The automotive industry heavily relies on induction sealing to keep lubricants, oils, and additives from leaking, or from contaminating the material handling process. Automotive chemicals contain aggressive solvents, plasticizers, and other chemicals that can cause damage if they spill. Worse, without proper automotive fluid sealing, end consumers could even be exposed to dangerous automotive chemicals, creating a safety hazard. Some common automotive chemicals that require induction sealing include motor oil, brake fluid, tire sealants, antifreeze, transmission fluid, windshield washer flui, and more. 

Why Rely on Induction Sealing?

Proper automotive packaging with a strong, reliable induction cap sealer will keep these products safely and tightly sealed to prevent leaks of any kind. Without induction bottle sealing, chemicals can leak during transport and distribution, damaging packaging and other products in transit and even leading to shipments being denied upon request. The airtight hermetic seal created by induction sealing also prevents the entry of oxygen or other substances which can degrade the products. Induction sealing ensures the highest of product quality, leading to greater satisfaction from end consumers. 

Increasingly, brands are adopting unique caps which are longer in length than a typical flat cap. While these designs enable brands to adopt flexible packaging for liquids, typical flat sealing coils will fail in these applications. As a result, Pillar's InFinity Tunnel Coil is designed to accommodate these various cap diameters and dispensing designs. The InFinity Tunnel Coil is trusted by major automotive manufacturers to seal their products, such as Valvoline, who used the InFinity Coil to seal their gear oil in a standup pouch. 

Lastly, induction sealing also creates tamper evidence for customers by ensuring that the product arrives to the consumer in the same condition as when it left the factory. It provides anti-counterfeiting measures to ensure that consumers always know they have the real, genuine product - ultimately building trust and reliability with your customers. 

Pillar Induction Sealing Solutions

Automotive chemical sealing requires a strong, dependable induction seal. In addition to this, manufacturing automotive chemicals requires high throughput, with typical lines running 80-120 per minute, ultimately requiring an inducton sealer that can keep up with your production lines. 

• iFoiler Induction Sealer: utilizing a 2.25kW power supply, the iFoiler is 10% smaller and 30% lighter than previous generation systems, making it the ideal induction sealing solution for most cap sealing applications
• iFoiler+ Induction Sealer: the iFoiler+ utiizes a 4.5kW power supply and is the perfect choice for sealing containers with larger cap diameters for high throughput, high speed operations
• InFinity Tunnel Sealing Coil: unlike the Universal Sealing Coil, the InFinity Tunnel Coil applies the electromagnetic field from the sides, with open space above to allow for tall caps to pass through
• Bottle and Cap Detection System: a comprehensive system that utilizes the latest sensor technology to automatically detect one of three fault conditions: stalled bottle, missing foil, or crooked cap; greatly improves quality control by putting a system in place that checks every container for a proper cap seal
• Stacked Light: a three-level, high visibility, stacked light assembly that's mounted to the rear of the inverter to indicate a Run (green), Stop (red), or Loss of Seal (amber) condition to significantly reduce the chances of shipping unsealed products

FAQs About Induction Sealers for the Automotive Industry

Why is induction sealing important for automotive fluids and chemicals?

For manufacturers of automotive products, induction sealing is a crucial safeguard. It helps protect against leaks, evaporation, contamination, and tampering, which can compromise product performance or safety. Whether packaging motor oil, transmission fluid, coolant, or additives, an induction seal ensures your product is delivered intact, ready for use in demanding environments. The added bonus? It enhances shelf appeal and demonstrates product integrity right out of the box.

Can induction seals handle aggressive fluids like oils, lubricants, and brake fluids?

Yes. Induction seals are designed to withstand contact with a wide range of aggressive chemicals and automotive fluids. The key is selecting the appropriate liner material. You will need to choose one that offers chemical compatibility with your specific formulation. At Pillar Technologies, we work with manufacturers to pair the right liner with your container and cap to deliver long-lasting, reliable seals that stand up to even the toughest products.

Are there liners specifically designed for chemical resistance?

Absolutely. Specialty induction liners offer high resistance to chemical breakdown, including formulations commonly used in the automotive sector. These liners can be engineered with barrier layers that resist oil absorption, solvent degradation, and product interaction. This not only extends shelf life but also ensures product purity, helping you maintain quality and meet industry standards.

Are seals safe for hazardous or flammable automotive products?

Yes, when used correctly. Induction sealing is a non-contact process, which makes it ideal for sealing containers with flammable or hazardous liquids. Because the electromagnetic energy heats only the foil in the cap liner (not the product itself), the risk of ignition is minimized. Pillar Technologies offers air-cooled induction sealers that are reliable, easy to maintain, and designed for safe use in industrial environments.

Are there tamper-evident induction seal options for regulatory compliance?

Yes, and they’re highly effective. Tamper-evident induction seals help manufacturers meet regulatory and safety labeling requirements, especially when packaging potentially hazardous automotive fluids. A tamper-evident seal not only helps you comply with DOT or international shipping regulations, but it also builds trust with distributors and end users by clearly showing that the product has not been altered. Pillar Technologies offers tamper-evident liner solutions that are easy to apply, durable, and designed for real-world use in the automotive supply chain.

If you're packaging automotive fluids or chemicals and need a sealing solution that checks every box—performance, compliance, safety, and speed—Pillar Technologies has the tools and expertise to deliver. Let’s talk about optimizing your packaging line for the road ahead.
