Bag-on-Valve Aerosol Filling Line for Automotive Care: 180% Output Surge Case Study

A mid-sized Eastern European manufacturer of automotive care products, including spray waxes and tire shines, faced a critical challenge in Q2 2025: their semi-automatic lines couldn’t keep up with booming demand. By adopting two advanced Bag-on-Valve aerosol filling lines, they increased output by 180%, slashed defects, and streamlined multi-SKU production. This story of transformation shows how the right equipment can turn market pressures into opportunities for growth and efficiency.

The Struggle: Outdated Aerosol Production Stifles Multi-SKU Growth

Picture a bustling factory in Eastern Europe, where a dedicated team crafts branded automotive care sprays—car waxes, glass anti-fog agents, and tire shines—for eager markets across the region. By Q2 2025, this mid-sized business was riding a wave of demand, but their three semi-automatic production lines were buckling. Each line managed only 900–1000 cans per hour (cph), far too slow to juggle multiple SKUs. Switching between products meant lengthy downtime and material waste, eating into profits.

The reliance on four workers per line for tasks like bottle feeding and sealing drove up costs and errors. Filling accuracy wavered by ±1.5g, leading to inconsistent sprays that frustrated customers. A 1.8% defect rate meant rework and returns, while inefficient propellant use added unnecessary expense. The operations manager recalled, “We were losing ground. Customers wanted more, faster, and we needed a solution to stay competitive.” A Bag-on-Valve aerosol filling line emerged as the answer, promising speed, precision, and flexibility for their diverse product range.

The Breakthrough: Advanced Bag-on-Valve Filling Equipment

The turning point came with the decision to invest in two AILE Bag-on-Valve aerosol filling lines, each equipped with a bottle sorting table, nine-head filling, and three-head sealing systems. Unlike traditional aerosols, BOV technology isolates the product in a bag, using eco-friendly propellants like nitrogen to ensure clean, consistent sprays—perfect for automotive care products. This setup minimized changeover times, enabling seamless transitions between waxes, anti-fog agents, and tire shines.

Tailored for mid-sized manufacturers, the automated BOV filling equipment delivered high-speed output with user-friendly controls, requiring minimal training. Its precision addressed quality issues, while eco-efficient design reduced propellant waste, aligning with Europe’s sustainability standards. “The BOV system felt like it was built for us,” the manager shared. “It handled our SKUs effortlessly and promised the scalability we needed.”

Seamless Execution: 8-Week BOV Aerosol Line Integration The deployment unfolded with remarkable efficiency, wrapping up in just 8 weeks. It began with a detailed consultation to align the Bag-on-Valve machine with their product specifications, from viscosity to can sizes. A factory acceptance test confirmed flawless performance before shipping. At the facility, installation was straightforward, fitting into the existing setup without major changes. Training empowered operators to master the system quickly, with only two workers per line needed for bottle loading and quality checks—half the previous requirement. By week eight, the lines were producing consistent batches across SKUs, ensuring no delays in customer deliveries. “The speed of setup was unreal,” the manager noted. “We were back to full speed with better results in no time.” Need help with equipment setup?

The BOV aerosol filling lines catapulted production from 900–1000 cph to 2500–2800 cph—a 180% leap that met soaring demand across Eastern Europe. Labor demands dropped from four to two workers per line, freeing staff for innovation, like new eco-friendly formulations. Quality metrics soared: filling accuracy tightened to ±0.4g from ±1.5g, ensuring flawless sprays. Defect rates plummeted from 1.8% to 0.3%, cutting waste and boosting customer satisfaction. Propellant efficiency improved by 12%, saving 2.1 kg of gas per 10,000 cans, enhancing sustainability and margins. “Our customers noticed the difference immediately,” the manager said. “We’re delivering better products, faster, and at lower cost.”

The Lesson: Powering Automotive Care Manufacturing with BOV Technology

This Eastern European manufacturer’s journey from strain to success mirrors the challenges many growing businesses face: rising demand, limited capacity, and quality pressures. The Bag-on-Valve aerosol filling line offered a tailored solution, blending speed, precision, and eco-efficiency to unlock new potential. Now eyeing broader export markets, this company proves that the right technology can turn obstacles into stepping stones.
