Abstract:
A neck ring for molding a glass container neck finish that includes at least one closure attachment feature. The neck ring includes two semi-annular bi-metal neck ring sections (12, 14), each consisting essentially of a neck ring insert (20, 22) of wear- resistant metal construction and a neck ring body (16, 18) of heat-conductive metal construction different from said wear-resistant metal construction and formed around said neck ring insert so as to embed it in said neck ring body. Each of said neck ring halves has a glass-contacting cavity face that includes a first surface portion (30, 32) formed by said inserts for molding the at least one closure attachment feature on the neck finish and a second surface portion (34, 36) formed by said bodies for molding portions of the neck finish excluding the at least one closure attachment feature.
Abstract:
A method of extending the lifespan of a metal cavity glass bottle mould, includes the steps of machining the entire moulding surface of the mould to remove a surface layer of metal, cladding the machined moulding surface by depositing a layer of filler metal onto the surface in a laser cladding process and machining an exposed surface of the cladding layer so as to remove excess filler metal and return the moulding cavity to its design dimensions. The method includes a method of repairing a metal cavity mould by removing surface defects in the moulding surface of a damaged mould by machining the moulding surface and thereafter cladding the moulding surface. The method extends to the cladding of the moulding surface of an undamaged metal cavity mould.
Abstract:
A coating includes a porous a first layer comprising metal coated solid lubricant particles partially fused together. A second layer comprising a metal or a composite that conforms to the surface topography of the first layer.
Abstract:
A nickel-based alloy for glass-contacting members used in an unelectrified state, having a composition comprising 25 to 40 wt% of chromium, 10 to 45 wt% of cobalt, optionally 0.1 to 3.0 wt% of titanium, and optionally 0.01 to 0.50 wt% of one or a plurality of REMs, and the balance of nickel and unavoidable impurities.
Abstract:
A compact layer (3) of material is formed by thermal projection on a support piece (1) of which at least the surface portion is made of a material having the property of preventing adhesion of this layer (3) on said support (1) and on the adjacent portion (4) of a piece (2) acting as a base for the punch and the support piece (1) is separated from the projected layer (3) by maintaining the integrity, on the one hand of the assembly formed by the projected layer (3) and the piece (2) acting as a base for the punch, and on the other hand, of the support piece (1). The punch thus obtained is comprised of a hollow body with thin walls having a high mechanical strength.
Abstract:
The present disclosure relates to a quench mold (22) that includes an interior cavity and a coating (20,21) on the interior cavity. The coating includes a plurality of particles (20) such as metal-coated particles, superabrasive particles or metal particles in a metal matrix.
Abstract:
An improved mould (10) for use in the production of glass containers such as bottles, jars and the like, the mould (10) includes at least one mould surface defining a cavity (14) which is adapted to receive molten glass, and in which the mould (10) surface is provided with a coating (16) over substantially the whole of the surface, the coating comprising an alloy. The mould (10) is made of segments or partial sections - preferably of two half bodies (12 12a) - with a hollow space (14) in each segment or half body (12, 12a). In the hollow space (14) the coating (16) - comprising an alloy of cobalt and nickel - is metallurgically bonded to the mould (10). The process for producing the mould (10) includes that the coating (16) is fused to the mould (10) by using a two-stage process in which a powder containing the constituent elements of the alloy coating (16) is initially provided, the powder comprises a specially formulated alloy powder in which each particle essentially comprises the elements of the final alloy coating (16) or the coating (16) comprises one or more different powders which maybe mixed together.
Abstract:
A corrosion and erosion resistant article having good release characteristics which includes a metal body having a first surface thereon and a base coat adhered to the first surface has been invented. The base coat comprises at least one layer of inorganic particulate material bonded to the first surface. A second coat adheres to the base coat. The second coat comprises a cured coating of solid particulate lubricant in a phosphate/chromate metal ion solution. A method of applying a corrosion and erosion resistant coating having good release characteristics had been invented. The method comprises providing a metal body having a first surface thereon and applying a base coat to the first surface where the base coat comprises at least one layer of inorganic particulate material bonded to the first surface. The next step comprises partially curing the base coat and applying a second coat that adheres to the base coat, the second coat comprises a cured coating of solid particulate lubricant in a phosphate/chromate metal ion solution. A third coat may be applied.
Abstract:
Cast-iron mold for the production of glass containers by using a ''pressed-blown'' or ''blown-blown'' technique wherein the parts exposed to the parison are coated with a uniform alumina layer of which the thickness is less than 5 micrometers. The invention applies to industrial techniques for producing glass containers such as bottles, flasks, jars or the like.
