Product Description

Liquid Vertical Injection Molding Machine With Double Sliding Board.

BETTER LSR Injection Molding Machine made with CE and ISO Production Controller, Vertical Double Slides Table LSR Injection Molding Machine is widely used in medical silicone products, electron silicone seal,ect.

Vertical Liquid Silicone Rubber (LSR) Injection Molding Machine,Direct pressure mould opening and closing system, horizontal injection structure, it can adjust the mould faster, and control the position more precisely. It is more suitable for producing the LSR parts which can be automatically removed from the mould.

The main feature of the vertical LSR molding machine:

* Advanced sliding rail structure, which can reduce the oil pollution and make the machine works faster and steadier.

* Active pin valve-pattern nozzle sealing system, which can guarantee the injection more accurately.

* Meet the requirements on multi-station production

* High-performance servo motor system is installed, which can guarantee the machine work more accurately and more energy-savingly.

Characteristics

1) Compared with the solid rubber molding, the liquid silica gel injection molding does not need the operation procedures such as molding, mixing, pre molding, etc., which saves manpower, material resources and energy, reduces equipment investment and floor space.

2) The injection molding of liquid silica gel can realize the automatic processing under the fully closed condition, eliminate the manual operation deviation, reduce the influence and pollution of various variable factors in the processing, and ensure the dimensional accuracy and internal quality of the product, which is conducive to the application of liquid silica gel in medical treatment.

3) Because the viscosity of liquid silica gel is very low (generally in the range of 10-1000pas), and its fluidity and processability are good, its injection pressure is much lower than that of solid rubber and plastic. Generally, the injection pressure is 20MPa, which can be lower than 1MPa in some cases. Therefore, it can produce products without flash, reduce material waste, and reduce the wear of equipment and mold. In addition, due to the good fluidity of liquid silica gel, it is especially suitable for forming large-scale products, extremely complex shape products or ultra-thin products, such as ultra-thin products with a forming thickness of 0.5mm and a length of 100mm, which is difficult for solid rubber materials to form.

4) The curing rate of liquid silica gel is very fast. During injection molding, the curing reaction can be completed in the range of 160-220 seconds to several minutes, so the molding cycle is short and the production efficiency is high.

5) The back pressure required for liquid silica gel in screw metering is very small, generally less than 1.5MPa. For some liquid silica gel materials with very low viscosity, even no back pressure can be set, which is mainly due to the good fluidity of low viscosity silica gel and the low gas content in liquid silica gel in normal operation. On the contrary, the large back pressure will increase the density of the unvulcanized silica gel and destroy the accurate measurement effect of the metering device.

6) Liquid silica gel does not shrink in the process of injection molding, but due to its high thermal expansion coefficient, it usually shrinks by 2% ~ 3% after demoulding and cooling. The exact shrinkage data depends on the material formula. From the point of view of processing, designers should consider some factors affecting shrinkage in advance.
