Project Snapshot

The Challenge

The client is a global contract manufacturer serving leading consumer goods brands in the Air Care and Home Care segments. They needed to build a dedicated fragrance granule filling line at their U.S. facility. Three requirements defined the scope:

1. Difficult material characteristics Fragrance granules have poor flowability and tend to bridge and block at the discharge point, causing inconsistent fill weights and frequent stoppages — a common challenge that standard granule filling equipment is not designed to handle.

2. Space and workflow constraints The existing workshop had a fixed footprint. The new line had to integrate cleanly into the facility without disrupting existing upstream and downstream operations or creating floor traffic bottlenecks.

3. Full-process technical coordination The client needed a supplier who could take ownership across all phases — from layout planning and equipment build through to on-site commissioning and production ramp-up — rather than delivering equipment and stepping away.

Our Solution

1. Production Line Layout Optimization

Before specifying any equipment, LWT's team analyzed the full workshop material flow and proposed a line arrangement that minimized internal transport distance, eliminated cross-traffic, and made efficient use of the available floor area. This upfront planning reduced the risk of costly layout changes after installation.

2. Custom Filling System for Poor-Flowability Granules

The filling machine was adapted specifically for fragrance granule characteristics. The key modification was a redesigned discharge structure to prevent material bridging and blockage at the hopper outlet, ensuring consistent fill weights and uninterrupted line operation. Fill accuracy and material loss reduction were the primary engineering targets.

3. Full-Cycle Project Service

LWT took responsibility across the entire project lifecycle:

This end-to-end model shortened the client's time-to-production and reduced trial-production costs — both critical for a contract manufacturer operating to brand-owner delivery schedules.

Results

• Stable production output achieved on schedule
• Material bridging issue resolved through the customized discharge design
• Workshop layout integrated without disruption to existing operations
• Full-cycle service reduced the client's internal coordination burden across project phases

FAQ

Q: Can LWT supply a complete turnkey fragrance granule filling line? 

A: Yes — from bag-breaking and filling through capping, case packing, and conveying, all integrated and tested before shipment.

Q: How do you handle fragrance granules with poor flowability? 

A: We adapt the discharge structure and hopper design specifically for the material. The solution is validated during the equipment design phase, not worked out during commissioning.

Q: Do you provide on-site commissioning for overseas projects? 

A: Yes. LWT engineers travel to client facilities for installation, commissioning, and operator training. This is included in our standard full-service project scope.
