Design and Engineering For EV Powertrain Cast Components & Body In White Structural Parts

> Your Enquiry

At Finecast, we use the latest CAD software to allow us to process raw component native data from SOLIDWORKS, CATIA V5 and Pro E files directly from the customer, alternatively we can produce EV casting models from 2D drawings if no 3D data is available.

We can also reverse engineer from existing components using our onsite 3D CMM laser scanning and Computer Tomography capabilities to create both casting and machining 3D data sets.

> 3D CAD Modelling & Mould Assembly Package

Our talented CAD team will work with your product model and casting requirements to create a complete 3D CAD dataset. The raw casting model will be optimised to incorporate machining and draft allowances before customer approval. The result is a 3D mould assembly package incorporating split lines and printed core locations.

> MAGMA Virtual Casting Simulation

Finecast utilises Magmasoft® 32 Core, the most advanced virtual casting simulation software within the foundry industry.

Our specialist virtual simulation engineers can now prototype properties prior to production, ensuring optimal 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.

Through virtual casting simulation we can reduce development lead times, optimise the final cast product design, identify areas for reducing weight from over-engineering and guarantee reliable mechanical data and accurate stress analysis for every EV cast component we manufacture.

> Additive Manufacturing 3D Sand Printing

We operate the most advanced 3D sand printing systems in the world from our in-house 3D sand printing centre, allowing us to produce complex castings within 24 hours from Magmasoft® simulation validation.

This technology provides flexibility to print in a wide array of thermally efficient sand media which enhances casting design, surface finish and casting tolerance.

We can quickly produce high-precision sand casting moulds and complex cores in volume, combine multiple traditional cores into one printed piece and allow for greater repeatability, improved accuracy and the ability to cast extremely complex shapes.

3D sand printing also provides substantial economic and environmental benefits by reducing the need for expensive, time-consuming conventional foundry tooling. This technology allows us to lower casting costs, significantly shorten lead times and reduce our carbon footprint due to the costly and unsustainable way polyurethane resin is recycled.

> Foundry Tooling / Pattern Making

At Finecast, we have a range of in-house foundry tooling facilities, which together with our team’s knowledge and experience, can machine-cut dimensionally-consistent pattern equipment and fixtures up to 2000 x 1000 x 420 mm in size.

As all of our work is done in-house, we guarantee confidentiality with our clients’ sensitive designs.

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.

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

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.

> Pressure & Leak Testing

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.
