5. Responsibilities

5.1 Procurement Department:

Responsible for the procurement of materials required for mold trials.

5.2 Quality Department:

Responsible for pre-trial inspections and post-trial inspection of molded parts.

5.3 Assembly Department:

  • Responsible for implementing the preparation, modification, and self-inspection of trial molds.
  • Responsible for the improvement and packaging of molds that pass the trial.

5.4 Project Department:

  • Responsible for centralized management of mold trial.
  • Responsible for participation and documentation throughout the mold trial process.
  • Responsible for inspecting the dimensions and assembly of trial mold products after mold trials.
  • Responsible for investigating and assessing reasons for exceeding the specified number of trial mold iterations.

6. Workflow and Requirements

6.1 Preparatory Work Before Mold Trial 

6.1.1 Project and mold personnel develop a trial mold plan, and the trial mold personnel prepare materials and the machine.

6.1.2 The assembly department is responsible for implementing the required on-machine trial mold assembly and completing self-inspections as specified.

6.2 Mold Trial Verification 

6.2.1 The first trial of a new mold is conducted by dedicated trial mold personnel from the project department, and they accurately fill out the “Trial Mold Parameter Record Form.”

6.2.2 The person in charge of the trial mold must notify the project department’s responsible person for molds to participate in the trial mold process before the trial.

6.2.3 If there are issues with the mold during the trial but sample parts are needed, project personnel must communicate with the customer to clarify whether samples can be produced first. After completing the samples, the mold can be removed for rectification.

6.3 After the trial mold personnel complete the mold trial debugging, leave five sets of trial mold templates and record the points of the issues. Fill out the “Trial Mold Parameter Record Form” and document the mold’s problem points. Provide this information to the mold-following personnel, who will create a unified mold rectification plan in the “Trial Mold Rectification Plan Form.”

6.4 Upon receiving the mold rectification plan, the head of the machining department must carefully inspect the mold’s own problem points and complete the mold rectification task with high quality and quantity.

6.5 After sending out the samples, the mold-following personnel must promptly follow up on whether there are any changes to the samples. Follow up with the customer to provide assembly information back to the company as soon as possible, facilitating the prompt completion of mold modifications.

6.6 After mold rectification is completed, the quality department inspects the rectified mold, and the project-following personnel are responsible for arranging the next mold trial plan.

6.7 During the subsequent mold trial, ensure proper record-keeping. If the mold has not been rectified properly, repeat the above procedures, rectify again, and reapply for a mold trial.

6.8 The goal for all molds is to undergo a trial three times (including two customer-requested modifications) to be finalized. If there are still issues with the mold itself after the fourth trial, the project personnel will organize a root cause analysis, implement responsibility measures, and issue a warning to the person responsible. If the mold has not been rectified as required by the fifth trial, resulting in additional rectifications, a performance assessment will be conducted on the person directly responsible. Depending on the specific situation of the mold, there will be a penalty of 100-200 yuan for each exceeding trial. If the responsibility lies with assembly, it will be proportionally borne by the relevant assembly team leader and members. If the issue is related to the plan, it will be borne by the project leader.

6.9 If the number of mold trials exceeds the standard due to objective factors such as product design, it can be exempted from assessment after obtaining approval from higher authorities.

6.10 After the mold trial is successful and the assembly team completes the mold and passes the self-inspection, notify the quality department to conduct a comprehensive inspection of the mold. If the mold meets the requirements for factory approval, affix the mold qualification certificate.

6.11 The business department notifies the project department of the mold trial time and location. The project department prints the “Mold and Accessories Handover Receipt,” required by the customer, in duplicate, and submits it to the logistics company for shipment with the mold. The project department should later collect and organize the receipts for preservation.

6.12 Hand over the mold to the customer for production, and the project department tracks the usage of the mold.
