FAQ
Q: Are your die-cut tapes genuine original 3M/Avery Dennison materials? Can you provide certificates?
A: We are official authorized distributor of major adhesive brands. All tapes are sourced directly from factories. Batch delivery documents, MSDS, RoHS and flame retardant test reports are available for audit and traceability, fully compliant with automotive and lithium battery standards.
Q: Can you do multi-layer, ultra-thin & irregular tape die-cutting? What’s dimensional tolerance?
A: Multi-layer lamination, liner separation, 0.03mm ultra-thin and custom irregular shapes are available. Produced in clean room, standard tolerance ±0.1mm, precision electronic parts ±0.05mm, burr and dust free to protect delicate components.
Q: Which industries do your die-cut tape products serve? Do you have auto & battery relevant certifications?
A: We supply mobile terminals, 3C electronics, new energy lithium batteries, automotive electronics and industrial control equipment for screen bonding, EMI shielding, insulation and sealing. We hold ISO9001, IATF16949, ISO14001 and ISO45001 certifications to meet factory audit standards.
Q: Can you customize high-temperature, residue-free and conductive die-cut tape parts for different working conditions?
A: Custom functional tapes are available: high-temperature resistant tape for soldering, residue-free tape for temporary fixation, conductive EMI shielding tape, thermal conductive tape and flame retardant tape for lithium battery safety, stable adhesion without warping.
Q: Will multi-layer die-cut tapes delaminate or overflow adhesive? How do you control quality?
A: Constant temperature & pressure lamination lines avoid glue overflow and separation. Full inspection on appearance, adhesion and dimensions before shipment to reduce defective rate for mass assembly.
Q: Can I get tape die-cut samples? Is there sampling charge?
A: Standard samples are free, customers only cover courier cost. Complex multi-layer automotive samples require a small sampling fee, fully deductible on subsequent mass orders. Samples shipped within 24–48h after receiving drawings or physical samples.
Q: What is your MOQ? What is your production capacity?
A: No strict MOQ for R&D trial orders. MOQ for regular tapes: 500pcs; large auto & battery composite tapes: 1000pcs. Multiple automatic die-cut lines with daily output up to millions of pieces. Large stock of brand tapes ensures stable supply in peak seasons.
Q: What is standard lead time? Can you arrange rush orders?
A: Samples within 2 days; small batches 3–5 days; bulk standard orders 5–7 days; complex IATF automotive tapes 7–10 days. Rush priority production is available for new product trials and urgent restocking.
Q: How do you pack finished tapes? Can neutral or custom export packaging be provided?
A: Inner anti-static PE bags + release film protection, outer thick moisture-proof cartons. Neutral blank export packages, custom brand color boxes and vacuum moisture-proof packaging are optional for sea & land transport to avoid deformation and glue overflow.
Q: What payment terms do you accept? Is credit term available?
A: Domestic clients: corporate bank transfer, Alipay, WeChat corporate account. Overseas clients: T/T, L/C. New clients pay 30% deposit before production, full balance before delivery. Flexible credit terms can be negotiated for long-term partners.
