Precision Preformeris a type of rubber blank manufacturing equipment with high efficiency and high accuracy.
It can process a wide range of all rubber material including silicone, Natural rubber, NBR and FKM compound etc. It is able to extrude rubber blanks of circular, rectangle, strip and odd shapes. It is especially suitable to produce sealing, oil seal, tire valves, bottle stoppers, tennis balls, shoe soles and friction lining, etc. It integrates a variety of different functions such as vacuuming, filtrating, extruding, cutting, weighing, counting, etc.
Structure Introduction
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 machine head and load the preheated rolled rubber material into the machine from front part of the barrel. Then set the extruding and cutting speed. After taking vacuum, extruding and cutting, the rubber blank with precise weight will be obtained eventually.
1.Extruding device: It is composed of hydraulic cylinder, batching barrel and machine head.
2.Hydraulic device: Hydraulic oil volume in hydraulic cylinder is controlled by the flow valve and the pressure difference prior to and after throttling is controlled at a constant value so as to ensure the precise weight of the rubber blank to be cut.
3.Pneumatic device: It is used to open and close the machine head moved by pneumatic cylinder.
4.Vacuuming system: Before extruding and cutting of rubber material, the vacuumization aims at eliminating the air entrapped inside the barrel and the machine head in the rubber material so as to improve the quality of cured products in the next following process.
5.Heating system: With the adoption of water circulation heating method, the temperature is controlled and displayed by the digital thermostat which can effectively maintain the constant temperature of machine head and barrel.
6.Cutting device: It is composed of frame, a motor and a speed reducer .And under the bottom of the frame is a conveying device.

Fit a set of electronic scale loop feedback system unit in the updated JY Precision Preformer, do not need to change former electrical and mechanical structure, and then achieve in controlling the blank weight automatically.
The operator enters the “Target Blank Weight” on touchscreen, and connect the reference data, to control the blank weight adjusting the cutter speed through the scale weigh loop system. It is with the data saving function which is convenient for production management, which enable to reduce material waste caused by repeated manual adjustments (cutter speed & valve setting), Improve the rubber blank weight accuracy meanwhile improve production efficiency.
