Our rigorous quality control standards are central to every operation, and are at the heart of why we are the undisputed leader in zinc and aluminium casting and finishing.
It is essential that zinc and aluminium castings have a low level of porosity – if they are too porous they can develop holes or buckle under loads.
Using the correct equipment is crucial to achieving the correct porosity, which is why we pride ourselves on our range of machinery. A large zinc casting may require a 400te press to minimise porosities and maintain quality across the run; putting the same tool on a smaller machine will result in a casting with an inferior surface, making it more difficult and more expensive to achieve a suitable finish. The latest casting machines accommodate the requirement for low porosity by enabling the stroke of the press to eliminate virtually all unnecessary air in the tool before the metal is injected.
We agree a porosity level with all our clients as part of our quality control regime, as the age and design of the tool being used can have a material influence on the level of porosity that is achievable.
Having the perfect chemical composition is essential to achieving a high quality casting. We use state-of-the-art technology to monitor the chemical balance on a continual basis, ensuring the integrity of the casting and the strongest possible bond between the surface and the coating when it comes to finishing. This also allows us to melt and reuse metallic waste without diluting the alloy, making casting more cost effective.
We are committed to minimising our environmental impact, and all our processes are geared towards eco-friendly manufacturing. Our production management techniques mean we are able to use machinery as efficiently as possible and reduce the amount of waste we produce. And best of all, this means we reduce costs as well as carbon footprint.
