Embodiments of the present disclosure generally relate to imprint lithography, and more particularly to methods and apparatus for creating a large area imprint without a seam. Methods disclosed herein generally include separating the curing time of the features in a stamp or product from the curing time of the seam and the periphery. The seam and periphery can be cured first or the seam and periphery can be cured last. Additionally, the seam curing operations can be performed on the master, on the stamp, or on the final product.

Some embodiments of a compression mold for forming a rib-and-sheet part includes a mold cavity and a mold insert. A sheet is placed in the mold cavity, and the mold insert is placed on the sheet. A preform assemblage is placed in a gap that is formed between the mold insert and the wall of the mold cavity. A mold core is biased above the preform assemblage, prior to molding operations, via a compression spring.

A method of producing a fiber-reinforced resin by press-molding a prepreg preform contains a reinforcing fiber and a thermosetting resin, the method including (a) a preform production step of producing a preform; (b) a placement and preheating step of placing the preform in a mold and preheating the preform; (c) a pressing step of changing the preform into a product shape; and (d) a curing step of curing the preform while pressurizing the preform, wherein, at start of the pressing step (c), a degree of cure e of the thermosetting resin in a specific part of the preform is higher than a degree of cure i of the thermosetting resin in a region other than the specific part of the preform.

Exemplary embodiments of the present disclosure are directed towards methods and apparatus for molding-in gaskets that serve as light blockers, within the grooves of a moving planar work material. The gaskets comprise of a hot melt adhesive material that is in a molten state above a particular temperature and gets solidified below a particular temperature. Another exemplary embodiment of the present disclosure is directed towards a planar work material having grooves that are filled with molded-in gaskets, wherein the gaskets are made up of a hot melt adhesive material. The gaskets made of the hot melt adhesive material bond securely with the panels because of inherent adhesive properties, and provide structural stability to the light panels. Another exemplary embodiment of the present disclosure is directed towards the use of a hot melt adhesive material as the molding material for molding-in gaskets within the grooves of a planar work material.

A mould (10) for a tire, comprising two shells (30) that are each intended to mould a lateral sidewall of the tire, a ring of sectors (20) intended to mould a tread of the tire, each sector (20) of the ring of sectors comprising a radially inner face (21) having a moulding lining (22). The mould (10) has microstructures (50) that are designed to fill a clearance between two moulding linings (22) of adjacent sectors (20) and/or between a moulding lining (22) of one sector (20) and a shell (30), when the mould is closed.

A biocompatible and/or food-safe tube assembly (1) is used to connect at least three tube connectors (A, B, C). A first tube section (2) serves to connect two (A, B) of the at least three tube connectors (A, B, C). A sec-ond tube section (3) opens into the first tube section (2) via an orifice (4) in a casing wall (5) of the first tube section (2). An orifice sealing body (8) delimits the orifice (4) to the inner lumen of the first tube section (2) and to the inner lumen of the second tube section (3). The first tube sec-tion 2 and the second tube section 3 are molded onto the orifice sealing body 8. A core (10) is used for this purpose. The result is a biocompatible and/or food-safe tube assembly that avoids manufacturing problems.

The rolling bearing seal includes a core metal and rubber adhered to the core metal by vulcanization. The rubber includes: a seal lip portion having, over the entire circumference in the circumferential direction, a plurality of projections that extend inward in the radial direction from the inner diameter side of the core metal, and slides on a seal sliding surface of an inner ring of a rolling bearing; and an attachment portion that is attached to an outer ring of the rolling bearing. A compression vulcanization molding mold includes a female mold and a male mold. The female mold has a guide portion for positioning the core metal and a rugged shape forming the projections on the seal lip portion. The male mold has an inner-diameter-side burr groove and an outer-diameter-side burr groove and the shape of a radially outermost portion of the inner-diameter-side burr groove is formed in a circle.

A seal configuration, mold and manufacturing process that inhibits undesirable elastomer migration onto critical radially inwardly facing portions of a plastic-lined dynamic sealing lip, for improved high-pressure seal operation.

Embodiments of the present disclosure generally relate to imprint lithography, and more particularly to methods and apparatus for creating a large area imprint without a seam. Methods disclosed herein generally include separating the curing time of the features in a stamp or product from the curing time of the seam and the periphery. The seam and periphery can be cured first or the seam and periphery can be cured last. Additionally, the seam curing operations can be performed on the master, on the stamp, or on the final product.
