Precision Polyurethane Mouldings

Design

From the outset, our technical staff provides help and guidance (building in added value and/or cost savings) on component design. We put particular focus on the process requirements and the selection of correct material.

Tolerances/Wall Thickness

Standard wall thickness are 3-4mm, but this can be reduced to 1.5mm in local areas or indeed increased to the required thickness, whilst ribs, bosses and other changes in thickness can be achieved. The general tolerance criteria is ±0.3mm up to 300mm (±0.1mm per additional 100mm thereafter).

Inserts

Features normally requiring separate machining operations including threads, studs, bushes and complex apertures (e.g. ‘D' holes) can be included in components to reduce post finishing operations and reduced product costs.

Mould Tooling

Tools and mould tooling is manufactured to very high standards using the latest developments in resin, plastic and composite materials. We combine traditional skills with 3D CAD/CAM facilities and CNC Machining technology to produce high quality tooling and components quickly and economically.

Additional Processes

Paint spraying facilities are used to finish components using conventional acrylic paints, whilst EMI and RFI screening can also be applied.

Machining

Cast material densities allow threaded holes to be introduced directly to the material, as well as other machining operations that cannot be incorporated in the mouldings.

Component Materials

Using the latest advances in polyurethane technology, we produce components that are strong, dense and impact resistant or soft and malleable. Material specifications can be supplied on request and fire retardant material (UL 94/VO specification) is available.

Finishing and Assembly

We undertake full product assembly and packing, using either free issue or brought in parts and packaging, to provide further customer cost savings and avoid additional handling problems.

Inspection and Quality Control

Quality is monitored throughout the manufacturing process, with regular inspections using specific gauges and jigs together with conventional measuring equipment. The dedication to quality control - as specified in our QA manual, conforming to ISO 9001 standards - ensures consistently high standards are maintained.

Communication

We can accept design briefs via email, PDF, DXF and CD ROM. Ideally, information should be in 3D solid model formulated IGES backed up by 2D. Machining Programme will be generated directly from 2D DXF files supported by 3D IGES files and 2D PDF. Please email your enquiries to: info@castech.co.uk

We look forward to hearing from you.
