In addition, LSR compounds do not shrink in the mold like thermoplastic compounds; they tend that will thermally expand and shrink a little when cooled. In order avoiding air stagnation, it is important to set a good exhaust device while in the mold.

The structure of thermoset fruit juice silicone rubber (LSR) injection molds is usually similar to that used with regard to thermoplastic compounds, but there can be significant differences. as far as it can be in the open without affecting the item appearance and function, can be at the edge or at the end; in the vicinity of the gate in the cold material, as often that they can to set the pull fishing rod, in order to facilitate that sprue release; large or washboard products,

it is recommended to utilize a multi-point pouring, to prevent product warping and deformation and not enough material; Its location should be chosen making sure that the plastic filling process is the shortest place, in order get rid of the pressure loss, is conducive to mold exhaust; in the vicinity with the slender core to avoid opening the gate to avoid direct impact on the core on the stool mould material flow, resulting in deformation and also misalignment;

the size of the gate is decided by the product size, geometry, structure and method of plastic, can take a small size and then modify according to the check mode; through the mold movement analysis or experience, determine the product with the location of the gate and the resulting line, whether the item appearance and function, can be create to solve the cold content points; 9.
