The pin‑type cold‑feed extruder is a next‑generation extruder that emerged in the 1980s. Since its introduction, it has become the successor to conventional rubber cold‑feed extruders. Compared with standard cold‑feed extruders, it offers superior extrusion capacity, excellent extrusion quality, reduced energy consumption, lower die‑temperatures, and greater versatility, making it suitable for processing compounds with diverse properties. It also features self‑cleaning capabilities, easy material changes, convenient control of process parameters, stable extrusion, and user‑friendly operation. In contrast to traditional hot‑feed extrusion processes, it eliminates the need for thermal mixing, resulting in a smaller footprint, lower capital investment, and reduced operator requirements.
The pin‑type cold‑feed extruder is a next‑generation extruder that emerged in the 1980s. Since its introduction, it has become the successor to conventional rubber cold‑feed extruders. Compared with standard cold‑feed extruders, the pin‑type cold‑feed extruder boasts superior extrusion capacity.
It boasts advantages such as high output, excellent extrusion performance, low energy consumption, reduced extrudate temperature, and strong versatility, making it suitable for processing compounds with varying properties. Additionally, it features superior self‑cleaning capabilities, convenient material changes, easy control of process parameters during extrusion, stable extrusion, and user‑friendly operation.
Compared with the conventional hot‑feed extrusion process, this method eliminates the need for thermal refining and offers advantages such as a smaller footprint, lower capital investment, reduced operator requirements, and more advanced process parameters.
Consequently, as soon as this type of extruder was introduced, it immediately attracted the attention of rubber manufacturers. Today, approximately 70 percent of extruders used abroad are screw‑type cold‑feed extruders. Thanks to their numerous advantageous features, the cold‑feed process is gaining widespread adoption; these extruders not only can replace hot‑feed extruders but also serve as sources of compounded rubber for calendering. Moreover, in certain applications they can even directly substitute for calendering operations, such as in the production of tire cushion layers, airtight layers, and profiled rubber parts.
Applications of the pin‑type cold‑feed extruder: It is used to extrude rubber semi‑finished products such as tire treads, sidewalls, inner tubes, hoses, and sealing strips, as well as for cable jacketing and supplying rubber stock to calenders.
Applications of standard cold-feed extruders: primarily used for extruding various types of automotive hoses, reinforced hoses, and profiled hoses; for extruding a range of small and medium-sized industrial hoses; and for extruding textile roller covers and rubber rings, among other applications.
The equipment comprises a motor, a reducer, a feeding device, a screw in the料筒, a die head, a temperature control system, an electrical control system, and a frame, among other components.
