Tooling Transfer and Mold Maintenance Guide

Tooling Transfer and Mold Maintenance

Moving a mold between factories or maintaining a mold over its production life requires careful planning. Understanding tooling transfer and maintenance processes protects your investment.

Tooling Transfer Considerations

Key considerations: (1) Complete documentation transfer including drawings and BOM. (2) Mold condition assessment with photos before transfer. (3) Reference sample parts for the new factory. (4) T1 samples from new factory require re-approval.

Mold Storage and Preservation

Proper storage: clean and dry mold thoroughly, apply rust preventive, store in controlled environment (20-25C, 40-60% humidity), inspect every 3 months, and plan 2-week reactivation procedure for long-stored molds.

Scheduled Maintenance Plan

After each run: clean water channels, inspect ejector pins. Every 10,000 cycles: inspect slide/lifter wear, clean venting. Every 50,000 cycles: polish cavity, check cooling flow. Every 100,000 cycles: retorque bolts, check water connections.

Buyer's Tip: When transferring a mold to a new Chinese factory, expect 2-4 weeks transition. The new factory may want to modify the mold. Require written approval before modifications and insist on complete documentation. Budget for 1-2 trial iterations.

What This Means for Your Project: Mold maintenance is an investment. A well-maintained mold produces consistent quality 2-5x longer than a poorly maintained one. Budget 2-5% of mold cost annually for maintenance. Maintain a spare parts kit of critical components.
