Mold Design

Mold design refers to a digital design of a mold. As the initial phase in the Injection Mold Engineering (IME) system, it ensures that the requested design has been carefully assessed before the CNC operators create the mold.

Mold Design Flow Chart

The mold design process starts when the mechanical engineer (ME) creates a record in the Mold Design table with the help of the mold engineers. Once created, ME attaches 2D/3D drawings to the Attachment table and specifies the mold design’s verifier and approvers in the Mold Design Revision History table. Upon submission, TIGA will keep all stakeholders updated by sending notification emails. Once the record is Approved, the mold engineers will continue the mold design process by preparing the mold design’s failure mode and effect analysis (DFMEA), 2D, and bill of material (BoM).

Please check the Status column to monitor the progress of the mold design.

Mold Design Status

Status Name	Description
Open	It is the status of a newly created record.
Design 3D Process	The Mold Design Revision History status is Approved, meaning all approvers approve the submitted record.
Begin DFMEA	The mold engineers link the Design Molding Revision History to the DFMEA table.
Closed	The mold engineers manually update the Mold Design record status when the mold design process finishes.

Creating a Mold Design

To create a mold design request:

1. Create a new record in the Mold Design table.

2. Complete the mandatory fields (shown by *) in the

Mold Design Request/FRM-14-001-007 and Product Specification/FRM-14-001-006 sections.

Upon the request creation, TIGA will send a notification email to the Formulatrix project’s mailing list and update the record status to Open.

Adding an Attachment

Attaching a 2D and 3D drawing in PDF or XT format is necessary to help the mold engineers further understand the request. Follow the standard attachment creation procedure.

Creating Mold Design Revision History

After adding attachments, create a record in the Mold Design Revision History table, and specify the verifier and approvers. ME only needs to complete the Attached Data section as TIGA automatically fetches the data in the FRM-14-001-007 section from the Mold Design table. The following are fields in the Attached Data section and their descriptions.

Field Name	Description
Attached Data	Type of attachment.
Finished Date Plan	Expected finish date of the mold design request.
Verified By	Project leader.
Approver 1	ME manager.
Approver 2	IME manager.
Approver 3	FUSA product manager.

Note

When the record is created, TIGA will set the Mold Design Revision History record to Draft.

Submitting Mold Design Revision History

Mold engineer reviews the Mold Design Request and Product Specification sections in the Mold Design table before submitting the Mold Design Revision History record.

Tip

Read editing records to add product specifications.

To submit mold design revision history:

1. Select a mold design record in the Mold Design table.

2. Open the Mold Design Revision History table on the Related Tables.

   Note

   Only a Draft Mold Design Revision History record can be submitted.

3. Select View Mold Design Revision History in the Actions button.

   

   Mold Design Revision History Report Window

4. Select Submit in the Mold Design Revision History Report window.

Post Condition

TIGA will send a notification email to the verifier and approvers of a mold design request.

Tip

Check the status to track the progress of the Mold Design Revision History record.

Status Name	Description
Open	It is the status of a newly created record.
Submitted	This status shows that the record needs approval from approvers. TIGA will send a notification email to the approvers.
Approved	All approvers approve the Submitted record. TIGA will later send a notification email to the requester.
Revised	The Submitted record is not approved. Tiga will automatically create a Draft record for the requester. Revise the draft before submitting it for approval.

Approving or Rejecting Mold Design Revision History

Only “Injection” group members can approve or reject the mold design request.

To approve or reject a mold design request:

1. Access the mold design using one of the following options:

   • Click on the link in the Design Molding Revision History email.

     

     Approve Mold Design Request Email

   • Go to the Mold Design Revision History table and select a record with Submitted status.

2. Select View Mold Design Revision History in the Actions button.

3. From the Mold Design Revision History Report window, select Approve to accept

   or Revise to reject the record.

Post Condition:

The status of Mold Design Revision History record will turn into Approved, and the system will change the status of the Mold Design record to Design 3D Process after all approvers approve the Mold Design record. If any approver does not approve the request, the system will automatically change the status to Revise and create a new record with a Draft status. Revise and submit the newly created Draft record to submit the Mold Design record.

Approved Mold Design Revision History

Note

TIGA updates the Version field incrementally to show the design history.

Creating or Editing DFMEA and DFMEA Line Items

The design failure mode and effect analysis (DFMEA) mitigates the risk of failure. The mold engineers perform DFMEA to establish and then minimize the part’s Risk Priority Number (RPN). They will ensure that potential hazards are carefully assessed every time the DFMEA evaluation finishes and create a record in the DFMEA table and its line item after the Mold Design Revision History record is Approved. Tiga will change the Mold Design record status to Begin DFMEA when the DFMEA record is created.

Check the description of each field in the DFMEA and DFMEA Line Items window.
