FULL SYSTEM
A stable and economic production process largely depends on the
quality of the process components. Equally important and often
underestimated is the importance of coordination of the individual
components to one another.
As a full system supplier, BETTER develops and manufactures all
relevant elements for a LIM production cell in China in compliance
with the strictest quality guidelines. Through years of experience
BETTER is specialized in integrating its own product range with the
appropriate injection molding machine and other automation
components into a complete cell.
The customer specifies the part geometry and tolerances, the annual
production volume and any further requirements. In a fixed-price
offer BETTER presents the turnkey solution including all required
components, as well as an extensive acceptance procedure and all
necessary training.
This makes BETTER to your specialist and leading partner for high
grade Turnkey Solutions for LSR (liquid silicone rubber) injection
molding worldwide!
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.
