DEFINITION

Classification: 106/38.2

Compositions which are (a) specialized for use in making molds, (b) specialized for use in coating molds, or (c) molds claimed solely in terms of the composition of which they are composed.

(1) Note. The molds and mold compositions included in this subclass are intended for use in plastic shaping processes such as casting, injecting, film spreading, etc., regardless of the material shaped. For the purpose of classification in this and indented subclasses, such shaping members as patterns, matrices, cores and film casting surfaces are all considered to be molds.

(2) Note. For molds and analogous devices claimed in terms of significant mold structure, whether or not the composition of which the mold is composed is also claimed, the Search Class notes below referencing this (2) Note should be consulted

(3) Note. Molds mentioned by name only and defined by a single material other than a composition of which the mold is made, are classified on the basis of such material. In this connection, the Search Class notes referencing this (3) Note should be consulted.

(4) Note. Search this class, appropriate subclasses, for similar compositions which are not specialized for use in making or coating molds.

SEE OR SEARCH CLASS

148, Metal Treatment,

400+, for molds which are stock resulting from processes of treating metals classifiable in Class 148, or are stock distinguished only by the internal structure or characteristics of the metals, metallic compositions or alloys comprising such products. (see (3) Note above) 164, Metal Founding, appropriate subclasses, particularly

520+, for processes of making molds from particular material subclass 138 for processes of casting metal in a mold of a particular composition and subclasses 349+ for sand molds or cores. (see (2) Note above)

249, Static Molds,

134+, for molds having a particular structure composed of a specific composition; see (2) Note above. (see (2) Note above)

260, Chemistry of Carbon Compounds see (3) Note above.

264, Plastic and Nonmetallic Article Shaping or Treating: Processes,

219+, for processes within the class definition including the step of making the mold (including mold making, per se) and subclasses 337+ pertaining to the use of particular mold materials. (see (2) Note above)

420, Alloys or Metallic Compositions, appropriate subclasses for molds claimed solely in terms of the metal or alloy of which they are composed. (see (3) Note above)

423, Chemistry of Inorganic Compounds, see (3) Note above).

425, Plastic Article or Earthenware Shaping or Treating: Apparatus, appropriate subclasses for a molding machine for manufacturing nonmetal products, especially see

175+, for such apparatus for forming a mold. (see (2) Note above)

427, Coating Processes, 133+, for processes of coating, per se, wherein the substrate is disclosed as a mold.

428, Stock Material or Miscellaneous Articles, appropriate subclasses for a coated mold, where no significant mold structure is claimed, especially

411+, for a composite, nonstructural product distinguished only by the compositions of the layers and subclasses 544+ for molds claimed in terms of metallic stock.

508, Solid Anti-Friction Devices, Materials Therefor, Lubricant or Separant Compositions for Moving Solid Surfaces,

and Miscellaneous Mineral Oil Compositions, appropriate subclasses for compositions whose purpose is to impart lubricity to moving surfaces. A search in Class 508 may be appropriate to ensure a complete search.

520, Synthetic Resins, for a composition for making or coating a mold, particularly Class 523,

139+, for compositions relating to metal foundry molding or metallurgical furnaces. (see (2) Note above)
