84.80 Moulding boxes for metal foundry; mould bases; moulding atterns; moulds for metal (other than ingot moulds), metal carbides, glass, minera? materials, rubber or plastics. - Moulding boxes for metal foundry 8480.20 - Mould bases 8480.30 - Moulding patterns - Moulds for metal or metal carbides : 8480.41 - - Injection or compression types 8480.49 - - Other 8480.50 - Moulds for glass 8480.60 - Moulds for rnineral materials 8480.10 - Moulds for rubber or plastics : 8480.71 8480.79 - - Injection or compression types - - Other This headin covers the moulding boxes used in metal foundry, mould bases and moulding certain exceptions referred to later, it also covers all moulds (whether or not atterns, Einged, and whether used by hand or in presses or mouldin machines) which are of a kind used for moulding the following materials into blanks or finishdarticles : wik (I) Metals and metal carbides. (II) Glass (including fused quartz or other hsed silica) or mineral materials such as ceramic pastes, cement, plaster or concrete. (111) Rubber or plastics. In general, the essential function of a mould is to retain the material in a predetermined shape whlle it sets; some moulds also exert a certain pressure on the matenal. But the heading excludes stamping dies of heading 82.07 since these shape the material solely by means of a powerful blow or compression (e.g., dies for stamping out sheet-metal goods). (A) MOULDING BOXES FOR METAL FOUNDRY These are frames usually of cast iron or steel and usually rectangular or round. They hold the sand mould formed by pressing the sand around a pattern. (B) MOULD BASES These are plates placed on the bottom of the moulds. (C) MOULDING PATTERNS These include foundry patterns, foundry cores, core boxes, moulding boards, pattern plates etc., used in the preparation of sand moulds (generally of wood). (D) MOULDS FOR METAL (OTHER THAN INGOT MOULDS) OR FOR METAL, CARBIDES This group includes : (1) Chill-moulds (die-casts). These take the form of a metallic casing consistin of two or more adjustable parts which reproduce, in hollow form, the shape of the require articles. % (2) Pressure-casting moulds, into which the molten metal is forced under pressure. They normally consist of two complementary metallic chill-moulds, with hollows corresponding to the shape of the required articles in their op osing faces; in some cases the halves of the mould compress the molten metal to a certain egree. S (3) Moulds for sintering metal owders. These moulds are heated. They are sometimes also used for sintering metal carbi$es or ceramic powders. (4) Cylindrical moulds for centrifugal moulding machines (e.g., for casting iron pipes, gun barrels). (E) MOULDS FOR GLASS This group includes : (1) Moulds for glass paving stones, bricks or flags, and compression moulds for glass tiles. (2) Bottle moulds for hand or machine working, including pedal operated moulds (e.g., blank or finishing moulds, ring moulds). (3) Moulds for hollow glassware, for insulators, etc. (4) Shaping moulds for glassmakers' lathes. (5) Moulds made of steel or cast iron, used to make lens or spectacle blanks, etc. (F) MOULDS FOR MINERAL MATERIALS This group includes : (1) Moulds for ceramic pastes (e.g., brick moulds, moulds for pipes or for other articles of ceramics, including moulds for artificial teeth). (2) Moulds for moulding concrete, cement or asbestos-cement goods (tubes, vats, stones, flags, chimney-pots, bannisters, architectural ornaments, wall, floor or roo etc.). Also moulds for making prefabricated construction elements of reinforced or prestressed concrete (window frames, parts of vaulting beams, railway sleepers, etc.). (3) Moulds for agglomerating abrasives into grinding wheels. (4) Moulds for plaster, staff or stucco articles (e.g., toys, statuettes and ceiling decorations). (G)MOULDS FOR RUBBER OR PLASTICS This group includes : (I) "Bladder" moulds for vulcanising tyres. These consist of two adjustable metal chill-moulds, steam or electricall heated, enclosing a kind of air-inflated nn -shaped bag (the air-bag) or hot water-inflate bag (the water-bag), which presses the tyre lrrnly against the mould surfaces. dY tp (2) Moulds for moulding or vulcanising miscellaneous rubber articles. (3) Moulds for making plastic articles, whether or not electrically or otherwise heated; they may operate by gravity, or by injection or compression. The heading also includes preliminary tablettin moulds. These em loy a cold process to consolidate the moulding powders into tablets, eac of which contains &e appropriate quantity of material (and are of a suitable shape and volume) ready for final moulding into the desired article. i The heading also excludes : (a) Forms used in the manufacture of articles (e.g., gloves) b dipping the form into liquid rubber, plastics, etc. (classified according to their constituent materia5 (b) Moulds made of graphite or other carbon (heading 68.15). (c) Moulds of any kind made of ceramics (heading 69.03 or 69.09, as the case may be). (d) Moulds made of glass (heading 70.20). (e) Ingot moulds (heading 84.54). (f) Moulds for the manufacture of semiconductor devices (heading 84.86). (g) Matrices and masters for the production of records (heading 85.23). (h) Subject to the above exclusions, moulds used on presses and other machines, fox the moulding of materials other than those cited in the text of this heading (classified as parts of the machines for which they are designed). -
1.- This Chapter does not cover : (a) Millstones, grindstones or other articles of Chapter 68; (b) Machinery or appliances (for example, pumps) of ceramic material and ceramic parts of machinery or appliances of any material (Chapter 69); (c) Laboratory glassware (heading 70.17); machinery, appliances or other articles for technical uses or parts thereof, of glass (heading 70.19 or 70.20); (d) Articles of heading 73.21 or 73.22 or similar articles of other base metals (Chapters 74 to 76 or 78 to 81); (e) Vacuum cleaners of heading 85.08; (f) Electro-mechanical domestic appliances of heading 85.09; digital cameras of heading 85.25; (g) Radiators for the articles of Section XVII; or (h) Hand-operated mechanical floor sweepers, not motorised (heading 96.03). 2.- Subject to the operation of Note 3 to Section XVI and subject to Note 11 to this Chapter, a machine or appliance which answers to a description in one or more of the headings 84.01 to 84.24, or heading 84.86 and at the same time to a description in one or more of the headings 84.25 to 84.80 is to be classified under the appropriate heading of the former group or under heading 84.86, as the case may be, and not the latter group. (A) Heading 84.19 does not, however, cover : (i) Germination plant, incubators or brooders (heading 84.36); (ii) Grain dampening machines (heading 84.37); (iii) Diffusing apparatus for sugar juice extraction (heading 84.38);
