6. 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.
7. How to control the key processes of all the products we produced?
Processing range: φ 15.6- φ 500mm
High precision: It is completely processed according to the customer's drawings. Conventional components are processed after heat treatment to eliminate heat treatment deformation, so as to meet the customer's high-precision requirements.
100% full inspection: Each process should be self inspected by the staff first, and then 100% fully inspected by the inspector before delivery. The spline shall be 100% inspected by the spline plug gauge, and the material report and inspection report shall be provided during delivery.
Tolerance control range: The length shall be controlled within ± 0.01mm, The diameter tolerance shall be controlled within 0~-0.03mm.
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 produce the best products to match your application. Our shafts, barrels and screws are precision built to match your machine and performance. Each product is quality inspected for dimensional accuracy, straightness, and surface finishing.
8. Packing
To help prevent loss during shipping, we attach a copy of your packing slip not only to the outside of the box, but also to the part itself.
