Cold-feed extruder series

Application: It is used to extrude various types of tire tread, sidewall, apex and other components, as well as for extruding rubber for calendering process.

1. Optimized design of screw, barrel, can satisfy user's of various need of designs, formulations and process.

2. Constant temperature and pressure extrusion ensure a stable extrusion quality.

3. Digital Speed control system is accurate and reliable, and with maintenance exemption.

4. With different handpiece, can achieve material feeding, film or tubes extrusion,etc.

1.Multi-stage temperature control: The barrel consists of plastication stage and extruding stage , and each section is able to control the temperature with temperature control device.The barrel is drilled with a temperature-controlled water hole channel along the circumference to facilitate heat exchange between the temperature-controlled water and the barrel.

2.High-quality screw and barrel: They are made of alloy steel 38CrMoAlA , and its surface is nitrided. The surface hardness of the screw is ≥ HV900, and the surface hardness of the barrel is ≥ HV950.

3.Hardened reducer: The transmission adopts hardened cylindrical gear , which is made of high-hardness alloy steel material by grinding, ensuring stable transmission, low noise and small volume.
