Multi-Cavity Mold for Precision Parts

Multi-cavity molds for precision parts

A multi-cavity mold produces several identical parts in each shot. For small precision parts in consumer electronics, that is the only way to reach the volumes and part prices the market expects. But every cavity must produce the same part: if one cavity runs slightly bigger or fills later, the parts from that cavity fail inspection.

What makes multi-cavity molds different

• Balanced runner so the melt reaches every cavity at the same time and pressure.
• Identical cavities, machined from the same program and checked on CMM, so dimensions match across cavities.
• Cooling designed so each cavity sees the same temperature.
• Venting at every cavity to prevent burns and short shots.

This mold uses AISI H13 cavities and a cold runner on a HASCO base, listed for 30% glass-filled PA66 parts.

Lead time matters in electronics

Consumer electronics change every season, sometimes every few months. A mold maker with complete machining capacity in-house can keep the mold schedule under control. Our project management team follows every step of component machining, and every component is inspected before assembly, so the mold reaches T1 on time.

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.
