Die Casting Tooling Ownership | Buyer Guide

Tooling ownership is one of the most important commercial terms in a die casting program. The mold often represents a major upfront investment, and the buyer needs clarity on ownership, storage, maintenance, transfer rights, and records before production begins.

At KastMfg, customer-paid tooling is customer-owned after full tooling payment.

What Tooling Ownership Should Define

Topic	What Buyers Should Confirm
Legal ownership	Who owns the die after payment is complete
Storage location	Where the tool is stored and who controls access
Maintenance responsibility	What routine maintenance is included or charged separately
Shot count tracking	How production usage is recorded
Transfer rights	Whether the customer can move the tool to another supplier
Tool drawings	Whether layout, material, and maintenance records are available
End-of-life plan	What happens when inserts or cavities wear out

These points should be clarified before the tooling PO is issued.

KastMfg Tooling Policy

For customer-funded die casting molds:

• The customer owns the tooling after full tooling payment
• KastMfg stores and maintains the tool during active production
• Tool maintenance records can be shared on request
• Shot count and tool condition can be reviewed during long-running programs
• Tools can be transferred when commercial terms are settled
• Refurbishment or major rework is quoted before work begins

This reduces supplier lock-in and gives buyers more control over the program lifecycle.

Why Ownership Matters

Tooling ownership affects:

• Supplier change options
• Long-term program cost
• End-of-life planning
• Product revision control
• Risk if a supplier closes, changes strategy, or loses capability
• Ability to transfer production during quality or delivery issues

If you are already moving an existing tool, see die casting tool transfer.

Records Buyers Should Request

Useful tooling records include:

• Tool design summary
• Tool steel or insert material certificate
• First trial report
• First article inspection report
• Maintenance log
• Shot count record
• Refurbishment or repair history
• Tool condition report before transfer

These records help the next supplier understand tool condition and reduce re-qualification risk.
