What is a Liquid Silicone Rubber LSR Menstrual Cup?

Liquid Silicone Rubber LSR Menstrual Cup, also knows as LSR Period Cup, Liquid Silicone Menstrual Cup, Female Period Cup, which is a feminine hygiene device that is inserted into the vagina during menstruation. The Menstrual Cup purpose is to collect menstrual fluid (blood from uterine lining) and prevent its leaking onto clothes. The LSR Menstrual cups are usually made of flexible medical grade liquid silicone and produced by LSR Liquid Silicone Rubber Injection Molding and shaped like a bell with a stem. The stem is used for insertion and removal. The bell-shaped cup seals against the vaginal wall just below the cervix. Every 4–12 hours (depending on the amount of flow), the cup is removed, emptied, rinsed, and reinserted. After each period, the cup should be boiled for at least 5 minutes and stored for use the next month.

Liquid Silicone Rubber LSR Menstrual Cup Manufacturing Ways

Nowadays the Liquid Silicone Rubber LSR Menstrual Cup are mainly manufactured with FDA Medical Grade Liquid Silicone rubber, and produced by Liquid Silicone Injection Molding.

At earlier times, Menstrual Cups were mostly made by compression mold, while with the time going, people have higher requirements about quality and appearance, because for the menstrual cup made by compression molding, it is not so high transparency, and flashing & parting is big, which probably will effect the using experience.

Therefore, the designer & manufacturer choose to produce the period cup by liquid silicone injection molding

In this way, firstly, there will be minimum parting line, which is almost invisible, and also flashing will be quite small.

Secondly, mold life will be longer than compression mold, about 500Kpcs shots.

Thirdly, liquid silicone is Platinum Cured Silicone, which is safer than solid silicone. 

Fourthly, all these can provide a better user experience
