Abstract

PURPOSE: To improve the yield of a material and to reduce the cost for a product, by forming a mold for injection molding of a silicone resin such that the areas of the cross sections of the sprue part and the runner part thereof are respectively 1mm2 or less.
CONSTITUTION: A silicone resin is injection molded using the injection mold wherein the sprue part 5 and the runner part 6 thereof have respectively a cross sectional area of 1mm2 or less. Preferably, the cross sectional area of the gate part 7 is smaller than that of the runner part. The gradient of the sprue part may be zero. Although the silicone resin in the injection path would be thermosetted or cured and cannot be recovered, as the cross sectional area of the sprue part and the runner part is made small, the loss of the material is minimized, and the yield of the material is good. The configuration of the gate may be in the form of an edge gate or a submarine gate.
