    Instructions


    Here is a look at the LSR molding process:

    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.


    Packing & Storage


    Available in 20kg pails or 200kg drums.

    Store in a cool, dry place out of direct sunlight, use it within 12 months from the day of manufacture.
