1. **Understand customer needs**: Discuss the usage and mechanical performance requirements of parts with customers in depth to ensure a comprehensive understanding of customer needs and the mechanical properties that parts need to meet.

2. **Material research and design suggestions**: Assist customers in research and design, provide targeted structural modification suggestions, and provide material selection suggestions.

3. **Process selection and quotation**: According to the annual usage and mechanical characteristics of the casting, select the most cost-effective casting process for customers and provide detailed quotations.

4. **Mold development**: Customize metal casting molds, start mold development after confirming the process and quotation, ensure the precise manufacturing of parts, and select the best mold materials to ensure their service life.

5. **Production plan**: Develop a production plan based on customer delivery requirements to meet customer needs to the greatest extent.

6. **Sample production**: Usually before mass production, the foundry will mail samples for testing to ensure that the quality of the castings meets customer expectations.

7. **Sample testing**: Perform various tests, including but not limited to material testing, coordinate measurement, X-ray testing, magnetic particle inspection and sampling testing to ensure that the parts meet high standards.

8. **Reporting terms**: Provide comprehensive test reports to ensure transparency and credibility of the partnership.

9. **Sample transportation and mass production**: The foundry delivers samples to customers. After qualified testing by customers, mass production begins to ensure stable quality.

10. **Delivery service**: Provide door-to-door comprehensive transportation services to create the most convenient conditions for customers and ensure on-time delivery.

11. **Order reception**: Customers submit order requirements and related technical requirements to the mold company, the mold company receives the order, and confirms and communicates with customers to ensure the accuracy and completeness of the order requirements.

12. **Scheme design**: The mold company's designers formulate mold design plans based on customer needs and technical requirements, and conduct feasibility assessments, including technical difficulty analysis and risk assessments.

13. **Manufacturing**: The mold company manufactures molds according to the design plan, including structural design, material selection and process requirements.

14. **Quality control**: During the mold production process, strict quality control is carried out to ensure that mold manufacturing meets product requirements.

15. **Mold testing and inspection**: The processed mold is matched with the product prototype, and plastic or metal is injected into the mold through injection molding to confirm the accuracy and stability of the mold.

16. **Delivery and after-sales service**: After strict inspection and testing, the mold is successfully manufactured and delivered to the customer, and corresponding after-sales services are provided, including mold installation, commissioning, repair and maintenance.
