SO-G20 Explosion-proof Coating Large and Small Can Lid Filling Machine

SORUDA SO-G20 is an explosion-proof can capping and filling machine for paint factories and coating producers that fill small and large cans on one line: a pneumatic weighing system delivers 1-30KG per cycle at 150-300 barrels per hour, with ±0.2% filling error. A PLC controller stores 30 filling presets, PTFE seals resist solvents and acids, and the attached pneumatic capper closes lids on containers up to Φ350 x H400 mm.

Technical Specifications

Filling accuracy and output vary slightly with material viscosity, container size and feed flow rate.

Product Advantages

• Explosion-proof construction: the complete system is manufactured to explosion-proof standards with an EXdiaIIBT4 rating, so it works safely in solvent, coating and ink environments.

• PLC programmable control: a PLC controller drives the filling cycle for stable, repeatable weighing results and a long service life.

• PTFE sealing system: all seals use polytetrafluoroethylene, giving resistance to solvents, acids and alkalis so the sealing system lasts longer.

• 30 stored filling presets: the controller holds 30 sets of filling valve parameters that operators simply recall when switching products.

• Filling and capping in one pass: a pneumatic capping machine is attached to the filling station, so large and small cans are filled and lidded without a separate line.

Wide Applications

• Architectural and latex coatings

• Industrial coatings and resin

• Wood and furniture coatings

• Auto refinish paint

• Solvent-based printing and screen printing inks

• PVC and color paste products

• Chemical and solvent packaging

• Paint factories and filling lines

FAQ – SO-G20 Explosion-Proof Can Capping and Filling Machine

What weighing range and accuracy does the SO-G20 offer?

The machine weighs from 1 to 30 KG per cycle with a minimum inductance of 1 g, 2 g, 5 g or 10 g, and holds a filling error of ±0.2% depending on the filling speed. Accuracy is at its best when the feed flow stays steady.

Which container sizes can the SO-G20 fill and cap?

It handles both small-mouthed and open-mouthed barrels with a diameter up to Φ350 × H400 mm. The scale platform measures 400 × 400 mm and the temporary storage countertop is 400 × 1000 mm, so large and small cans run on the same station.

How many barrels per hour can the SO-G20 fill?

Output runs from 150 to 300 barrels per hour, depending on the feed flow rate and the filling weight per barrel. Filling is by bucket type, poured on the bucket mouth.

What is the explosion-proof grade of the SO-G20?

The complete system is built to explosion-proof standards with an EXdiaIIBT4 grade. All seals are PTFE, which resists solvents, acids and alkalis — important when filling solvent-based coatings and inks. Gun tip tubing is SUS304 stainless steel with PTFE, and 316L is optional.

How many filling recipes can the controller store?

The controller stores 30 sets of filling valve parameters. Operators simply recall the matching set when switching products, which cuts changeover time on multi-product filling lines.

What power, air supply and working temperature are required?

The SO-G20 runs on AC220V / 50 Hz, needs a 0.4~0.8 MPa air supply through an 8 mm air pipe, and works in temperatures from -10 ℃ to 40 ℃. The structure is SUS304 stainless steel.
