PA612 is a special engineering plastic with higher thermal stability, dimensional stability and mechanical properties
It can be used to manufacture all kinds of auto parts which require high impact strength

Can be used for high toughness and good tensile ability of wire and cable coating, sealing strip and all kinds of pipeline products
Also can be used for high wear resistance and tensile requirements of daily silk and abrasive silk and other products


My company is high-tech enterprise in shandong, China, which mainly produces long carbon chain nylon.
The main products include nylon 610, nylon 612, nylon 1010, nylon 1012, nylon 1212,
transparent nylon and high temperature nylon, exported to Korea, the United States, Germany, Japan,
Turkey and other countries, and with many foreign customers to establish close cooperation.







Our ompany has the domestic advanced product inspection equipment, and passed the ISO9001 international quality management system certification, ISO14001 international environmental management system certification, products also passed the REACH, SGS,ROHS, FDA, MSDS and other related certification and testing.


My company's products have good comprehensive performance, a wide range of USES, can replace metal in the mechanical, chemical, instrumentation, automotive and other industries.And the product in the melt spinning, with higher strength, so it can be made into knitwear or blended into wear-resistant clothing materials.

1.What are the characteristics of nylon shrinkage?

 

Similar to other crystalline plastics, nylon resin shrinkage rate larger problems, the maximum nylon with crystallization of contraction, when products crystallinity big products shrinkage increases, in the process of forming lower mold temperature increasing injection pressure to lower temperature will reduce shrinkage, but the internal stress of products is more easy to deformation. For example of glass fiber reinforced PA6 and PA66 shrinkage rate at 1.5 to 2%, after joining the glass fiber can make the shrinkage rate reduced to 0.3% ~ 0.8%.

 

2.What is the temperature of the cylinder when nylon is injected?

Because nylon is a crystalline polymer, so the melting point is obvious, nylon resin in the injection molding of the selection of the barrel temperature with the resin itself performance, equipment, product shape factors.

 

Too high material temperature is easy to make the rubber parts appear color change, brittle and silver wire, and too low material temperature makes the material very hard may damage the mold and screw.Generally, the melt temperature of nylon 6 is as low as 220ºC, while that of nylon 66 is 260ºC.Due to the poor thermal stability of nylon, so should not be high temperature for a long time to stay in the cylinder, so as to avoid causing the material discoloration and yellow, at the same time because of the fluidity of nylon is good, the temperature exceeds its melting point will flow quickly.
