Turning Concepts into Rotomoulded Products
Turning Concepts into Rotomoulded Products
Industrial Innovation
Services
Specialised support for rotomoulded product design and engineering, helping you turn ideas into real-world manufacturing solutions.
New Product Development
From concept to production, developing manufacturable products with CAD, refinement, and production support
Product Conversion for Rotomoulding
Convert existing parts or products for rotomoulding, optimising unit cost and design for assembly
Design & Manufacturing Support
Improve manufacturability, reduce costs, and refine designs, supporting tooling, suppliers, and production.
I’m Andrew Caldwell, a Chartered Mechanical Engineer with 20+ years’ experience delivering innovative, user-focused products. I’ve worked across consumer products, sanitation systems, and humanitarian-focused development taking ideas from concept through to real-world use and patented solutions.
In recent years, I’ve specialised in rotomoulded products, working closely with manufacturers internationally to turn concepts into production-ready solutions.
I’m a hands-on engineer who thrives on refining designs, solving problems early, and making sure products actually work - from initial CAD models to units deployed at scale.
About
Process
Taking products from concept through to production, combining hands-on engineering with practical problem solving. The process ensures ideas are manufacturable, user-focused, and delivered at scale.
Problem definition – understand the challenge and user needs
Concept generation – explore multiple solutions rapidly
Design development – optimise for manufacture and assembly
Detail design – final CAD models and documentation
Design
Produce
Factory selection – identify and assess the manufacturing partners
Tooling – oversee moulds, jigs, and production-ready tools
Sample reviews – test prototypes, validate fit and function
Production – support first runs and refine processes as needed
Manage
Cost modelling – ensure projects are financially viable
Project plans – milestones, schedules, and delivery tracking
Risk assessment – mitigate technical and manufacturing challenges
Supplier liaison – coordinate with international manufacturers
