Title:
METHOD FOR INSERT MOLDING AND INSERT-MOLDED PART
Document Type and Number:
Japanese Patent JP3877837
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve bonding between an insert and resin of an insert-molded part even when crystalline thermoplastic resin (specially, liquid crystalline polymer) is used.
SOLUTION: In a method for insert-molding thermoplastic resin, insert molding is performed by reducing thickness of resin base 1 near a metal bar (an insert) 2 for forming a thin part 3. In this method, it is effective to reduce thickness of the resin base near the insert (the thin part) by 20% or more. The thermoplastic resin includes crystalline thermoplastic resin, for example, liquid crystalline polymer, etc.
