An apparatus for extruding a jacket and/or insulative material onto an extruded product with one or more longitudinal stripes incorporated onto the surface of said extruded product comprising a body, a primary feed conduit for conveying a primary extrusion material, a striping die, a secondary feed conduit for conveying a secondary extrusion material, a striping die adapter, a striping feed conduit extending through the striping die adapter for conveying striping extrusion material. The striping die adapter may also include a thermocouple for maintaining the viscosity of the striping extrusion material and a thermocouple for monitoring the temperature of said striping die adapter. The striping die includes one or more striping extrusion outlets for conveying striping extrusion material onto the extruded product. The striping die may also include a wishbone-shaped trough for delivering equal amounts of striping extrusion material to said extrusion outlets for extrusion onto the product.

Disclosed herein is a die assembly comprising a first attachment block having a passage, an inlet port and an exit port; where the passage is operative to transport a molten material from the inlet port to the outlet port; a die; and a conduit; where the conduit comprises a passage that is operative to transport the molten material from the first attachment block to an entry port of the die; where the die comprises a first outer tube; and an extrusion pin that comprises a post and fins; where the extrusion pin is located in the first outer tube using the fins and where the post extends from the fins in a direction away from the entry port of the die; and where the post comprises one or more passages; where at least of these passages open to the atmosphere to provide for pressure equalization; and a travelling template; the template being operative to contact an extrudate that emanates from the die and to transfer a texture to a surface of the extrudate by virtue of pressure applied by a guide tube to the extrudate via the travelling template.

In a process for manufacturing a catalytic converter component, a ceramic unit is used that has been prepared by extruding green ceramic product through a die to form an extrusion having a honeycomb substrate structure in which tubular passages extend along the extrusion, the passages bounded by walls dividing adjacent passages from one another. The unit is obtained by cutting off a length of the extrusion and curing and firing it. The process further comprises flowing insulation material from one end of the unit into selected ones of the elongate passages, vaporizing a moisture content of the insulation material to form pores and curing the insulation material by using microwave irradiation to solidify the pores. The passages are selected so that the cured insulation material forms an internal thermal insulating barrier between a core zone of the unit and a radially outer zone of the unit.

Subject matter of the present invention is a method of applying coating layers (9) to a substrate (1, 11, 21, 31), wherein the substrate (1, 11, 21, 31) is drawn through a coating chamber (2) containing a pressurized coating agent (3) being liquefied or softened by means of a thermal exposure, wherein the substrate (1, 11, 21, 31) is drawn through a drawing tool (8), wherein the coating agent (3) serves as a lubricant between the drawing tool (8) and a surface of the substrate (8) and wherein at the same time the coating layer (9) is applied to the surface of the substrate (8). Subject matter of the invention is also a corresponding apparatus for applying a coating layer (9) to a substrate (1, 11, 21, 31). By means of the invention coating layers can be applied to a substrate in an efficient and economical way.

A liquefier tube for an additive manufacturing system, the liquefier tube including a body provided with a feed channel including a feeding portion having a first diameter, an outlet portion having a second diameter, the first diameter being larger than the second diameter, a transitional portion interconnecting the feeding portion and the outlet portion. The transitional portion has a monotonically decreasing third diameter from the feeding portion to the outlet portion and the third diameter as function of a longitudinal position of the feed channel in the transitional portion between the feeding portion and the outlet portion and at a transition between the transitional portion and the outlet portion is differentiable. Methods of manufacturing the liquefier tube.

Described herein are portable apparatuses and methods of creating fibers, such as microfibers and nanofibers. The methods discussed herein employ centrifugal forces to transform material into fibers. Portable apparatuses that may be used to create fibers are described.

A slot die assembly for dispensing a fluid onto an article includes an adapter body, a shim package and a die plate. The adapter body includes an adapter conduit configured to receive a fluid. The shim package includes a plurality of shim plates having a shim conduit disposed in fluid communication with the adapter conduit and configured to receive the fluid from the adapter conduit. The shim package further includes a connecting conduit disposed in fluid communication with the shim conduit, a reservoir disposed in fluid communication with the connecting conduit, and a slot disposed in fluid communication with the reservoir. The slot is configured to dispense the fluid onto an article. The die plate is disposed in abutting relationship to the shim package.

An extrusion die with adjustable land channel can be formed of a die body that includes a first die body portion and a second die body portion, a first lip body, a second lip body, and a land channel body. The extrusion die can have a flow channel that includes a land channel terminating in an outlet orifice. The flow channel may be bound on one side by the first die body portion, the land channel body, and the first lip body. The flow channel may be bound on an opposite side by the second die body portion and the second lip body. In some examples, the length of the land channel is adjustable by configuring the land channel body and/or first lip body to move across the width of the flow channel.
