FAQ

What's Your Delivery Time?

– Normally 25 days.

What Is The Payment Term?

– T/T (30% advance payment, and 70% balance paid one week before shipment)
– L/C (100% L/C at sight). This should be negotiated first.

What Is The MOQ Or OEM?

– MOQ: 1 set. We accept OEM.

How Do You Guarantee The Quality?

– We guarantee you the quality of our machine (e.g. processing speed and working performance will be the same as the data of the sample machine as well as your requirements). The contract will contain detailed technical data.

– We always arrange final testing of operation before shipment. The machine will be tested for a few days, and then use customer’s materials to test its performance. After we confirmed there are no problems with the machine, then the shipments will be arranged.

– We provide the machine with a 5-year warranty. Flexible extended warranties can be offered as agreed.

What kind of packing do you use for your machines?

– As our machines are large-scale equipment, they are usually directly loaded into containers and then fixed by steel wires, so that when the freighter is sailing on the sea, the machines will not hit the inside of containers because of the ship’s swing, so as to ensure that the machines are intact. In addition to the machine you ordered, the container will not put any other items.

How does your company provide after-sales service?

– For small problems in the process of using the machine, we will arrange mechanical engineers to help you solve them remotely, one-to-one guidance, such as sending text instructions or videos to teach you how to solve the problem. If the parts need to be replaced are within the warranty period, we will send them to you free of charge. Of course, you can also buy them locally (if you can buy them), which can save more time. For more serious problems, if the way of remote guidance is not working, we will arrange engineers to provide on-site service. For regions with agents, we will contact agents directly to provide services.

Does your company provide training?

– Yes, you can arrange relevant personnel to our company for on-site study, and we will arrange a special person for one-to-one guidance. If it is not convenient for you to come to our company, we can provide remote training.

How do you charge the ocean freight?

– As for the ocean freight, it is usually charged by the freight forwarder. You can use our freight forwarder to arrange the delivery, or you can use your own freight forwarder.

Will your company provide relevant paper materials?

– Of course. Usually follow the machine delivery also includes a variety of manuals, operating instructions, precautions, circuit diagrams, hydraulic diagrams, etc.

How to ensure that the machine I ordered is suitable for me?

Before you place an order, our salesman will have a detailed and in-depth communication with you, determine every detail of your requirements, and finally provide the corresponding machine configuration according to your specific needs. We never recommend you to buy more expensive machines just to sell them. Expensive ones may not be suitable for you.
