Negotiate a solution, seek legal aid, report to relevant departments, etc.

1. Negotiate settlement: You can negotiate with the mold manufacturer or processing plant and ask for compensation for losses or bear corresponding responsibilities. You can clearly express dissatisfaction and make claims for legitimate rights and interests.

2. Seek legal aid: If negotiation fails, you can seek legal aid. Consult a local intellectual property attorney to discuss your rights and available legal options. A lawyer can help evaluate the situation and provide professional legal assistance.

3. Report to relevant departments: You can also report the matter to the local intellectual property management department or relevant industry associations. This can help the department understand the situation and help solve it.
