When it comes to extruding EPDM products, rubber extruders play a crucial role. Common items such as door and window sealing strips, cabinet seals, and rubber hoses all rely on rubber extruders. But how much do you really know about these machines? Let’s take a closer look at the extrusion process in rubber‑processing equipment. On an EPDM production line, the extrusion stage is where the rubber extruder’s function becomes especially critical, involving factors like machine stability, extrusion output, and energy efficiency. This also highlights that extruder configurations and performance can vary significantly. Just over a decade ago, most users relied on hot‑feed rubber extruders.
When it comes to extruding EPDM products, rubber extruders play a crucial role. Common items such as door and window sealing strips, cabinet seals, and rubber hoses all rely on rubber extruders. But how much do you really know about these machines? Let’s now take a closer look at the extrusion process in rubber‑processing equipment.
On an EPDM production line, starting from the extrusion stage, the rubber extruder plays a crucial role, as it directly impacts factors such as extruder stability, extrusion output, and energy efficiency. This also highlights that rubber extruders vary significantly in their configuration and performance. A decade or so ago, manufacturers relied on hot‑feed rubber extruders, which offered high throughput but suffered from operational instability and poor energy efficiency. Today, cold‑feed rubber extruders outperform their hot‑feed counterparts across multiple dimensions. For extrusion molding, the rubber extruder is indispensable. Weiyuan’s rubber extruders boast decades of proven success, with continuous equipment upgrades and ongoing R&D efforts. Whether measured by production stability or energy savings, these extruders deliver outstanding results.
The second step involves the stoning process for the product. For most standard products, a hot‑air stoning oven is sufficient; such ovens offer significant advantages in both efficiency and quality control. However, during stoning, a small amount of exhaust gas is generated, which must be collected and treated. Our company’s hot‑air stoning ovens are equipped with the corresponding ancillary systems to handle this.
The next steps are cooling and shaping, followed by traction. The sealing strips exiting the vulcanization chamber are at a very high temperature; for products that have just undergone vulcanization, their shape is not yet fully stable. Therefore, the subsequent process involves cooling, after which the cooled products are conveyed via traction to the packaging station, thereby completing the equipment’s role in the production process.
