The development of the H (5500) PSI series of high-pressure precision pre forming machines is to meet the growing demand of the rubber industry for processing high hardness rubber or special rubber, which cannot be processed by the ES standard series precision pre forming machines. 2、 The production capacity comparison between high-pressure preform and standard preform is that the high-pressure preform machine with 5500PSI has a production capacity six times higher than the standard machine with 3000PSI. This type of machinery is particularly necessary when rubber requires filtering and pre molding to reduce pollution or remove impurities inside. Although ES series machines are capable of filtering impurities, single standard preforms can sometimes greatly reduce production. The high-pressure H series machine can achieve a rubber extrusion pressure of 5500PSI, undoubtedly meeting the production needs of manufacturers. 3、 Larger production capacity
