Operation ways of Injection Molding
1, mixed: A component (based glue) and Part B (curing agent) ratio of 10:1 or 1:1 by weight, mixed, mixed either manually or using equipment.
2, vacuuming: mixed silicone A and B, When used in small amounts can be in a vacuum desiccator under vacuum, the volume will foamed plastic material can be increased 4-5 times, so degassing vessel volume should be less than bulky plastic material 4 to 5 times, after a few minutes gel volume returns to normal, no air bubbles escaping when the surface (about 10 minutes) to complete the degassing step.
3, clean your Original mold (sex toys molds), please note that the molds won’t contact with condensation silicone rubber before, and not contains a chemical element such as N.S.P, otherwise, the silicone won’t be cured.
5. cured the silicone rubber at 90℃ to 150℃, then the silicone will be cured, and then demould.

Instructions
1. LSR A + B components typically come in a 5-gallon pail or 55-gallon drum. A process controlled pumping kit presses down on the buckets to force the material into the static mixer and feed into the injection unit.
2. Then, streams of pigment can be added and controlled. In the injection, press material will be mixed together additionally with a screw and pushed forward to create a “shot” of material, or the amount needed to fill the mold.
3. After the material is injected into the mold, it will then stay clamped together to cure the LSR. Then, either an operator or a robot will remove the cured product from the mold and the cycle repeats. It is a very quick efficient process that typically averages 30 seconds.
Notice
This product cannot be contacted with compounds containing N, P, S to avoid affecting the catalytic effect of platinum.
