Not every plastic part can be usefully recycled in the Injection moulding or in the Custom-made diving equipment manufacture. This is particularly the case with complex geometries, large wall thicknesses or significant variations in wall thickness, where Custom-made moulded parts made from soft PVC could be an interesting alternative.
HAMCO manufactures bespoke moulded parts from soft PVC in accordance with technical specifications. Whether the process is suitable for a specific component depends on its geometry, function, the desired material properties and its intended use.
It is therefore particularly worthwhile to carry out a technical assessment at an early stage when a component is difficult or uneconomical to manufacture using other production processes.
Moulded parts made from soft PVC are particularly suitable for applications involving large wall thicknesses, significant variations in wall thickness, or geometries that are difficult or uneconomical to produce using other manufacturing methods.
Both simple and more complex geometries can be produced as bespoke castings. The specific combination of component geometry, function and material requirements is always the decisive factor.
Thanks to the comparatively high degree of flexibility in terms of wall thickness, it is also possible to manufacture solid soft PVC components for which other manufacturing solutions are not readily suitable.
HAMCO manufactures castings to customer-specific specifications. These may be based on technical drawings, CAD data, samples or specific details regarding the desired function of the component.
The specified component geometry is checked to ensure it can be realised using the relevant manufacturing techniques. If, for example, demoulding cannot be carried out reliably or the geometry is likely to result in increased air entrapment during casting, a Revision of component geometry to suit manufacturing requirements may be required.
Wall thicknesses and variations in wall thickness are also taken into account during the assessment, to ensure that the component can be manufactured reliably and reproducibly.
With technical castings, the focus is often on function, geometry and wall thickness. Depending on the component’s geometry, certain surface areas may arise which, without additional finishing, are not designed to meet high aesthetic standards.
Depending on the component geometry and the required fit accuracy, secondary machining may be necessary. Even if a refined surface finish is required, HAMCO can machine the cast component accordingly after demoulding. Depending on the geometry and requirements, a belt grinding machine can be used for this purpose, for example.
Depending on the component geometry, post-processing enables the necessary dimensional accuracy and fit to be achieved, and allows surfaces to be refined in a targeted manner where this is not possible through the casting process alone.
Do you need a bespoke soft PVC moulded part? Please discuss your technical requirements with us. Based on your drawing, CAD data, a sample or your specifications, we will assess the feasibility of production.
We explain in detail how liquid PVC plastisol is transformed into a finished plastic component – including thick-walled ones – in an open mould, and what the specific features of this process are, at The PVC casting process in the ‘Knowledge’ section. .
