Good quality high wear resistance screw elements spare parts for twin screw extruder are components that are made of high-quality materials and designed to withstand the extreme conditions and stresses of the extrusion process. These parts are critical to the performance and longevity of your twin screw extruder.

Some examples of good quality, high wear resistance screw element spare parts include:

1. Screw elements - made from materials such as high-speed steel or tungsten carbide, these can be coated with wear-resistant materials to further enhance their durability.

2. Barrel liners - typically made from nitrided steel, ceramic, or bimetallic materials, these liners protect the barrel from wear caused by abrasive materials or high temperatures.

3. Feeding screws - designed to handle materials that are difficult to feed into the extruder, these screws have specialized designs that help prevent clogging or bridging.

4. Mixing elements - used to ensure thorough mixing of materials in the extruder, these elements are often made from specialized materials such as hardened tool steel or carbide.

In summary, good quality high wear resistance screw elements spare parts help improve the efficiency and reliability of your twin screw extruder, ensuring that it operates at peak performance for longer periods of time.

2 . The application of the extruder spare parts 

The application for parts of machinery for working rubber or plastics varies depending on the specific part and the machinery it is designed for. These parts are typically used in industrial settings, particularly in manufacturing processes that involve working with rubber or plastics materials. Some common applications include:

Injection molding: Parts such as molds, dies, and nozzles are used in injection molding machines to shape and form plastic or rubber materials into various products and components.

Extrusion: Extrusion machines use parts like screws, barrels, and dies to melt and shape plastic or rubber materials into continuous profiles, tubes, or sheets.

Blow molding: In blow molding processes, parts like molds and blow pins are used to create hollow plastic or rubber products, such as bottles or containers.

Calendering: Calender machines employ parts like rolls, knives, and guides to process rubber or plastic materials into sheets or films of desired thickness and texture.

Cutting and trimming: Parts like blades, cutters, and trimmers are utilized in machinery to precisely cut, trim, or shape rubber or plastic materials into specific dimensions or forms.

Mixing and compounding: Machinery parts such as mixing blades, rotors, and screws are employed in mixing and compounding processes to blend rubber or plastic materials with additives, colors, or fillers.

Recycling: Various parts are utilized in recycling machinery to shred, granulate, or pelletize rubber or plastic waste for reprocessing into new products or materials.

These applications represent a broad range of processes where parts of machinery for working rubber or plastics play a crucial role in shaping, forming, cutting, or processing these materials to meet specific industrial requirements.

3 . New Materials Introduction

Based on long years of experience for the manufacturing, in order to long last the service life of the liner or barrel liner, we developed our special new materials OS02H , a kind of Nickel-Chromium- Tungsten alloy.

Nickel-Chromium- Tungsten alloy has excellent abrasion resistance and corrosion resistance. The increase of Cr content in the nickel-chromium alloy matrix contributes to the oxidation resistance, high temperature resistance and corrosion resistance of the alloy. At the same time, the addition of CrB is better than WC. The microhardness of CrB is as high as 4000-4200DPH, which is close to diamond. It is more conducive to improving the overall strength of the alloy. Due to the high density of WC, it is about 15.7g/cm3, while the matrix of nickel-chromium alloy is only about 8g/cm3. The melting is caused by the uneven surface and depth of the alloy due to the easy segregation of WC, so the content and particle size of WC must be controlled.

Nickel-Chromium-Tungsten alloy( we call OS 02H) hard phase increased to about 50%, OS02 is only ten to thirty,Moreover, the fusion is not sufficient, and the microscopic pores are relatively obvious, which is reflected by the Rockwell hardness HRC of only 52-55.While the Rockwell hardness of nickel chromium tungsten alloy (OS02H) is HRC56-64, the conventional control is HRC58-60. The service life is 3-5 times longer then WR5 or CPM10V.

Nickel-Chromium-Tungsten alloy( OS02H )on the basis of Ni60 in accordance with foreign twin screw working conditions of the formula, greatly improved Hard phase carbides (containing tungsten carbide chromium carbide and other carbides), and the nickel pool fullDissolve. Our Ni-Cr -W alloy layer can reach HRC64 is the best proof.

4 . Liner Types

Single metal liner,

Bimetallic compound liner,

Sintered process composite liner

spray welding process composite liner

5 . Bimetallic Compound Liner Features:

Material Parameters Temperature Resistance:

Temperature limit 600℃

Alloy Layer Thickness: ≧1.8mm

Alloy Layer Hardness: 57-64HRC

The Main Process Is Different (from the original sintering process to the current spray welding process) The product has better densification, the hardness can reach more than 57 degrees, and the service life of the product is 3-5 times that of the sintering process.

6 . Main Brands Extruder for using the Liner

7 . Production Equipments
At present, the company’s factory area exceeds 3000 square meters, and an additional 3000 square meters are under planning and design, covering the complete production process of material research and development, main component production, and testing. The company has 6 technical person,over 40 workers, and multiple imported production and testing equipment from Taiwan and Germany.

8 . Quality Control

The Test Equipments we have now are as follows:
three coordinate detectors, dimensional image measuring instruments, metallographic analyzer, ultrasonic flaw detector, element analyzer and many other basic test machines. Which can fully confirm the quality we offered.

9 . Our Advantage
