Wear resistant Corrosion resistant Compression Segments with Screw Diameter from 10mm to 300mm

Product Description:

The Compression Mixing Elements, Compression Compounding Elements, and Compression Pelletizing Elements undergo a rigorous treatment process of polishing and sandblasting. This treatment significantly improves the lifespan of the elements, reducing wear and tear, and prolonging the overall life of your equipment.

Our Compression Mixing Elements, Compression Compounding Elements, and Compression Pelletizing Elements are designed to be compatible with various types of equipment. These elements are suitable for use in a range of industries, including plastics, rubber, and chemical processing.

Investing in our Compression Elements translates to a significant improvement in your equipment's performance. Our Compression Mixing Elements are designed to mix a wide range of materials, including powders, pellets, and liquids. Our Compression Compounding Elements are perfect for compounding multiple materials, creating a homogeneous mixture. Our Compression Pelletizing Elements are designed to transform materials into pellets for easy handling and transportation.

Quality Control

1). Materials control: All the materials are purchased from the domestic brands or Eurpean twin-screw specialty materials suppliers,which tested by elemental analysis and metallurgical inspections to ensure the quality.

2). The internal splines is checked by the spline plug to ensure interchangeability of the elements

3). All components are machined by CNC machines to ensure the shapes and tolerances of the elements

4). Adopt the European high-speed steel powder processing technology,and do the treatment according to the strict heat treatment 4.process to ensure the wear and corrosion performance same as the foreigh brands.

5). Perfessioal technical team can not only provide timely and accurate mapping sample design but also the combination of elements of technical services.

6). There are various prepared technical information and the fitxtures for the various brands extruders to ensure the timely lead time.The common components have a lot of stock, even the new one, it can be delivered within 45days.

7). The modern management system can ensure the products 100% qualified and tracked.

Our Service

Product accuracy

There are some differences between Nanxiang Machinery and Nanjing's production technology. Their finishing process is carried out before heat treatment, and the deformation after heat treatment is not controlled, so their accuracy is not easy to control. But our finishing process is carried out after heat treatment, which can eliminate the deformation of parts in heat treatment, so the precision is higher, and thus can achieve zero seam connection.

Packing&Delivery

Packing Details: According to your order quantity packaging, shipping wooden boxes, air carton.

Delivery Details: 20-60days after order.
