UV-LED SYSTEMS FOR YOUR PROCESS

Adhesive, dispensing, and UV exposure from a single source.

Repeatable UV curing requires the precise interaction between the adhesive's photoinitiator spectrum, irradiance (mW/cm²), emission wavelength (365 nm, 385 nm, 395 nm, 405 nm, or 450 nm), and component geometry. As a specialist for bonding and dispensing technology in Widnau (St. Gallen Rhine Valley), we do not merely supply individual UV lamps – we align the UV-LED curing system, light-curing adhesive (ThreeBond), and UV-blocking dispensing technology (Musashi Engineering) as an end-to-end production process.

For manual workstations, laboratories, and automated fixtures, we offer the compact light sources dropflow Cure 1G, Cure 2G, and Cure 1G Industrial. For high-speed multi-point curing in fractions of a second, the multi-channel spot curing systems of the Awellcure AS01-4 / A2400-TP4 Touch series provide up to 18,000 mW/cm², complemented by light-shielded UV-LED curing chambers (UV-Cubes O100100 / O250250) as well as linear and area UV-LED flood arrays.

04 / OPTICS, INTERCHANGEABLE LENSES & LINE INTEGRATION

Interchangeable Optics &Focusing Lenses

Selecting the right lens and head geometry focuses the UV beam precisely onto the bond line: from micro-fine 2 mm spots with extreme peak irradiance (18,000 mW/cm²) and line beams (3 × 15 mm, 5 × 20 mm) for adhesive beads to 90° side-beam optics for bores. This eliminates stray light and achieves the shortest cycle times.

Which UV-LED systems and UV curing chambers (UV-Cubes) does dropflow supply in Switzerland?

Our portfolio covers all industrial UV curing tasks: mobile and USB-controllable UV-LED pen light sources (dropflow Cure 1G, Cure 2G, and Cure 1G Industrial), high-intensity 4- to 12-channel spot curing systems (Awellcure A2400-TP4 Touch / AS01-4 with up to 18,000 mW/cm²), closed UV-LED curing chambers (UV-Cubes O100100 for 100 × 100 mm and O250250 for 250 × 250 mm with stainless-steel reflector interior and door safety interlock), as well as linear and area UV-LED flood lamps (AF3050H1, AFL50, AFL100, and custom arrays up to 20 × 440 mm).

What advantages does dropflow offer for UV curing equipment in the St. Gallen Rhine Valley and Eastern Switzerland?

From our location in Widnau (St. Gallen Rhine Valley), we support industrial manufacturers across Switzerland, Eastern Switzerland (Heerbrugg, Balgach, Au SG, Altstätten, Buchs SG, Goldach, St. Gallen, Thurgau), and Liechtenstein personally on site. Unlike lamp-only distributors, dropflow provides a matched end-to-end system combining UV-LED exposure hardware, light-curing ThreeBond industrial adhesives (TB3000/TB3100 series), and UV-blocking Musashi precision dispensing equipment – including local curing trials and short delivery lead times.

How do dropflow Cure 1G, Cure 2G, and Cure 1G Industrial differ?

The dropflow Cure 1G is a compact, battery-powered handheld unit (365 nm or 405 nm, 250 mW typ.) for fast cordless spot curing in field and assembly work. The dropflow Cure 2G adds a precision timer (1.0–120.0 s), adjustable irradiance (10–100 %), and PC software control. The dropflow Cure 1G Industrial features a cylindrical 25 mm clamping sleeve for fixed fixture mounting and a Software Development Kit (`ilumCURE.dll` for LabVIEW, C#, Python) capable of controlling and monitoring up to 127 units simultaneously via USB.

Which wavelength (365 nm, 385 nm, 395 nm, or 405 nm) do I need for my UV adhesive?

The optimal wavelength depends on the adhesive's photoinitiator and the UV transmittance of the substrates: 365 nm provides excellent surface curing (e.g., for cationic UV epoxies, electronics potting compounds, and UV silicones), whereas 385 nm, 395 nm, and 405 nm penetrate deeper into thicker bond lines and through UV-stabilized or slightly tinted plastics. We match your technical datasheet (TDS) directly against the spectral output of our LED heads.

How can UV-LED spot curing systems and curing chambers be integrated into a PLC line?

Awellcure controllers (such as the 4-channel A2400-TP4 Touch as well as the flood and chamber controllers) feature a rear 24-pin digital PLC terminal block (per-channel triggers CH1–CH4, master trigger ALL, emergency stop EMER, plus status signals READY, BUSY1–4, and ERROR), an RS232 serial port, and a foot pedal jack. Step and pulse profiles can also be stored to minimize shrinkage stress and peak temperatures in sensitive components.
