A primary molding machine that uses plastic particles directly has recently been successfully developed and marketed by Shanghai Jiading Yundu Machinery Company.
Compared with the secondary molding machine, the primary molding machine does not require a sheet machine, thus reducing the production cost by 50%. The plastic ions enter directly from the hopper of the extruder, and the product comes out of the end of the molding machine. The raw material usage rate reaches 100%. Due to one-time molding, the speed is high and the yield is high.
The unit is particularly suitable for the use of degradable plastic raw materials. The molding part adopts synchronous pressure pull and synchronous suction design, which makes the finished product high in color and uniform in color.
