Redesigning AC Indoor Unit Packaging for High-Volume Dispatch

Redesigning AC Indoor Unit Packaging for High-Volume Dispatch

A Customer-Centric Case Study

When a major air-conditioning manufacturer began scaling dispatch volumes, the packaging system quickly became a constraint.

Indoor AC units were being packed using thermocol endcaps. The solution provided basic cushioning but created operational and logistics limitations. The packaging increased carton size, added material complexity, and required careful handling to avoid damage during distribution.

For a product moving through large distributor networks and multi-stage handling, protection needed to be reliable, repeatable, and efficient at scale.

The manufacturer required a packaging system that could match the usability of existing thermocol endcaps while delivering stronger structural performance and better logistics efficiency.

The Situation: High-Volume Dispatch with Sensitive Components

Indoor AC units combine rigid outer housings with delicate internal assemblies such as heat exchanger coils, electronic control boards, and plastic structural parts.

During distribution, units experience multiple stress points:

Repeated handling

Products are moved across factory floors, warehouses, loading docks, and dealer networks. Handling can involve forklifts, clamp lifts, stacking, and manual transfers.

Impact exposure

Cartons may be dropped during loading or movement. Even minor drops can create internal stress on components if packaging does not absorb the impact effectively.

Long-term stacking

Large quantities are stored in distribution centres for extended periods, often under stacked loads that remain in place for months.

The manufacturer required a packaging system capable of managing these risks while maintaining operational simplicity on packing lines.

The Engineering Challenge

The objective was clear: replace thermocol protection without disrupting the existing packing process.

Packaging needed to deliver:

  • Drop protection from multiple orientations
  • Stability during high stacking loads
  • Compatibility with clamp lift handling
  • Reduced carton dimensions to improve logistics efficiency
  • Reliable performance in challenging environmental conditions

 

At the same time, the system had to integrate easily with existing production workflows.

Significant process change was not acceptable.

Honecore’s Approach: Replicating Familiar Handling with Structural Engineering

Honecore developed a patented honeycomb-based endcap system engineered to mimic the form and handling characteristics of traditional thermocol endcaps.

This approach allowed operators to use the new system without retraining or changes to packing procedures.

The protection structure is built using engineered paper honeycomb cores configured to absorb impact and distribute load across the packaging structure.

Key design characteristics include:

  • Honeycomb endcaps shaped to match existing packing configurations
  • Structural compression zones that dissipate drop energy
  • Reinforced load-bearing areas to support long-term stacking
  • Integration with standard corrugated outer cartons

 

By maintaining the familiar geometry of thermocol endcaps while introducing engineered fibre structures, Honecore enabled a smooth transition with minimal operational disruption.

Validated Protection Performance

To ensure reliability in real logistics conditions, the packaging system underwent extensive validation.

Drop resistance

The patented design prevents product damage from drops of 500 mm, including impacts on:

  • Flat surfaces
  • Edges
  • Corners

 

This ensures protection during typical warehouse handling incidents.

Long-term stacking

The system has been proven to withstand stacking loads for more than 12 months without structural degradation.

This is critical for distribution environments where products remain palletised for extended storage periods.

Clamp lift handling

The packaging is validated for clamp lift handling, allowing units to be moved efficiently in large warehouse operations.

It supports stacking configurations of 1 + 10 units, maintaining structural stability under load.

Environmental Reliability

Distribution conditions are not always controlled.

Packaging must remain stable across extreme environmental conditions encountered during storage and transport.

Honecore’s system has been tested and proven to perform under:

  • Temperatures up to 75°C
  • Relative humidity levels of 90%

 

This ensures consistent performance across diverse logistics environments, including hot and humid climates.

Logistics Efficiency Through Smarter Packaging

One of the major advantages of the redesigned packaging system was improved space efficiency.

The engineered structure allowed the manufacturer to reduce the overall carton size without compromising protection.

This resulted in:

  • Lower material consumption
  • Improved container utilisation
  • Reduced transportation cost per unit

 

In high-volume distribution networks, even small reductions in packaging dimensions produce significant operational savings.

The Outcome

By partnering with Honecore, the manufacturer achieved a packaging system aligned with the realities of large-scale distribution.

The solution delivered:

  • Drop protection from 500 mm on all surfaces, edges, and corners
  • Proven 12+ month stacking stability
  • Compatibility with clamp lift handling and 1+10 stacking
  • Reliable performance under 75°C and 90% RH conditions
  • Reduced carton dimensions and improved logistics efficiency
  • Seamless transition from thermocol packaging with minimal operational change

 

The packaging system maintained operational familiarity while introducing engineered structural protection.

For high-volume manufacturing environments, that combination ensures reliability without disrupting production or distribution workflows.
