Attaining the perfect case and carton seal is a balance of the right hot melt packaging adhesive, the ideal operating parameters and a consistent adhesive pattern. Food and beverage manufacturers rely on hot melt packaging adhesives to assure a strong seal for their products. Unplanned downtime on a packaging line can be significantly reduced when hot melt tanks are filled consistently.

Establishing a routine for filling hot melt tanks will keep the packaging adhesive temperature consistent and prevent char formation, which can lead to plugged filters and nozzles. Issues can arise when a hot melt adhesive tank is:

• Filled inconsistently – results in variable adhesive application temperature and pattern
• Filled below a certain level – known as underfilling, results in overheating the adhesives and char formation
• Filled over a certain level – known as overfilling, increases the potential for dead spots and adhesive waste

Providing sign manufacturers with new adhesives and sealants for safer, faster, higher performing, and high quality solutions for sign applications

LOCTITE^® General Purpose Structural Adhesives, powered by hybrid adhesive technology, are a breakthrough in structural bonding for limitless repair.

This case study demonstrates how Henkel and MauserCABS used structural adhesives to replace welding in the redesign of a lighter multipurpose vehicle cabin while also reducing CO2 emissions.

Application Challenges and Objectives

Data center switches, routers, and servers are incorporating larger, more powerful CPUs/GPUs to manage increasing data processing and bandwidth demands.

The new semiconductor packages, many containing multiple large dies, are seeing higher power concentrations, resulting in elevated operational temperatures.

At the same time, new generations of switch, router, and server designs are becoming more compact, which limits the thermal material types that are effective with very thin bond lines.

Customer Challenge

• Modern-day motor drives are integrating more complex power devices to manage growing energy efficiency requirements.  The customer’s next-generation motor controller required a thermal interface material (TIM) to manage new performance challenges and higher power densities. 
• As the IC power module is subjected to motor vibration, reliability and stability of the thermal interface material – with no material migration -- is critical to enable operational integrity.
• Any thermal material selected had to meet challenging metrics: Electrical isolation with high dielectric strength (>5000 Volts) and low thermal resistance are necessary to meet in-application conditions.

Hot melt tank pressure impacts the rate of adhesive flow and amount of product being dispensed. Operators must manage the pressure setting, integrate set speed in the application and avoid adhesive build-up and overspray. Tank pressure is critical to efficiency on the production line.

Preventing char buildup on packaging production lines allows the equipment to run more efficiently. Implementing some simple processes can reduce char buildup and allow hot melt packging adhesive to work more effectively.

Effective Management Maintains Package Integrity and Reduces Waste

Consumer demand for convenience and single-use products continues to grow. At the same time, they want to minimize waste and are choosing more socially responsible products. 

Supply chain challenges have been affecting all manufacturing sectors since the start of the COVID pandemic, and industrial pump manufacture is no exception.

Supply chain issues are often regarded as primarily a purchasing challenge, yet the impact on engineers can be just as great. When specific components become scarce, engineers are in the hot seat to evaluate and qualify alternatives, often under high pressure from purchasing and manufacturing to react quickly.

This article explains the top three ways pump designers can capitalize on and leverage LOCTITE^® solutions that are part of proven best practice in other sectors, to be more robust to withstand future supply chain disruptions. 

While record profits in 2022 positioned oil and gas companies well to invest and develop new strategies (source: Deloitte Oil and Gas Industry Outlook 2023), ongoing uncertainties and competitive headwinds mean that operational resilience and equipment reliability have to be continuing priorities for producers and refiners.

Pipes, tanks, and containment areas each have their own challenges when it comes to maintaining a robust operation, and LOCTITE^® delivers effective, efficient proactive repair and maintenance solutions to keep them running with minimal downtime.  

Gaskets are used to prevent leakage of fluids or gases by forming impervious barriers. For successful gasketing, it is necessary for the seal to remain intact, and leak-free over a long period of time. 

Learn how to secure bearings, bushes and cylindrical parts in housings or on shafts. The aim is to achieve a maximum load transmission capability and uniform stress distribution while eliminating fretting corrosion.

Threaded connections are widely used to connect pipework in pressure systems, thus sealing is essential. The most widely used liquid thread sealant in the automotive repair are anaerobic products. We will show here a repair with a sealing cord.
