Product introduction

Zhoushan durable rubber screw price is a basic equipment of the rubber industry, is one of the key equipment affecting product quality, plays a very important role in the production process of tires and rubber products. The development of foreign rubber extruders has experienced plunger-type extruder, screw-type hot-feed extruder, ordinary cold-feed extruder, main and auxiliary thread cold-feed extruder, cold-feed exhaust extrusion Machine, pin cold feed extruder, compound extruder and other stages.

Detailed introduction

Zhoushan durable rubber screw price technical indicators:
Quenched and tempered hardness: HB240-280
Nitriding hardness: Hv950-1020
Nitrided layer depth: 0.45-0.8mn
Nitriding brittleness: ≤ secondary
Surface roughness: Ra0.4um
Screw straightness: 0.015mm
Chrome surface hardness after nitriding: ≥950Hv
Chrome plating thickness: 0.05 ~ 0.10mm
Double alloy hardness: HRC58-65
Double alloy depth: 0.8-2.0mm
Screw diameter: PX-Φ65 / 2-Φ150 / 2
L / D ratio: L / D = 18-30
Screw compression ratio can be designed according to different raw materials and different products. Extruder screws and barrels can be used.
Zhoushan durable rubber screw price range:
1. Brand screw barrels: Haitian injection molding machine screw barrels, Zhenxiong injection molding machine screw barrels, etc .;
2. Screw barrels for various extruders: Customized screw barrel sets for sheet, pipe, and profile extruders;
3. Special screw barrels for various film blowing machines and rubber machines;
4. Special screw barrels for various injection molding materials: PA nylon material, PMMA acrylic material (plexiglass), EPS foam plastic
The advantage of this product is that it has a compact structure, improves the overall performance and stability, improves production efficiency, and ensures the quality of film products. In addition, it can ensure the position accuracy of each component and avoid position changes caused by disassembly.
Aspect ratio: The aspect ratio of the screw is the ratio of the length L of the screw to the diameter D of the screw. The screw has a large length-to-diameter ratio, that is, the screw has a long working part, and the rubber material is plasticized and mixed uniformly. The rubber material is under high pressure and the product quality is good. However, the length of the screw can easily cause scorching of the rubber compound, which makes the screw processing difficult and increases the extrusion power. The screw used for hot-feeding extruder is generally 4 to 6 times longer, and the screw used for cold-feeding extruder is generally 8 to 12 times longer.
