Production Methods,
and Quality Control
Every Fenner Dunlop conveyor belt is engineered, manufactured, and tested in our Dutch facilities under the strictest European quality standards. From raw materials to final inspection, we maintain total control over every stage of production - ensuring long service life, operational safety, and full compliance with ISO, REACH, and other international regulations.
-
1. Raw Materials
We use REACH-compliant rubber compounds. high-strength fabrics. and steel cords from certified suppliers. Each batch is tested to guarantee uniform quality and traceability.
-
2. Mixing & Preperation
Rubber is mixed in computer-controlled systems for perfect ingredient dispersion and adhesion. Our in-house formulations deliver targeted resistance to heat, fire, oil, or abrasion.
-
3. Calendering & Carcass
Building The compound is calendered onto textile or steel reinforcements, forming the belt carcass. Precise tension and alignment ensure consistent thickness and bonding strength.
-
4. Vulcanization
Under controlled temperature and pressure, each belt is vulcanized to permanently bond all layers - giving it strength, flexibility, and uniform physical properties across its length.
-
5. Final Inspection & Testing
Every belt is visually and mechanically tested for tensile strength, adhesion, elongation, and dimensional accuracy before dispatch. All data is recorded for full product traceability.
