How They’re Manufactured
Manufacturing a silicone diaphragm starts with selecting raw materials. Also, because they are composed of silicone, only the best raw materials are used in their production. Then, cut into a precise shape and size afterward. Its edges must still be trimmed cuts before being placed in the mold. This process softens the silicone as heat is applied.
After a particular duration, the molds are removed, ensuring their perfect expected result. After being reviewed, taken product is set for the final shaping- a process for carving.
