Manufacturers looking to Enter this market should aim to understand and adapt to its evolving dynamics, focusing on consumer needs and preferences. So how should we develop a distinctive menstrual cup product? Next, I will give my thoughts.

Product advantages of silicone menstrual cup

If we want to develop a silicone menstrual cup, we must first know why it is popular. In other words, we must understand the advantages of this product.

Compared to other menstrual personal care products

Silicone menstrual cups offer several advantages over traditional menstrual products like sanitary pads and tampons.

Unlike pads and tampons, which are typically used once and then discarded, silicone menstrual cups are reusable and can last for several years with proper care. This not only makes them more environmentally friendly, reducing waste, but also more cost-effective in the long run.

Another advantage of silicone menstrual cups is the health aspect. They are generally considered safer than tampons, which can cause dryness and leave fibers behind. Menstrual cups also carry a lower risk of Toxic Shock Syndrome (TSS), a rare but serious condition associated with tampon use. Furthermore, silicone is hypoallergenic and does not contain the chemicals and fragrances found in many pads and tampons, making it a safer choice for sensitive skin.

Compared with menstrual cups made of other materials

When compared to menstrual cups made from other materials, silicone cups stand out for their durability and flexibility. Silicone maintains its shape and flexibility over a wide range of temperatures, making it ideal for the varying conditions it will encounter. Its durability ensures that the cup can be folded and manipulated for insertion without losing its integrity. High-quality medical-grade silicone is less likely to cause irritation or allergic reactions, unlike rubber or latex cups.

Silicone’s non-porous surface also makes it easier to clean and less likely to harbor bacteria, an essential factor for a product used in such a sensitive area. Its smooth texture makes insertion and removal more comfortable compared to cups made of stiffer materials.

Analyzing Customer Needs

The first step in designing an effective silicone menstrual cup is a thorough analysis of customer needs. Common investigation methods include surveys, focus groups, and market research. understanding the age range, lifestyle, and preferences of potential users helps tailor the product.

Design Responses to Customer Needs

The size and shape of menstrual cups are not one-size-fits-all. Different users have different anatomies and flow levels, necessitating a range of sizes and shapes. Some may prefer a smaller cup for ease of insertion, while others might need a larger capacity for heavier flow days. The design must accommodate these variations without compromising on comfort or effectiveness.

The Survey found younger users may prioritize discretion and ease of use, while older users might focus on comfort and capacity. Based on it, product design can be specifically tailored. For younger users who favor discretion and ease of use, the design can include features like a more flexible material for easier insertion and a compact shape for portability. For older users, who might prioritize comfort, the design can focus on ergonomic shapes that conform to the body comfortably and offer varying sizes to accommodate different flow levels.

Broadening the Appeal with Variety

You can also focus your survey on users’ pursuit of personalization. While some users might prefer the classic, medical look of clear silicone, others may find colored cups more appealing or less clinical. Offering a range of colors allows users to choose according to their personal style, making the product more appealing to a broader audience.

Innovative Features for Enhanced Usability

Ease of cleaning and maintenance is a universal concern among potential users. In response, the design can incorporate a smooth, seamless surface, reducing the effort required for cleaning.in addition, features like a textured base or a ring stem can be introduced, catering to user preferences for easier removal without compromising hygiene.

Linking customer needs directly to product design ensures that the silicone menstrual cups not only meet the basic requirements but also address specific preferences and concerns.

Medical-Grade Liquid Silicone Rubber (LSR)

The recommended material is medical-grade liquid silicone rubber (LSR), specifically designed for its compatibility with the human body and its ability to meet medical standards.  It is a high-purity, platinum-cured silicone that is non-toxic and hypoallergenic. Its curing process doesn’t produce any by-products, making it safer for intimate contact. LSR maintains its properties over time, even with regular sterilization and use.

Specific Shore Hardness

For menstrual cups, a Shore A Hardness in the range of 40 to 60 is ideal. This range provides the right balance of flexibility and firmness. A hardness level around 50 Shore A is commonly used, as it ensures the cup is soft enough for comfort but firm enough to provide a leak-proof seal.

Compliance with Standards and Regulations

The silicone material should comply with relevant international standards and regulations, such as the U.S. Food and Drug Administration (FDA) regulations for medical devices, and the European Union’s REACH and RoHS directives. These standards ensure that the silicone is safe for prolonged contact with the body and is free from hazardous substances.

Sourcing the silicone material

To maintain high standards of quality and reliability, manufacturers are advised to procure silicone from reputable and well-established suppliers (like Wacker). Established suppliers have stringent quality control processes, ensuring the material meets all necessary standards. These suppliers not only guarantee the quality of the silicone but also provide traceability.

Manufacturing of silicone menstrual cups

The manufacturing process of silicone menstrual cups is meticulous, beginning with the selection of a reliable silicone manufacturer. The chosen manufacturer must adhere to strict quality and safety standards, notably ISO 13485. This standard is specific to medical devices, ensuring a consistent design, production, and delivery of products that meet both customer and regulatory requirements.

The creation of precise tooling is a critical component in producing high-quality silicone menstrual cups. Tooling refers to the design and fabrication of the molds used in the injection molding process. At this stage, the quality of the mold directly impacts the quality of the final product.

Tooling

The tooling process begins with a detailed design phase, where engineers create a mold design that accurately represents the desired dimensions and features of the menstrual cup. This design must account for factors like the cup’s size, shape, flexibility, and any additional features like grips or ribs. Advanced computer-aided design (CAD) software is often used to create a precise and detailed representation of the mold.

Once the design is finalized, the mold is fabricated using high-precision machining tools. Materials used for mold-making are typically durable metals like steel or aluminum, chosen for their ability to withstand the high pressures and temperatures of the injection molding process. Even minor deviations can lead to product defects or inconsistencies.

Liquid silicone injection molding

The process moves to the actual production phase. The mainstream manufacturing method of silicone menstrual cups is injection molding.. This method is favored for its precision and ability to produce consistent, high-quality products. Injection molding involves heating the medical-grade liquid silicone rubber (LSR) to a liquid state and then injecting it into a precisely designed mold. This mold defines the shape and size of the menstrual cup, including intricate details like grip rings or stems.

The precision of injection molding allows for the production of menstrual cups that meet exact specifications for size, thickness, and texture. The process is highly controlled, ensuring that each cup has uniform quality and performance characteristics. After molding, the cups undergo a curing process. This step is giving the menstrual cup its final properties like flexibility and durability.

Post-production, each menstrual cup should subjected to rigorous quality checks. These checks are in line with the standards set by ISO 13485. They ensure that every cup is free from defects, meets the required hardness specifications, and is biocompatible. Quality control measures may include visual inspections, leak tests, and material consistency checks.
