Screw elements are the main working parts for twin screw extruder which determined the quality and output of plastic products. With high quality, the screw elements assure plastic molecular mixing, cutting, spreading as well as reacting among themselves etc. Extremely high self cleaning performance assure the high quality of the whole production line, for this, our company combiend our experience for years, the merits about foreign countries and the customer's use,then take them into action, design and produce all kinds of suitable processing screw elements.
With a strong emphasis on producing only the highest quality with exceptional customer-oriented service, Joiner Machinery is able to provide a first-class service that is supportive to its global customers and strives to become a core extrusion parts and production enterprise with world influence.

4. Making process
5. 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 screw elements;
3). All components are machined by CNC machines to ensure the shapes and tolerances of screw 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
6. Heat treatment
As we all know, heat treatment is very important in the screw production process. In order to ensure the quality of screw elements, 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.
7. Production and Inspection of Equipment
We also have advantages in production equipment and inspection equipment.
Joiner has over100 advanced equipments such as CNC thread grinder, CNC thread milling, CNC kneading block grinder, CNC forming milling, 4-axis machining center, automatic deep hole grinder, CNC lathe, CNC surface grinder, CNC external grinding, CNC band saw, laser marking machine, vacuum quenching furnace and vacuum tempering furnace. After the raw materials enter the market, all the processing procedures are in-house.
