Linear vibratory continuous finishing system (Thailand Design)

High throughput capacity, high profitability, and unlimited automation possibilities are the main characteristic of HMTSS1500 vibratory continuous finishing system.

It is widely used in high volume production for surface finishing, deburring, radiusing in stamping, forging, die-casting processes. Inovatec HMTSS1500 system provides extraordinary reliability in processing.



Recently with the increasing cost of the manual polishing process and high requirement of automation, continuous linear vibratory finishing machine is gaining preference for industries for large production volume especially medium to large size work parts.

The machine and process developed by Inovatec offer a good choice for finishing a solution of a high-quality standards. The result is repeatable and the process is customized according to customer requirement. So far, the continuous linear vibratory finishing system is one of the most popular mass finishing machinery around the world.

Working principal

The work part is continuously fed into linear processing chamber with certain cycle time, together with ceramic media or plastic surface finishing media. The sidewalls of the processing chamber can either U shaped or straight according to customer requirements. The vibratory force generates by high-frequency motor rotate the mass along the chamber wall. Meanwhile, work parts are moving forward together with mass media.

The processing parameter includes processing chamber angle setting, balance weight for motor, motor frequency as well as time control.

After the work parts went through the whole processing chamber, media and parts can be separated in a nylon sieve unit. In the meantime, parts can be cleaned and with spray water and possible post-treatment, for instance, vibratory drying machine or chain belt drying machine.

After all, media after separation with parts is returned to the processing chamber for recycling.


The linear continuous finishing machine suitable for casting components from medium to large size, especially for components with continuous production and delicate high valued product. For example, alumina alloy dies casting parts, magnesium alloy dies casting parts, steel engine housing as well as other structural components. The processing includes deburring, surface grinding, edge rounding, polishing as well as ball burnishing.

Productivity is high compared with manual processes and easy to achieve automation.


The superior equipment concept of the Inovatec linear continuous vibratory finishing systems is based on the fact that all processing is made in control. The complete processing is designed based on specific requirements. The vibratory motor, the separate unit with customized design as well as PLC control station make sure the long-lasting life of machine and repeatability of the process.
