Precision preformer is a kind of high-efficiency and high-precision device for manufacturing rubber blank. It can be used in combination with a wide range of rubber material in extruding rubber blank of mid to high hardness and of intricate shapes such as circle and solid figures. Owing to its high precision volume and low air content, it is capable of producing products ranging from rubber sundries, sealing members, inflating valves, tennis balls and shoe soles.
Structure introduction
The precision preformer is composed of a ram extruder and a rubber blank cutter attached to the ram head. It is also equipped with hydraulic, vacuum, heating, pneumatic and electrical system. While in operation, the first step is to open the ram head and add the preheated prehensile rubber material into the machine from anterior part of the barrel. After that, the ram head is to be closed to adjust the extruding and cutting speed (volume control chart is provided with the machine). Eventually, after vacuumization and cutting, the rubber blank with precise weight will then be obtained.
