Custom design

Bespoke / Custom / OEM products

Tranquil PC since 2003 are specialists of "in house design, manufacture and supply" for bespoke IT platforms. Often these products have benefited from fan less operation, enabling them to provide long service life even in hostile environments.

Not everyone has the same technical requirements for their IT based solutions. So why should you be constrained to buy and use standard or slightly modified hardware platforms? Your product no doubt is unique because of the applications/services running on it - but by housing it in a 'known' case, even if that case is specially branded for you, may be exposing your organisation to (commercial) problems that you don't need.  

Sometimes the hardware needed to run your application within a specific environment just may not exist.

This is where Tranquil PC can engage and work with you to design and supply a bespoke product to your exact requirements.

The video belows shows our operations from CNC milling, anodising and laser printing which is then assembled to the final unit and passed for testing and validation, ensuring it will be functional in its intended environment.

​The Journey

Design Specification - here we take as much time as needed to work with you to fully understand your requirements to ensure that we have a full picture of what is needed. System schematics and work flows are a great tool that we use and share with you during this critical stage to make sure there are as few issues as possible in the follow on stages.

Design consultation and feedback - in addition to your requirements, we will often make a number of recommendations based on our experience and expertise. You are not alone in your 'journey' and working together will always result in a better solution.

Engineering - our mission is to work with you to realise your concept through to a completed product. You can rely on our expertise to bring the hardware aspect of your product to its conclusion.  

CAD - once we have an agreed product outline we will start on the product design itself. We use state of the art CAD systems to create every part of the final product. Editing the product design is normal, sometimes it may just not 'look right' - and our CAD systems allow fast and effective re-modelling.

CFD Simulation - if the first CAD model fails for some reason and it doesn't meet the environmental specification, we use advanced CFD tools to run the CAD model along with its real world materials, through a number of simulations - ensuring that it will meet the desired specification. If for any reason the design needs to be changed, it's back to the CAD stage.

Photo Realistic Rendering - so now we have a 3D CAD model that meets your needs and the CFD tests have confirmed it will function as required - but what will it look like? By utilising product rendering software it is possible to show you how your product will look, with different material textures, colours, labels etc. This can be very helpful to support your marketing department - if they want it in a different colour, or texture etc - then a new picture can be generated often within a few hours.

Electronics - should your product need specialised electronics for peripherals / input / output / power etc. then we may be able to help design those parts with you. Our team have decades of experience in electronics design and supply.

So far - so good...

Up to this stage your journey has brought you to a point where you can be confident that your new product is achievable, will work as you need, and will look amazing! But so far there is nothing 'real' to touch / test!

CAM - once you are ready to release your new product to first off manufacture, the 3D model is processed in our CAM systems. It is here where the product starts to become real. CAM is a process that generates hundreds or thousands of lines of machine code, known as Gcode. This code is then used by our CNC milling machines to control the cutting tools to 'carve' the product or components from solid billets of aluminium. But cutting the aluminium itself can be an expensive, time consuming and difficult process. We have advanced CAM software that ensures that the cutting tool paths are optimised to remove as much material as possible, as quickly as possible, with as little tool wear/damage as possible - this high MRR is achieved by advanced tool paths - known as iMachining.

3D Printing - on occasions it is necessary to quickly create small 3D models of components that are needed to be included in your final product. These could be printed circuit assemblies, connectors, windows, small fabricated parts etc. When these are needed they are manufactured on our 3D printer - often just to verify the 'placement / fit' of the component in the final product.

First off - all of the above processes have enabled the manufacture of the first off sample. As Tranquil have our own precision milling machines, we can quickly manufacture the first off

Finishing - more often than not, the surface of the aluminium parts need to be optimally anodised to ensure that the surfaces meet the models used in the CFD process. Our aim is to create a very effective 'black body' surface - ie a surface that is a very efficient 'heat radiator'. Tranquil has it's own anodising facility, and we do not rely on any external service companies, for the finishing / anodising of the products.

Final product assembly / test - once the product components have all been completed the final item can be assembled and tested to ensure it meets your specifications. If there are any non-conformance discovered at this stage, then revised components can be quickly manufactured and the product re-tested until it meets the specification.

Sign off - the product is now finished - it meets the specification - it looks just like the earlier rendered images - and you are able to sign it off.

Mass manufacture - as we have detailed information of the product it is a small step to move the design to mass production. The CAM stage ensured that the products can be manufactured as efficiently as possible. Tranquil has numerous high speed / high precision milling machines - to provide high capacity volume production. Our in house anodising facility is scaled to provide first offs but also to absorb the volume of units created by the milling machines, which can be 1000's of parts per month.  

Product assembly - Tranquil assemblies the final products in house - including cable preparation, chassis assembly etc

Product testing - all products are tested to a standard process, that is agreed with you - to ensure that when the product is finally packed and delivered it meets your exacting specification, ensuring first time working deliveries.

Additional Process

Custom BIOS - sometimes you may need a custom BIOS to be developed and loaded to the product. This is taken care of in the product testing stage.

Imaging - most products are built and shipped with customer o/s and applications pre-installed. The product image and imaging process it managed, again, in the product testing stage.

Burn test compliance - all products undergo a form of burn testing. These extended tests are designed to ensure the product does not develop 'early' field faults by load testing all components, prior to final release. The burn test criteria vary and depend on your requirements.

Custom setup - although all of the manufacturing / testing processes are all controlled and are consistent, on occasion a product, or series of products requires 'custom' setup - perhaps this is the deployment of a specific routing table for a switch. We can accommodate 'custom' builds.

Branding - Most products are branded for you, or for your customer. In most instances this 'branding' comes in the form of a laser process, which etches the logo / product markings from the anodised aluminium surfaces. This process is very efficient and the results both permanent and precise. On occasions products can be screen printed or labels applied.

Certification - where you need compliance certification we can take care of this on your behalf, as needed.

Life cycle - in the IT sector components have a tendency to have fairly short life cycles. Where possible we only recommend the design / supply of 'embedded' of ELC parts - to reduce the number of new iterations of the product. Life cycle management is controlled and pending EOL information is carefully communicated with you - and new versions of products developed in good time

The total experience - your absolute satisfaction

It's very important to us that you (our partner) are entirely satisfied and confident in the products and services that we provide - thereby allowing you to fully focus on what you do best and not having to worry about your (hardware) product development / manufacture / life cycle / fulfilment etc .  

By keeping all of the fragmented manufacturing stages under one roof, not only are we able to monitor the entire manufacturing process, but we can quickly introduce product improvement and change, or quickly ramp up output as needed.

Very importantly product development lead time is short, by industry standards, as the routes between all of the stages is minimal. All development step are processed within Tranquil.

This also applies to short product lead times and optimal product costs. Most stages of the process transition from one stage to the next, under one roof - with very little reliance on external service companies. This drastically improves efficiency - and the benefits are passed onto you
