METHOD FOR MANUFACTURING WIRING BOARD, WIRING BOARD, METHOD FOR MANUFACTURING MOLDED OBJECT, MOLDED OBJECT
A method for manufacturing a wiring board includes: disposing a first resist material on a substrate; forming a first resist layer by curing the first resist material; forming a resin layer on a release film; forming a conductor portion on the resin layer; covering the conductor portion by disposing a second resist material on the resin layer; forming a second resist layer by curing the second resist material; bringing the first resist layer into contact with the second resist layer, and thereafter bonding the first resist layer and the second resist layer by thermocompression bonding; and releasing the release film from the resin layer.
Method for forming a stress-free multilayer PVC sheet material
A method for forming a multilayer plastic sheet material (1) for floor and/or wall panels, wherein a first polymer mass comprising a rigid PVC is melted under pressure and is passed through an extruder head at a specified discharge rate in the form of a plastic strand in sheet form that is provided with one or more layers so that a multilayer plastic strand is formed, which is passed to two or more rolls of a finishing stand, which processes the multilayer plastic strand into a sheet of defined thickness, which is then led away via a transport device to a sawing device to be cut to the desired length, wherein, after the plastic strand in sheet form leaves the extruder head, it is first passed between a top roll and a bottom roll of a roughing stand, wherein the speed of the rolls of the finishing stand and the rolls of the roughing stand is synchronized with the discharge rate of the plastic strand in sheet form from the extruder head, so that said plastic strand is processed without stress.
Plastic floorboard processing technology using digital printing
A plastic floor board processing technology using digital printing, aiming to solve the problem relating to the high production cost, comprising the steps of: preparing a base material; blending the base material; extruding the blended base material into a mold to form a stone-plastic base material; adjusting a gap between a surface embossing roll and a bottom embossing roll to enable the stone-plastic base material to pass through the gap; generating embossing patterns and positioning marks at equal intervals on a surface of the stone-plastic base material; cooling the stone-plastic base material; cutting the stone-plastic base material into plastic floorboards; using a digital printer to print the plastic floorboards. According to the present disclosure, patterns are directly printed on the surface of the stone-plastic base material, which avoids the processes of arranging a color film and a wear layer, lowers the production cost and improves the production efficiency.

SHEET PRODUCTION LINE
A sheet production line comprises: a calender for laminating and calendaring a sheet blank; a first conveying mechanism arranged at a discharge end of the calender and used for carrying and conveying a semi-finished sheet product output from the calender, where the first conveying mechanism is a traction conveying mechanism; a section cutting mechanism arranged behind the discharge end of the calender in a traveling direction of the semi-finished sheet product; and a second conveying mechanism arranged at a discharge end of the section cutting mechanism in a traveling direction of the sheet sections, where the second conveying mechanism is a non-traction conveying mechanism.
IN-LINE LAMINATION PROCESS FOR PRODUCING THERMOPLASTIC COMPOSITE PANELS WITH EMBOSSED FILM LAYERS
In-line systems and in-line methods are described that can be used to provide lightweight reinforced thermoplastic composite articles that include a textured or an embossed film layer. The textured or embossed film layer can provide one or more of water resistance, flame retardancy, a desired surface roughness, enhanced peel strength, enhanced acoustic absorption or other desired properties. The lightweight reinforced thermoplastic composite articles that include a textured or an embossed film layer can be used in building applications, in recreational vehicle applications and in other applications as desired.
Continuous mixing for highly viscous materials
A method includes feeding a heated polymer additive at a first temperature into a continuous mixer at a first feed rate. The method includes feeding a heated abrasive solid material at a second temperature into the continuous mixer at a second feed rate. The heated abrasive solid material and the heated polymer additive are mixed in the continuous mixer to form a first mixture.

Engineering reversible elasticity in ductile or brittle thin films and products resulting from said engineering
The present disclosure relates to how to engineer reversible elasticity in thin films and/or layers and/or substrates, using a repeated Y-shaped motif, which is cut out through the film and/or layer and/or substrate. As an example, using a 75 μm thick polyimide (PI) foil, macroscopic dog-bone shaped structures with a range of geometrical parameters of the Y shape have been prepared according to an embodiment of the present disclosure. The tensile strain response of the film at its point of fracture was then recorded. The structures were also confirmed using finite element modeling. Upon stretching, the PI ligaments locally deflect out of plane, allowing the foil to macroscopically stretch.
Transfer film and membrane coverings for panel products
A membrane covered panel and a membrane covered panel production method are provided wherein an elastomeric membrane, and preferably, an aqueous elastomeric resin-based membrane, is applied to a finished panel construct, prior to pressing of the membrane covered panel. The method is used to produce panels which can be used in the production of flooring materials, wall panels, furniture, countertops, and the like. The membrane is applied to a transfer film, which transfer film can be removed at any time prior to, or after the pressing operation. The panels produced have a durable but elastic surface which can protect the surfaces of the panel construct. The elastomeric covering on the panel construct also preferably provides a surface which is abrasion resistant, and provides better acoustical properties while providing a soft touch haptic surface.
