Rubber extruder with gear pump for filtering contaminants from rubber compounds

A cold feed rubber strainer is a device designed to separate contaminations such as scrap iron and sawdust from your compounds. The rubber strainer utilizes a screw and gear pump system to feed the rubber in strip form at normal temperatures, then strain the compound. This filtering system is applicable for a variety of rubber compounds and is extensively utilized for the production of various rubber miscellaneous items, auto parts, seals, and oil seals.

Advantages

Gear pumps can be operated with a single drive or dual drive system.

Cold feed rubber strainer feed strip rubber compound at a normal temperature through a gear pump controlled strainer continuously.

Quick product setup with PLC control and process parameters database.

A separation structure using an electric motor supports the gear pump, screw and machine head, simplifying rubber raw material replacement and conducting easier cleaning.

Low temperature increase prevents scorching. Sulfur can be utilized optionally to avoid any potential risks.

Error alarm with an icon displaying fault location.

The searchlight is a useful tool for cleaning, helping to ensure that all those tricky, hard to reach spots don't get overlooked.

Both system and extrusion pressures are intuitively displayed on the touch screen.

When creating a prototype of a new product, having a PLC in operation provides useful data that can be used to streamline the process.
