Product details

The Coors company specializing in the production of precision pre-molding machine, mature production process, and rubber industries in the Yangtze River Delta economic famous users return visit to evaluate excellent. I attach great importance to customer satisfaction and strive to improve the customer needs.After-sales maintenance due diligence to do then, and I plant with extremely high precision the various humanized operation design, in order to achieve a low-maintenance, simple operation.

A device Description:
The precision pre-molding machine is a high-efficiency, high-precision plastic embryo production equipment. For various rubber adaptable, able to produce a variety of shapes, such as: ring, rectangular, cylindrical, ... and so on. Suitable for Rubber various fields gum embryo production, such as: seals, oil seals, valve, plug, damping class product. Production of finished plastic embryo weight of the device is very uniform, no bubbles, no lap. And glue embryo weight accurate to ± 0.1 g, glue embryos were vulcanized, basic outlet, or outlet thin as onion skin, and can easily handle.
1, the structure Introduction
Pre-molding machine is cutting device and composed by a plunger extrusion device and a package of gum in the machine head embryo, mainly with the following key part:
Hydraulic system: selection of high-pressure gear pump, imported from Japan YUKEN (Yuken) flow valve, the equipment before and after use rubber extrusion speed remains constant, ie extrusion speed stability, balanced product weight, can be accurate to ± 0.1 g.
Extrusion barrel: sturdy chrome alloy extrusion barrel, in the decades of the high temperature, friction, extrusion pressure and pumping vacuum suction original shape and size remains unchanged. To ensure that the extrusion process, there is no gap between the piston and the tank wall is extrusion velocity stability another security.
Vacuum system: fully sealed vacuum system, the extrusion barrel, die and be extruded rubber compound there is no point air, to ensure the precise the glue the embryos volume quality extruded.
Heating systems: water circulation heating mode, the digital display temperature controller, to ensure a constant temperature of the head and barrel.
Cutting device: preformed nose with a rubber traffic speed surface machining system, the maximum speed of the single-pole up to 300 rev / min.
Electrical control: LCD flat-screen computer control and manual control two devices to choose from.
Pneumatic device: used to control the opening and closing of the nose.
In addition, also equipped with differential pressure display, display equipment failure. Simultaneous extrusion apparatus can also be used as a plunger-type extruder, for filtered gum and produced apex.
2, the work program:
Precision pre-molding machine, turn on the power, compressed air valve, the water cycle switch, and allow the device to preheat to the set temperature, open head, will be loaded from the front part of the barrel after preheating the rubber hit the volumeand then turn off the nose, vacuum, set extrusion speed and cutting speed start extrusion, cutting, measurement and adjustment, you can get what you want accurate weight plastic embryo.

Advantages:
l plastic embryo precision up to ± 1%, and save a lot of raw materials
l high production efficiency, output speed
l high rate of return on investment, long-term benefit
the l simple structure and easy to operate
l equipment durability and less maintenance
