Mold Making for High-Volume Injection Molding

Molds built for high volume

Mold making for high-volume injection molding is a different discipline from low-volume tooling. When a mold must run for years and produce millions of parts, every component needs tight tolerances so each part is consistent and fits with others. Automotive parts, consumer electronics and medical devices all depend on molds that withstand high pressure and keep their shape under stress.

How a high-volume mold is built

• Hardened AISI H13 cavities and cores to resist wear from 30% glass-filled PA66.
• Hot runner to cut cycle time and remove runner scrap on every shot.
• Precise mold components: interlocks, guide pillars and bushings that keep alignment over millions of cycles.
• Optimised cooling for the shortest stable cycle.
• HASCO standard components for easy replacement during long production.

Cost over the whole mold life

A high-volume mold costs more at the start, but it lowers the cost of every part. Saving one second of cycle time or one gram of runner per shot adds up to a large sum over a million parts. We present these trade-offs in the quotation so you can choose the right level of investment.

Inspection and documentation

All critical components are measured on CMM, and the mold is delivered with drawings, a spare parts list and a maintenance plan.

How a project like this works

• Tell us what you need – the mold only, molded parts, or both, and your estimated annual volume.
• Send drawings – STEP, IGES, STL, DWG or PDF, or a sample. We sign off moldability in a DFM review.
• Quotation – tooling price, part price and a schedule, with steel, cavities and runner proposed.
• Mold design approval – you approve the 3D mold design before steel is cut.
• T1 samples + FAI report – production or mold shipment starts after your approval.

Shipping molds and parts

• Molds are cleaned, rust-protected, marked and checked against a shipment checklist: cooling circuits, sprue, locating ring, ejection and support pillars.
• Molds ship with drawings, a spare-parts list and the T1 process sheet.
• Parts are packed to your packing instruction and inspected before shipment.
• We ship to customers in Europe, the USA and Asia.
