At UB Plastics, we help bring ideas to life with practical, production-ready product design services. Whether you’re starting from scratch or refining an existing concept, our in-house team supports every stage of the design process – with a clear focus on mouldability, performance and cost efficiency.
Why Choose UB Plastics for Product Design
We’ve built our reputation on practical experience, dependable service and long-term customer partnerships. With advanced mould tooling, automation and design support, we offer a complete moulding service – from concept to final delivery. Trusted by global brands and committed to sustainability, UB Plastics is a reliable partner for high-performance moulded parts.
Built on Experience
With roots going back to 1983, UB Plastics has decades of know-how in injection moulding. Trusted by major brands. We’re proud of our heritage, and even prouder of where it’s taken us.
Advanced Capability
We run 23 injection moulding machines, from 35T to 220T, with high-speed robotics and in-mould labelling. It means we can deliver consistent, high-volume production with precision – every time.
Committed to Sustainability
From recycled tamper-evident caps to efficient, low-waste production, we help our customers meet sustainability goals without compromising on quality.
End-to-End Support
We go beyond moulding – offering in-house design, tooling, stockholding and delivery, to make your project run smoothly from start to finish.
Trusted by Leading Brands
We’ve earned the confidence of major names in brewing, food, packaging and construction – by delivering quality, reliability and service that speaks for itself.
Design Expertise
We use a combination of industry-standard design and simulation tools to ensure your part is fully optimised for injection moulding. Over our 40+ years of business, we’ve helped hundreds of customers bring their designs to life, as well as develop our own range of products.
Our design capabilities include:
- SolidWorks – 3D part and assembly modelling
- AutoCAD – for dimensional detailing and legacy compatibility
- CADCAM software – for toolpath generation and CNC tooling workflows
- Moldflow analysis – to simulate flow, cooling and warpage before tooling investment
- DFM (Design for Manufacture) reviews – to reduce risk and improve tool performance
Our experienced in-house team works collaboratively with customers to create robust, production-ready designs that minimise waste and improve part quality.
Sectors we serve
While our roots are in the brewing industry, we now support a wide range of sectors including beverage, food packaging, construction, fenestration and general trade moulding. We work closely with customers in each market to ensure our moulded components meet technical, aesthetic and regulatory requirements.
Brewing
We supply millions of moulded parts for the brewing sector, including closures, keystones and shives. Built for function, made for efficiency.

Frequently Asked Questions
We’ve answered some common questions below about plastic part design, mould tooling, and how to ensure your product is suitable for injection moulding. If you’re planning a new part or adapting an existing one, these insights can help avoid delays and reduce long-term costs.
Injection moulded parts typically need uniform wall thickness, appropriate draft angles and no undercuts (unless side-actions are used). We assess your design early on to ensure it meets these requirements.
DFM is the process of adapting a product design to ensure it’s efficient and cost-effective to produce using injection moulding. It helps avoid tool modifications, defects and unnecessary costs later.
Yes. We offer design reviews, CAD modification and flow simulation to optimise parts for tooling, cooling, filling and ejection.
We typically work with STEP, IGES and native SolidWorks files. We can also review DXF, DWG and PDF drawings if needed.
Ideally at concept stage. Early involvement helps ensure your design is tool-ready and avoids rework due to moulding constraints.
Yes. We use Moldflow simulation software to model how the material will flow, fill, cool and shrink within the tool – helping reduce the risk of warping, short shots or sink marks.
We factor in polymer-specific shrinkage during product design, and verify dimensions using first-off inspections and regular in-process checks.
This depends on complexity, but most projects move from design to sampling in 4–12 weeks. We’ll advise timelines clearly at the start of the project.
Yes. Logos, part numbers and surface textures can be added to the tool so they appear directly in the moulded part. We’ll advise how to position and size these features for best results, or alternatively, can print or label your parts post-moulding with our printing and IML services.
We help you choose based on strength, flexibility, food contact compliance, temperature resistance, and cost. Common options include PP, HDPE, TPE and more specialised engineering polymers.
