Definitions

  • This invention relates to a method of masking a selected area or selected areas of tubular components prior to treating unmasked surface areas.
  • the invention also relates to a mask for use in the masking method.
  • the relevant surface or surfaces of the tubular component are treated in the manner required.
  • the surface treatment may comprise spraying or otherwise depositing a layer of metal or alloy, adhesive coating, paint spraying, sand-or aqua-blasting or surface etching for example.
  • a method of masking a selected area or selected areas of a tubular component prior to treating unmasked surface areas comprising fitting a re-usable masking element to the tubular component, the tubular component and/or the masking element resiliently deforming so as to be urged together over the selected area or selected areas of the tubular component.
  • the re-usable masking element may comprise a tubular member for fitting within one end of the tubular component to mask an area of the inside surface adjacent that end.
  • the inner end of the tubular mask element is chamfered around its inner edge: if a layer of e.g. metal is then applied to the unmasked inside area of the tubular component, when the mask element is removed it leaves a clean edge to the applied metal layer.
  • the re-usable masking element may comprise a tubular member for fitting around the outside of the tubular component to mask an area of its outer surface.
  • the masking element may comprise a cap member for fitting to the end of the tubular component, and having inner and outer circumferential skirts for fitting against the inner and outer surfaces of the tubular component.
  • re-usable mask may comprise a flexible or semi-flexible tubular member of resilient material and of outer diameter greater than the inner diameter of the tubular component which is to be masked over a selected area of its inner surface.
  • This tubular mask member can then be folded or kinked along its length, inserted into the tubular component and then allowed to expand under its own resilience so far as the inner diameter of the tubular component will permit, thus pressing firmly against the inner surface of the tubular component over a portion of its circumference.
  • FIG. 1 there is shown a heat-­shrinkable tubular component 10 of plastics material.
  • a re-usable masking element 12 has been inserted into one end of the component 10 to mask a selected area of the inner surface of the component adjacent that end.
  • the masking element 12 comprises a precision-made tubular member, which may be machined or moulded, and is pro­vided with a chamfered edge 14 to its inner end. If the surface treatment which the unmasked area of the tubular component 10 is to receive involves high temperatures, the element 12 is formed of temperature resisting material e.g. PTFE.
  • the tubular masking element 12 is pushed into the end of the component 10 to the position shown.
  • the element 12 has a slightly greater outer diameter than the inner diameter of the component 10, but forces the component 10 radially outwards against its own inherent resilience.
  • the masking element is firmly in engage­ment with the tubular component 10 over the selected area, such that this area is effectively and securely masked.
  • the required surface treatment to the unmasked area(s) of the component 10 can then be carried out.
  • this treat­ment comprises the application of a layer of e.g. adhesive or metal
  • the chamfered edge 14 of the masking element ensures that this element can be removed and leave a clean edge to the applied layer of e.g. adhesive or metal: if instead the end of the element 12 was flat, there would be a build up of the applied material of the layer against it, such that the layer would tend to tear at its junction with the element 12 upon removal of the latter.
  • Element 22 is in the form of a cap having inner and outer circumferential skirts 23,24 which are spaced apart to receive an end por­tion of the component 10 therebetween.
  • the annular space between the two skirts 23,24 is slightly less than the wall thickness of the component 10, so that the latter will be compressed slightly against its own inherent resilience and therefore the skirts 23,24 press firmly against the inner and outer surfaces of the component 10. This again provides for effective masking of the areas concerned.
  • a re-usable masking element in the form of a flexible or semi-flexible tubular member 32 of outer diameter greater than the inner diameter of the tubular component 10.
  • the masking element is inserted into the component 10 by folding or kinking it along its length as shown, then pushing it into one end of the component 10 and releasing it.
  • the element 32 then expands radially under its own resilience, as far as the inner diameter of the component 10 will allow.
  • the masking element thus presses firmly against the inner surface of the component 10 over a substantial portion of the cir­cumference of the latter.
  • each of the masking elements which have been described can be removed readily from the tubular component, after the required surface treatment of the unmasked area(s) has been carried out. The masking elements can then be re-used.
  • tubular component which is masked may be of any desired cross-­sectional shape (e.g. circular, square, elliptical etc) and its cross-sectional shape and/or size may vary along its length.
  • the masking element may also be of any desired cross-sectional shape and may similarly vary in cross-sectional shape and/or size along its length.
