Rotomoulding can produce a
variety of complex shapes
Rotational moulding - perfect for hollow or partially hollow plastic components
- In rotational moulding, polymer powder is slowly tumbled in a heated, enclosed mould. The powder melts, forming a coating over the internal surface of the mould. The mould is cooled, allowing the polymer coating to become solid. The mould is opened, and an accurately shaped part is extracted
- The piece can include features such as metal inserts, threads, CNC machined edges, holes, slots, etc
- Almost any finished appearance can be achieved with texture or paint
- tecni-form have the capability to create assemblies of moulded and bought-in parts.
Rotational moulding is a highly versatile method for making precise, stress and seam free plastic components at comparatively low cost. The process can produce complex shapes with controlled wall thickness in a variety of materials. It is particularly suitable for manufacturing hollow or partially hollow pieces.
By selecting from a range of different materials, articles with physical properties as varied as flexible gearstick gaiters or rigid commercial vehicle cab components can be made. Metal inserts such as threads and bushes can be moulded in, and moulded cavities filled with foam. Alternatively, threads may be part of the moulded shape itself. Mouldings may be CNC machined, drilled, sawn, routed, tapped or welded.
A moulded textured surface enhances appearance, and improves scratch resistance - tecni-form have almost unlimited choice. The look and feel of other materials such as metal and leather can be simulated. If more rigidity or insulation are part of the design, an inner foam layer can be moulded integrally or after moulding injected into hollow sections. Take a look at the Finishes section to see what can be done.
An enormous range of products
can be produced with rotomoulding
tecni-form go a step further: they build up complete and often complex assemblies from plastic and metal parts, the result ready for the customer assembly line.
