Tailored Injection Moulded Parts, Built Around Your Product
At UB Plastics, we support companies across multiple sectors with custom injection moulded components designed for their specific product, process or system. Whether you’re developing a brand-new part or adapting an existing design, we offer a complete in-house service, from design and prototyping through to tooling, moulding and delivery.
With over 40 years of experience, we’re trusted by brands across manufacturing, packaging, construction and beyond to deliver consistent, high-quality moulded components at scale.
Supporting Product Development Across Industries
Every business has unique needs, and off-the-shelf components don’t always fit the bill. Our custom moulding service is built for companies that require a specific size, function, finish or fit that standard parts can’t deliver.
We work with OEMs, technical buyers, design engineers and project managers to help turn concepts into repeatable, manufacturable mouldings. Whether you need hundreds or millions of units, we tailor our service to meet your priorities, from compliance and function to presentation and cost.
What We Can Produce
Custom mouldings vary in function, complexity and application, but all are built on the same foundations: robust design, accurate tooling and repeatable production. Common types of bespoke parts we produce include:
- Inserts, plugs, end caps or brackets tailored to fit a specific product or system
- Functional parts used in assembly, packaging, transport or final use
- Branded or decorative parts with colour or printed features
- Sealing or protective components for use in mechanical or packaged products
We can work from a detailed drawing or collaborate at the design stage to help develop your ideal component.
