Eastman copolymer polyester processing guide

1. Injection molding machine

1) common to higher screw injection molding machine, it is suggested that the compression ratio of 2.5:1 ~ 3.0:1, the ratio of length to diameter L/D = those days.

2) the finished weight shall be the largest injection molding machine injection amount of 30% ~ 75%.

2. Processing:

1) drying: desiccant type (desiccant dryer) or hot air circulation drying machine (Hopper dryer), 65-70 ℃, 4 to 6 / h.

2) material temperature control (see table gun barrel set temperature, pay attention to control the actual temperature and set temperature) :

Low low processing temperature and short residence time (< 5 minutes), the physical properties of materials can be obtained better;

Suggest to measure the actual temperature of the rubber, according to the different type normal temperature range of 230 ℃ ~ 270 ℃.

 

Brand front after the middle period of the mouth

GN120, 240-250, 230-240, 220-230, 220-220

(temperature should be regulated according to the actual situation of the machine, the temperature of the MTK mostly on the high side, will be subject to actual can stable injection)

Low mold temperature: it is recommended to use cold water cooling mold, mold temperature range: 15 ~ 40 ℃.

Low RPM, low RPM can prevent the rubber temperature is too high, suggested use: 60-90 RPM;

Low buffer layer (as the size) : it is recommended to use 5-10 mm range of buffer layer, on the one hand, can prevent the material degradation due to stay a long time, on the other hand can reduce injection pressure loss;

Low residence time: rubber gun barrel in the stay time should be controlled within 5 minutes, otherwise should make clear plastic to plastic beer;

Low back pressure: appropriate back pressure can strengthen the plasticization of rubber and the help of the exhaust function, suggested use: 5-10 KGF/cm2;

Low cleaning machine: before using Z - polyester, must use transparent PC material cleaning machine; After using Z - polyester, available and strength, PS material such as the machine.

Cooling time: this material the slower cooling rate, the viscosity, should according to the thickness of the mould structure, product set appropriate temperature and cooling time, the main gate of patterns to design in 3-5 ° Angle or the runner is easy to mold.

Material advantages: good toughness, strong liquidity, highly transparent, easy to shape.

* drying: not all of the plastic needs to be dry before processing, PE, PP, and other products without drying. But the polyester is a product of acid and glycol by reaction, water is a by-product of the reaction. Under the melting temperature, the reaction is reversible, therefore before processing or the reverse reaction occurs, must be removed will absorb the moisture.

1 + 1 or more acid copolymer polyester or more glycol + water

Remember: 1, drying materials 65-65 degrees, baked foot for four hours. 2 must be used before, processing shuikou PC or clean PC machine. 3, mould temperature should be controlled within 40 degrees.
