Product Description

 Application: Injection molding machine.
Injection material:amorphous polycarbonate(PC).
PC characteristic: Commonly it can be with color powder or without. Fusing point:220-230ºC.Drying temperature:100-120ºC. Drying time: 4H;poor liquidity;Thermal stability is good. Forming temperature:260-310ºC. PC is widely used on optical;vicel light;glass;drinking bucket and copmuter spare parts and so on.
We recommend PC screw with two material. Economical material is JIS(SCM440)=USD(4110)=Germany(1.7225). 
Processing draf(mainly):1.adjust the quality's hardness up to HB250-280. 2: electroplating after quenching(>=3mm;45-50HRC);Polishing;electroplating thickness>=0.05mm;hardness >=850HV. More important thing: Don't quench the connecting thread and end face. 

Another top quality material is secret,if you make order,we can show it to you.
Processing draf(mainly):1.adjust the quality's hardness up to HB260-280. 2: quenching(>=3mm;58-60HRC); Especially for installation axle head must be quenched,hardness <=42HRC,polishing.


Note,whatever you are choosing the material. You have to pay attention to the ponits. 1:structure of flight. 2:exhaust effect 3:plastic temperature and solute. 4:rate of L/D  and  compression ratio 5:If screw outside diameter is less than 35, we just you choose top quality material. 6: pay attention to the platicizing pressure.

Why choosing JINYI,our advantages as below:

1. 5 foctories. Except raw material is outsource.We manufacture all aspects by ourselfes.
2. More than 20 pcs CNC machine center which can machine all aspects of products.
3. Nitriding workshop with 5 ovens. We can nitride the raw material with more than 50 Tons totally one time by computer control system
4. Centrifugal casting workshop. We imported centrifugal casting equipment, which can produce various Fe-based,Ni-based&Co-based bimetallic barrels as per requirement.
5. 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.
6. Laboratory has all kinds of testing equipment. Like rockwell hardness tester,coordinate measuring machining,bruker spectrometer and metallographic microscope.
7. Plating work shop can plate customized type,like chromium,TiN,CrN,AlTiN and tungsten carbide.
8. Around 350 experienced workers in every manufacturing procedure.
9. More than 6 engineers who can support us drawing,designing and technology.
10. Stron ERP system with all kinds of injection machine,extrusion machine and die casting machine's parts drawing. It is easy for us to recommend your ideal drawing.
11. 4 after-sale service people,suppose there is needing technical support. They can answer you in first time.
12. Capability: 5000TONS per month;60,000TONS per year.
13. Turnover: USD 30 million.
