I'm looking for pricing information on your semi-automatic bagging machines suitable for field operations. We're interested in understanding the features, specifications, and any customization options you offer. It would be great to know if there are different models available and the price variations between them. Additionally, if you could provide details on the lead time for ordering, minimum order quantities, and any warranty or after-sales support that comes with the machine, that would be really helpful. We're particularly focused on efficiency and reliability, so any insights into performance metrics would also be appreciated. Looking forward to your prompt response!
