Automatic Engine Oil Filling Machine

High-Precision Systems for Automotive Lubricants

In the competitive automotive lubricants sector, operational efficiency, absolute volumetric accuracy, and mess-free packaging lines dictate profitability. Harsiddh Unimach Pvt. Ltd. designs, engineers, and manufactures state-of-the-art Automatic Engine Oil Filling Machines specifically built to overcome the unique rheological challenges of filling high-viscosity automotive fluids.

From heavy-duty gear oils and mineral motor oils to advanced synthetic lubricants and multi-grade engine oils, our machinery provides consistent, high-speed, and drip-free volumetric dosing. By integrating cutting-edge automation with robust mechanical construction, we ensure your production facility operates at peak capacity while maintaining strict quality control.

The Challenge of Lubricant and Motor Oil Packaging

Automotive lubricants are highly sensitive to ambient temperature fluctuations. As the temperature in a production plant shifts throughout the day, the viscosity of the oil changes. Traditional pneumatic or gravity-based filling systems often struggle with these variations, leading to under-filling or over-filling, product giveaway, and constant manual recalibrations.

Furthermore, high-speed filling of viscous liquids tends to introduce air pockets, resulting in excessive foaming, bubbling, and messy container lips that disrupt downstream processes like capping and induction sealing.

Harsiddh Unimach Pvt. Ltd. solves these industry-specific roadblocks. Our filling systems utilize advanced electronic dosing technologies that remain completely unaffected by temperature-induced viscosity shifts, ensuring your brand delivers exact weight and volume standards across every single production batch.

Key Performance Features & Technological Advantages

1. Advanced Servo-Driven Precision Dosing

At the core of our machine is an advanced electronic servo-based dosing mechanism. Unlike standard mechanical links, servo motors offer programmable control over rotational speeds and displacement. This setup eliminates the inconsistencies caused by fluctuating oil temperatures and densities, ensuring a repeatable accuracy tolerance of ±0.5% or better.

2. Multi-Viscosity Flexibility

Whether you are running thin automatic transmission fluids (ATF), standard 10W-40 motor oils, or highly viscous 80W-90 gear lubricants, our filling lines adapt effortlessly. The Harsiddh system allows operators to store product-specific filling profiles within the Human-Machine Interface (HMI), drastically reducing changeover times between different product grades.

3. Foam-Free Diving Nozzle Architecture

Engine oil tends to trap air and foam when dispensed at high speeds. To counter this, our machines feature a programmable diving nozzle assembly. The filling nozzles descend deeply into the bottom of the container before dispensing begins, and then rise gradually in perfect synchronization with the rising liquid level. This bottom-up filling technique guarantees a smooth, laminar flow that prevents foam formation.

4. Positive Cut-Off & Anti-Drip Suck-Back Mechanism

Oil drops on the neck or exterior of a bottle prevent induction liners from sealing properly, leading to leaks during transit. Our filling heads are equipped with a pneumatic positive cut-off nozzle design paired with an active suck-back feature. The moment a filling cycle concludes, the system cleanly cuts off the product stream and draws back any residual oil from the tip, ensuring a completely spotless container finish.

5. Sanitary and Heavy-Duty Construction

Built to withstand continuous, multi-shift industrial environments, all product contact parts are fabricated from superior-grade Stainless Steel (SS 316), while the main structure is built from high-strength Stainless Steel 304. The design prioritizes easy sanitization and clean-in-place (CIP) protocols.

Synchronized Operational Workflow: Step-by-Step

Our Automatic Engine Oil Filling Machine functions through a highly synchronized, automated sequence that transitions raw containers into perfectly filled units ready for downstream packaging.

Step 1: Precision Container Entry & Indexing

Empty plastic or glass bottles move along a heavy-duty, variable-speed Stainless Steel slat conveyor. As they approach the filling zone, a robust pneumatic gating and indexing system takes over. This dual-gate setup ensures that containers are held firmly, spaced uniformly, and positioned precisely underneath the filling nozzles, avoiding any misalignment during high-speed runs.

Step 2: Intelligent Sensor Verification

To prevent product waste and mechanical damage, the machine features a network of advanced photoelectric sensors. Before a cycle initiates, these sensors perform a multi-point check:

• Bottle Presence Detection: Confirms that the exact number of containers is present under the filling heads. If a bottle is missing, the specific nozzle will not dispense.
• Downstream Jam Inspection: Checks if the subsequent capping or labeling stations are backed up. If a backup is detected, the filling cycle pauses automatically until the line clears.

Step 3: Controlled Diving Fill Cycle

Once the containers are verified, the servo-driven nozzle carrier lowers the dispensing heads into the bottles. As the precision servo pumps begin dispensing the designated volume of lubricant, the nozzles lift incrementally. This synchronized bottom-up movement maintains a laminar, low-velocity discharge right below the liquid surface, entirely eliminating splashing and air entrapment.

Step 4: Clean Cut-Off & Surface Protection

At the exact millisecond the target weight or volume is reached, the servo dosing stops and the pneumatic cut-off valve closes immediately. Simultaneously, the suck-back vacuum is applied to the nozzle tips. This dual-action mechanism prevents any trailing droplets from falling onto the bottle shoulder or conveyor, keeping the entire line immaculate.

Step 5: Smooth Container Discharge

With the filling process complete, the pneumatic exit gate retracts smoothly. The filled containers accelerate down the conveyor line toward the next crucial manufacturing stages, such as automatic capping, foil induction sealing, and outer labeling, while the entry gate opens immediately to accept the next batch of empty bottles.
