One of our customers in Germany required a pre-roll filling machine for 1.0 g cannabis pre-roll production, with consistent filling weight and practical production capacity as the key requirements.
The 1g pre-roll filling machine supplied by HiURTB was manufactured and tested before shipment, then delivered to Germany for installation and commissioning.
Under actual production conditions, the system achieved 700–800 pre-rolls per hour, with 1.0 g pre-rolls controlled within approximately 0.95–1.05 g.
Project Requirements
| Item | Project Specification |
| Application | Cannabis Pre-Roll Filling |
| Customer Location | Germany |
| Target Filling Weight | 1.0 g |
| Filling Accuracy | Less than 10% |
| Main Requirement | Consistent filling and stable production |
Machine Manufacturing & Pre-Shipment Testing
Based on our customer’s 1.0 g pre-roll specifications, our 1g pre-roll filling machine was configured and adjusted before shipment.
Pre-shipment testing was carried out with similar filling material and pre-roll cones to verify the filling process, machine operation and basic production performance.
Packing & Shipment to Germany
After pre-shipment testing and machine preparation, the machine was protected and packed in export wooden cases for delivery to the customer’s facility in Germany.
On-Site Installation & Commissioning in Germany
After the pre-roll machine arrived in Germany, our engineer carried out on-site installation, commissioning and production setup at our customer’s facility.
Our engineer then adjusted cone filling machine parameters according to the customer’s actual cannabis flower, pre-roll cones and target filling weight before production.
1g Pre-Roll Production in Germany
After commissioning, the 1g pre-roll filling machine was put into production using the customer’s actual cannabis flower and pre-roll cones.
The video below shows the pre-roll filling machine operating under actual production conditions at our customer’s facility in Germany.
Actual Production Results
| Performance | Actual Result |
| Target Weight | 1.0 g |
| Actual Weight Range | 0.95–1.05 g |
| Filling Tolerance | Within ±5% |
| Production Capacity | 700–800 pcs/hour |
| Material | Cannabis flower |
| Test Condition | Customer-site production in Germany |
Balancing Filling Accuracy and Production Speed
The 0.95–1.05 g filling range shown in this project reflects the operating settings selected for our customer’s 1.0 g pre-roll production.
The achievable filling range may vary depending on the material characteristics, machine settings and production speed.
Filling accuracy and production speed can be balanced by optimizing the dosing parameters and operating settings.
When tighter weight control is required, the parameters can be further adjusted, although this may reduce production throughput.
Material characteristics—including particle size, moisture content, density and flowability-also influence filling consistency.
For this reason, final parameters are best optimized with your actual material and pre-roll cones.

Need a Pre-Roll Machine Solution?
Every pre-roll project is different. Pre-roll size, target filling weight, flower characteristics and required production capacity all affect the machine configuration and operating parameters.
Tell us your pre-roll specifications and production target, and we can recommend the appropriate machine configuration, conduct pre-shipment testing, and fine-tune the operating parameters based on your actual material and pre-roll cones during commissioning.
