Film Dies

Precise Manufacturing

· Advanced European integrated machining center can meet the processing of any inclined and curved surface, one-time forming with spindle 360° rotating. Length error of 5000mm extrusion die is fixed within ±3μm.

· Alloy steel for die production: P20,2714,2311, SUS420/630,5CrNiMo, etc.

· Die surface treatment can be proceeded with nickel alloy, tungsten carbide, hard chrome and Nano diamond alloy.

For chrome- plated thickness, it is from 0.02 to 0.05mm, hardness is HV900-1000.

· For special requirement for high-quality die lip, it can be processed with tungsten carbide with lip closed angle at R0.03mm.

· International highly-ranked instruments such as Vickers hardness tester, chrome-plated thickness gauge, optical non-contact detector provides accurate testing data.

· KUNZ straightness detector is used to verify straightness tolerance of die lip with high precision and efficiency.

For 1000mm standard extrusion die, tolerance is within ±0.02mm;

For 1000mm precise coating die, tolerance is within ±0.002mm.

More than 35,000 extrusion dies have been sold to 8,000 end users directly or indirectly from more than 30 countries and areas.

Automatic Die

· Automatic die can conduct automatic fine-tuning by the thermal expansion bolt when receives accurate feedback from thickness gauge.

· There is heat insulation device installed between thermal expansion bolt and die body, reducing heat conduction.

· The independent air cooling system optimizes the response time, very suitable for production of low-temperature and heat-sensitive material.

· Efficiently and quickly controls product’s absolute preciseness, with tolerance at ±1%.

· Internal or external deckle can be equipped selectively.
