Silicone Menstrual Cup Making Machine Manufacturers in China

Silicone menstrual cup making machine sales coming more and more in these few years. As medical-grade silicone menstrual cup is became more and more popular in these years and the market is keep growing very fast due there are lots advantage for using silicone menstrual cups: Comfort,Reusability,Cost Savings,Leak Protection, Convenience,etc. So what kinds of silicone injection molding equipment are need for setting up the automated menstrual cup production line? As one of the leader supplier of menstrual cup making machines, we would like to show and introduce our industry 4.0 technologies menstrual cups manufacturing solution and soft cup manufacturing process with this article.

Design and Engineering of Liquid Silicone Menstrual Cup Manufacturing Machines




Customizd and well-designed menstrual cup making machine is one of the most important silicone injection molding equipment.
Low-maintenance menstrual cup machines ensure the hygienic manufacturing process for feminine cups. Reusable silicone period cup is made by liquid silicone rubber (LSR) with liquid injection molding (LIM)technology. It means the menstrual cups production process is big different comparing to traditional plastic injection moulding and will need the dedicated designed silicon rubber injection molding machine.

Below we will list some of the speical optimized technical specifications of menstrual cup manufacturing machines:

  • Special special mixing screw to ensure that A and B glues are fully mixed, ensure the uniform components, and effectively improve the repeatability and performance of the products.
  • Specially designed three small pieces to ensure accurate measurement during injection and pressure keeping.
  • A sealing ring and a wear-resistant ring are added to the screw tail to prevent silicone leakage from the screw tail.
  • Automatic cleaning system, which can simultaneously clean the mixer, screw and nozzle.
  • High response injection system and automatic switching function
  • Multi-stage precision electrothermal temperature control system
  • Closed-loop liquid barrel cooling
  • LSR special hydraulic water-cooled shut-off nozzle

Integrated Liquid Silicone Rubber Feeding Systems for Menstrual Cup Making Solution




LSR Silicone Menstrual Cup Injection Molding Mahine and LIM Material Feeding System

LSR silicone injection molding requires two different materials mixed with feeding ratio of a perfect 1:1 stable. There are lots advanced technology for menstrual cup manufacturing machines feeding system. With high precise designed LSR feeding machines is the key point for setting up an high-capacity menstrual cup production line.

Below are some of innovative features in menstrual cup making machines feeding system:

  • Closed-loop control metering and conveying system
  • Hydraulic continuous synchronous metering system
  • Digitization of equipment parameters
  • Closed-loop control of flow
  • Full-electric servo motor driven












Tooling and Injection Molding of Silicone Menstrual Cup Production




Precision designed mold for menstrual cups is a very important part of manufacturing process of menstrual cup making production line. we will provide a detailed overview of the tooling process, including mold fabrication and material selection. We will also explain the injection molding technique employed to manufacture the actual menstrual cups. Injection molding is a precise and efficient method that enables the production of consistent and reliable menstrual cups. Moreover, we will discuss the significance of mold temperature control and cycle time optimization in ensuring optimal manufacturing conditions and output.

LSR rubber generally has a low viscosity, so the mold filling time is very short. Even under very low injection pressure, the mold filling must be completed in a very short time. To avoid air entrapment, it is crucial to have good venting in the menstual cup injection mold.

There are many

  • Mold temperature control is very strict for menstrual cups
  • Customizable mold options for menstrual cups
  • The general width of the venting groove is lmm-3mm and the depth is 0.004mm-0.005mm.
  • The diameter of the mold sprue is usually 0.2mm – 0.5mm
  • The steel of the menstrual cup is special selected due cold runner and hot runner is very closed.
