Communicate with customers about product parameter requirements and uses, and determine the final plan

1. Make samples according to customer requirements. Some products require molds, and the mold costs need to be borne by customers. (If the number of orders reaches a certain amount, we can return the corresponding mold costs).

2. After both parties determine the drawings, make samples.

3. Test whether the samples meet the requirements. If they meet the requirements, sign a contract and pay a deposit.

4. Mass production.
