Design Support
Turning a concept into a production-ready component requires more than good ideas. It requires experience, material knowledge and an understanding of how parts are actually moulded. At Rediweld Moulding, our design support service helps engineers and product development teams develop reliable, cost-effective plastic components that perform in real-world applications.
Our plastic product design service has extensive injection moulding expertise, we support customers from earliest stages concept generation, design development, prototype testing, through to final design sign off, managing production tooling, initial batch testing and ultimately full scale production.
Plastic Product Design & Development
Our team provides practical, hands-on support throughout the plastic product design and development process. We focus on creating components that are functional, manufacturable and commercially viable by being economic and resilient for a long service life.
Every design decision is made with tooling, materials and long-term performance considered from the outset.
- Concept generation for customers to consider different options for their product to go.
- Product design for injection moulded plastic part for applicaions accross a wide spectrum of industries including aerospace, defence, medical, electrical, consumer & industrial products.
- Reverse engineering old legacy parts, where drawings & other data maybe missing or outdated. We can bring your old designs to life!
- Design parts which will have the best moulding characteristics to ensure well formed and stable mouldings.
In-House 3D Design & Rapid Prototyping
Using SolidWorks, our in-house engineers create detailed 3D models to visualise moulded and machined components and their interaction within assemblies. This allows potential issues to be identified early, reducing costly revisions later.
Utilising the CAD models, we also offer in house 3D Printing prototyping services, helping validate form, fit and function in the flesh prior to committing to tooling.
Metal to Plastic Conversion Expertise
We specialise in metal to plastic conversions, helping customers reduce part weight, lower production costs by speeding up production schedules, and improve performance without compromising strength or durability.
Our plastic conversion services include:
- Redesigning metal parts which might be machined or pressed and converting them to plastic moulded materials
- Selecting suitable polymers or reinforced materials
- Improving corrosion resistance and design flexibility
- Redesigning metal parts which might be machined or pressed and converting them to plastic moulded materials
This approach often unlocks significant manufacturing and assembly efficiencies, for example by taking small metal assemblies and redesigning it as a single moulded component.
Material Selection & Mould Design Services
Choosing the right material is critical. We provide guidance on thermoplastics, elastomers and specialist materials to meet environmental, mechanical and cost requirements.
Our mould design services focus on:
- Component mouldability
- Tooling options and cavity layouts
- Surface finishes and tolerances
- Production volumes vs tooling investment
- Component mouldability
We analyse component cost against tooling cost to ensure the most economical solution over the full product lifecycle. Where feasible we advocate the use of multi impression tooling which will help bring component price down.
By combining plastic industrial design knowledge with real-world moulding experience, we help ensure your product is designed right – first time.
