Vacuum Vulcanizing Press for Rubber Oil seal /Vacuum Molding Machine for Rubber Oil seal/Vacuum Curing Machine for Oil seal :
DH-SV Vacuum rubber oil seal machine is designed for oil seal production specially.
1.Specializing in manufacturing all kinds of industrial and automotive oil seals,mechanical seals and other rubber products;
2.Using high negative pressure vacuum hood design,so that a mold can be in a nearly full vacuum environment,improving mold venting;
1. Vacuum hood device make Vulcanization time shortened,improving production efficiency.
2. High vacuum systems, material flow resistance, to eliminate air bubbles within the product package, product zero defects.
3. Quick opening and closing mold, high production efficiency; slow locking to protect the mold; automatic mold, exhaust, from the type of automatic cycle, each stage can be freely controlled.
4. PLC programmable controller and touch screen LCD, simple operation, the user can quickly modify their process requirements and lock process parameters, to ensure product quality.
5. Electric heating using stepwise heating pipe, high precision temperature control, temperature display and intuitive.
6. With automatic pressure compensation function in the suppression of the process can be automatically added material flow caused by the pressure drop.
7. Institutional design is simple, maintenance more convenient.
