Ocean Avenger Plus Drill Line
Macfab Engineering are currently arranging for the installation of an Ocean Avenger Plus Drill Line, which will enhance our ability to drill, thread, countersink, mill and do carbide scribing. The single spindle carbide drilling unit traverses the length of the material support table and automatically measures the placement of individual holes within a part program. Profiles placed along the edge of the material support table are automatically detected by the drill spindle via an innovative laser sensing device, and processed accordingly. The drill line has been described as a “horizontal CNC radial arm drill on steroids”.
National Supplier Prequalification
Macfab has qualified for RMS National Prequalification System for Civil (Road and Bridge) Construction Contracts Category S, and in 2014 this requalification was again extended for another 3 years.
Improved Galavanising process
Macfab Engineering in conjunction with our local galvanizers, have improved the way that our barrier rail sections are galvanized. During the galvanizing process the barrier rails are dipped into the molten zinc for coating, and then removed at a slow gradual rate, so as prevent zinc build up. Previously areas of high zinc build up has been ground back using an abrasive tool and then touched up by applying gal paint. After an analysis of the dipping process, we have been able to determine the optimum rate of removal from the zinc bath, and this has dramatically reduced the amount of touching up that is now required, leading to a superior product and a reduction of costs.
Even though we have easy access to city based galvanizers, we chose to use a local supplier, because we have not yet been able to find an alternative that can match their quality.
Macfab Engineering has improved the way that our twin rails are transported to site, so as to minimize damage and to improve the presentation of the product. We now use plastic strapping, instead of the conventional metal straps to lock rails together.
Macfab Engineering have also developed and manufactured a new plastic inter-locking packer, which is used to prevent the galvanizing finish being tarnished by rubbing.
Barrier rail installation bracket
Macfab Engineering have designed and constructed a holding bracket that can be easily retrofitted to forklifts that will assist in the fitting and handling of heavy bridge railings. The bracket, which also includes a tool tray, reduces the risk of poorly secured railings falling off or sliding on the forks while in transit, and enables the railing to be oriented into position while virtually eliminating manual handling. This innovation was nominated for the 2011 for the Work Cover – Work Safe Awards.
Macfab Engineering now employs 5 (all qualified engineers) project coordinators, who are assigned specifically to our customer’s projects. These people are charged with knowing everything about the projects they are assigned, liaising and keeping our customers updated and ensuring that the project is completed to the requirements of our customers.
Operate on Day and Afternoon shift
To optimize the use of our facilities and to minimize the production time of our fabrications, Macfab Engineering operates a day and afternoon shift, which means on each work day we are manufacturing for a minimum of 19.5 hours.
