Building a Siemens-Controlled Automatic Coffee Capsule Line for a Saudi Producer

A coffee producer in Saudi Arabia wanted to build a modern automatic capsule production system. The customer already had coffee formulas, packaging direction and local sales channels. As demand for capsule coffee continued to grow in the Middle East, the company needed a production line that could support higher volume, better consistency and more professional factory management.

The customer was not only buying equipment. They needed a matched system: automatic filling and sealing, stable control, suitable capsule packaging materials and branded printed roll film.

The Challenge

The customer required an international-grade control system and easier equipment management. Operators needed to monitor running status, adjust filling weight, control sealing temperature and manage production speed through a clear interface.

Filling accuracy was also important. For coffee capsules, small variations in fill weight can affect flavor, extraction and consumer experience. The line needed to dose coffee powder consistently while maintaining efficient production.

Packaging also had to match the equipment. The customer wanted aluminum coffee capsules for strong oxygen and moisture protection, plus custom printed roll film for brand presentation. If the capsule, film and machine are not matched, production stability can suffer.

ONWIN's Solution

ONWIN customized an automatic coffee capsule filling and sealing line based on the customer's requirements. The line was configured with Siemens PLC control and an HMI interface. Operators can monitor machine status and adjust key parameters such as filling weight, sealing temperature and production speed more conveniently.

The filling system was matched to the customer's coffee powder behavior. High-precision dosing helped keep each capsule within a stable fill range, supporting flavor consistency and batch control.

ONWIN also supplied aluminum capsule packaging. Aluminum capsules provide strong barrier performance, helping protect coffee aroma, reduce oxygen exposure and extend shelf-life. The capsules were matched with the automatic line to support smooth feeding, filling and sealing.

For brand presentation, ONWIN provided custom printed roll film. The roll film carried the customer's visual identity and product information, helping create a unified packaging system for retail.

The full line integrated automatic cup feeding, dosing, nitrogen flushing, sealing and finished product output. This reduced manual handling and created a stronger foundation for future capacity expansion.

The Result

After installation and commissioning, the customer's production line entered operation. With stable equipment performance, precise dosing and matched aluminum capsule materials, the customer was able to produce capsule coffee at commercial scale.

The project helped the company enter the capsule coffee segment in Saudi Arabia and surrounding Middle East markets with a more professional production setup.

Why This Case Matters

For coffee brands moving into capsule production, equipment alone is not enough. The control system, filling accuracy, capsule material, roll film and nitrogen process all affect final quality.

This case shows ONWIN's ability to deliver an integrated automatic line and the matching consumables needed for production. It also shows why customers planning long-term scale should consider both machine configuration and packaging material from the beginning.
