18″ x 13″ 60W LED UV Exposure Unit
Brand: SAHUANIYE
Key features include a rust-proof iron body with electrostatic coating for durability, a countdown timer with automatic shut-off, and a memory function that retains the last timing setting. A high-density sponge (7.87″ x 11.81″ x 2.36″) aids in pressing the film more tightly, improving plate exposure quality. The unit supports heavier weights placed on the sponge to ensure even exposure across the plate.
Caydo 100W UV Exposure Unit
Brand: Caydo
Features a 100W UV exposure lamp with 395nm wavelength, delivering faster exposure times (about 1.5 minutes for standard emulsions) and uniform light distribution. Includes a timing device with adjustable exposure from 0.5 to 9.5 minutes and a memory-ready display for subsequent uses. The frame supports screens from 10 x 14 inches up to 20 x 24 inches, making it versatile for various project sizes.
INTBUYING UV Exposure Unit 20×24 Inches
Brand: INTBUYING
Tabletop design with complete accessories for maintenance. A digital timer offers precise exposure control with a range of 1 second to 99 hours, plus automatic memory of prior settings. Eight LED UV tubes ensure even exposure across a 20″ x 24″ area, which supports various emulsion thicknesses. The unit features automatic shut-off when exposure time ends and includes shading cloth to protect operators from UV exposure.
INTBUYING UV Exposure Unit 18×12 Inches
Brand: INTBUYING
Compact 18″ x 12″ exposure area with 60W power and a 395nm wavelength. It ships with four 15W LED tubes and includes a press-friendly sponge (7.87″ x 11.81″ x 2.36″) plus a shading cloth for operator protection. The digital timer supports automatic shut-off and has a memory feature to recall prior settings, streamlining repeated production workflows.
YHISUAILO UV Exposure Unit
Brand: YHISUAILO
Features four 15W lamps (total 60W) and a 46 cm x 32 cm irradiation area. Constructed with eight-mm toughened glass panels for safety, the unit includes a timer with automatic memory to reuse previously set exposure times. A shading cover protects operators during exposure, and the design emphasizes durability and long service life with spare parts available for maintenance.
TECHTONGDA UV Exposure Unit 20×24 Inches
Brand: TECHTONGDA
This unit combines an 8-lamp setup (20W each) for a total of 160W, supporting a 21″ x 25″ exposure area. It emphasizes improved exposure through a close contact press system, aided by two black sponges to press the film. A countdown timer with automatic memory ensures consistent timing across sessions, letting users repeat precise exposure times with ease.
Buying Guide
When selecting a silk screen light box, consider exposure area, lamp type, and timer features. LED lamps offer longer life and lower heat, helpful for sensitive emulsions. Larger exposure areas support bigger screens, reducing the need to tile exposures. Timers with memory simplify repeated workflows and reduce setup time. Build quality matters: a sturdy frame and stable base prevent movement during exposure and improve consistency. Accessory provisions—sponges for pressure, shading cloth for operator protection, and spare parts—affect long-term maintenance and performance.
Key purchase considerations
- Exposure area: Choose a size that matches your largest screen to minimize multiple exposures.
- Lamp configuration: More LEDs generally mean more uniform exposure and longer life; verify wattage and wavelength compatibility (common around 395 nm).
- Timer reliability: Look for digital timers with memory and automatic shut-off to prevent overexposure.
- Durability: Steel or iron frames with durable coatings resist rust and wear in workshop environments.
- Ease of use: Tabletop units save space; ensure cables and sockets are safely organized and accessible.
- Maintenance: Check for availability of spare LED tubes and replacement parts in case of long-term use.
Performance comparisons
- Speed: Higher wattages (e.g., 100W) typically reduce exposure time for standard emulsions, boosting throughput.
- Versatility: Units with wide range of screen sizes (10 x 14″ to 20 x 24″) suit growing studios and varying projects.
- Safety: Models with shading cloth and protective features minimize operator UV exposure.
In summary, selecting a silk screen light box involves balancing exposure area, lamp quality, and timer functionality. The options above cover a spectrum from compact, budget-friendly units to larger, feature-rich models suitable for professional setups. Consider your typical screen sizes, preferred workflow, and maintenance plans to determine the best fit for your screen printing needs.
