Harikrushna Machines Pvt. Ltd. (HMPL) manufactures automatic turnkey lube oil packaging machines and high-speed bottling lines for lubricant oil blenders, petrochemical refineries, automotive fluid manufacturers, and industrial oil packaging facilities worldwide. Automotive and industrial lubricants—including motor engine oil, gear lubricant, hydraulic oil, transmission fluid, synthetic motor oil, and heavy machinery greases—demand heavy-duty construction, high filling accuracy, drip-free diving nozzles with active suck-back cutoff, and hermetic induction foil sealing to eliminate transit leakage. HMPL integrates complete monoblock and linear lubricant packaging lines comprising rotary air bottle rinsers, servo-driven volumetric piston and mass flow-meter fillers, induction foil sealing and torque screw capping machines, self-adhesive front-and-back and wrap-around body labellers, and automated check-weighing systems operating at speeds up to 120 containers per minute (CPM).
Petrochemical lubricants display varying viscosities (ranging from light spindle and transformer oils to thick SAE 140 gear oils) that demand active anti-stringing nozzle control and positive container clamping. HMPL lines feature stainless steel slat conveyors with anti-slip wear strips, drip collector trays, and integrated neck clamping that reliably guides asymmetrical 1L, 2L, and 5L HDPE handle jugs through filling, foil induction, and high-torque capping. Packaging engineers configure integrated packaging lines leveraging our specialized Lubricant Oil Filling Machine, Automatic Piston Filling Machine, Turnkey Viscous Liquid Packaging Lines, Screw Cap Sealing Machines, and heavy-duty Jar Labelling Machines.
Heavy-Duty Dosing with Active Suck-Back Nozzles for Multi-Grade Motor Oils
Lubricant oil packaging lines require heavy-duty volumetric dosing systems engineered to handle varying viscosity grades (from SAE 0W-20 up to SAE 85W-140) without droplet dripping or neck fouling. HMPL installs high-speed lubricant oil filling machines and automatic piston filling machines equipped with pneumatic suck-back nozzles, heavy-duty screw cap sealing machines, and high-frequency induction foil sealers.
Non-Aerating Filling for Hydraulic Fluids, Transformer & Base Oils
Mineral oil packaging lines handle conventional petroleum-based lubricants, hydraulic oils, and metalworking fluids across 500ml bottles, 1L flasks, and 5L Jerry cans. HMPL engineers complete bottling lines with turnkey liquid packaging lines, anti-splash bottom-up diving fill nozzles, high-torque capping units, and high-precision jar and bottle labelling machines.
Hermetic Induction Sealing & Net-Weight Precision for Premium Lubricants
Synthetic oil packaging demands zero-leakage container integrity and high-speed throughput for premium multi-grade automotive lubricants. HMPL manufactures automated lines integrating servo-driven lubricant fillers, hermetic induction inner-seal verification, positive container indexing for contoured bottles, and automated check-weighing equipment.
Heavy engine and gear oils exhibit high capillary cling and surface tension, leading to trailing droplets that foul container neck threads and prevent proper foil sealing. HMPL eliminates this through a dual-action nozzle shutoff: an active pneumatic suck-back piston pulls the oil meniscus back into the nozzle orifice at stroke completion, while positive mechanical cut-off pins seal the nozzle tip. A motorized catch pan slides under the nozzles during bottle indexing to guarantee 100% clean bottle exteriors.
Lubricant bottles frequently experience hydraulic pressures and temperature expansion during transportation and warehouse stacking. HMPL integrates high-frequency electromagnetic induction cap sealing tunnels immediately after torque capping. The induction field heats the aluminium foil backing inside the cap liner, hermetically fusing it to the lip of the HDPE bottle neck. This creates a 100% leak-proof hermetic barrier that eliminates seepage, preserves oil quality, and provides obvious tamper evidence for consumers.
Yes. Automotive lubricant manufacturers utilize distinct, asymmetrical containers with offset necks and integrated carrying handles. HMPL designs custom CNC-machined feedscrews, positive neck-gripping orienting guides, and dual-belt side-grippers that stabilize offset-neck bottles. This guarantees exact alignment directly under the filling diving nozzles, induction sealing coils, and front-and-back body labelling applicator heads.
HMPL lube oil packaging lines incorporate comprehensive automated inspection stations to guarantee zero-defect packaging. This includes optical sensors for missing caps and crooked/tilted caps, induction seal verification that detects missing foil liners, and high-speed in-line dynamic check-weighers that inspect net fill weights. Any non-compliant container is automatically diverted via a pneumatic pusher into an offline reject lane without slowing down line throughput.
