Máquina llenadora aceite lubricante

Temperature is the primary source of filling inaccuracy for volumetric lubricant filling systems. For example, SAE 10W-40 motor oil has a density of approximately 0.867 g/ml at 15°C and 0.850 g/ml at 40°C — a difference of 2.0%. A volumetric filler calibrated at 15°C will overfill by 2% at 40°C, resulting in 1L bottles containing 1.020L of product. This translates to significant product giveaway at high production volumes. Our net-weight filling system is inherently temperature-independent: the load cell measures mass directly, and the fill stops when 0.867 kg (for 1L of 10W-40 at 15°C reference) is reached regardless of ambient temperature. The optional temperature-compensated weight mode further adjusts target weight for ambient temperature to ensure exactly 1L fill volume at the reference condition.

Cross-contamination between oil grades (e.g., 5W-30 contaminating 10W-40) occurs when residual product from the previous oil grade remains in the fill nozzle, pipe manifold or pump. Our lubricant filling machines address this with: (1) dedicated nozzle-per-product assignment using color-coded quick-connect nozzles (each nozzle stays with its designated oil grade), (2) a gravity-drain manifold design that drains all residual product back to the bulk tank when production of a grade ends, (3) a CIP (clean-in-place) port on the manifold that allows solvent flush of the entire product pathway between grade changes, and (4) complete pipeline flushing with the new grade before production starts (flush volume discarded). Grade changeover procedure documented in the machine's operation manual specifies the exact flush volume required to clear residual oil to below 0.1% contamination level.

Yes. Our lubricant filling machines can fill both HDPE plastic bottles and steel/tinplate cans on the same conveyor with recipe-based changeover. The conveyor and container handling system uses adjustable guide rails and pneumatic side guides that are set via servo motor to the correct width for each container type. Fill nozzle height, dwell time, fill speed profile and capping head are all stored per recipe. Plastic bottle capping uses a cap press or torque-controlled screw cap applicator. Metal can seaming (for traditional tinplate oil cans with crimp-seal lids) requires an integrated can seamer — this option is available on custom systems. The most common configuration for automotive lubricants is HDPE bottle with snap-cap or screw cap, which our standard filling lines handle without modification.

Our lubricant oil filling machines are supplied with: CE Declaration of Conformity (covering machinery, low voltage and EMC directives), material certificates for all product-contact components (316L stainless steel, food-grade PTFE, FDA-compliant seals), calibration certificate for each load cell (traceable to national standards, OIML R 76 weighing accuracy class III), Factory Acceptance Test (FAT) report with production performance data (fill accuracy, speed, changeover time), and installation qualification (IQ) and operation qualification (OQ) documentation packages. Specific API or ATEX certifications (if required for the product or installation location) are available as options and must be specified at time of order.
