Technical Data

Spare Parts Planning

For machines that run frequently, common models and key automation parts should be recorded in a spare parts list. Keeping suitable replacement parts in stock can shorten downtime when a fault occurs and reduce the time spent confirming model numbers during urgent maintenance. Stock records should include brand, model, specification and equipment position so the correct item can be found quickly.

Installation Reminder

Before installation, the machine should be placed in a safe condition according to site procedure, including disconnecting power, air supply or pressure source when required. During fitting, pay attention to interface direction, fixed position, seal placement and connection tightness. After installation, start with low-speed, low-pressure or no-load testing before returning the equipment to normal operation.

We support several common payment methods for different purchasing situations. International orders can be paid in USD by T/T, PayPal or other agreed methods depending on order amount and shipment arrangement. For RMB payments in mainland China, Alipay QR and WeChat Pay QR can also be arranged.
