Runner System Options

Hot Runner — High Volume Production Shorter cycle times, no runner waste, lower per-part cost at scale. Recommended for volumes over 50,000 parts.

Cold Runner — Lower Volume & Tooling Cost Lower upfront mold cost, simpler tooling. Best for smaller volumes where runner waste is acceptable.

Suggerimenti per semplificare il processo di acquisto degli stampi

Detailed RFQs Get Accurate Quotes

Submit an RFQ that leaves no room for guessing. Include mold type, cavity count, steel preference, expected mold life, and warranty expectations.

Be Transparent in Your Request

Be clear about the reason for quoting. Don’t ask for a full engineering analysis for a project years down the road.

Respect Intellectual Property

Be discreet when requesting quotes. Do not share ideas from competing mold makers.

Partner with Your Moldmaker Early

Discuss costs and timelines before you’re locked into a design. Effective early collaboration avoids costly revisions.

Keep Communication Ongoing

Ask for regular updates. Many mold makers use Gantt charts or project portals to keep clients informed.

Agree on Payment Terms

Plan for down payments and milestone-based payments, with final payment on approved samples and mold shipment.

Minimize Design Changes

Part design changes after tooling begins delay lead times and increase cost significantly.

Define Completion Criteria

A mold is complete when it produces parts meeting print specifications. All changes after approval require ECOs.

Beware of Unrealistic Deals

If an offer seems too good to be true, it usually is. Mold quality directly affects part quality for millions of cycles.
