01
Raw Material Check
Rubber compounds are tested by moving-die rheometer; EP fabric is checked for tensile strength and elongation to confirm belt strength and dimensional stability.
Quality control
Quality
Every order is checked against its requirements before packing and shipment.
Quality control
Checked before it reaches your site
Raw materials, in-process performance and finished belts are reviewed against each order’s requirements.

Evidence at every stage
02
In-Process Monitoring
A 4-roller calender applies rubber evenly while ply tension is controlled during forming to reduce wrinkles, uneven thickness and structural defects.
03
Finished Belt Inspection
Finished belts are checked for surface condition, length, width and thickness against order requirements before approval for packing.
04
Performance Testing
Laboratory testing covers abrasion resistance, adhesion strength, tensile strength and other data required by the order and applicable standards.
05
Final Review & Shipment
Each order is reviewed for specifications, appearance, dimensions, packaging and labels with reference to DIN, RMA, ISO and other standards.
