Hi-Spec Precision Engineering utilises the following in house facilities to improve and enhance the finish on components and products we manufacture ~
Vibratory Finishing - "Rumbling" or "Vibratory Finishing" can be used to debur and remove sharp edges from machines components in large quantity. The rumbling process utilises specially shaped stones or pellets which rub against the components being treated by the vibratory action. This process can also be used to ball burnish and polish components to high grades of visual finish. The resultant surface finish produced during rumbling is a uniform mottled effect which evens out inconsistances in material appearance and provides a consistant base for subsequent anodising or plating processes. Vibratory finishing can also be used to clean, de-scale and remove rust and dirt from components prior to fabrication or repair work
Wet Spray - Our fully enclosed dry filter spray booth allows components, assemblies and fabrications to be professionally finished in colours to suit our customer requirements. Installed new in June 2011 the inlet air is filtered to ensure a quality finish and through the use of high intensity lighting consistant results are possible. The booth has internal dimensions of 2.2m x 4.4m to allow wet spray of multiple items or single large items
Hand Finishing - Careful hand finishing and deburring result in pleasing visual finishes on components that are unable to be processed by other finishing techniques due to size, shape or the item being too delicate. Abrasive finishing by either power tool or hand smooths out blend marks and material inconsistanies to give a more uniform surface. Orbital finishing of aluminium and steel components produces an enhanced consistant surface which can be further improved by anodising or plating
Abrasive Blasting - This process quickly removes scale, rust, paint and other finishes to allow easier repair work, fabrication or coating. A number of different medias are available to produce different grades of finish. Abrasive blasting produces a clean, consistant surface with the best surface adhesion for the subsequent paint finish
