PROCESS FOR PRODUCING A STRUCTURED AND OPTIONALLY COATED ARTICLE AND ARTICLE OBTAINED FROM SAID PROCESS
Described herein is a process for preparing a molded article including at least one structured surface, said process including applying a composition, preferably a foam material, into a mold having at least one structured inner surface and curing said composition to provide the molded structured article. The inner surfaces of the mold can be coated with a coating composition to obtain molded structured articles further including a flexible and durable coating layer. The present invention also relates to a structured molded article, preferably a shoe sole, which is obtained by the process.
INJECTION MOLDED PRODUCT
An injection molded product includes a main body portion having a design surface and an opposite surface; and a projecting portion provided at a peripheral edge portion of the main body portion, and projecting out toward a side opposite from the design surface in a thickness direction of the main body portion, wherein a thickness A of the main body portion and a thickness B of the projecting portion satisfy a relationship of A≥B.
Foam article with enhanced properties
A foam article, such as a cushioning element for an article of footwear, apparel or sporting equipment is provided that comprises a foam component, such as a midsole, having a number of beneficial physical characteristics. The cushioning element is a low-density foamed component with a surface skin that encases the remaining foam volume. The cushioning element has a number of foam volumes, arranged to achieve a more consistent foam component. Additionally, the cushioning element includes a series of concentric ridges extending radially outwardly from injection gate vestige locations, and a number of striation bands near the perimeter of the cushioning element. The location of the gate vestiges can be beneficially arranged to produce intersecting flow boundaries that are located away from key strain areas of the cushioning element. The cushioning element is more environmentally-friendly, requiring less energy to produce while still providing acceptable energy return and low density.
MOLDING DEVICE AND INJECTION MOLDING METHOD THEREOF
A molding device and an injection molding method thereof are provided. The molding device includes a first mold, a second mold and a sealing ring. The first mold includes a first body and at least one slide. The at least one slide is movably and detachably disposed on the first body, and has an undercut. The injection molding method includes operations of: engaging the first mold with the second mold of the molding device; filling a mold cavity defined by the first mold and the second mold with a gas, wherein the gas is blocked by the sealing ring disposed between the first mold and the second mold; injecting a molding material into the mold cavity; and opening the first mold and the second mold of the molding device.
METHOD FOR PRODUCING FOAMED FLAT MOLDINGS AND MOLD FOR CARRYING OUT SAID METHOD
The invention relates to a method for the production of foamed areal polyurethane(PUR)/polyisocyanurate(PIR) moldings, where a polyurethane/polyisocyanurate reaction mixture is injected into a mold that is under elevated pressure and then a depressurization takes place, and the foaming process is thus induced, and after the reaction the molding is demolded, and to a mold for carrying out the method.
SEAT PAD MANUFACTURING METHOD
A seat pad manufacturing method is provided. The method includes disposing a sheet member inside a foaming mold for shaping a seat pad, then injecting a foaming resin material into the foaming mold and foaming a resin foamed body through mold clamping, and demolding the resin foamed body in a state in which the sheet member is buried in the resin foamed body. Both end parts of the sheet member in the right-left direction and both end parts of the sheet member in the extending direction are each temporarily fastened to the surface of the mold through a fastener. The foaming resin material is injected into a space between the mold surface and the sheet member. A central part of the sheet member deforms into a shape curved in a convex shape as the sheet member is pressed upward through expansion of the foaming resin material.
SEALING ELEMENT
A sealing element for a molding machine comprises a base body with an inner receptacle wherein the base body is provided with a venting duct to connect an inner receptacle of the sealing element with an outer surface thereof.
INJECTION MOLDING SYSTEM AND METHOD
An injection molding method includes providing a molding device including a first mold, a second mold over the first mold and a first mold cavity defined by the first mold and the second mold; injecting a first material into the first mold cavity; forming a first layer from the first material; replacing the second mold by a third mold, injecting a second material into a second mold cavity defined by the first mold and the third mold; and forming a second layer from the second material, wherein the second layer at least partially contacts the first layer. The first material is same as the second material.
METHOD FOR PREPARING A RIGID POLYURETHANE FOAM
The present invention relates to a method for preparing a rigid polyurethane foam using a non-continuous production process, the rigid polyurethane foam prepared therefrom, and use thereof.
Seating assembly with ventilation
A vehicle seating assembly includes a first part, a second part with a second foam part, and a barrier with a permeable portion and a non-permeable portion. The vehicle seating assembly also includes an air passageway extending through the first part, the second foam part, and the permeable portion of the barrier and an air mover fluidly coupled to the air passageway for moving air through the air passageway.
