一体成形の加工法としては、種々のものを用いることができる。
例えば、ブロー成形やプレス成形が可能であるが、これに限るものではない。
ブロー成形は、均一な板厚で一体成形するのに適し、また、金型が一方のみなので低コストの利点がある。
また、プレス成形は、角部が薄くなるおそれがあるが、部位に応じて板厚を変化させることが可能になる。 Various processing methods can be used for the integral molding.
For example, blow molding or press molding is possible, but the present invention is not limited to this.
Blow molding is suitable for integrally molding with a uniform plate thickness, and has an advantage of low cost because there is only one mold.
In press molding, the corner portion may be thinned, but the plate thickness can be changed depending on the part.
