Method for manufacturing wireless receiver

A method for manufacturing a wireless receiver, comprising steps of:

• (1) forming a metallic casing having a circumferential wall to define an accommodating space therein, and forming an front opening and a rear opening on both opposite ends of the metallic casing in communication with the accommodating space;
• (2) forming a positioning base via an injection molding process in the accommodating space to join to the circumferential wall of the metallic casing, whereby two side ends of the positioning base are fixed to the circumferential wall, and forming a mounting trough on the positioning base in communication with the accommodating space and the rear opening;
• forming a protruding portion on the positioning base extended outside the rear opening of the metallic casing;
• (3) providing a receiving module, assembling the receiving module in the accommodating space of the metallic casing, and inserting the receiving module into the mounting trough of the positioning base via the rear opening of the metallic casing;
• (4) providing a housing, assembling the housing to the rear opening of the metallic casing, sealing the rear opening by the housing to block the receiving module from sliding out of the rear opening;
• fixing the housing to the protruding portion;
• and
• thereby forming a wireless receiver product.
