The food-grade silicone necklace features a detachable pendant design

Design concept and goals

Safety and comfort: Made mainly of food-grade silicone, it ensures that the necklace is safe and non-toxic when adhering to the skin, and will not cause adverse reactions such as allergies. At the same time, the detachable pendant design should ensure that it does not cause scratches or discomfort to the skin during wearing and replacement, providing a comfortable wearing experience.

Personalization and diversity: Meeting users’ pursuit of personalization, users can freely change the pendant according to different occasions, moods or clothing combinations, making a necklace present various styles and shapes, and increasing the practical value and fun of the necklace.

Convenience and durability: The design should be simple and easy to operate, allowing users to quickly remove and replace the pendant. At the same time, the connection part between the necklace and the pendant should be firm and durable, capable of withstanding multiple replacements without damage, ensuring the service life of the product.

Structural design

The main design of the necklace

Silicone chain: The necklace chain is made of food-grade silicone, which is soft in texture, elastic, fits the neck skin well and gives a comfortable touch. The thickness of the chain can be adjusted according to the design requirements. Thinner chains appear exquisite and elegant, and are suitable for matching with small pendants. Thicker chains are more fashionable and individualistic, and can be paired with larger or uniquely shaped pendants.

Clasp design: Appropriate clasp is set at both ends of the necklace to facilitate users’ wearing and removing of the necklace. The connecting buckles can be common ones such as spring buckles and lobster buckles, but it is necessary to ensure that they are firmly connected to the silicone chain and will not fall off easily. Meanwhile, the material of the connecting buckle can also be selected as food-grade material that matches silicone to ensure overall safety.

Design of the pendant interface

Slot interface: A slot is designed at a specific position on the necklace chain, and a corresponding clasp is set on the pendant. When it is necessary to replace the pendant, the user only needs to align the pendant’s clasp with the slot and press it gently to complete the installation. When disassembling, pull the pendant outward with a little force, and the buckle will come out of the slot. This interface design is simple and easy to use, and the connection is firm. For example, similar to the splicing interfaces of some children’s toys, the connection and disassembly of components can be achieved through simple clamping.

Magnetic interface: By taking advantage of the magnetic principle of magnets, magnetic components are respectively installed on the necklace chain and the pendant. When the pendant approaches the necklace chain, the magnetic components will automatically stick together, completing the installation of the pendant. When disassembling, just gently pull the pendant apart with force. The magnetic interface is easy to operate and has a certain adsorption force, which can ensure that the pendant will not fall off easily during wearing. However, attention should be paid to the selection of the magnet’s strength. It must ensure a firm adhesion while not being too strong to make disassembly difficult.

Rotary interface: A threaded interface is set on the necklace chain, and the pendant is equipped with a corresponding rotating part. The user completes the installation by rotating the pendant to make it closely combine with the interface on the necklace chain. The pendant can be removed by rotating it in the opposite direction. This interface design is relatively stable and suitable for some larger or heavier pendants.

Key points of pendant design

Material matching: The material of the pendant can be diverse. Besides food-grade silicone consistent with the main body of the necklace, it can also be matched with metal, gemstones, wood and other materials. For example, the frame of the pendant is made of metal and then filled or wrapped with silicone to form a unique shape; Or set some small gemstones on the silicone pendant to enhance its magnificence. However, it is necessary to pay attention to the harmonious combination of different materials to avoid any jarring or discordant feeling.

Shape and Design: The shape of the pendant can be innovated according to personal preference and design theme. Common shapes include circles, squares, hearts, etc. They can also be designed into interesting forms such as animals, plants, and letters. For instance, design a silicone pendant in the shape of a cat. The body part of the cat can be made of silicone, while the eyes, nose and other parts can be decorated with metal or gemstones. It is both cute and creative.

Color selection: Food-grade silicone can be mixed into a wide variety of rich colors. The color selection of the pendant should be in harmony with the main body of the necklace and the overall matching. You can choose bright and vivid colors to enhance the visual impact of the necklace. You can also choose soft and elegant colors to create a warm and refined atmosphere. For example, in summer, one can choose fresh colors such as blue and green, which give people a cool feeling. In winter, warm colors such as red and orange can be chosen to add a festive atmosphere.

Manufacturing process

Silicone rubber molding

Mold making: According to the designed shapes of the necklace and pendant, make the corresponding molds. Molds can be made of materials such as silicone, metal or plastic to ensure the precision and surface smoothness of the molds, so as to guarantee the quality of the products after molding.

Injection molding or casting: The prepared food-grade silicone raw materials are injected into the mold, and the silicone is formed through an injection molding machine or casting. During the molding process, parameters such as temperature, pressure and time should be well controlled to ensure that the silicone rubber is fully filled in the mold and avoid defects such as bubbles and material shortage.

The connection part between the pendant and the necklace is made

Metal accessory processing: If the design involves metal accessories such as connecting buckles and interfaces, metal processing is required. Metal materials can be processed such as cutting, drilling and grinding by using lathes, milling machines and other equipment to produce metal components that meet the design requirements.

Assembly and debugging: Assemble the formed silicone necklace body, pendant and metal accessories. During the assembly process, it is necessary to ensure that the connections between each component are firm and the interfaces are smooth. After assembly is completed, conduct debugging and inspection to ensure that the necklace and pendant function properly and are comfortable to wear.

Quality control and testing

Visual inspection: Check whether the appearance of the necklace and the pendant is smooth and free of flaws, whether the color is uniform and consistent, and whether the shape of the pendant meets the design requirements.

Functional test: Test whether the replacement function of the pendant is smooth, whether the interface is firm, and whether the connection buckle of the necklace is reliable. Multiple disassembly and replacement operations can be carried out to observe whether there is any loosening or damage.

Safety inspection: As food-grade silicone materials are used, it is necessary to ensure that the product complies with relevant safety standards. Chemical composition detection can be carried out to ensure that there are no harmful substances in the silica gel. Meanwhile, check whether the metal accessories have undergone anti-rust and anti-allergy treatments to ensure the safety of the products.

Usage and Maintenance

Instructions for Use: Provide users with detailed instructions on how to wear, replace the pendant correctly and maintain the necklace. For example, remind users to handle the pendant gently when removing or replacing it to avoid excessive force that may damage the interface. During the wearing process, be careful to avoid the necklace coming into contact with sharp objects to prevent scratching the silicone surface.

Cleaning and maintenance: Regularly clean and maintain the necklace. You can use mild soapy water or a special silicone cleaner to clean it, then rinse it thoroughly with clean water, dry it and store it. Avoid cleaning with organic solvents or strong acid or alkali solutions to prevent damage to the silicone and metal parts.
