Because of its variety, the melting temperature is within the range of 300~425 C. The viscosity of LCP melt is low, the fluidity is good, and it is similar to the olefin plastic. LCP has a very small coefficient of linear expansion and a good dimensional stability. The forming processing conditions are as follows: molding temperature 300~390 C, mould temperature 100~260 C, molding pressure 7~100MPa, compression ratio 2.5~4, and molding shrinkage rate 0.1~0.6. 1. barrel temperature Generally, the temperature of the barrel, the temperature of the nozzle and the melting temperature of the material are shown as shown in the table. If the service life of the screw is taken into account, the temperature difference between the rear, the middle and the front can be reduced. In order to prevent the nozzle salivation, nozzle temperature than shown in the table of the low temperature of 10 DEG C, if you want to improve the liquidity, the temperature can be shown in the table than the temperature higher than 20 DEG C, but must pay attention to the following circumstances. When the barrel temperature is lowered, the detention time is too long, which will not cause the aging of granular material in the container and no corrosive gas. Therefore, there will be no big problems if the residence time is long. However, if the molding is interrupted for a long time, please reduce the temperature of the barrel. When it is re formed, it is good to throw out a few models.

The runner and gate: because PA612r solidification time is very short, the gate location is important. The aperture not less than 0.5*t (where t is the thickness of plastic parts). If the use of hot runner, gate size should be smaller than the use of conventional channels, because of the hot runner can help to prevent premature freeze. If you dive into the gate, the minimum diameter of the gate should be 0.75mm Defect treatment Resolvent： 1. Check whether the raw materials are wet or mixed with other materials 2. Check whether the raw material is decomposed in the barrel (barrel temperature) Too high, the screw speed is too fast) 3. Check whether the nozzle hole is too small 4. Check whether the model temperature is too low 5. Bad die exhaust 6. Whether the size of the gate is too small 7. The back pressure is too low and the recycled material is too much The solution of weld mark in the processing of nylon 612 products: The mechanism is that the low bonding temperature is very low at the end of the flow at the end of the flow, so that the combination of the two strand flows is not close. Resolvent： 1. Increase the pressure and speed of injection 2. Improve the mold temperature 3, improve the temperature of the material 4. Improve the mold The solution of the exhaust and shrinkage of the nylon 612 products during processing: The mechanism is the injection or shrinkage of the product. If it was solved by injection molding If it is to shrink the water, the solution is solved. The solution of the focal spot produced during the processing of nylon 612 products: The mechanism is that when the injection speed is high, the rubber cavity will occupy the mold cavity at high speed. When the gas in the mold cavity is not enough to exclude, the gas will be compressed and the product will be scorched after the gas is compressed.
