How to produce ventilator masks with liquid silicone injection molding machine?

The production process of the breathing mask is mainly the liquid silicone injection molding process, after the hot mold, hot mold to a certain temperature, the silicone raw material (AB component liquid silicone) is mixed with high temperature and high pressure through the liquid silicone injection molding machine, and the silicone products are molded and cured, that is, the silicone products are completed.

As a medical accessory product, the respiratory mask has high requirements, in addition to the material needs to reach the medical grade, its production environment requirements are also relatively high, it needs to reach the 100,000-level dust-free workshop, and the production qualification needs to meet the conditions of ISO13485 quality management system certification, and the general liquid silicone molding speed is slow.

Types of liquid silicone masks for ventilators.

Medical equipment with breathing masks, anesthesia masks are basically medical liquid silicone by liquid silicone injection molding machine processing, according to the different product production process, can be divided into full silicone mask, wrapped silicone mask, it is understood that the epidemic prevention of the ventilator mask, the application of large is the full silicone mask, especially the liquid silicone mask, liquid silicone mask.

Ventilators on the market include liquid silicone masks for medical anesthesia in the following categories:

1. Liquid silicone mask.

The full-body silicone mask is characterized by covering the mouth and nose, and patients can breathe through the mouth or nose, which is beneficial for patients who are accustomed to using mouth breathing during sleep, can avoid oral air leakage, and is suitable for patients with respiratory diseases such as COPD. Sex masks are more likely to leak air than other types of masks and can have an impact on drinking water and communication. If there is no severe nasal congestion and patients who use nasal breathing while sleeping, the following two types of masks may be considered.

2. Liquid silicone nose mask.

The liquid silicone nasal mask covers the nose and breathes through the nasal cavity, which has a wide field of vision, is simple and comfortable, and is widely used by general patients. It is easy to leak the mouth, and friends who are used to mouth breathing still choose masks that are more comfortable.

3. Liquid silicone nose pad mask.

This mask has less contact with the facial skin, is light and comfortable, breathes through the nose, has a wide field of vision, is better for people with claustrophobia, and can be used for those with mild snoring. Plug-in nasal pads, when the pressure is high, can have obvious irritation to the nasal mucosa, nasal septum deviation is not recommended for patients, mouth breathing patients are not recommended to use, through the mouth of patients can greatly reduce the efficacy.

It is reported that liquid silicone nasal masks and liquid silicone nasal pads are in great demand. The requirements of medical silicone devices for the production process and production environment, and various test reports of prenatal production equipment and production environment management all need to be verified on site in order to have manufacturing qualifications. Compared with traditional medical device raw materials, liquid silicone rubber has unique advantages, and liquid silicone injection molding machine is also an inevitable trend in the development of medical device raw materials in the future.
