Q：How to maintain copper busbar extrusion dies for optimal performance?

A：For copper busbar extrusion dies: 1) Clean die lips daily with brass brushes to prevent oxide buildup, 2) Apply high-temperature anti-seize lubricant (up to 500°C) weekly, 3) Monitor wear on guide rails and replace after 800-1000 production hours to maintain ±0.05mm dimensional accuracy.

Q：What standards do medical-grade plastic tube extrusion dies comply with?

A：Medical tube extrusion dies meet: 1) ISO 13485 for medical device quality systems, 2) USP Class VI material certification, 3) 21 CFR FDA compliance. Features include mirror-polished flow channels (Ra<0.2μm) and corrosion-resistant tool steel to prevent bacterial growth.

Q：Why choose aluminum alloy for precision electronic heat sink extrusion dies?

A：Aluminum alloy dies excel in heat sink production due to: 1) Superior thermal conductivity (150-180 W/m·K) for rapid cooling, 2) Ability to form thin fins (0.3mm thickness) with high dimensional stability, and 3) 50% longer service life than copper alloys when processing 6063/6061 aluminum.

Q：What tolerances can window profile extrusion dies achieve for aluminum alloys?

A：Modern window profile dies deliver: 1) ±0.1mm wall thickness consistency, 2) <0.3mm/m straightness deviation, and 3) surface roughness Ra 0.8-1.6μm. Premium dies incorporate multi-stage flow balancing and H13 hot-work steel for 10,000+ extrusion cycles.

Q：What are the advantages of co-extrusion dies for composite panels?

A：Co-extrusion dies for composite panels enable multi-layer material bonding in one pass, reducing production time by 30-40%. Key benefits include uniform layer thickness (tolerance ±0.1mm), material cost savings through optimized core-layer usage, and enhanced structural integrity with PP/PE/PET compatibility.

Q：What are the advantages of custom ceramic-based composite extrusion dies?

A：Custom ceramic-based composite extrusion dies offer high wear resistance (3-5x longer lifespan than steel dies), thermal stability up to 1200°C, and precise dimensional control (±0.01mm) for complex aerospace/medical components.

Q：How does cold extrusion molding improve precision for automotive parts?

A：Cold extrusion molds (hardness HRC60-62) enable net-shape forming of gear shafts/bearing races with surface roughness Ra0.4μm, eliminating secondary machining while maintaining tolerances within 0.05mm.

Q：Why choose 6061 aluminum alloy for profile extrusion molds?

A：6061 aluminum molds (T6 tempered) provide optimal balance of strength (310MPa yield) and thermal conductivity (167W/m·K), ideal for high-volume extrusion of architectural/industrial profiles at 400-500°C.

Q：What makes extrusion dies suitable for new energy battery casings?

A：Battery casing dies feature multi-stage flow channels and nitride-treated surfaces (HV≥1200) to uniformly extrude thin-walled (1.2-2mm) aluminum casings at 450°C with ≤0.1mm wall thickness variation.

Q：What are the key specifications when selecting copper extrusion molds for busbars?

A：Key specs include: 1) Copper grade (C11000 preferred), 2) Mold hardness (HRB 60-70), 3) Working temperature range (200-600°C), 4) Tolerance class (ISO IT6-IT7), and 5) Surface roughness (max Ra 0.8μm for critical surfaces).
