The nylon resin is desirably one having a melting point of 200 deg.C or above. The lubricant is selected among graphite, molybdenum disulfide, silicone compounds, fluoro resins, etc. It is desirable that the glass fiber is controlled so that the rate of glass fibers with a weight-average fiber length of 100-400 μm and a fiber length of 60 μm or below may be 10-50 wt.%, based on the total glass fibers, when it is in a state of a melt blend of the nylon resin, especially, in a state subjected to melt kneading once.

Abstract: PROBLEM TO BE SOLVED: To improve the joining strength and reliability of a molding by a method wherein the joining surfaces to be welded are welded after the joining surfaces to be welded are treated with a surface treating agent having a lubricity. SOLUTION: A resin molding is produced by adding additives such as a crystalline nucleating agent such as a talc, a kaolin, an organic phosphor compound or the like, a color protective agent, an antioxidant or the like to one kind or more of a resin selected from the group consisting of a polyamide resin, the major constituent components of which are amino acid, a lactam or a diamine, a dicarboxylic acid, an aromatic polyester resin, a polyphenylene sulfide resin. The surfaces of joining surfaces, through which two or more of these resin moldings are welded together, are treated by applying or spraying a surface treating agent having a lubricity selected from the group consisting of a plasticizer, a lubricant and a lubricating oil and diluting with an organic solvent such as methanol, acetone, methyl ethyl ketone. The surface- treated joining surfaces of resin moldings are joint to each other through the melting by a vibrational welding, a spin welding or the like. Thereby the joining strength and reliability of the joining can be improved.
