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.

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.
Technics:
Heat treatment
Nitriding treatment
Hard-chrome electroplating
Bimetallic alloy welding
Bimetallic alloy centrifugal casting
6. Processing Route Tracking List
Each process requires inspection . The production personnel shall
check whether it’s meet the requirements of the drawings by
themself. If it meets the requirements of the drawings,it shall be
submitted to the inspection personnel for inspection. After pass
the inspection to the next process personnel processing.
7. 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.
