This machine needs to undergo a 24-hour pressure test and sealing test before leaving the factory to verify the bearing capacity of the oil cylinder plunger and ensure no leakage issues. Our engineers can customize equipment according to customer needs and provide design drawings for confirmation to ensure compliance with expectations. We are always committed to reducing costs for our customers. During the production process, we regularly take photos and share them with customers for real-time tracking of production progress. After delivery, we will promptly provide relevant documents such as packing lists, commercial invoices, bills of lading, etc. In addition, we can provide basic English DWG files, installation guides, user manuals, maintenance manuals, and part drawings for free to support customers' use and maintenance.
