Compared to other casting manufacturers, we consistently work closely with our clients to fulfill their needs and respond promptly to any questions they may have during the new product development process. Here is the typical new product development process at Y&J:
1. The client sends Y&J the drawings together with the technical requirements.
2. Y&J makes a quotation in 2-5 days and sends it to the customer.
3. Upon receiving the client's sample order, Y&J will issue a proforma invoice for a 50% down payment on patterns.
4. Y&J starts to make patterns upon receiving the down payment. Typically, the sample production cycle lasts approximately 8-10 weeks.
5. The samples will be sent to the client for approval. Sometimes the client will skip this process and approve the samples based on the inspection reports Y&J submitted.
6. After the samples are approved, the client pays the remaining 50% of the patterns and the sample fee. The sample development process is completed.
