◆ forming conditions
(1) The processing temperature of South Asia PBT resin is 250 ~265 ° C. if the resin temperature is more than 275 ° C, theretention for a short time will lead to physical propertiesreduction or decomposition.
(2) The mold temperature, about 40 ~ 80 ° C, is suitable. If youwant to get a beautiful surface or a good dimensional stability,you should also pay attention to the mold temperature. In a word,PBT products with enhanced specifications or precision forming needhigher die temperature.
(3) When forming is completed, the remaining resin in thematerial pipe must be discharged and the material pipe must becleaned with PE, PP or PS.
◆ mold
(1) Surface processing of die: for the die required by thestrengthening specification, the die surface shall beelectroplated, planed and to ensure the durability of thedie.
(2) Gate: gate types such as Side-gate and Pin-Gate can beused,
(3) Vent hole: in order to solve the burning phenomenon offormed products due to poor exhaust, the vent hole with thicknessof 0.02mm and width of 1-5mm can be used for reference.
◆ thermal stability during melting
The effect of retention time on the physical properties of PBTat high temperature in South Asia. The user can know that at 270 °C under high temperature, the retention time is more than 0.5hours, and the physical properties are reduced by more than 20%.South Asia PBT 1403g6 is widely used. If it is expected to be usedfor a long time (more than 0.5 hours) to stop the operation, it isnecessary to reduce the material pipe temperature to ensure theproduct
