Services

At Seaborne Plastics we take your ideas from concept to production-ready parts with speed, precision and engineering confidence. From the earliest design review to finished assemblies ready for delivery, we integrate expertise, technology and quality control to support every stage of your project, whether you are launching a new product or scaling existing production.

Design

We work closely with your team from the outset, providing technical guidance on design, materials, and manufacturing methods to ensure your part is right first time.

By integrating seamlessly with your development process, we help reduce risk, avoid costly redesigns, and shorten lead times — allowing you to move forward with confidence.

Tool Making

The best parts start with the best tools, and it is always our priority to ensure your design and production requirements are met with cost-effective and reliable tooling for prototype, small batch or high-volume serial production.

To achieve excellent part quality and consistent output from our thermoforming machinery, we recommend temperature-controlled aluminium mould tooling as standard for production parts.

Vacuum Forming

Vacuum forming sits at the heart of our manufacturing capability. Using controlled heat, pressure, and precision tooling, we form flat thermoplastic sheets into complex, repeatable components. With capacity ranging from 100mm x 100mm up to 2500mm x 2200mm, we support projects of all sizes, from small technical parts to large structural panels. Where required, we also utilise complementary processes including drape forming, blow moulding, and line bending to meet specific design and performance needs. Our Geiss forming machines, many equipped with automatic sheet loaders, deliver consistent, high quality parts from the first machine cycle, supporting efficient and reliable production.

CNC Trimming

Our advanced 5-axis CNC trimming platforms deliver fast, high-precision finishing on complex vacuum formed components. With automatic tool changers and a working envelope of up to 4.5 x 4 x 1.5 metres, we machine everything from intricate technical parts to large structural panels with equal control and accuracy. Every component is located in a purpose-machined trim jig, ensuring dimensional consistency, repeatability and cosmetic quality across serial production.

Select machines are equipped with true linear motor drives combined with direct linear scale measurement. This technology significantly increases machine dynamics and positional precision, reducing cycle times while enhancing repeatability and cut quality, particularly on tight-tolerance or high-complexity components.

With multiple CNC platforms operating in parallel, we provide built-in production redundancy, safeguarding continuity of supply and supporting dependable lead times for demanding programmes.

PU Foaming

We use high-precision pressurised dosing machines to apply rigid polyurethane foam to vacuum formed components. This process adds structural strength, improves rigidity, and provides excellent thermal and acoustic insulation. It’s ideal for strengthening large panels or creating insulated parts for transport, refridgeration, and appliance applications without adding unnecessary weight.

Adhesive Bonding

Our operators are externally trained in structural adhesive bonding to the rigorous standards of the automotive and rail industries. This expertise delivers consistent, reliable bonds across subassemblies and enables the manufacture of tougher, more capable components than vacuum forming alone, including multi-part and reinforced assemblies designed to perform in demanding environments.

Assembly

Skilled technicians provide assembly services that deliver finished, production-ready products. From mechanical fixings and precision riveting and welding to deburring and final detailing, every step is carried out with care and consistency. Where required, we work closely with trusted local partners for painting operations and hard coating polycarbonate components, ensuring finish and performance requirements are met. Whether supplying individual components or complete sub-assemblies, we ensure parts leave our facility ready to ship and built precisely to your specification.

Recycling

We operate a fully controlled closed loop recycling system for production waste, supported by in house sorting and granulation. This delivers consistent, high quality, dust free recyclate that is returned to our extrusion partners and reprocessed into new plastic sheet. By controlling material flows end to end, we enable higher recycled content while ensuring a superior and consistent surface finish on our recycled sheet materials. This approach supports material traceability, waste reduction, and lower environmental impact across the supply chain, backed by our ISO 14001 certified Environmental Management System.

3D Scanning

Seaborne Plastics utilises 3D scanning technology for reverse engineering as well as process quality control of formed and trimmed components. High resolution scans allow us to accurately capture existing parts, verify critical features and compare finished components against CAD data. This capability supports rapid reproduction of legacy parts, tighter process control and greater consistency across production runs.

Quality

We operate a dedicated quality department supported by trained inspection personnel and a robust ISO 9001 certified Quality Management System. Our temperature controlled inspection facility is equipped with a granite reference table and FaroArm measuring system, enabling accurate and repeatable dimensional verification. Full drawing, revision, and specification reviews are completed at order entry, followed by first off inspection at production start and documented in process and random inspections throughout each run. Where required, we support PPAP documentation, including dimensional reports and inspection records, providing traceability, control, and confidence that every component consistently meets specification.
