Injection molding device and injection method thereof
Provided is an injection molding device, including an injection port arranged on an upper mold base; an upper mold arranged in the upper mold base, wherein at least one ejection port, a gasket groove and a gasket are provided and the ejection portion is connected to the injection port; a lower mold base operatively aligned with or separated from the upper mold base and provided with at least one gas passage for the gas to enter or exit; and a lower mold disposed on the lower mold base. The lower mold base is aligned with or separated from the upper mold base, the lower mold is provided with a mold cavity and at least one shaped air path is provided to connect the mold cavity with the gas passage. The lower mold is a porous material and has a plurality of pores. Gas is pre-injected into the mold cavity through the gas passage and at least one air path to maintain a preset pressure inside the mold cavity. Gas is spewed out through the plurality of pores, thereby causing a finished product to exit the mold cavity. In addition, the present disclosure also provides an injection molding method.
Lining Element, and Process for Manufacturing a Lining Element
A lining element for use in a vehicle in order to cover an airbag includes a dimensionally stable backing layer with a first predetermined breaking region which is delimited from a surrounding region and/or from a second predetermined breaking region by at least one predetermined breaking line, where a plurality of regularly spaced predetermined breaking points are disposed along the predetermined breaking line.

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.

Foam molding device
A foam molding device includes an outer mold unit and an inner mold unit. The outer mold unit includes an outer upper mold and an outer lower mold that cooperatively define a receiving space. The inner mold unit is detachably disposed within the receiving space, and includes an inner upper mold and an inner lower mold. The inner upper mold and the inner lower mold cooperatively define a foaming space adapted for foam molding a foam material into a foamed object.
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.
FOOTWEAR COMPONENT MANUFACTURING SYSTEM
A system including an injector, a press, and a robotic conveyance is used to form a physically foamed article of footwear component from a single-phase solution of a polymeric composition and a supercritical fluid. The parameters and features of the system are configured for the formation of the footwear component in an automated manner with enhanced throughput by the system.
