About KWLE
Engineering and manufacturing packaging systems for powders and granules
KWLE is an industrial packaging equipment manufacturer specializing in open-mouth bagging systems for powder and granular materials.
With more than 20 years of experience, we design and manufacture equipment for weighing, feeding, filling, bag handling and bag closing, as well as integrated packaging lines built around actual production requirements.
From individual machines to complete packaging lines, our systems are engineered according to the material, bag type, required capacity, closing method, plant layout and upstream and downstream processes.
What We Build
Open-mouth bagging equipment and integrated packaging lines
KWLE develops packaging systems for powders, granules and related bulk materials, covering applications from manual bagging to fully automatic packaging lines.
Bottom-Up Powder Filling Lines
KBF Series for powders requiring controlled filling, reduced filling height and effective dust management.
Manual Bagging Stations
Manual and semi-automatic solutions for applications where full automation is not required.
Weighing & Feeding Systems
Net weighing systems with gravity, belt or screw feeding configurations according to material characteristics.
FIBC Filling Systems
Filling systems for 500–1500 kg FIBC applications.
Integrated Packaging Lines
Integration of weighing, filling, bag closing, conveying and related downstream equipment into complete packaging systems.
Engineering, Manufacturing and Factory Testing
Designed, engineered, assembled and tested by KWLE
KWLE combines mechanical engineering, electrical and control engineering, equipment manufacturing, assembly, integration and factory testing within the same project process.
Each system is developed around the actual application rather than a fixed machine configuration. Material characteristics, bag specifications, required capacity, closing method, available plant space and equipment interfaces are considered during engineering.
Mechanical Engineering
Machine configuration, mechanisms, layout and equipment interfaces.
Electrical & Control Engineering
Control system design, PLC programming, drives, sensors and line coordination.
Manufacturing & Assembly
Equipment fabrication, assembly and complete machine integration.
Factory Testing
Functional testing and project-specific FAT before shipment.
More Than 20 Years of Packaging Experience
KWLE has accumulated more than two decades of practical experience in industrial bagging applications for powders and granular materials.
Our experience covers weighing, feeding, filling, bag handling, product deaeration, bag closing, conveying and downstream integration, from individual machines to complete packaging lines.
20+ Years
Industrial bagging equipment experience
Powders & Granules
Application-focused packaging engineering
Open-Mouth Bagging
From manual filling to fully automatic systems
Complete Lines
From weighing and filling to downstream integration
Built with Globally Supported Industrial Components
Industrial packaging equipment is expected to operate for many years. Maintainability and access to replacement components are therefore considered during system design.
KWLE uses established industrial automation, drive, electrical and pneumatic components according to project requirements, helping customers maintain equipment using widely supported technologies and replacement parts.
Component brands and specifications may vary according to project requirements and regional availability.
From Project Engineering to Lifecycle Support
A packaging project does not end when the machine leaves the factory. KWLE supports the project from technical clarification through engineering, manufacturing, testing, delivery and equipment operation.
