Green PET Die-Cut Tape 230°C | Pre-Cut Masking Dots & Shapes Manufacturer
Green PET Die-Cut Tape 230°C | Pre-Cut Masking Dots & Shapes Manufacturer
Green PET Die-Cut Tape 230°C | Pre-Cut Industrial Masking Solutions
Precision die-cut masking dots, discs, rings, and custom shapes engineered for high-temperature powder coating bake ovens, anodizing baths, and PCB electronics manufacturing.
High-Speed Pre-Cut Masking Efficiency
Eliminate time-consuming manual cutting and inconsistent tape overlap on production lines. Our Green PET Die-Cut Masking Tape combines a heavy-duty polyester carrier film with a cross-linked silicone pressure-sensitive adhesive. Built specifically to handle 230°C bake cycles for up to 30 minutes, these pre-cut pieces maintain sharp masking boundaries without shrinking, edge lifting, or silicone adhesive transfer.
Standard & Custom Die-Cut Formats
🟢 Pre-Cut Masking Discs
Standard diameters from 3mm to 120mm on easy-release split liners. Ideal for sealing threaded blind holes, grounding points, and bolt holes during powder spraying.
🏷️ Extended Pull-Tab Dots
Features non-adhesive extended side tabs ("finger lift") that allow operators wearing thick work gloves to apply and remove masking dots in seconds.
📐 Custom CAD Geometry
Precision die-cutting manufactured to your exact engineering DXF/DWG drawings, supplied on continuous rolls for automated robotic pick-and-place systems.

Q: How much labor time can pre-cut green PET die-cuts save compared to roll tape?
A: Switching from roll tape to pre-cut masking dots or custom shapes typically reduces masking labor hours by 50% to 70% in high-volume powder coating or electronics assembly operations while eliminating operator errors.
Q: Does this green PET tape leave silicone residue after 230°C oven cycles?
A: No. Our high-temperature cross-linked silicone adhesive peels off cleanly in one piece from aluminum, steel, brass, and PCB substrates without leaving ghosting, oil films, or sticky residue.
Q: Can you supply pre-cut masking dots on continuous rolls for automated dispensers?
A: Yes! We supply die-cut discs on continuous release liner rolls with the waste matrix removed, making them fully compatible with automatic pick-and-place dispenser machinery.
Q: What is the minimum order quantity (MOQ) for custom CAD die-cut shapes?
A: We keep standard diameter discs (e.g., 5mm, 10mm, 12mm) in stock with low MOQs. For custom shapes, we provide quick-turn prototype sample runs so you can verify fit before full production.
