(3) extrusion process assembly room temperature is higher, and production work environment is poor, easily occurs production safety problem, and a lot of enterpriser and workman are unwilling to be engaged in the industry;
(4) aluminium alloy oscillator die cast needs the die-cut mouth of a river, polishing batch cutting edge of a knife or a sword, the operations such as polishing, and then electroplates, and the comparatively complicated manufacturing cost of technique is also higher.
(5) antenna oscillator majority is all matrix type structural design, all easily causes deformation of products at die cast, the die-cut mouth of a river, polishing, glossing, and dimensional accuracy is difficult to ensure.
(6) die-casting forming die complex structure, internal mold is all that high-temperature steel material is heat-treated, and die cost is higher but useful life is shorter.
Therefore, existing antenna oscillator structure haves much room for improvement.
