PP granule material is not similar other plasitcs. It needs special screw to process the granule.
Ningbo Jinyi not only focus on injection mold machine screw,but also focus on extrusion blowing mold machine screw.
Our advantages as below:
5 foctories. Except raw material is outsource.We manufacture all aspects by ourselfes.
They are injection mold machine screw and barrel factories; accessories factory:like screw tips,adapter,thrust rigng,sealing elements, strainer and others; tie bars factory; electroplating factory; extrusion and blowing mold machine screw and barrel factory with conical twin screw barrel and parrel twin screw barrel.
-
- More than 30 pcs NC and CNC machine center which can machine all aspects of products.
- Nitriding workshop with 5 ovens. We can nitride the raw material with more than 50 Tons totally one time by computer control system.
- Centrifugal casting workshop. We imported centrifugal casting equipment, which can produce various Fe-based,Ni-based&Co-based bimetallic barrels as per requirement.
- PTA bimetallic spraying workshop which not only can improve the effiency & bimetallic precision, but also can improve the anti-abration and anti-crossion of producs.
- Laboratory has all kinds of testing equipment. Like rockwell hardness tester,coordinate measuring machining,bruker spectrometer and metallographic microscope.
- Electroplating work shop can electroplate customized type,like chromium,TiN,CrN,AlTiN and tungsten carbide.
- Around 350 experienced workers in every manufacturing procedure.
- More than 6 engineers who can support us drawing,designing and technology.
- Strong ERP system with all kinds of injection machine,extrusion machine,blowing machine and die casting machine's spare parts drawing. It is easy for us to recommend your ideal drawing.
- 4 after-sale service people,suppose there is needing technical support. They can answer you in first time.
- Capability: 5000TONS per month;60,000TONS per year.
- Turnover: USD 30 million.
- Strong execution by our team.
- Learning Inamori Kazuo master's business philosophy day by day. Working during learning,learning during work.
Our hope is to be the No. 1 plastic machine screw and barrel factory in the world.
Hope we can find a way to cooperate with each other on mutual benefits and development.
