Custom LSR Liquid Silicone Rubber Injection Mould/Molding Mold for Mentrual/Period Cup
Silicone menstrual cup is a type of reusable feminine hygiene product, which is also known as Diva Cups. It's a small, flexible funnel-shaped cup made of liquid silicone or silicone that you insert into vagina to catch and collect period fluid.
Diva Menstrual cups can be molded by compression mold and liquid silicone injection mold.
Compared with silicone compression mold, liquid silicone menstrual material is safer as LSR injection production environment is more clean and non contamination during the production. Liquid silicone molded diva cups quality is better and cmpression molded one, with minimal parting line, without flash.
LSR mentrual cups is made of biocompatipable liquid silicone. After molding, products also need to go through post curing, in order to eliminate the VOC (volatile organic compounds)
How to Use Silicone Menstrual Cups?
Liquid Silicone Injection Molding Processing
The finished tool is loaded into an advanced LSR-specific injection-molding press that is precision geared for accurate control of shot size to produce the most consistent liquid silicone rubber parts. LSR molding shares many similarities with conventional injection molding, but there are a few notable differences. Unlike thermoplastic resin, which is melted before injection, LSR is a two-part thermoset compound that is chilled before being injected into a heated mold and ultimately cured into a final part. Note that Protomold uses an automated meter mixing pump to assure the exact combination of the two-part compound; nothing is hand mixed. Since LSR is a thermosetting polymer, its molded state is permanent - once it is set, it can't be melted again like a thermoplastic.
Liquid silicone rubber is a free-flowing, shear thinning thermoset material that injects easily into a mold and is less prone to many defects like sink as compared to typical thermoplastic materials. However, LSR flashes extremely easily and into gaps as small as 0.0002 in. When designing a part for LSR, you should keep in mind best practices for tooling of standard plastic molds. Though the materials are different, the molds are constructed in a similar fashion.
Liquid Silicone Product Scope
1) Liquid silicone medical part, as like the capsule, laryngeal mask capsule, oxygen mask, protective mast, catheter, balloon, medical belt etc.
