06 / Company Strength
Three questions decide whether a materials partner is actually usable in practice: will they take your quantity, can they prove the material, and can they still deliver when one factory goes down. Here is our answer to each.
Pilot batches, first articles and design-validation runs are accepted at genuinely low quantity. You should not have to buy a year of inventory to find out whether an idea works. Once the design is frozen, volume pricing follows.
We work across multiple ISO 9001 and IATF 16949 certified coating and converting partners, with overlapping qualification on the materials that matter most. One factory's downtime does not become your line stoppage.
Technical enquiries answered within one working day. Formal quotation within 48 hours. Samples typically dispatched in three to seven days, and production in seven to fifteen depending on tooling.
Materials are verified against recognised ASTM, ISO, PSTC, AFERA, FINAT, JIS and GB test methods before we put them in front of you — and again on each qualification lot. Reports are issued with the material.
Measures the force required to remove tape from a standard test panel at controlled speed and dwell time. The primary check on adhesion consistency between lots.
ASTM D3330 · ISO 29862 · PSTC-101Quantifies instantaneous grab on first contact with no applied pressure — the property that decides whether a die-cut part stays where the operator placed it.
ASTM D6195 · AFERA 4015 · FINAT 9Inclined-track measurement of initial tack, giving a fast, repeatable comparison between adhesive batches during incoming inspection.
ASTM D3121 · PSTC-6Static load applied in shear at controlled temperature to measure time to failure. The most honest predictor of long-term creep behaviour under load.
ASTM D3654 · PSTC-107 · GB/T 4851 · JIS Z 0237Backing tensile strength and elongation at break, plus T-peel, lap-shear and floating-roller configurations through interchangeable fixtures.
ASTM D3759 · ASTM D882 · ASTM D1876Verifies that rolls pay off smoothly at production speed. After a supplier change, unwind force is the single most common cause of unexpected line stoppage.
ASTM D3811 · FINAT 3Contact micrometer for total construction thickness and adhesive coat-weight verification, sampled across the web width to catch profile drift.
ASTM D3652 · ISO 534Accelerated ageing under controlled heat and humidity to confirm that adhesion is retained across the full service window, not just on day one.
IEC 60068-2-78 · ASTM D4332Rapid cycling between temperature extremes to expose delamination, embrittlement and adhesive migration long before the customer's field does.
IEC 60068-2-14 · ASTM D3330 (aged)Simulated sunlight, heat and moisture exposure for any material facing an outdoor, backlit or window-adjacent service life.
ASTM G155 · ISO 4892 · ASTM G154Corrosion resistance of foil tapes, conductive constructions and bonded metal joints — essential wherever a conductive adhesive meets a dissimilar metal.
ASTM B117 · ISO 9227Optical dimensional verification of die-cut geometry — inner radii, hole positions, web widths and edge burr — used for first-article and in-process checks.
First-article & in-process inspectionConfirms substrate wettability before adhesive selection. It is the step most often skipped — and the reason a large share of bond failures happen at all.
ASTM D2578 · ISO 8296Static and kinetic friction of liners and films — directly relevant to automated dispensing, pick-and-place reliability and stack handling.
ASTM D1894 · ISO 8295Certifications listed above are held by our manufacturing and converting partners. DINGGU Tape coordinates qualification, testing and documentation across that network — certificates for the specific mill supplying your material are provided on request.
