Low Pressure Diecasting | Gravity Diecasting | Sandcasting
We’re one of the few European companies to offer gravity diecasting, sandcasting, and low pressure diecasting in a single foundry. You benefit from synergies because we can combine elements of each diecasting process. For example, for complex components we can manufacture prototypes using sandcasting until the design is perfect, and can then complete the production run using gravity or low pressure diecasting.
Low Pressure Diecasting
With lower energy and post-casting finishing costs, as well as increased yield rates and cycle times, low pressure offers considerable commercial benefits. The process also provides exceptional casting integrity, thin wall sections and excellent surface finishes. As a result it can be the ideal solution for those looking for high quality and lower unit costs.
We are the most technically advanced low pressure diecaster in the UK, and our low pressure machinery is the biggest available in Europe. With the ability to manufacture a range of components using LM6, LM9, LM25 & A356 alloys, we’re the best in the business when it comes to developing ingenious, customer-specific solutions.
Our range of gravity diecasting machines includes semi-automated tilt and pour, semi and fully-automated hydraulic free standing and conventional mechanically-operated technologies.
We can produce gravity castings up to 1.5 x 1.2 metres. Shot weights range from 0.2 kilogrammes up to 45 kilogrammes, and we use six different aluminium alloy specifications. We manufacture a diverse range of castings including footplates, valve components, safety-critical suspension assemblies, housings and brackets.
Sandcasting is carried out using a mechanised carousel casting unit, which produces production quantities, small batches and prototypes. Through sandcasting we have the ability to produce prototype and sample castings, allowing you to assemble a new product for test evaluation prior to production quantities being produced or expensive gravity, low pressure or high pressure tooling being manufactured.
Our technical experts carry out state-of-the-art magma flow simulation, and we have the capability to take a ‘solid model’ CAD image – STEP, IGES or CATIA file. Working with you and your designers, we develop an analysis of the flow of the molten metal into the casting cavity, and this simulation determines the position of ‘metal in and out gates’ in the pattern.
Finishing and Assembly
Our fettling team is famous for its attention to detail and its consistency. Processes include shot blasting, linishing, grinding and polishing, with powder coating, wet painting, impregnation and plating carried out locally. Our finishing and assembly department also executes minor assembly work after components have been treated. As part of our extensive capital investment programme we are expanding the finishing and assembly machinery we have in house, further reducing unit costs and lead times.
