Raw Material Processing Know-How

With a modular equipment architecture and process parameter database, Weida’s natural rubber processing systems adapt to different regional feedstock forms and impurity levels, covering the full chain from pretreatment to finished product processing.

Processing of Fresh Latex and Coagulated Rubber

For feedstock forms such as fresh latex, naturally coagulated rubber, and primary rubber blocks, Weida configures dedicated sheeting, creping, and shredding units to deliver uniform size reduction and effective impurity separation, creating a stable foundation for downstream granulation and drying.

Processing of Cup Lump, Block Rubber, and Mixed Feedstock

For cup lump, block rubber, and mixed-grade feedstock with irregular shape and higher impurity levels, Weida uses adjustable crushing and squeezing-washing structures. By combining crushers, single-screw squeezing-washers, crepers, shredders, automatic discharge devices, and drying systems, we improve impurity removal and material homogeneity while maintaining throughput.

Adaptation to Multiple Process Routes

Depending on target product type and market standards, lines can be configured for:

• TSR standard rubber lines
• Crepe rubber lines
• RSS lines
• Compound and dry-mixing rubber lines
• Wet-mixing scrap rubber lines
• Raw rubber dewatering lines

This enables multi-product route compatibility within one expandable equipment framework and improves investment flexibility.

Adaptation Across Regional Feedstock Differences

For major producing regions including Africa, Southeast Asia, and South America, where moisture, sand content, bark ratio, and impurity composition differ significantly, Weida adjusts process parameters and equipment configuration to ensure stable processing capacity and consistent final quality under varied feedstock conditions.
