Molded loose grain inspection tools and method
A method for molding or replicating leather samples for inspection, selecting and later using those samples in applications such as automobile interiors with leather surfaces that are laminated or have a loose grain appearance. In one process variant, the main steps include choosing original samples for replication, the original samples including a characteristic to be replicated; making a replication tool from the approved samples; and producing replicated molded samples with the replication tool that emulate the original samples, thereby enabling the replicated molded samples to be compared with the original sample.

FLEXIBLE MOLD SEGMENT WITH SIPE ELEMENT HAVING A PROJECTION FOR USE IN FORMING A TIRE
A mold segment (10) for forming a tire is provided that has a sipe element (14) with first and second ends. A first side face (20) is oppositely disposed from a second side face (22) in a width direction, and a bottom is oppositely disposed from a top in a height direction. The sipe element has a projection (30) that extends from the first side face. A mold segment base (32) made of a material that is more flexible than material making up the sipe element (14) is present. The mold segment base receives the sipe element such that the bottom of the sipe element is located inside of the mold segment base and the top of the sipe element is located outside of the mold segment base. The mold segment base defines a cavity (34), and the projection (30) is located inside of the cavity (34). The mold segment (10) is used for forming a production mold segment (68) that ultimately molds a green tire into a cured tire (12).
MANUFACTURING METHOD OF MASTER TEMPLATE AND STAMP OF GRATING OF DIFFRACTIVE OPTIC ELEMENT, MASTER TEMPLATE AND STAMP
A manufacturing method of a master template (20) of a grating of a diffractive optic element. A layer (250) of material (200) is deposited on a substrate (108) of the master template (180) through perforations (204) of a plate (202), cross sectional areas of the perforations (204) depending on locations of the perforations (204) in the plate (202), and the plate (202) and the substrate (108) being spaced at a non-zero distance (D) from each other. Height of the at least one layer (250) on the substrate (108) is caused to vary with variation of the areas of the perforations (204). Raised formations (180) are formed on the substrate (108) by removing the at least one layer (250) from areas, which result in lowered formations (182) between the raised formations (180). A fill factor and height of the raised formations (180) are made to be proportional with each other while the raised and lowered formations (180, 182) have a relation with grooves (902) and ridges (900) of the grating (904), the relation depending on the proportionality.
Method for producing a profile segment of a segmented casting-vulcanizing mold for vehicle tires and a vulcanizing mold and a vehicle tire
A method is for producing a profile segment of a segmented casting-vulcanizing mold for vehicle tires, the molding area of which molds a segment of the tread profile of a tire to be vulcanized, including the steps: creating a rigid model segment having a casing-like tread surface; milling the profile positive of the tread into the casing-like tread surface of the model segment to obtain the master model; creating a flexible impression from the master model; creating a rigid plaster cast from the impression to form a casting core segment; casting all of the annular, placed-together casting core segments with an aluminium-magnesium alloy to obtain a vulcanizing mold, subsequently divided into profile segments. A plasma coating is applied to the tread of the model segment, into which the profile positive of the tread is subsequently milled to obtain the master model. Plasma coating gives the master model a defined roughness.
Systems and methods for making and using a fitted cap for applying a shaped sealant shroud to a portion of a fastener
A system (200) for making a fitted cap (300) comprises a fastener template (202), dimensionally identical to a portion (106) of a fastener (100) and extending from a support plate (210), and a first plurality of through-openings (212) penetrating the support plate (210) and arranged about the fastener template (202). The system (200) also comprises a precursor cap (320) that is geometrically complementary to the fastener template (202), first means (217) for heating a first polymer sheet (270), and second means (219) for applying suction to the first polymer sheet (270) through the first plurality of through-openings (212) to vacuum-form the first polymer sheet (270) over the precursor cap (320). After vacuum-forming the first polymer sheet (270) over the precursor cap (320), at least a portion of the first polymer sheet (270) forms the fitted cap (300). The fitted cap (300) is configured to apply a shaped sealant shroud (590) to the portion (106) of the fastener (100).
Scalable manufacturing of superhydrophobic structures in plastics
Disclosed are methods of manufacturing a SH surface including: creating a master with SH features by: depositing a rigid material onto a first surface, wherein the first surface is a shrinkable platform; shrinking the first surface by heating to create a SH surface, wherein the SH surface has micro- and nano-scale structural features that trap air pockets and prevent water from wetting the surface; forming the master by molding an epoxy with the shrunken first surface having a SH surface, wherein the master acquires the SH features of the first surface; and imprinting the SH features of the master onto a second surface to impart the SH features of the master onto the second surface. Some embodiments relate to a superhydrophobic (SH) surface, an article including a SH surface as disclosed, such as a microfluidic device or a food container.
