Injection foam molding method
In an injection foam molding method, a relationship between a flow front moving speed (cm/s) of a foamed resin material in an injection step of injecting the foamed resin material into a cavity and amount of gas generated per 1 g of a resin material (ml/g) is defined as follows: the amount of gas generated per 1 g of the resin material is 0.36 ml/g or more; and the flow front moving speed (cm/s) is 75×the amount of gas generated per 1 g of the resin material (ml/g)−35 or more and 12 cm/s or more.
BUILDING PANELS HAVING SIMULATED WOOD GRAIN AND METHODS OF MAKING THE SAME
Building panels and methods of making the same are disclosed herein. In one embodiment, a method of injection molding a building panel includes co-mingling a first material and a second material in a molten material, where the second material includes a color that contrasts with the first material. The method also includes injecting the molten material into a cavity of an injection mold, modifying a flow front of the molten material as the molten material flows in the cavity, and cooling the molten material to form a solidified building panel.
INSERT-MOLDED ARTICLE AND METHOD FOR PRODUCING THE SAME
A metal component has a shape including a flat plate-shaped part, and the flat plate-shaped part has a through-hole formed therein. A resin component has a shape including a covering part that covers a surface of the flat plate-shaped part, and the covering part has a surface in which a gate mark is present. The through-hole formed in the flat plate-shaped part of the metal component is located opposite to the gate mark. The resin component has a filler part with which the through-hole is filled.
Injection molding a device such as a cable holder with an integrated wireless tagging foil
The disclosure relates to a method for injection-molding a device, in particular a cable tie, with an integrated wireless tag, comprising the method steps of a) putting a tagging foil with two main surfaces which are separated by an edge, into a mold cavity of an open mold, where the tagging foil is held in place by a supporting device; b) closing the mold; c) injecting an injection material into the mold cavity parts adjoining the two main surfaces of the tagging foil simultaneously and symmetrically with respect to a main extension plane of the tagging foil which is parallel to the two main surfaces of the tagging foil so as to simplify and speed up the manufacturing process of a device with an integrated wireless tag or label. The disclosure furthermore relates to a corresponding molding device as well as a corresponding device with an integrated wireless tag.
SEMICONDUCTOR MODULE CASE AND METHOD FOR PRODUCING SEMICONDUCTOR MODULE CASE
A semiconductor module case formed by injection molding into a box shape using a mold open on a bottom thereof, includes an external terminal disposed on a top face or a side face of the case, the external terminal penetrating through the case from an inside to an outside thereof and being electrically connectable to a semiconductor element inside of the case, and a single first gate for a resin to enter the case. The case has a rectangular shape in a plan view of the case and has first and second short sides and first and second long sides, and the first gate is disposed at a side face of the first short side and has a flat surface area having a first width that extends along the first short side in a width direction of the case.
Resin molded article and manufacturing method therefor
A resin molded article is equipped with a laminated body in which a core material layer, a cushion layer, and a skin layer are included and laminated. In this configuration, a lowermost layer and a peripheral edge portion of the laminated body are covered by a resin covering layer, and only the upper surface of the skin layer is exposed and serves as a design surface. Moreover, the peripheral edge portion of the laminated body is embedded in an interior part of the resin covering layer.
METHOD OF MAKING A METAL INJECTION MOLDED AMMUNITION CARTRIDGE
The present invention provides a method of making a metal injection molded ammunition cartridge comprising the steps of: providing an ammunition cartridge mold comprising a bottom portion having a primer recess extending into the bottom portion adapted to receive a primer, a flash hole positioned in the primer recess through the bottom surface; side walls extending from the bottom portion to a nose end aperture, wherein a propellant chamber is formed between the nose end aperture and the bottom surface; injecting a metal composition into the ammunition cartridge mold to form a metal injection molded ammunition cartridge; and removing the metal injection molded ammunition cartridge from the ammunition cartridge mold.
Method of making building panels having simulated wood grain
Building panels and methods of making the same are disclosed herein. In one embodiment, a method of injection molding a building panel includes co-mingling a first material and a second material in a molten material, where the second material includes a color that contrasts with the first material.
