Precision Powder Batching Machines
RatioLab Technologies delivers precision automatic batching solutions for powders and liquids — from LED phosphor pastes to fine chemicals and beyond. Our Seira machines bring sub-milligram accuracy, sealed climate control, and smart recipe automation to every batch, run after run.
Powder dispensing accuracy reaches ±0.0005 g (0.5 mg) and adhesive accuracy ±0.01 g, inside a sealed, climate-controlled chamber that holds constant temperature and humidity. No more variability from manual weighing — just consistent concentration, run after run.
Every machine supports up to 18 powders and 4 adhesives per recipe, with seconds-level recipe switching, remote recipe management, full batch traceability, and MES integration. In LED packaging, our machines raise main color bin yield by 2–6%; wherever precision batching matters, they deliver the same repeatability. Trusted by OSRAM, Everlight, Nationstar, Jufei, Hongli Zhihui and other leading manufacturers.
Why RatioLab
Three things make our batching machines different — precision, environment control, and smart connectivity.
Sub-Milligram Precision
Balances read to 0.0001 g. Phosphor dispensing accuracy ±0.0005 g, adhesive accuracy ±0.01 g — the repeatability your color bin yield depends on.
Sealed & Climate-Controlled
Constant temperature and humidity, closed dry operation, and ESD-safe design protect sensitive phosphor and adhesive materials from the environment.
Smart & MES-Ready
Recipe-driven batching, seconds-level recipe switching, barcode anti-error verification, full batch traceability, and MES networking built in.
Materials We Work With
From phosphor powders to silicone adhesives — if it flows, we can batch it. Not listed? We'll test it in-house.
Industries We Serve
Born in LED phosphor batching — now serving every precision powder and liquid batching application.
LED Packaging
Automatic phosphor-adhesive batching for SMD, COB and high-power LED encapsulation.
Phosphor & Powder Batching
Up to 18 powders per recipe, dispensed to ±0.0005 g with full traceability.
Adhesive & Liquid Dispensing
Silicone and other adhesives dispensed to ±0.01 g — one to four types per batch.
Batch Consistency
Concentration controlled to within 3/100,000 — consistency that lifts yield and cuts waste.
R&D & Small Batch
High-precision small-batch dosing for labs, pilot lines and new product development.
Production Automation
Dual-station machines, automatic batching lines, and AGV-integrated material handling.
