Copper/nickel/silver-plated polyester fabric delivers flexible, low-resistance EMI shielding (60–90 dB). Conductive adhesive films use silver/copper/nickel-filled acrylic on PET, fabric, or foam carriers — available in isotropic (3-axis) or anisotropic (Z-axis) construction for both bonding and electrical continuity. Engineered for consumer electronics, displays, and automotive applications: EMI gaskets, grounding pads, FPC bonding, and component retention. Precision die-cut to your drawings, with configurable adhesive and non-adhesive zones for high-volume automated assembly.
High-strength bonding solutions for automotive and home appliance industries. Closed-cell acrylic foam with excellent temperature resistance and water resistance.
High bonding strength, shock absorption, temperature and aging resistance, water and moisture resistant. Can be die-cut to any shape and size, replacing screws and rivets to simplify assembly. Ideal for electronic component mounting, nameplate bonding, automotive parts, home hardware, and plastic/metal part bonding.
Roll-form double-sided tape (also called jumbo-roll or roll-stock double-coated tape) is a pressure-sensitive adhesive tape supplied in continuous roll format. It is coated with adhesive on both sides and backed by a release liner (paper or film) on one face. Unlike precut sheets or individual die-cut pieces, its primary advantage is that it is designed for automated, high-volume production. The entire process—unwinding → lamination → die-cutting → liner rewinding—runs continuously in a single pass with minimal manual handling. It is widely used across the electronics, automotive, and home appliance industries for large-scale bonding and tape-backing operations.
Thermal double-sided tapes and silicone thermal pads die-cut to specification. High thermal conductivity, low thermal resistance, and high compressibility. Flame retardant and insulating, effectively fills assembly gaps. Essential for CPU, GPU, power supplies, battery modules, LEDs, and renewable energy electronics.
A polyimide-film-based insulating tape with a high-temperature silicone PSA. Standard thicknesses are 25 μm and 50 μm; rated −269°C to +260°C continuous, Class H, UL94 V-0, residue-free after soldering. Used for PCB gold-finger masking, SMT reflow/wave-solder protection, lithium-battery insulation, motor/transformer winding, and aerospace harnesses. Pick 25 μm for fine-pitch work, 50 μm for general insulation.
We specialize in custom die-cut foam gaskets in PU, PORON® (Rogers), and EVA. The foam is laminated with pressure-sensitive adhesive (PSA) on one or both sides, then precision die-cut to your drawings. Widely used for dust sealing, EMI shielding, and shock absorption in consumer electronics, wearables, and automotive electronics.
A sealing and cushioning tape built on a closed-cell polyethylene (PE) foam backing, coated on both sides with acrylic pressure-sensitive adhesive (PSA). Standard thickness: 0.15–3.0 mm. The closed-cell structure delivers IPX7 waterproofing (IPX8 for cross-linked grades). The foam compresses 20–40% to fill gaps and absorb shock, and is easily die-cut into custom gaskets and shapes. Widely used for display and battery sealing in consumer electronics, interior bonding in automotive, panel mounting in appliances, and sealing in window/door and solar PV assemblies.

For engineers specifying a die-cut bonding component, the choice between acrylic and silicone adhesive is rarely decided by peel strength alone. The two chemistries behave very differently on low-surface-energy plastics, under thermal cycling, and when the bonded assembly has to survive decades in the field. This guide compares them across the parameters that actually drive field failure.
Acrylic adhesives bond best to surfaces above ~38 dynes/cm — treated metals, glass, ABS, PC and PET. On HDPE, PP, powder-coated or silicone-rubber surfaces, standard acrylic will delaminate regardless of how high the initial peel number looks on the datasheet. Silicone adhesive tolerates low-energy surfaces down to ~28 dynes/cm and is the default choice for bonding silicone keypads, rubber gaskets or fluoropolymer films.
Choose acrylic when: you are bonding standard engineering plastics or metals, cost matters, and the assembly lives in consumer-electronics or general industrial environments. Acrylic also offers cleaner aesthetics and better conformability to textured surfaces.
Choose silicone when: the substrate is low-surface-energy, the application sees high temperature or sterilisation cycles, or you need a release liner that itself is silicone-coated without contamination. Silicone's trade-off is higher cost, lower tack on high-energy surfaces, and the risk of silicone migration that can later interfere with painting.
If you are unsure, send us the substrate, operating temperature and a sample part. Our engineering team will recommend a specific adhesive and run a free die-cut prototype within 3–7 days.
Foam gaskets and cushioning pads look similar on the drawing, but choosing between PU, PE, EPDM, silicone or PORON® changes compression set, water ingress and product lifetime. Below is the decision framework our DFM engineers use when a customer sends a sealed enclosure or drop-test requirement.
Best for wide temperature ranges (−60 °C to +200 °C continuous), UV and weather resistance, and food/medical contact. Higher cost, but the only realistic option for outdoor LED seals or appliance oven gaskets. Closed-cell grades provide excellent water sealing.
The default for outdoor IP-rated enclosures. Good ozone and UV resistance, low water absorption, and a compression set that holds over many years. Slightly less rebound than silicone at extreme temperatures, but typically 30–40% cheaper.
Excellent rebound and cushioning for drop and shock applications — used in phone battery packs, keypads and display bezel seals. Closed-cell PU resists dust; open-cell grades are acoustic. Temperature limited to roughly −40 °C to +90 °C.
Lowest cost, good chemical resistance, and widely used for gasketing in consumer electronics and packaging cushioning. Higher compression set than PU or EPDM — acceptable for static seals but not for dynamic re-assembly.
The carrier film under your adhesive is often the quietest driver of performance. A double-sided tape is not just the glue — the PET or PI film sets dimensional stability, dielectric strength and temperature ceiling. Here is how the common substrates compare.
The workhorse. 25–125 µm thicknesses, excellent dimensional stability, good electrical insulation, low cost, and a smooth surface that plays well with acrylic adhesives. The default choice for nameplate bonding, display bonding and general industrial applications. Continuous use to ~150 °C.
The high-temperature specialist. Amber colour, continuous use to +260 °C, outstanding thermal stability, used in reflow pallets, EMI shielding and aerospace flex circuits. Cost is roughly 5–10× PET, so specify it only when temperature or UL flammability genuinely requires it.
PU, PE or acrylic foam provide bonding plus gap-filling and stress relief in one part. Ideal when surfaces are uneven or the assembly needs vibration damping — the VHB family is the classic example.
Neoprene, silicone, EPDM and fluorosilicone used when the part itself must seal, gasketing, or provide EMI shielding. Usually die-cut to thickness tolerances of ±10% rather than the ±10 µm achievable on films.
Double-sided tape failures at high temperature usually have one root cause: the datasheet's "continuous use temperature" was confused with peak exposure, or the wrong substrate was chosen. This is the decision process we walk customers through when the application sees reflow, IR reflow, under-hood or near-heat-source conditions.
A tape rated to 150 °C continuous will survive 260 °C for 60 seconds (typical SMT reflow profile). It will not survive an hour at 200 °C. Specify both numbers on your drawing: the steady-state operating temperature and the shortest thermal cycle the part must endure.
High-temperature bonds fail more often from outgassing or oily contamination than from adhesive chemistry. Isopropyl alcohol cleaning and, on low-energy plastics, a corona or plasma treat step matters more at temperature than selecting a "hotter" grade.
Run a thermal cycle test on a die-cut sample before locking the BOM. We produce free prototypes so you can verify the bond in your own thermal chamber.
A die-cut part is only as producible as its drawing. Most tooling problems, part defects and cost overruns we see come from five predictable design choices. These guidelines are based on what our rotary and flat-bed dies actually cut in production, not textbook theory.
Never design a web narrower than the material thickness (for film) or 1.5× the material thickness (for foam or rubber). A 0.1 mm PET web in a 1 mm foam part will tear on the matrix and force a re-tooling. When the part pattern has many holes, call out a minimum web on the drawing — it saves a design review cycle.
A razor knife cannot cut a true sharp inside corner without a radius. Specify an inside radius of at least 0.3 mm; on thick foams (≥1 mm), use 0.5 mm or larger. Sharp internal corners fracture the die steel and produce ragged edges. If a sharp corner is functionally required, plan a secondary post-punch step rather than expecting the die to do it.
The smallest reliably punched hole in film is roughly 1.5× the material thickness; in foam, 2× thickness. A 0.5 mm hole in a 1 mm foam pad will not hold tolerance and may bridge. Design holes larger than this, or switch to a rotary or laser process for micro-features.
Do not put ±0.05 mm on every dimension. That tolerance is achievable on flat-bed or laser cutting but not on high-speed rotary — and it doubles tooling cost. Put tight tolerances only on the critical mounting holes and assembly interfaces; leave general dimensions at ±0.15 mm (film) or ±10% thickness (foam).
Specify which side faces up on the liner, the liner colour, and whether kiss-cut matrix needs grid lines for automated pickup. Missing these notes is the most common cause of a first article that does not match assembly expectations.
Send us your drawing before tooling. Our DFM team reviews it free and flags every dimension that will cost you money or delay the sample.
"What tolerance can you hold?" is the most common first question on a drawing — and the answer depends on which process cuts the part. Specifying a tolerance that the process cannot economically hold either raises price or produces rejections. Below are the working tolerances our shop holds in production.
High-speed, lower cost, but the die is flexible and the material stretches slightly as it feeds. Expect ±0.10–0.15 mm on parts up to 200 mm; ±0.20 mm on larger nests. Ideal for high-volume consumer electronics where absolute precision is not the deciding factor.
More rigid die, tighter tolerances: ±0.08–0.10 mm on small to medium parts, ±0.15 mm on larger nests. Slower than rotary, so the sweet spot is mid-volume production and first-article verification.
No tooling cost and the tightest tolerance: ±0.05 mm or better on flat film up to about 500 mm. The trade-off is speed, edge char on foams, and a heat-affected zone that can matter on adhesive surfaces. Best for prototypes, low-volume custom parts and micro-features.
Part geometry tolerance is different from material thickness. On film, thickness is controlled to the adhesive manufacturer's spec (typically ±10%). On foam, expect ±10% to ±15% thickness, which matters when the foam must fill a precise gap. Specify the material grade, not just "black foam", to lock this in.
Send your drawing — we will confirm what each process can hold →
After reviewing thousands of customer drawings, a small number of design errors account for most first-article surprises. If you recognise any of these on your drawing, fix it before tooling — it is cheaper than another sample round.
A die knife is a straight piece of steel bent to shape; it cannot produce a sharp internal corner without a radius. Expect ragged corners and broken dies if you call out 0 mm radius. Minimum 0.3 mm, preferably 0.5 mm on thick materials.
0.3 mm holes in 1 mm foam do not punch cleanly. The die bridge between adjacent holes also collapses if the web is under 1.5× material thickness. Either enlarge the features or switch to laser cutting.
Die cutting is not CNC machining. ±0.02 mm on every dimension forces flat-bed tooling and triples the unit cost. Reserve tight tolerances for the 2–3 dimensions that actually mate to another part; leave everything else at ±0.15 mm.
Leaving off liner side, colour and whether the part must stay on a carrier forces a guess. Automated assembly fails when the liner is the wrong side. Specify: "part face up on 75 µm blue PET liner, matrix grid every 50 mm".
A 200 oz/in peel number on the datasheet is measured on stainless steel at room temperature. On your oily PC enclosure at 85 °C the same tape may be far weaker. Specify substrate, temperature and cycle conditions — not just a peel rating.
"Black foam gasket" is not a spec. The supplier will choose whatever is cheapest, and it may not match your compression or sealing requirement. Specify material family, thickness, density and a reference grade (e.g. "3M 4647 equivalent, 1.6 mm").
Most of these mistakes disappear in one drawing review. Send us your PDF — we annotate it with production notes at no charge.
Kiss cutting and through cutting are not interchangeable options — they drive entirely different downstream assembly, tooling and cost. Choosing the right one at the design stage is cheaper than re-tooling after the first article.
The knife cuts through the adhesive and carrier but stops cleanly on the release liner. The part stays on a continuous liner, in a fixed pitch, ready for robotic or roll-fed assembly.
The knife cuts completely through adhesive, carrier and liner. The finished parts are loose, either bulk packed or on a easy-peel sheet.
When you send your drawing, tell us how the part will be assembled. We will recommend the process that minimises total cost, not just unit price.
