Thanks to the advantages of LSR (liquid silicone rubber) such as high transparency, odorless and tasteless, moderate viscosity, high insulation, high and low temperature resistance, wear resistance, weather resistance, biocompatibility, etc, its products can still maintain stable functional performance in extreme environments, so it is widely used in many fields such as architecture, electronics, automobiles, medical treatment, machinery, etc. At the same time, LSR injection molding technology has further promoted product innovation in related industries after significant innovation. Relevant foreign institutions predict that the scale of LSR products market will continue to grow at a compound annual growth rate of 9.25 percent, and it is estimated that it will exceed 4.3 billion dollars by 2028, while the Asia-Pacific region is the largest application market of LSR.

However, unlike the hot liquid filling cold mold used in the thermoplastic injection molding process, LSR injection molding uses cold liquid filling heated die, so when direct pouring, thermoplastic plastic uses "hot runner", while LSR uses "cold runner", the temperature control of the mold is more important. In addition, LSR can easily flow in the gap narrow to 1cm by virtue of its low viscosity, so the mold processing precision is required to be high and the molding pressure requirement is significantly reduced.

Thus, mold design and process are particularly critical for LSR injection molding. In the actual production process, there are many discussions around the difficulties of LSR mold design: how to improve the effect of mold temperature control system? How to improve the heat insulation effect between cold runner and hot mold? Where is the most suitable gate location? How do I determine the location of air trapping? What should I do if the filling of multi-cavity products is uneven? How to estimate the curing time and curing degree? How to optimize the production cycle......

The problem is solved skillfully, of course it depends on SIGMASOFT.^®Virtual forming technology! Mold flow can be easily brought into the whole set of mold and gating system, set the same technological conditions as the machine, run multiple production cycles virtually, and accurately simulate the whole process of the product from preheating to molding, therefore, the product development process can be greatly accelerated, and virtual mass production can even be started before mold manufacturing.
