturing system and redesign a used/new part of valve maker such as stem, trim, packing and so on.
By undergoing reverse engineering, parts are not only be duplicated from the original but also improved and upgraded for better performance. The construction and precision of the build components is guaranteed attributed to the use of CNC multi-axis machining and turning centers, where the information extracted from the reverse engineering activity and the 3D modelling of the components to be built are perfectly integrated with production CAD/CAM system.

CNC machine, Lathe machine, Milling machine, Drill machine and welding machine are contributed to manufacturing the valve internal parts. After manufacture, the dimensional check and NDE test are carried out to ensure the quality and standards of finished product are met. Before packing, the leak test and pre functional tests are carry out if necessary.
