molding machine is built for customers producing UF toilet seat covers, thicker seat covers or premium sanitary ware resin parts who want more output from the same factory space. It keeps the advantages of the single-layer HCB press, including heated platens, hydraulic holding pressure, core pulling, daylight and demolding control, then combines two mold levels in one machine.<\/p>\n<p>This machine can press two mold sets at the same time. The upper and lower layers are designed for synchronized venting and pressing, so both levels can maintain consistent density, appearance and curing conditions. With the same operator and less floor space than two separate machines, the customer can increase output while reducing power and labor cost per part.<\/p>\n<h2>Key machine advantages<\/h2>\n<ul>\n<li>One machine runs upper and lower mold sets together for higher double-layer toilet seat output.<\/li>\n<li>Synchronized venting and hydraulic holding pressure help keep both UF product layers consistent.<\/li>\n<li>Retains the single-layer HCB strengths: heated platens, core pulling, daylight, demolding and PLC operation.<\/li>\n<li>Cast-iron upper seat, middle seat and lower cylinder base support machine rigidity; imported components, CE documents and optional IoT monitoring can be discussed by project configuration.<\/li>\n<\/ul>\n<p><script>(function(){var
