Twin Screw Heat Treated SK Screw Element for Enhanced Powder Feeding in Extrusion
The SK Screw Element for Discharging Section is a versatile product that can be used for a variety of functions. It is particularly effective when used as an SK Double-Head Conveying Screw. This product is designed to provide a high level of wear-resistance, which means that it is durable and long-lasting. Its high wear-resistance also ensures that it will perform reliably even in demanding environments.
The SK Screw Element for Volume Expansion is a product that is designed to help increase the volume of materials that are being conveyed. This product is particularly useful for applications where it is necessary to move large quantities of materials quickly and efficiently. The SK-01 model is ISO 9001 certified, which means that it meets high standards of quality and performance.

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.

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.
