1. Brief introduction:

2. Processing of making:



3. Factory introduction
Our factory is state-of-the art and spans over 20,000 square meters. The factory houses more than 165 sets of different domestic and foreign high precision production equipment, with the degree of numerical control up to 95%.



4. 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.

5. Quality Craftsmanship:
we believe there’s nothing more important than getting it right the first time! That’s why our team of engineering experts does whatever it takes to design the best products to match your application. Once the design is complete, our shafts, barrels and screws are precision built to provide you with the highest level of quality and performance possible. Each product is then quality inspected for dimensional accuracy, straightness, and surface finishing.

6. Types of screw elements we produce:

7. Quality Control:
a. 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.
b. The internal splines is checked by the spline plug to ensure interchangeability of the elements
c. All components are machined by CNC machines to ensure the shapes and tolerances of the elements
d. 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.
e. Perfessioal technical team can not only provide timely and accurate mapping sample design but also the combination of elements of technical services.
f. 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 60 days.
g. The modern management system can ensure the products 100% qualified and tracked
