The Seira series — precision automatic batching machines for phosphor powders and silicone adhesives.
Seira-5 — Dual-Station Flagship
The Seira-5 is a fully automatic dual-station batching machine: two stations work simultaneously, dispensing phosphor powders and liquids with balance readability to 0.0001 g. One-button start, continuous cup output, automatic cup feed and discharge — no manual weighing at all.
- Phosphor dispensing accuracy ±0.0005 g; adhesive accuracy ±0.01 g
- Dual balances working simultaneously; 4–5 min per 100 g batch (3 powders + 2 adhesives)
- 12–18 phosphor powders and up to 4 adhesive groups per recipe
- Balances from Mettler, AND, Ohaus or Huazhi — readability 0.0001 g
- Constant temperature & humidity, sealed dry operation, ESD-safe
- Barcode scan verification and label printing (anti-error)
- MES integration, remote recipe switching, full batch traceability
- EMO stop, interlocked safety door, 3-color signal light
- MTBF > 500 h; 12 h phone / 24 h written / 48 h on-site support
Seira Series — Models 1/2/3/6/8
From compact entry machines to high-capacity 24-powder systems, the Seira family covers every scale of LED packaging batching. All models share the same core: sub-milligram weighing, sealed climate-controlled operation, barcode anti-error, and smart recipe control.
- Seira-1 — 6 phosphor powders, 2 adhesives, ±0.0005 g, 7–8 min/100 g
- Seira-2 — 6 phosphor powders, 4 adhesives, ±0.0005 g
- Seira-3 — 6 phosphor powders, 4 adhesives, quick-change adhesive modules
- Seira-6 — up to 24 phosphor powders, 4 adhesive groups, 12 h auto-calibration, laser & level sensors
- Seira-8 — 8 phosphor powders, 1 adhesive, single-station
- One common control platform — easy operator training, one operator runs multiple machines
Integrated Batching Solutions
Complete batching workcells built around the Seira machines: automatic powder-only batching stations, dual-station LED adhesive-powder systems, small-crucible precision dosing, and AGV-integrated material handling — all connected to your MES.
- Automatic single-station powder batching — 24-station powder carousel, Mettler balance, ±0.05 g, 620 g per batch
- MES-driven workflow: recipe download, barcode job creation, auto dispensing, green/red light & buzzer confirmation
- AGV composite robot handling: reads cup labels, delivers cups to machines, routes abnormal cups to a quarantine station
- Dual-station LED adhesive-powder machines for continuous production
- Small-crucible precision dosing for R&D and pilot lines
Proven on Production Lines
Measured results from customer LED packaging lines — manual batching vs. RatioLab automatic batching.
Process Stability
On one customer's line, the RatioLab machine delivered twice the process stability of manual batching — consistent results, batch after batch, shift after shift.
Main Color Bin Yield
On another customer's production line, main color bin yield improved by 6.3 percentage points after switching from manual phosphor batching to the RatioLab machine.
Main Bin Pass Rate
On a third customer's line, main bin pass rate rose 3.53 percentage points — with zero batching errors, 50% less labor, and 2% less consumable usage.
Revenue Impact
Across customer lines, main color bin yield gains of 2–6% translate directly into revenue — the machine pays for itself.
AGV + MES Automated Line
A fully automatic batching line with AGV material handling and an MES-driven workflow, delivered and running on a customer's production floor.
MES Anti-Error Integration
Manual and automatic batching unified under one anti-error MES platform — centralized, traceable data for every batch.
Phosphor concentration is controlled to within 3 parts per 100,000. Across customer lines, main color bin yield gains of 2–6% translate directly into revenue.
