Septums are essential components in many medical devices, providing a means for repeated, sterile access to internal cavities.  Their self-sealing properties, material flexibility, and ability to maintain sterility make them invaluable in various applications, from drug delivery and sample collection to diagnostic devices and laboratory equipment.  Heat staking is a commonly used and highly effective method for attaching septums in medical devices.  It provides a strong, durable bond that can withstand repeated use and mechanical stress, while also maintaining sterility.  The precision, consistency, and cost-effectiveness of heat staking make it an ideal choice for the high-volume manufacturing of medical devices that utilize septums.
