LSR Silicone Keypad
LSR Silicone Keypad, as called as Liquid Silicone Rubber Keypad, Liquid Silicone Keyboard, Liquid Silicone Buttons, which is made of high transparent, high tear strength, good resilience, good water, heat, cold resistant liquid silicone rubber by high precision Liquid Silicone Rubber Injection Molding.
LSR Silicone Keypads are widely used in different applications, such as: medical, industrial, instrumentation and communications equipment.
Most Silicone Keypads are molded by compression molding, because compresion molding is much cheaper and by using good metal steel, can also have very good quality silicone keypads. While because of liquid silicone rubber's excellent property, more and more customer would like to choose Liquid silicone as material.
LSR Silicone keypad 's advantages compared to solid silicone keypad:
LSR Keypad has wider Shore Hardness, can achieve 5-90A. For compression molded silicone keypad, the lowest hardness is 30A. And normally, we suggest to have 50-60A silicone keypad by silicone compression mold. So wider Shore hardness range is also an important reason to choose Lqiud Silicone Rubber as material.
Liquid silicone rubber keypad is higher precision, with small parting line,no or less silicone rubber flashing, and have stable buttons's design and size tolerance, the tolerance can be +/-0.02mm.
LSR Keypad has longer keylife time. LSR has better property than solid silicone: higher tear strength, good resilience, water resistance, heat and cold resistance, and is high transparency.
LSR Keypad has higher production efficiency. Do not need work to place material anymore, and shot cycle time is shorter.
