Liquid silicone can be used to injection mold
pure silicone products with various shapes and physical properties through
molds alone. It can also be bonded with accessories made of other materials
into silicone overmolding parts through the liquid silicone overmolding
process. Liquid silicone can overmold common materials such as PC, TPU,
hardware, and stainless steel. Liquid silicone rubber (LSR) is fully named
injection molding liquid silicone rubber, and its vulcanization equipment is an
injection molding machine. The injection molding machine has many advantages,
such as a very simple process flow (it doesn't require manual processes like
ingredient mixing, rubber mixing, cutting, and material arranging in the
high-temperature rubber process, and only one worker is needed to take out the
products), high product precision (all manual procedures before molding are
replaced by machines), high production output (the A/B glue can be molded in
just a few seconds at a certain temperature), labor-saving, power-saving, and
material-saving. It can produce all the products that can be made with
high-temperature rubber. What are the characteristics of liquid silicone
products?
Good stability at high and low
temperatures.
Inert (odorless and tasteless),
hardly reacting with other substances.
Transparent and easy to color,
capable of producing products in various colors.
A wide range of hardness, from
10 to 80 Shore hardness.
Good resistance to chemicals
and excellent acid and alkali resistance.
Good elasticity, and the
produced seals have excellent sealing performance.
Non-conductive, with good
electrical insulation performance.
Good resistance to compression
set, and it can restore elasticity even after being compressed for a long time.
In addition to the above outstanding properties, compared with conventional organic elastomers, liquid silicone is also particularly easy to process and manufacture. Liquid silicone has good fluidity, so it can be molded, calendered, extruded at low energy consumption, or directly cured at room temperature or with heating. Easy processing also means an improvement in production efficiency.
