2.5 mm thickness suits most digital cutters best for conveyor belts cutting underlay felt pads. These provide optimal balance of cut resistance, air permeability for vacuum hold-down, flexibility, and blade protection across brands like Ruizhou, Jwei, Iecho, Aol, Ruk, Aibang, Jinde, Shilai, Lectra, Zund, Atom, Summa, and EMMA. Thinner options like 2 mm work for light-duty precision cuts, while thicker 4-5.5 mm handle heavy materials but may reduce suction efficiency.
Common Thicknesses by Brand Group
Chinese brands (Ruizhou, Jwei, Iecho, Aol, Ruk, Aibang, Jinde, Shilai) predominantly use 2.5 mm felt conveyor belts, as seen in OEM replacements for models like iECHO PK 0705/7050 and JWEI LST. Western brands (Lectra, Zund, Atom, Summa, EMMA) also favor 2.5 mm for general use, with some like Kongsberg opting for 3 mm kits; 5.5 mm appears for Zund G3 heavy-duty.
Brand Group Recommended Thickness Example Models/Notes
Ruizhou, Jwei, Iecho, Aol, Ruk, Aibang, Jinde, Shilai 2.5 mm
iECHO PK, JWEI LST; customizable from 0.6-20 mm
Lectra, Zund, Atom, Summa, EMMA 2.5-3 mm
Zund G3 (up to 5.5 mm option); anti-static, flame-retardant
Selection Factors
Match thickness to materials: 2.5 mm excels for textiles, leather, vinyl, cardboard up to medium density. Measure existing pad with calipers and check manuals for exact specs to maintain cut quality and warranty. Replace when grooves form to prevent blade damage.
