Projects


Cast-iron CAD has worked on a wide variety of projects for a diverse range of clients. We are extremely adaptable and our team of design engineers can find a solution to almost any kind of challenge. Find out more about some of our previous projects below.

Educational toy - Numbuko™

Numbuko represents a revolution in the way that children learn about numbers. Instead of using books or screen-based activities, Numbuko™ uses magnetic, luminous, color-changing blocks to engage with your child’s natural curiosity and sense of play.


Intercom and access control

Aluminium and stainless housing designed to incorporate the clients existing 4G electronics into a robust, access intercom, designed for high-end applications. Complete MRP system engineered to ensure that stock is always available to accommodate predicted sales demand.

Teardrop trailer 

A new type of sports trailer. 

Based around the caravan, this new concept is lighter, cheaper and more adaptable, making it ideal for storing sporting equipment. The trailer is small enough to fit in a garage for winter storage when not in use. This exciting project is still in development.



Carpark access

The carpark access control pillar offers robust security with GSM-based remote access management. Ideal for residential or commercial car parks, it features easy setup, durable construction, and programmable access via mobile app, enhancing convenience and control for secure vehicle entry.

FEA Evaluation

Medical printer prototype

Functional prototype of an automatic medical vial and slip printing machine, simply insert a preloaded cartridge of either the vials or slips and the device prints QR codes directly onto the oriented item. For use in medical laboratories.

Office furniture

This coworking meeting table, inspired by a flower bulb, is crafted from steam-formed plywood. Its unique design offers both aesthetic appeal and functional workspace, encouraging collaboration in a visually engaging environment. The table’s organic shape fosters a creative and inclusive atmosphere for meetings and team activities.

Pill splitter

The TabTime Metal Pill Cutter offers a precise and easy solution for splitting tablets. Engineered with durable metal, this compact tool ensures a clean cut every time, enhancing medication management with its reliability and efficiency. Ideal for those needing accurate dosages.

Medication Tipper

Created for an automatic rotary pill dispenser, aimed at aiding individuals with conditions like dementia in remembering to take their medication, the tipper resets to its original position after dispensing the pills.


Phone housing - quick dial GSM

Artifact submersion tank

This artifact submersion tank was developed for the Mary Rose Trust, a UK organisation responsible for conserving and displaying the Mary Rose, a Tudor ship that sank in 1545.

(Image shows the what the tank preserved)

3D facility scan

Carried out for a major explosion protection engineering company based in the UK, our client required a full 3D scan of a refinery in Lithuania. Covering over 500,000m2, the refinery was scanned using a Leica Scan Station and then imported to an AutoCAD drawing. Our drafting team detailed a plan view, side views & created sectional views in AutoCAD based on the 3D image

Engineering drawings

We always meet BS8888:2013, ensuring a smooth transition between the design concept and manufacturing phases. Our parametric 3D design capability helps us improve product development times, resulting in your product being delivered to market quicker.

Pressure vessel

This project was created for the food and beverage sector with the need for adaptability to cater to various capacities and operational pressures. A novel sealing mechanism was integrated and subsequently endorsed by 3A, an independent organization setting sanitary standards for the food, beverage, and pharmaceutical industries.


Water Recycling


Designed for water separation from waste collected from road highway sweepers, water collected using this water segregation tipper is then treated and reused to clean more highways, aggregate is then be tipped and recycled.

Airborne wind turbine


Gearing system

A project to develop a new type of gearing system to replace an existing mechanism, this innovative system incorporated a variety of cam mechanisms to achieve the required motion, representing a significant improvement over their previous system, transitioning from a jarring to a smooth gliding motion.

Concept sketches

Toy train tr​ack


Elliptical trainer

By performing FEA assessment on unstable supports, a proposed solution was determined to reinforce the overall structure. As a result, the failure rate of this component was reduced, leading to increased customer satisfaction.
