The shock-absorbing properties The edge protection caps and the accuracy of the customer-specific profile cross-section geometries are the remarkable features and benefits dipped protective caps For example, extruded aluminium profiles. Unlike hard plastics such as Polyethylene (PE for short) or Polypropylene (PP for short)are the rubber-flexible Covytec soft PVC types The ideal material for use as transport protection caps, bearing protection caps and end caps in a wide range of industrial applications. Industries.
In contrast to injection moulding, the PVC dipping process is a pressureless manufacturing process for the production of edge protection caps made of PVC or polyvinyl chloride. The dipping cores, which are heated in an oven and then dipped into a tank filled with liquid PVC plastisol, precisely replicate the outer contour of the steel or aluminium profiles to be protected. The length of the edge protection caps is determined by the immersion depth and the wall thickness by the dwell time of the immersion cores in the immersion basin.
Already in the preliminary discussion for the preparation of the offer, it must be determined for Edge protection caps for hollow chamber profiles or small cross-sections, it must be clarified whether the internal profile geometries should also be formed with the dipped part and what influence this may have on the mountability.
The process of manufacturing PVC dip moulded parts We describe this in great detail with general design, assembly and quality information on the product pages of the PVC round capsthe Rectangular caps, the product page of the Coating of metallic components and in the knowledge section under Manufacturing processes.
Our PVC dipped parts are manufactured with a salt-free heat transfer system - completely without lithium nitrate or potassium nitrate - for Maximum purity and safety. The result is particularly clean, dimensionally stable and durable PVC dipped parts and PVC coatings that meet the highest quality requirements - manufactured in an environmentally friendly way, with improved occupational safety and easier disposal.
*Light colours that are exposed to outdoor weathering can be made UV-stable by adding a formulation ingredient. Dark colours such as black and anthracite grey are generally UV-resistant.
As both the base material (PVC plastisol) and a UV stabiliser have a yellowish inherent colour, the accuracy of the RAL colour shade is minimally affected. We confirm the colour shade similar to the RAL number.
The flexibility of Covytec PVC materials ensures that the technically smooth inner contour of the PVC edge protection caps fits snugly and securely onto the outer wall of the standard or customised profile to be protected.
A simple structure of the Dipping tools, especially in the case of customised profile cross-sections ensures that we can offer you the best possible service with our excellently equipped in-house Toolmaking measurable Cost and time benefits in the realisation.
We are firmly convinced that there is a high probability that many of the products you have procured to date or for the Injection moulding process developed injection-moulded protective caps from polyolefins such as PE, PP replaced by dipped edge protection caps can be realised.
The Wall thickness is measured non-destructively at the open end of the cap.
Due to the process, it continuously increases towards the closed end of the immersed caps.
Drain marks and drain drops At the closed end, they cannot be completely avoided due to the nature of the process.
In the food industry, the detectability of the PVC material is a basic requirement for the use of edge protection caps. We can meet this requirement without restriction by adding certain formulation components. In our Blog post Detectable caps the topic will be discussed in detail.
