The Complete Design & Manufacturing Hub For Creating,
Complex, Lightweight, High-integrity EV Castings
We design, engineer and manufacture complex, lightweight, performance-enhancing sand cast components, including electric drive units, battery housings and large structural body in white (BiW) parts.
We are committed to supporting our customers at each stage of the manufacturing journey, with a ‘make-like-production’ approach to rapid prototyping and supporting initial production phase builds through to scheduled production volumes up to 5000 units.
At Finecast, we provide a complete one-stop solution for manufacturing high-integrity, fully machined sand cast components in a wide range of materials. Working with the latest technology from our state-of-the-art facility, our in-house advanced processes include CAD, virtual MAGMASOFT® 32 CORE casting simulation, 3D sand printing, foundry tooling, low/medium-volume series foundry, heat treatment, metallurgical testing, non-destructive testing, 5-axis CNC machining and CMM dimensional validation.
Our state-of-the-art facility, technologically advanced processes combined with our team of highly skilled and experienced engineers, give us the ability to deliver high-quality, fully finished cast components exactly to your specifications, meeting tight lead times and the highest industry quality standards.
Finecast is dedicated to helping support the continuing developments in the electric vehicle industry and contribute towards a greener, cleaner future.
Precision Sand Casting For EV Powertrain Components & Structural Body In White Parts
> Rapid Prototype Castings
We have a purpose-built prototype facility that allows us to rapidly manufacture complex, high-precision EV cast components to ensure proof of concept, integrity and validation before beginning large-scale production.
Our team of experienced engineers can achieve this by utilising our ‘Magmasoft® 32 Core’ virtual simulation software, accredited materials lab, 3D sand printing centre, robotically controlled foundry, cast validation lab (X-Ray/CT Scanning/GOM/Creaform) and dimensional validation lab (CMM).
This advanced approach to rapid prototyping allows us to produce EV cast components of the highest quality in just a few weeks, helping our customers significantly reduce the time it takes to develop electric vehicles.
> Lightweight Engineering
As leaders in our industry, we are helping to power the electric vehicle market by pioneering the development and manufacture of strong, lightweight, highly durable aluminium body in white structural parts.
We are continuing to push the boundaries by producing large body in white structural parts up to 3m2 with a consistent minimum wall thicknesses of 2.5mm, a linear cast tolerance DCTG7 and a superfine surface finish of 4RA.
Through careful material research and innovation, we have developed lightweight body in white structural parts by using refined high silicon aluminium alloy series and low-volume sand cast production to effectively replicate the mechanical and geometric properties achieved with high-pressure die castings.
> Low/Medium Volume Series Sand Casting Foundry
At Finecast, we can support both initial production phase builds through to scheduled production volumes up to 5000 units, providing flexible solutions to our clients.
We understand the importance of high-precision, high-integrity and quality finished castings, especially when it comes to EV’s, and can produce a wide range of EV cast components including, electric drive units, battery enclosures and large structural body in white parts in-house thanks to our low/medium volume series foundry.
As innovations in this area thrive, we continue to commit investment and resources into securing the most advanced robotic foundry equipment. From automated mixing to high-speed mould filling and closing stations, we can save our customers time and money using repeatable processing suitable for components of up to 2m2.
We are now able to reclaim up to 95% of the sand we use with our new state-of-the-art thermal sand reclamation system. This allows us to make our sand casting process more efficient and significantly lower our carbon footprint.
We can also optimise the sand quality during the thermal reclamation process, which results in exceptionally high-quality castings with superior surface finishes.
Cast Product Validation For EV Powertrain Components & Body In White Structural Parts
> Chemical, Composition & Mechanical Analysis
Our teams use in-house specialist laser spectrographic equipment to provide a detailed chemical, composition and mechanical analysis for all types of sand media and casting material.
We aim to fulfil clients’ engineering specifications by carrying out regular spectrographic analyses of the melt sample throughout the production process. This analysis is performed by our own MA-qualified metallurgists, ensuring effective quality control at every stage.
As a result of our detailed analysis and testing, we’re able to produce EV sand castings that are high-integrity, free from defects and meet all of our customer’s requirements.
Our specialist team of MA-qualified metallurgists have a wealth of experience in this field, who continue to innovate and develop unique alloys designed for lightweighting while improving strength, ductility and durability for thin-walled castings.
> 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 carry out heat treatment using a range of water and polymer quench to control over-distortion and residual stresses for all castings in accordance with our customer’s requirements.
> Geometric Optical Measurement
We specialise in high-precision geometric optic measurement, which helps ensure consistent, accurate components that are built according to your unique specifications.
Our team uses optical scanners (GOM/Creaform) to carry out our advanced inspection and validation processes. These state-of-the-art tools help us guarantee dimensional accuracy and stability, using a generated 3D model that can be superimposed onto the parent EV part CAD model.
The process allows for strategic alignment between the casting and machining datums, ensuring we deliver highly accurate machined casting exactly to our customer’s requirements.
We strive to maintain impeccable standards at Finecast and deliver EV components with the highest integrity and free from defects. Utilising our in-house GE Seifert X|Cube 320KV CT Scanning System, we can identify microporosity, small incipient cracks and surface imperfections for each and every cast component we manufacture.
We perform rigorous pressure and leak testing to guarantee the integrity of our EV sand castings. Checks are carried out using air decay or hydrostatic pressure testing. This process helps us verify castings by repeating various leak rates and test pressures.
CNC Machining For EV Powertrain & Structural Body In White Castings
> Fine-Machine, Close Tolerance Complex Components
Our state-of-the-art machining division is equipped with the latest high-spec Mazak CNC machining centres and driven turning machine tools enabling us to offer a fully integrated service.
At Finecast, we have not only invested in the highest quality machine tooling technology, we also have a talented, experienced team of engineers specialising in CNC machining complex geometry and close tolerance components in a variety of material grades.
This enables us to guarantee repeatable, high-quality finished machined EV cast components.
Dimensional Validation For EV Powertrain & Structural Body In White Machined Cast Parts
> Machined Component Dimensional Validation
Our in-house metrology laboratory enables us to carry out detailed inspections and validations for each and every casting project. Our validation technology includes 3 CMMs, including two equipped with fully programmable probe stations to measure machined EV cast components up to 2 m.
We are also able to provide quick and accurate surface finish, contour and angle measurements using our Hobson Taylor Talysurf.
Thanks to our investment in the latest technology, combined with the experience and knowledge of our inspection team, we can carry out detailed validation that meets our customer requirements including CPK Indices, SPC analysis, full ISIR and FAIR reports.
