Preformer can produce preforms with high efficiency and high accuracy. Its biggest advantage is to extrude accurately all kind of medium/high-hardness preforms with different shapes, like ring, bar, three-dimension and so on. It features cost-saving, and also space and power savings, since the ES Range consumes a fraction of the power and occupies only a small amount of floor space when compared with alternative methods. The main advantages are as below: 1.The accuracy of all ES Preformers and Extruders is up to +/- 1% by volume and this means that substantial compound savings can be achieved in preform production 2.Higher output and productivity 3.quality Guaranteed 4.Easy installation and operation 5.A quick return on investment: It can be ensured through savings on material and labour alone Expandable fields 1.It is used widely in Rubber industry, O Ring, Valves, Oil seal, Golf, Tennis, Automotive, Footwear and other industries.
