Horizontal one is most common, easier for repairing, more stable due to its low center of gravity, easier for fully automatic production, etc. As for vertical one, its advantages are less occupation area, easier for loading mould, etc. For machine below 60ton, you can prefer vertical one, when you require bigger tonnage of injection molding machine, you would better take horizontal one.
