Abstract:Before EPS (expandable polystyrene) products are molded,it is necessary to use a pre-expander to process the EPS raw materials to the required density .The stability and accuracy of density play a decisive role in the quality of the entire EPS product.The EPS pre-expander weighing feedback correction system developed by Zhejiang Alaixi’ao Intelligent Equipment Technology Co.,Ltd. reduces manual intervention in the pre-expansion process through the application of automatic weighing feedback and correction technology. The pre-expansion parameters are adjusted through calculations via the PLC control system based on the feedback value to enable the pre-expansion density result is always maintained at the specified value. After continuous testing and statistics after the application of this technology,the raw material accumulation density error is kept within ±1.5% of the set value.
