2. About equipment
3. Materials for choosing:
1). For wear application:
Tool Steel : W6Mo5Cr4V2;
PM-HIP material : SAM10 SAM26 SAM39 CPM10V CPM9V
2). For corrision application:
Nitrided Steel: 38CrMoAI;
PM-HIP material : SAM26 SAM39 CPM10V CPM9V
3). For wear and corrision application:
PM-HIP material:SAM26 SAM39 CPM10V CPM9V
4). Other Materials:
Stainless Steel: 316L, C276 etc.
4.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 spines 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 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
5. Heat treatment:
As we all know, heat treatment is very important in the screw production process. In order to ensure the quality of products, Joiner has purchased professional heat treatment equipment to produce, so that we can control the construction process by ourselves. In China, we are the only company that does heat treatment by ourselves, and the heat treatment of screw components made by Nanjing factory is processed by outsiders, so the quality of products can not be completely guarantee.
6. Product accuracy:
There are some differences between Joiner 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.
7. Packing:
Packing Details: Standard packing for Joiner Extruder twin screw extruder parts/extruder spare parts.
To product antirust processing, and then use the paper package, bubble, fixed in the wooden case, after confirm the delivery.
