Establish Uncompromising Quality Standards

From careful selection of high-quality raw materials to strict quality control inspections, no detail is overlooked.
Raw Material Preparation
Raw Material  
We use high-quality raw materials with consistent performance, and carefully select, wash, dry, cut and other processes to achieve the required length and purity to ensure the production of high-performance glass fiber roving.
Packaging With Pallet
 Packaging With Pallet
 
For large quantities of yarn we use pallet packaging where the wound yarn packages are stacked and arranged on wooden or plastic pallets for stability and to minimize the risk of yarn damage during loading, unloading and transport.
 
Fiber Drawing
Fiber Drawing 
During this process, we use advanced fiber drawing technology and machinery to heat the glass to a molten state and then stretch it into fine continuous filaments, precisely controlling the fiber diameter and tensile strength to ensure its uniformity and strength.
Plastic Packaging
 Plastic Packaging
 
After the yarn is wound on the spool, it is usually wrapped in a plastic bag or sleeve for protection, which helps protect the yarn from dust, moisture and other contaminants during storage and transport.
 
Fiber Coating
Fiber Coating  
Once the fiber is drawn, it is coated with various materials to enhance its performance and handling characteristics, help protect the fiber during subsequent processing steps, and improve its compatibility with the matrix material in composite applications.
Yarn Coiling
 Yarn Coiling
 
At this stage, we employ automated yarn winding equipment to ensure that the yarn is wound onto spools or bobbins precisely, consistently and evenly, often in a specific pattern or arrangement to facilitate handling and further processing.
 
Fiber Forming
Fiber Forming  
Once the fibers are coated, they are gathered and assembled into bundles called rovings, using state-of-the-art fiber forming techniques to ensure consistent fiber alignment and distribution throughout the roving.
Drying
Drying 
Once the roving is formed, it passes through a heated chamber or oven where controlled temperature and airflow ensure thorough drying, we implement precise drying parameters to maintain fiber integrity and minimize the risk of defects.
Operating in 126 countries and supplying the highest quality materials to over 1000 customers worldwide, we value the trust you place in us and are committed to helping you succeed.
