Stage 1

Design and Engineering For Powertrain & Body In White Components

> Your Enquiry

At Finecast our CAD resources allow us to use raw component native data in CATIA, Pro E and SOLIDWORKS files directly from the customer. Alternatively, we can generate the 3D casting and machined casting models from 2D drawings.

We can provide reverse engineering from existing components by using our CMM laser scanner and computer tomography capabilities to produce casting and machining 3D datasets. 

> 3D CAD Modelling & Mould Assembly Package

Our team of highly experienced CAD technicians can generate a complete 3D CAD dataset directly from your model of the machined casting and casting requirements. Feasibility analysis then leads to an optimised raw model incorporating machining and draft allowances. A 3D mould assembly package is then generated defining split lines and printed core locations.

> Virtual Casting Simulation

Finecast utilises Magmasoft 32 Core, the industry leading virtual casting simulation software which enables us to prototype properties before casting production takes place, removing the need for lengthy foundry trials and giving us the ability to ensure the method is qualified right-first time.

Through virtual casting simulation we can ensure optimal process conditions for mould filling, solidification and cooling, identification of casting defects and prediction of residual stresses through the cast component in both the as-cast and heat-treated condition.

Our specialist simulation engineers can optimise the final cast product design, identify areas for weight reduction from over-engineering, reduce development lead times and provide guaranteed reliable mechanical data and accurate stress analysis for every casting we manufacture. 

> Additive Manufacturing 3D Tool-less Sand Printing

Finecast now operates the most advanced 3D sand printers in the world from our new state-of-the-art in-house 3D printing centre, giving us the ability to produce complex castings within 24 hours of final Magmasoft virtual simulation validation.

By utilising the latest 3D printing technology we now have the flexibility to print in a wide range of thermally efficient sand media, allowing us to optimise casting design, surface finish and casting tolerance.

3D sand printing enables us to rapidly produce sand casting moulds and complex cores in volume, and to combine multiple traditional cores into one printed piece, allowing for greater repeatability, improved accuracy, and the casting of extremely complex shapes.

This new technology allows us to reduce casting costs, shorten lead times and become more environmentally friendly by significantly reducing the need for conventional foundry tooling.

> Foundry Tooling

Our in-house foundry tooling facility and specialist automotive engineering expertise allow us to machine cut dimensionally consistent pattern equipment and fixtures for a wide range of automotive applications. As we operate fully in-house we can ensure total confidentiality with sensitive automotive designs.

Stage 2                                                                                                                                                                         

Precision Sand Casting For Powertrain & Body In White Components

    > Rapid Prototype Castings

    Our purpose-built prototype facility offers the flexibility to rapidly manufacture and qualify superior quality, technically challenging cast products to provide proof of concept, integrity testing and validation before committing to large production volumes.

    We achieve this by utilising ‘Magmasoft® 32 Core’ the industry-leading Virtual Simulation Software, our in-house Materials Lab, 3D Sand Printing Centre, Advanced Low/medium Series Foundry, Cast Validation Lab (CT Scanning/GOM/Creaform) and Dimensional Validation Lab (CMM) combined with our extensive automotive engineering experience.

    Our unique rapid prototyping process can produce high quality automotive components within weeks, enabling our customers to considerably shorten product development time.

    > Lightweight Engineering

    Finecast is pioneering the development and manufacture of lightweight high-strength aluminium structural components for the automotive industry.

    We are now pushing the boundaries by producing large sized, highly-strong, highly-ductile and durable structural body in white (BiW) automotive parts with consistent wall thicknesses of down to 2.5mm and up to 2 metres in length.

    From extensive material research and innovation in lightweight powertrain and body structures we have developed and refined high silicon aluminium alloy series prototype and low volume sand cast production that replicates the geometry and mechanical properties of series in high pressure die castings.

    > Low/Medium Volume Series Sand Casting Foundry

    Our in-house foundry allows us the flexibility to support initial production phase builds up to scheduled mass production volumes up to 5000 units.

    We support low/medium volume production of automotive components where high cast and mechanical integrity and surface finish quality is critical, the vast majority of the castings we produce are for the motorsport, sports-car, luxury and electric vehicle markets.

    Our continued investment into advanced robotic foundry equipment includes automated mixers, high-speed mould filling and closing stations that offer efficient repeatable processing for components up to 2 msq.

    We have also invested in the latest thermal sand reclamation system allowing us to reclaim up to 95% of the sand we use in our foundry, making our sand casting manufacturing process more efficient and significantly lowering our carbon footprint.

    In addition, we can also optimise our sand quality during the thermal reclamation process, resulting in exceptionally high-quality castings with superfine surface finishes.

    Testing & Validation For Powertrain & Body In White Castings

    > Chemical, Composition & Mechanical Analysis

    From our in-house laboratory we use our specialist laser spectrographic equipment to ensure full traceability of process parameters to validate the chemical, composition and mechanical analysis for all types of sand media and casting material.

    Our team of MA-qualified metallurgists will perform spectrographic analysis of the melt sample throughout production to ensure chemical composition is meeting the customers exact engineering specification.

    This comprehensive approach to spectrographic analysis means we consistently produce repeatable, defect free, high integrity automotive castings every time.

    We have a wealth of experience in this field which allows us to develop unique alloy compositions designed for lightweighting, ductility, durability and thin-walled parts.

    > Heat Treatment

    From our onsite heat-treatment facility we can treat large castings to improve mechanical and physical properties, our largest solution furnace volume is 11.56m³ (2.15m x 2.15m x 2.5m). We use a range of water and polymer quench to control distortion and residual stresses in all components and in accordance with customer requirements.

    > Geometric Optical Measurement

    Our advanced inspection and validation process using optical scanners (GOM/Creaform) guarantees dimensional accuracy and stability by creating a 3D model which is superimposed onto the parent automotive part CAD model.

    The process allows for strategic alignment between the casting and machining datums, ensuring we deliver consistently accurate machined castings exactly to the customers specifications.

    > NDT – 2D Radio Tomography & 3D Computer Tomography

    It is critical for automotive parts to be high-integrity and defect free. Our powerful GE Seifert X|Cube 320KV CT Scanning System allows us to offer the very best non-destructive testing (NDT) in the UK and efficiently identify micro porosity, small incipient cracks and surface imperfection in all types of automotive components whether it be an engine block or a structural BiW part.

    > Pressure & Leak Testing

    The integrity of our automotive castings are checked and verified by using air decay or hydrostatic pressure testing. We are able to verify core complex components with intricate oil galleries such as engine blocks and cylinder heads by repeating various leak rates and test pressures.

    Stage 4
