The intake manifold is divided into an upper section, a middle section and a lower suction. Injection forming is adopted. The upper section and the middle section are welded through an arc-shaped surface, and the middle section and the lower section are welded through planes. Firstly, welding of the upper section and the middle section is conducted on a vibration friction welding machine, and then a welded combined body of the upper section and the middle section is welded to the lower section so as to achieve assembly. The welding vibration frequency is 230-240 Hz, the amplitude is smaller than or equal to 1.2 mm, the welding pressure is 1000-1200 Kg.f, welding time is 20 sec and weld penetration is 1.5-1.8 mm. Welds are composed of multiple sections. The included angles alpha between all the welding sections are smaller than or equal to 60 degrees, the section lengths L are smaller than or equal to 30 mm, and the sectional plane angles beta between contact friction surfaces and vibration axes in the range of weld contour surfaces are smaller than or equal to eight degrees. The welds are fused through vibration friction heat, and then post-welding pressure maintaining is conducted, so that stable welding joints are obtained through infiltration diffusion of materials on the two sides of the welds. The vibration friction welding process is especially suitable for connection of parts made from non-metallic materials such as a long glass fiber reinforced thermoplastic composite material.
