This silicone diaphragm is produced by compression molding. Compression molding can satisfy the multi-color production that customers demand. Our expertise in silicone manufacturing and years of experience can give us the best solution to silicone product needs.

Why Choose Silicone Instead of Plastic?

Environmental awareness around the world is rising, people pay attention and use environmentally friendly material. Not only on daily necessities, but also on medical treatments, replacement parts must change to environmentally friendly materials. Such as stethoscopes, people originally used plastic auscultation diaphragms, but in view of the environmental damage caused by plastics, people began to replace plastic with silicone as diaphragm of the stethoscope.

In addition to meeting environmental protection requirements, silicone diaphragms have better air tightness and better sound transmission. The diaphragm of the stethoscope is medical-grade silicone, which has biocompatible, soft in texture and reduce allergy.
