1. Project Confirmation  

The first thing you need to do before you start customizing your toys is to establish good, frequent, and effective communication with your target manufacturer. Typically, you initiate online business inquiries through the official website of your selected manufacturer. You need to confirm with the manufacturer whether they have the capability for custom products and if their expertise aligns with your customization needs. Once you have verified the capabilities of the targeted manufacturer, you can engage in detailed communication to clarify the specific requirements of your custom project. This includes crucial information such as product design, appearance, features, desired costs, approximate timelines, etc. The purpose of detailed communication is to ensure mutual understanding and agreement on the basic framework of the project.

If you are overseas, contacting the manufacturer via email is often a reliable choice. However, if you find that email correspondence may be delayed due to time zone differences, and the efficiency is too slow, you can opt for online meetings to communicate directly with the manufacturer. Of course, if you have the opportunity to visit the manufacturer in person, that would be excellent. Visiting allows you to tour the factory, observe the production environment, and engage in direct communication with the leadership, gaining insights into their approach and operations. This information will play a crucial role in the subsequent collaboration between you and the manufacturer.

2. Customers Provide Molding Information

In most cases, foreign importers do not have their own injection molds and rely on Chinese Manufacturers to provide mold custom design services. Therefore, you need to provide detailed mold custom information, including design drawings, size requirements, material specifications, etc. This step is crucial to ensure that the manufacturer accurately understands your ideas and requirements and lays the foundation for subsequent design and manufacturing processes. Of course, if you already have your own injection molds, we will tailor the production plan by using your molds.

3. Drawing of Product Images

The manufacturer’s research and development (R&D) department then begins to create specific product drawings based on the information provided by the customer. This step involves translating your concept into a concrete design, laying the foundation for subsequent production. Additionally, at times, the R&D department may produce multiple versions of product drawings to offer customers different design options. This helps ensure that customers can examine the product from various perspectives and make better choices in the final design.

4. Check Product Drawing

After completing the design and illustration of the product drawings, the experienced R&D department and design team meticulously inspect the drawings to ensure there are no overlooked details or errors in the information. This process aids in proactively identifying issues, thereby reducing the workload associated with subsequent corrections.

5. Customers Confirmation of Product Drawing

After the completed product drawings have been meticulously reviewed by the R&D team, the manufacturer will send them to the customer. It is essential for you to conduct a secondary thorough examination, ensuring that the design aligns with your product expectations. If necessary, further modifications and adjustments can be made until you are satisfied.

6. Technical Communication with the Engineering Department

During this stage, the manufacturer’s engineering and technical personnel will engage in detailed technical communication with the customer to ensure a clear understanding of product details and process requirements. Simultaneously, both parties work to comprehend potential challenges that may arise during the manufacturing process. Comprehensive and transparent technical communication is instrumental in addressing potential technical issues, thereby enhancing production efficiency.

7. Injection Molds Designing

Next, based on the mutually confirmed error-free product drawings, the manufacturer’s engineering team begins the mold design process. It is well-known that the production of plastic toys is heavily reliant on precisely designed molds. Therefore, in this step, the manufacturer must meticulously ensure that the final product can be manufactured following the design specifications.

8. Customers Confirmation of Molds Drawing

After the completion of the mold design, the manufacturer will send you the mold drawings for review and final confirmation. Ensure that the mold design aligns with your requirements and expectations. If necessary, you can continue detailed communication with the manufacturer for further modifications and adjustments.

9. Listing Molds Required Materials

After completing the design of the mold drawings, the manufacturer also needs to collaborate with customers to finalize the list of materials required for the mold, including standard and non-standard parts. Both parties will comprehensively consider the quality and availability of different materials, ensuring that the selected materials meet the design requirements of the mold and maintain stable performance throughout the manufacturing process.

10. Purchase of Mold Materials and Standard Parts

The manufacturer will arrange for R&D personnel to procure various materials and standard components required for the molds, as counted in the previous step. This is done to ensure that the quality of the raw materials meets the specified requirements.

11. Customize Non-standard Parts

Certainly, if there is a need for non-standard parts, the manufacturer will specifically customize these non-standard components to meet specific design requirements.

12. Preparation of Production SOP (Standard Operating Procedure)

Next, it’s finally time to prepare for the subsequent production. The manufacturer will formulate a detailed production process, ensuring that each production step adheres to the specified guidelines. Thoughtful and meticulous planning enables your chosen manufacturer to make sure that production can be completed within the negotiated delivery timeframe after consultation with you.

13. Molds Manufacturing Process Control

During mold manufacturing, manufacturers must implement rigorous quality control measures to ensure the molds meet the required standards. Additionally, they must maintain constant communication with you to keep you informed about the progress of the mold production.

14. First Injection Mold Testing

Once the production of the mold for your product is completed, the manufacturer promptly proceeds with the first mold testing, producing the initial sample and sending it to you. Upon receiving the sample, you can naturally conduct inspections, tests, and other activities to provide feedback to the manufacturer.

15. Customers Providing Feedback

As mentioned above, upon receiving the samples, customers need to provide feedback to your supplier regarding the first mold testing samples, including any areas that require adjustment or modification.

16. Modification of Mold

In response, the supplier needs to promptly make corrections and adjustments to the mold based on customer feedback.

17. Second Mold’s Sample Inspection

The modified and adjusted mold undergoes a second round of trial molding, producing new samples that are then sent to the customer once again. The customer reexamines the received samples and provides corresponding feedback.

18. Customers Providing Second-Round Feedback

The customer provides feedback once again, and if necessary, adjustments to the mold are made.

19. Modification of Mold for the Second Time

The manufacturer makes further adjustments and modifications to the mold based on customer feedback.

20. Final Mold’s Sample Inspection 

Conduct the final trial molding, produce the ultimate version of the sample, and send it to the customer. The customer conducts the final inspection and confirmation.

21. Molds Confirmation

The customer confirms that the mold meets the requirements and formally accepts the mold.

22. Package Design and Sampling

After confirming the product without any issues, you will need to discuss and design suitable packaging for your product with the manufacturer. Once you provide the manufacturer with your packaging ideas and templates, they will customize packaging samples for your review and confirmation.

23. Sample Confirmation Before Mass Production

Finally, in the last step before mass production, you have thoroughly inspected and confirmed the samples of the product and its packaging provided by the manufacturer. Once you ensure that the final product and its packaging meet your expectations, you will provide the manufacturer with the final notification.

24. Mass Production

After confirming everything is error-free, large-scale production commences.

25. Shipping

Upon completion of production, the products are arranged for shipping to ensure timely delivery to the customers.

Through these 25 essential steps, I believe you can successfully customize toys in China that meet your requirements and import them into your target market and country. Clearly, close cooperation between manufacturers and customers, along with effective communication, is crucial throughout the entire process to ensure the quality and design of the final product meet the expectations of both parties.
