Durable MM60 SK Screw Element for Twin Screw Extruders Ideal for Chemical Mixing
Product Description
The SK Screw Element is treated with polishing or sandblasting to ensure that its surface is smooth and free from imperfections. This process enhances the wear-resistance of the product, making it highly durable and long-lasting. Additionally, it undergoes a vacuum hardening heat treatment process that further improves its strength and resistance to wear and tear.
The SK Screw Element features a spline connection method that allows for easy and secure installation. This makes it easy to use and maintain, saving you time and money in the long run.

Quality Control
1). Materials control: All the materials are purchased from the domestic brands or European twin-screw specialty materials suppliers, which tested by elemental analysis and metallurgical inspections to ensure the quality.
2). The internal splines are 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 foreign brands.
5). Professional 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 fixtures 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.

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.
