Problems solved by technology

This process is an effective method, but since molding is performed with a low-temperature metal mold, in order to improve the physical properties and crystallinity of PAS resin, a heat treatment process is required after molding, and there is a problem that the process is complicated

Abstract

The present invention provided an insert molded product excellent in high and low temperature impact characteristics and reduced in the occurring amount of a mold deposit at the time of molding. This insert molded product is constituted by the insert molding of a resin composition, which is obtained by compounding 5-200 pts.wt. of a fibrous reinforcing material (B) having a flat cross-sectional shape wherein the ratio of the long diameter (the longest straight line distance of a cross section) and short diameter (the longest straight line distance in the direction right-angled to the long diameter) of a cross section right-angled to a length direction is 1.3-10 and 1-25 pts.wt. of a thermoplastic elastomer (C) with 100 pts.wt. of a polyarylene sulfide resin (A), and a metal or an inorganic solid.

Description

technical field [0001] The present invention relates to an insert molded product obtained by insert molding a specific resin composition and a metal or an inorganic solid, in particular to an insert molded product with improved high and low temperature impact properties. Background technique [0002] The insert molding method is a molding method that effectively utilizes the properties of the resin and the properties of the metal or inorganic solid (hereinafter referred to as metal, etc.) blanks to embed metals in the resin. It is used in automotive parts, electrical and electronic components, and OA machine parts It has been used in a wide range of fields, and is now one of the general forming methods. [0003] However, resins and metals have very different expansion or contraction rates (so-called linear expansion coefficients) due to temperature changes, so molded products with thin resin parts or parts with large changes in wall thickness and metals have Molded products...
