1.Company introduction

 

The company was built in 2007 with a registered capital of RMB 15 million, covering an area of more than 20000 square meters and 148 employees, including 12 engineering and technical personnel, 6 quality management personnel and 9 production management personnel. 
 

In the past 16 years, with the rapid development of the domestic machine tool industry, China's manufacturing capacity has made significant progress. At present, the finishing process has fully realized numerical control processing, and has been very mature in the production of detection means and special fixtures.

2.  How to control the key processes of all the products we produced?
 

-- Barrel

Water channel layout (ultrasonic detection preliminary judgment of water channel layout - water in the water channel to determine the weight of water to calculate the volume of the water channel, to determine whether the water channel is consistent with the original design)
 

-- Shaft

Only the surface roughness is slightly different from that of Germany, which, like Japan, does not affect the use; (At present, only spline milling can solve this roughness problem).The bearing torque coefficient of the shaft is calculated accurately by the calculation formula of torque, so as to ensure the bearing torque and strength
 

-- Screw element

Processing accuracy is not lower than the European level

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.



3. Materials:

Material: All materials purchase from domestic first-line brands or European twin-screw plastic machine professional material suppliers. After coming to the factory, the materials will be subject to chemical composition and metallographic analysis and inspection to ensure the quility.

For wear application:

Tool steel: W6Mo5Cr4V2

PM-HIP materials: SAM10, SAM26, SAM39, CPM 10V,CPM9V.

For corrosion application:

Nitrided steel: 38CrMoAl

PM-HIP materials: WR4, SAM26, SAM39, CPM 10V,CPM9V.

For wear and corrosion application:

PM-HIP materials: SAM26, SAM39, CPM 10V,CPM9V

Other materials:

304, 316L, C276 etc.

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. 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.

   According to your order quantities and products sizes to choose wooden boxes or cartons to pack:
a. Rust-proof oil processing,
b. Oiled paper packages,
c. Bubble wrap package,
d. Special foam packaging,
e. Packing,
f. Sealing.
