Communicate with customers about the technical requirements and parameters of customized products in the early stage, determine the quantity of required products, evaluate and negotiate the production cycle. Try to cooperate with customers to complete the production cycle within the time required by customers.

1. Make a production process flow chart according to the requirements of customers.

2. After both parties determine the drawings, sign a contract and pay a deposit.

3. Since the products are non-standard customization, the acceptance standards in different regions are different, and the contract signing, acceptance and delivery date are the criteria.
