Factory Overview

Built Around Heavy-Duty Belt Production

Founded in 2008, our manufacturing base covers an area of 58,000 square meters with complete production lines for rubber conveyor belts. We have a professional team including rubber formula R&D engineers, production technicians and QC inspectors.

We focus on heavy industry bulk conveying solutions, deeply understanding harsh working environments such as high temperature, sharp ore impact, heavy abrasion and continuous 24h operation.

Production Workshops

Full-Process Production, All Under One Roof

We own full-process production workshops from raw rubber compounding to finished belt inspection and packaging.

Rubber Compounding Workshop

Raw rubber, carbon black, antioxidants and other additives are proportioned and mixed here. Custom rubber formulas are developed here to meet requirements of heat resistance, wear resistance, tear resistance or oil resistance for different site conditions.

Calendaring & Fabric Impregnation Workshop

Textile canvas or steel cord materials go through dipping and calendaring. This step ensures strong bonding between carcass and rubber cover, preventing delamination under long-time heavy load.

Vulcanization Workshop

Vulcanization is the core procedure for conveyor belt production. Under controlled temperature and pressure, the rubber forms stable physical properties to resist abrasion, impact and aging. Our continuous vulcanizing equipment guarantees consistent quality for long-length belts.

Cutting & Finishing Workshop

Finished belts are cut into required widths and lengths. Edge trimming, surface cleaning and marking are completed here according to order specifications.

Raw Materials Warehouse

A dedicated warehouse stores raw rubber, SBR, carbon black and fabric carcass in a dry, shaded and well-organized environment. Proper material storage keeps compounds clean and stable, which directly supports consistent belt quality and shorter production lead time.

Quality Control

Quality Control & Laboratory

Quality is the top priority for heavy-duty conveyor belts, especially for mining and cement plant projects where belt failure may cause costly downtime.

Our QC process runs through the whole production flow:

Raw material incoming inspection: test rubber, canvas and steel cord before entering production
In-line production inspection: regular sampling during compounding, calendaring and vulcanization
Finished product full inspection: dimension check, surface visual inspection and lab performance test
Delivery inspection: random sampling before packing and loading

We can provide test reports according to ASTM or ISO standards. All products can be inspected by third-party organizations such as SGS and BV upon client request.

Certifications: ISO 9001 Quality Management System, SGS test certificates, factory audit support.
