Shaping the Future of Filament Extrusion
Over the last four decades, we have partnered closely with customers to understand their production goals and then engineer the right approach around those needs.
40+ Years of engineering expertise
Built on Experience. Proven Through Engineering.
For more than four decades, JJ Jenkins has built its reputation by solving demanding extrusion and fiber-processing challenges where standard equipment is rarely enough.
Founded in North Carolina in 1984, JJ Jenkins was built on a simple philosophy: understand the process, engineer the right solution, and stay involved long after the equipment leaves the factory. That philosophy continues to shape the company today.
From monofilament and slit-tape systems to specialized fiber-processing equipment, JJ Jenkins has continuously evolved its technology around the needs of demanding applications. The result is a depth of practical engineering expertise developed not only through design and engineering, but through decades of hands-on experience with materials, processes, machinery, and real-world production challenges.
Experience That Goes Beyond Equipment
The real legacy is not measured by the number of machines delivered, but by the process knowledge gained with every application. From polymer behavior and drawing conditions to thermal profiles and component integration, this expertise is built into every solution.
This experience spans monofilament, multifilament, slit tape, and specialty fiber processing, including medical, research, and pilot-scale extrusion systems.
From Specialist to Global Technology Platform
In 2024, JJ Jenkins became part of Leesona Corp., the U.S. subsidiary of Lohia Corp Limited, India, bringing its specialized extrusion expertise into a broader global technology platform.
Together, JJ Jenkins application-specific engineering expertise, Leesona’s U.S. presence, and Lohia’s global reach create a stronger platform for delivering proven technologies and specialized solutions to markets worldwide.
Every solution begins with your requirement
Material, process and performance define the solution. Our engineers evaluate each variable to deliver systems engineered around your specific application.
Material Evaluation
We begin by understanding the polymer and the functional demands of the end product.
- Polymer selection
- Melt behaviour analysis
- Material compatibility
Process Architecture
Critical process parameters are mapped into a complete extrusion system configuration.
- Thermal profile design
- Draw & cooling strategy
- Throughput optimisation
Precision Validation
Every critical variable is validated to achieve repeatable dimensional and mechanical performance.
- Tension & denier control
- Filament consistency
- Quality verification
Production Integration
We commission, optimise and support the system throughout its operational lifecycle.
- System commissioning
- Operator training
- FAT & commissioning
The people behind our continuous success
Technology defines capability. Experience defines application. Meet the team that brings JJ Jenkins’ knowledge and hands-on approach to every project.
Independent in expertise, stronger as a group
JJ Jenkins operates as a specialist engineering business, within Leesona and the Lohia Corp, combining complementary capabilities and global reach.
Operating in 100+ countries, Lohia Corp is a global engineering company delivering complete machinery solutions across extrusion, winding, weaving, coating, printing and conversion.
Founded in 1984, JJ Jenkins engineers custom extrusion systems for monofilament, multifilament, slit tape and medical-grade solutions through hands-on engineering and customer collaboration.
With a heritage dating back to 1893, Leesona is one of the world’s leading manufacturers of precision winding, take-up and rewinding systems for synthetic fibres and technical textiles.
