讓許多養(yǎng)牛戶不愿意養(yǎng)再比如:枝葉繁茂株型松散的品種TPEE UV655M防腐 耐磨耐 高低溫 LCP Taking into account the service life of the screw, the temperature difference between the rear part, the middle part and the front part 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.
Reduce the barrel temperature when the retention time is too long, will not cause the pellets in the barrel aging, does not produce corrosive gas, so long residence time is generally not what big problem. However, if the length of time to break down, please reduce the barrel temperature, once again, to throw away a few good.
The barrel temperature of each grade at molding (c)

Resin temperature 290-320 320-350 340-360 290-320
2 mold temperature
LCP plastic raw material can be molded in a mold temperature of 30 degrees Celsius -150. But we generally set the mold temperature at 70 C -110 C. In order to shorten the molding cycle, preventing burr and deformation, should choose the low mold temperature; if the stable product size requirements (especially for products under high temperature conditions), reduce weld seam generating and solving the problem of insufficient filling, should choose the high mold temperature.
3 can be plastic
The rotating speed of the screw is generally 100rpm. If it is containing glass fiber or carbon fiber materials (such as: A130, A230, etc.), in order to prevent the glass fiber was broken, we must choose a relatively low speed. In addition, the back pressure is also as low as possible. When the barrel temperature is set to 300, the retention time of the material in the barrel has an effect on the mechanical properties and color of the plastic.
4 injection pressure and injection speed
The most appropriate injection pressure must depend on the shape of the material, the shape of the product, the design of the mold (especially for the straight runner, runner, gate) and other molding conditions. But no LCP grade the melt viscosity is very low, so the injection pressure than general thermoplastic resin to low. It is a good way to start with low pressure, and then slowly increase the pressure. Probably the products in 15MP
