Our Processes

presbar-diecastings-robotic-casting-cellPresbar began using fully automatic diecasting cells back in the 1980’s. This investment in our facilities led to the introduction of our first robotic cell (Photographed on the right) in the early 1990’s. We have continued to develop our foundry, and use cells that offer a very repeatable process to produce ‘capable’ diecastings that are very low in labour content. This offers cost savings to Presbar which we pass on to our customers.


induction-furnaceWe use Raydyne bulk melting facilities to produce our aluminium alloys. The use of these induction melting furnaces results in very homogeneous material that is better for subsequent machining. We further safeguard the quality of our material by the use of ‘in-house’ spectrometers to monitor the chemical analysis of every batch we produce.

The ‘In-house’ facilities at Presbar include shot blasting, vibratory deburring, linishing and assembly work. We have invested in large scale finishing plant, and automated processes wherever possible. This reduces the cost per casting to a minimum allowing Presbar to remain competitive in today’s market place.    In addition to the comprehensive in-house facilities, we also use our prefered outside suppliers to allow us to deliver painted, chrome plated or anodised parts.

Tool room facilities

Our skilled tool makers work in a well equiped tool room. The primary aim of this tool room is process development engineering – meaning that all improvements to the die, all modifications and maintenance can be carried out in-house by our own experienced team.

presbar-diecastings-chiron-cnc-machineIn addition to the more usual drilling and tapping operations, we also use the latest high speed CNC machining centres and Lathes from Chiron, DMG and Matsuura. We installed our fist CNC machining centers in 1986 and are experienced in machining to very high tolerances whilst maintaining high productivity. Our expertise gives our customers the cost benefit of having only one supplier producing fully finished components.  As well as purchasing single CNC machines, we have invested in complete cells of dedicated machining centres for our customers. If you have an application that would require such investment, we will enter into long term agreements and partnerships with you and make sure the capital was available.
