Abstract: A skate includes a skate boot with two opposed boot side portions extending from heel and ankle portions to a forward edge of the boot side portions. A forward-most eyelet is the eyelet closest to the forward edge. A toe cap is connected to the skate boot at a front end, and the toe cap has toe cap side portions extending rearwardly to a rear edge of the toe cap disposed forward of the forward-most eyelet. A toe cap extension extends rearwardly from the rear edge of the toe cap and over a portion of the boot side portions defined rearward of the forward edge and below the forward-most eyelet. The toe cap extension engages the portion of the skate boot and allows movement of at least the skate boot rearward of the forward-most eyelet during formation of the skate boot or use thereof.

Abstract: A method of method of manufacturing customized inserts for a boot, such as a skate boot, that is at least partially thermoformable includes receiving numerical data corresponding to a tridimensional shape of a wearer's foot, and manufacturing a medial side insert and a lateral side insert based on the tridimensional shape of the wearer's foot. The medial side insert and the lateral side insert are shaped to be insertable into the boot with a core that is dimensioned to generally correspond to a foot size of the boot, with a medial internal surface of the medial side insert and a lateral internal surface of the lateral side insert abutting respective outer surfaces of the core.

Abstract: A method of customizing a boot, for example a skate boot, includes generating a tridimensional digital representation of a wearer's foot using numerical data obtained by scanning the wearer's foot. A boot with a foot size corresponding generally to a foot length of the wearer's foot is selected. A core is also selected. The core, a medial side insert and a lateral side insert are inserted into an internal space of the boot such that the medial side insert and the lateral side insert straddle the core. The medial side insert and the lateral side insert are manufactured based on the tridimensional shape of the foot. At least a portion of the boot is then heated such that the boot is thermoformed to follow surfaces of the medial and lateral side inserts. The core, the medial side insert and the lateral side insert are then removed from the boot.

Abstract: Uniform hardenability is achieved in plastic injection mold and die block tooling of 20 inches and larger by the use of 0.05-0.20 vanadium in conjunction with low carbon steel in which ingots are hot worked to form mold and die blocks having cross sections of 20 inches and larger followed by water quenching and tempering.

Abstract: This invention pertains to plastic injection mold tooling, and also large forgings, formed from a low carbon mold steel having markedly increased hardening and hardenability properties in large sections as contrasted to currently available commercial products. The above attributes are obtained together with equal or better machinability and improved mold parting line wear. When manufactured in conjunction with a double melt process, this invention can improve significantly polishing characteristics and other attributes of molded parts in tooling sets.

Abstract: A blemish free surface is formed on the cavity side of a set of mold or die blocks, said set consisting of a core side and a cavity side, by use of a softer alloy on the core side as contrasted to the cavity side so that, during plastic injection molding, the core side will wear at the parting line in preference to the cavity side whereby erosion of the set occurs on the core side in preference to the cavity side leaving the cavity side erosion free.
