Abstract
A method of casting flat or relatively flat panels is described. A casting surface is produced by drawing down a plastics film sheet (8) on to a relief structure arranged on a vacuum table (12). The relief structure may be formed of separate plural components or a quantity of configurable material (6). The top of the plastics sheet accordingly adopts a relief configuration defined by the relief structure or by the arrangement of the configurable material (6) underneath it. The configurable material may be granular or particulate, and/or incorporate objects such as letters or pictograms. A castable material 10, for example fibre reinforced polymeric plaster mix, is then placed on top of the plastics film sheet (8), which may be substantially gas impermeable, and allowed to set. The edges of the panel are preferably defined by a frame (7). A sheet of geotextile material 5 is placed over a filter (3) (figure 1 — not shown) to prevent fine material penetrating into the table itself.
Description
MANUFACTURE OF CAST PANELS
This invention relates to the manufacture of cast panels, particularly panels having a relief surface where the relief may take the form of a texture, a graphic design, including lettering and symbols, and combinations thereof.
A classic approach to the manufacture of a relief surface panel is to construct a mould from a pattern which is the shape of the surface desired, apply a layer of castable material to the surface of the mould, cause or allow the castable material to harden or set and then part the set cast material from the mould.
This naturally requires the mould not to be re-entrant since otherwise the cast panel would be physically locked to the mould. Even if care is taken in mould manufacture, it is often difficult to separate the two, particularly if the adhesion between the cast material and the surface of the mould is substantial. It is customary to cover the mould surface with some sort of "mould release agent" prior to casting material against it. Separation of the mould and the cast material is easier if the mould is made of silicone rubber, the elasticity and resilience of which enable it easily to be stripped away from the cast material and then re-used. The manufacture of a mould from silicone rubber, however, is not inexpensive, particularly if the panel to be cast is of substantial size such as may be required, for example, for architectural cladding applications.
I have now found that the problem of separation may be alleviated by using as the mould a plastics film which is held against a relief structure by a pressure differential across it, and applying the castable material on top of the film.
It is found that working this way, and using a vacuum table as the support for the relief structure, with the film being drawn down by suction on to the relief structure, the surface of the film against which the castable material is cast is very firm, so enabling the castable material to be worked firmly on to the surface of the mould without thereby causing any deformation. In contrast, a silicone mould can be deformed during the application of the casting material, and in order to keep deformation to a minimum it is usually necessary to back the silicone mould with a support, for example of plaster or glass reinforced plastics material. Avoiding this provides a further advantage of the method of the present invention.
The use of a plastics film ensures that the surface against which the castable material is allowed to set or harden is not re-entrant and, once the pressure differential is removed, the plastics film may be easily separated from the underlying relief structure, and then easily pulled away from the cast, set or hardened material of the panel itself.
A highly preferred way of arranging the film is to draw it downwards against a relief structure by the use of a vacuum table. This may be achieved, if the area of the vacuum table is sufficiently large relative to the area of the panel to be cast, simply by laying the film over the relief structure and applying the vacuum. If desired, and particularly if the film and table are not much larger than the area of the relief structure, the film may be sealed at its edges to the table, e.g. with adhesive tape. This enables a faster and more effective draw-down to be achieved, but does involve the extra step of unsealing the edges of the film from the table after casting and before the removal of the casting and film from the relief structure.
The relief structure may be a unitary structure, but a major advantage of the casting method of the present invention is that it may also be made out of a plurality of units. These are held in place once the vacuum is applied, but, prior to that, can be moved around at will. The relief structure may thus be formed in one or more sections and from a wide variety of materials. In particular, it may be made from a configurable material, such as a particulate material, or from a number of relief-imparting members, for example letters or numbers, in each case being located on a suitable base. The size of the particles of configurable material may vary, for example from a sand or powder type of material through to granular materials, or even to large particulate materials, such as gravel or pebbles, or individual items such as marbles, nuts or pasta. A particular configurable material is a set of indicia which can be arranged to enable the production of a cast panel bearing a relief legend. The material may include objects or symbols.
Thus, according to a specific aspect of the present invention, there is provided a method of producing a flat or relatively flat panel of cast material which comprises the following steps: 1 placing a quantity of configurable material on to a generally horizontal
vacuum table;
2. configuring the material to a desired arrangement and to a desired overall surface shape; 3. placing a substantially gas-impermeable film over the configurable material on the vacuum table; 4. applying vacuum or suction to pull the film down against the table so as to hold the configurable material in a fixed configuration and provide a relief casting surface; 5. applying to the casting surface a quantity of a settable, spreadable moulding composition; 6. causing or allowing the composition to set; and 7. separating the set panel from the film against which it was cast.
Preferably the edges of the panel are defined by the use of an appropriate frame surrounding the quantity of configurable material. The shape of the frame may be varied to suit the desired final panel shape. The depth of the frame is preferably substantially that of the thickness of the final cast panel The frame may be made up of a number of sections, or may be an integral fixed frame. The frame may also be made up of a configurable material such as a flexible rubber strip.
If it is desired to cast a gently curved or even an undulating panel, then the upper surface of the vacuum table may be modified by applying, for example, a layer of sand or similar granular material which is then moved to provide, for example, a shallow curved bed or an undulating bed. It is sometimes of assistance to lay a sheet of permeable material, for example a so-called geotextiie sheet, over the sand so as to keep it separate from the configurable material which is then placed on top.
The moulding composition which is applied to the casting surface may be chosen from a variety of castable hardenable compositions. The preferred materials are fibre mesh reinforced polymerised plaster mixes. These may be pigmented to provide a panel of the appropriate colour and they may also include a quantity of particulate material such as a fine aggregate to impart a desired texture, for example of stone, to the final cast panel surface.
Fast-setting concrete mixes may also be used. In a further development, a plaster or settable ceramic material may be used to make a panel which is then in turn used as a mould for a hot casting process, for example having molten metal or hot glass cast against it.
If desired, appropriate fixing means may be located in the moulding composition so that once the composition has set, the fixing means are firmly embedded within it and may then be used to assist in fixing the panel in the desired position.
The invention is illustrated in the accompanying drawings which show diagrammatically how the method is put into practice. In the drawings: Figure 1 is a diagrammatic perspective exploded view of a vacuum table for use, in the present invention; Figure 2 is a vertical section through the exploded view; Figures 3 and 4 a vertical section and perspective view of the assembled
table;
Figure 5 is an exploded view diagrammatically showing the items which are sequentially placed on the table; Figure 6 a diagrammatic perspective view of the material so placed; Figure 7 shows the addition of the moulding material; and Figure 8 is a plan view of a cast panel.
Referring to the drawings, a vacuum table 12 consists basically of a flat tray or pan 1 having a depending vacuum port 4 underneath it. Set in the pan 1 is a gas-permeable panel 2 consisting of a geotextile sheet having formed in it an array of conical projections, over the top of which lies a sheet of filter material 3. This arrangement is strongly resistant to vertical compression and does not collapse when vacuum is applied, while the conical array promotes even evacuation of the table. The filter stops dust passing through into the table and reaching the vacuum pump.
Figure 5 shows the sequence of operation. First of all, a sheet of geotextile material 5 is placed over filter 3 to prevent fine material penetrating into the table itself. A suitable material is 10 mm thick felted polypropylene fabric, hole-punched to allow the passage of gas or liquid, for exampJe as used in marine defences to prevent erosion.
On top of this, denoted 6, is placed a quantity of configurable material, for example a quantity of pasta shapes.
A rectangular metal frame 7 is shown, the major dimensions of which correspond to those of the intended panel and the thickness of which corresponds to the thickness of the intended cast panel.
Finally, when the configurable material has been moved by hand into an appropriately attractive shape within frame 7, a gas impermeable film 8, for example a sheet of blown 3-layer polyethylene of thickness 25 micron, is draped over the table which it overlaps at 9 and a suction pump then switched on to exhaust the air from within the table via port 4. This pulls the film 8 down on to the configurable material and holds the entire assembly firmly in place.
Once that has been achieved, a quantity of casting material 10 is simply poured on to the centre of the frame and quickly spread out and e.g. trowelled relatively flat, or it may be sprayed on. The upper surface is going to be the back of the panel and accordingly does not need to be particularly smoothly finished. If it is desired to reinforce the panel, one or more layers of monofilament mathng may be dropped into the frame between the application of a first quantity of the casting material and a final quantity. The casting material applied may itself vary, for example starting with an unreinforced gypsum plaster mix to produce a smooth surface finish and finishing with a final backing coat of plaster containing chopped glass fibre -e.g. 12-25 mm long fibres -to provide increased flexural strength to the final cast panel.
The vacuum is then maintained to hold everything still while the casting material 10 is allowed to set. After that has occurred, the vacuum is released and the cast panel may then simply be lifted up by raising the plastics sheet 8.
The plastics sheet 8 may then be pulled away from the front of the cast panel and, as indicated in Figure 8, seen from the front (i.e. seen from the underneath in the casting position) there is a rectangular panel with a textured shape in relief on it. The configurable material 6 may be scooped up for re-use if desired or left in position and a second panel cast in the same way.
The present invention is of particular value in casting architectural relief panels, particularly if carried out as a two-stage process. For example, in a first stage, a desired panel design may be laid out on the vacuum table using configurable material, and any relevant relief sections, for example raised letters. When the design is judged satisfactory -by eye -the plastics film is laid on top and vacuum applied and a cast panel made -as described above. The finished cast panel is then inverted and placed on the table to constitute a relief pattern for the sequential production of a plurality of relief panels, each of which replicates the original relief structure which was constructed on top of the vacuum table in stage 1.
