Die Casting Tool Transfer | Onboard in 5-8 Weeks

Switching die casting suppliers is high-risk: tooling valued at $5,000-80,000, years of process knowledge potentially undocumented, and production schedules that cannot tolerate extended re-qualification. KastMfg has a structured transition process.

Why Buyers Switch Suppliers

• Quality deterioration: rising scrap rates, inconsistent dimensions, customer complaints
• Service failure: missed deliveries, poor communication, unresponsive project management
• Cost: incumbent pricing uncompetitive after years of price increases
• Financial risk: supplier instability or planned closure
• Capacity: incumbent cannot support program volume growth

The KastMfg Tool Transfer Process

Step 1: Tool Audit (Week 1-2)

Transferred tooling arrives at KastMfg's tool shop. Tooling team conducts:

• Physical inspection: cavity condition, parting line wear, slide condition, cooling channel blockage
• Dimensional check of critical cavity features against drawing
• Shot count history review (if available) -assess remaining service life
• Identification of refurbishment required before first trial

Deliverable: Written tool condition report with findings, refurbishment recommendations, cost estimate, and remaining service life estimate.

Step 2: Process Qualification Trial (Week 2-3)

Tool installed on appropriate machine. Qualification trial:

• Injection velocity, peak pressure, die temperature, cycle time optimized
• First shots inspected for flash, fill quality, ejection behavior
• Parameters locked when first-article quality achieved

Deliverable: Process parameters documented in control plan. First-article inspection report with dimensional results against drawing.

Step 3: PPAP Re-Qualification (Week 4-5, automotive only)

Complete PPAP package prepared and submitted at specified level. Includes: dimensional results from qualification run, material certificates, updated PFMEA and control plan referencing KastMfg's process, initial Cpk data on critical characteristics.

Step 4: Production

Approved program enters scheduled production with full SPC monitoring.

Total Transition Timeline

Phase	Duration
Tool audit	Week 1-2
Refurbishment (if needed)	Week 2-3
Qualification trial + FAI	Week 3-
PPAP submission (automotive)	Week 5-
Customer PPAP approval	Week 7-10+ (customer-controlled)
First production delivery	Week 8-12

Non-PPAP programs: Tool arrival to first production delivery typically 5-8 weeks.

If Previous Tooling Cannot Be Recovered

If the tool audit reveals tooling beyond economic repair or incompatible with KastMfg's machines, we quote new tooling. Gate position and parting line data from the failed tool accelerates new die design. Timeline extends by tooling fabrication duration (5-8 weeks for H13 single cavity).
