Covering more than 60,000 km², our manufacturing infrastructure is built for expansion and optimized to support large-volume, continuous production demands.
Topfloor's EPDM Granules Production Process
Raw Materials
Exceptional product quality begins with carefully selected imported raw materials. We source premium-grade rubber compounds from trusted international suppliers, with every batch undergoing strict in-house testing before being approved for storage and production.
Matching Accessories
Our fully automated, computer-controlled dosing systems ensure precise allocation of auxiliary materials. Accurate formulations guarantee color uniformity, stable performance, and consistent quality across every production batch.
Rubber Internal Mixers
Equipped with multiple high-performance rubber internal mixers, our facilities deliver efficient and stable mixing operations. This advanced equipment ensures smooth production workflows and guarantees on-time fulfillment of every order.
Squeezing
Our automated packaging system supports a wide variety of bag sizes and formats. With computerized weight control, each package achieves higher accuracy and consistency, reducing material loss and improving efficiency.
Cutting into Blocks
The material is precisely cut into uniform blocks, allowing complete and even vulcanization throughout the rubber during the curing process.
High-Temperature Vulcanization Oven
Using an advanced high-temperature vulcanization method, our process is environmentally friendly and energy efficient. Compared to traditional curing techniques, it delivers significantly enhanced vulcanization performance and product quality.
Cooling Process
A controlled cooling stage is applied to stabilize material properties, ensuring optimal performance and improving overall product uniformity.The material is precisely cut into uniform blocks, allowing complete and even vulcanization throughout the rubber during the curing process.
Granule Cutting
Once properly cooled, the material is processed into granules with consistent shape and size, maintaining stable quality throughout the batch.
Sieve Filtration
The granules are screened through multiple precision mesh filters. Oversized particles are automatically reprocessed via conveyor cutting to strictly meet customer size specifications. An integrated dust-removal system ensures the finished granules are clean and virtually dust-free.
Packaging
Our automated packing lines accommodate various bag types and sizes. Computer-controlled weight systems deliver precise measurements for consistent and accurate packaging.
Pallet Packing
Using fully automatic palletizing equipment, products are stacked efficiently and uniformly. This standardized process prevents pallet collapse and ensures stability during transportation.
Warehousing
After packaging, products are transferred by forklift to our dedicated warehouse facilities. With a total storage area of 25,000 square meters, we offer both indoor and outdoor warehousing to meet diverse customer requirements.
Loading & Delivery
Our experienced logistics team carefully loads and secures each shipment to maintain packaging integrity. Even after extended sea transportation, goods arrive neatly stacked and well protected.
