Enchedora de tinta

Yes. The SUS316L wetted parts and PTFE seals are chemically resistant to both water-based coatings (latex paints, acrylic emulsions, water-based primers) and solvent-based paints (alkyd enamels, oil-based paints, solvent-based industrial coatings). When switching between water-based and solvent-based products, a solvent flush cycle (approximately 15–20 minutes) removes residual product and prevents cross-contamination. For flammable solvent-based products with flash points below 60°C, ATEX-rated equipment is required.

Net-weight filling is the standard method for pigmented paints because volumetric filling is affected by pigment density variations between colors. Load cell net-weight control measures actual mass regardless of paint density, achieving ±0.3% accuracy. For a 5L tin of dense white paint (density ~1.5 kg/L, total ~7.5kg), ±0.3% = ±22g — well within regulatory tolerance. The system automatically compensates for density changes between color batches without operator adjustment.

For standard paint tins, we offer: press-on lids (the most common format for 250ml–5L tins, sealed by the lid press after filling), lever-lid sealing for 5L–20L round cans, and friction-fit plastic pails for water-based paints. Inline lid feeders and lid press stations are available as integrated components. For tamper-evident requirements, heat-shrink or pressure-sensitive seal options are also available.

Production speed depends on can size and paint viscosity: 250ml–1L tins: 1,500–3,000 cans/hour; 2.5L tins: 800–1,500 cans/hour; 5L tins: 500–800 cans/hour; 10L–20L pails: 200–500 units/hour. High-viscosity paints (above 5,000 cps) reduce filling speed by 20–30% compared to the above. For complete production output calculation, we recommend specifying your product mix (can sizes and viscosities) so we can size the correct machine for your peak throughput requirements.
