Estimating the term…
The object of the invention is, in integrating two or more types of resin materials having different compositions or tones in a mold, thus molding a multi-color, multi-material molded article, to increase the strength of the bonding surfaces of the resins. To achieve this object, this invention provides an injection molding method of injecting two or more types of resin materials having different compositions or tones into a mold, thus producing a molded article in which the two or more types of resin materials are bonded. Convexo-concave shapes are formed on the bonding portions of the two or more types of resin materials.
An injection molding method of injecting not less than two types of resin materials having different compositions or tones into a mold, thus producing a molded article in which said at least two types of resin materials are bonded, wherein
An injection molding method of injecting not less than two types of resin materials having different compositions or tones into a mold, thus producing a molded article in which said at least two types of resin materials are bonded, wherein
An injection molding method of producing a molded article in which not less than two types of resin materials having different compositions or tones are bonded, comprising:
An injection molding method of producing a molded article in which not less than two types of resin materials having different compositions or tones are bonded, comprising:
An injection molding method of injecting first and second resin materials having different compositions or tones into a mold, thus producing a molded article in which the first and second resin materials are bonded, comprising:
An injection molding method of injecting first and second resin materials having different compositions or tones into a mold, thus producing a molded article in which the first and second resin materials are bonded, comprising:
An injection mold for producing a molded article in which first and second resin materials having different compositions or tones are bonded, comprising:
An injection mold for producing a molded article in which first and second resin materials having different compositions or tones are bonded, comprising:
A resin-molded article in which not less than two types of resin materials having different compositions or tones are bonded, wherein bonding portions of the not less than two types of resin materials are shaped in convexo-concave.
A resin-molded article in which not less than two types of resin materials having different compositions or tones are bonded, wherein bonding portions of the not less than two types of resin materials are shaped overlappingly in a direction of thickness thereof.
An insert resin product which is to be integrated in a cavity of a mold with another resin material having a different composition or tone, wherein a bonding portion with another resin material is shaped in convexo-concave.
An insert resin product which is to be integrated with another resin material having a different composition or tone in a cavity of a mold, wherein a bonding portion of the insert resin product is shaped overlappingly in a direction of thickness with respect to another resin material.
A method of performing injection molding to produce a molded article by using a plurality of resin materials, wherein
A toner container having a tab which is molded from a plurality of resin materials having different injection temperatures, wherein
