Generally speaking, the mechanical parts of the envelope machine have a long service life and are less likely to be replaced frequently. Therefore, after a large investment in the purchase of the envelope machine, the purchase cost of the later parts often does not attract the attention of the printing factory. However, from the perspective of long-term use cost, the normal loss and replacement cost of spare parts after purchasing the machine also needs to be considered before purchasing the machine.
In terms of price, the spare parts of imported envelope machines are often more expensive, compared to the relatively low cost of spare parts for domestic and Taiwanese brands of envelope machines. As far as the supply of spare parts is concerned, the supply speed of spare parts for imported envelope machines is generally slow. When the production of the printing factory is urgent, it is likely that the supply is not timely and the production is delayed. Domestic and Taiwanese envelope machines, on the other hand, can provide better supply services due to their "geographical advantage".
