LSR injection molding technology

Introduction

LSR injection molding (Liquid Silicone Rubber) is a new and highly efficient silicone rubber moulding method developed at the end of the seventies, which consists of two key components: LSR and LIM. After years of research and development, more and more companies have recognised and adopted LSR injection molding process to produce silicone rubber products, ushering in a new path of high efficiency, high quality and low cost production in the silicone rubber processing industry.

Compared with the traditional hot curing (HCR) moulding process, the use of LIM process to produce rubber products has the advantages of saving time and energy, eliminating the post-treatment process, high product yield, and low comprehensive cost (saving about 40%). Has been part of the silicone rubber processing enterprises using LSR and process production of silicone rubber products, used in new energy, electrical and electronic, mechanical parts manufacturing, aerospace parts, medical, maternal and infant, adult, kitchenware and other fields. Therefore, LSR injection molding has a better market application prospect.

Injection moulding liquid silicone rubber-the full name of the LSR injection molding process

Silicone injection moulding process is very simple and efficient.

1.Simple procedures
The production is no need for high temperature rubber process in the ingredients, refining, cutting materials, add &mix materials and other manual processes, only a worker to take the product can be.

2.High product accuracy
LSR injection molding process before all the manual procedures are all replaced by automated machines

3.High yield (A/B rubber mixing at a certain temperature in dozens of seconds under the molding)
Save people, save electricity, save materials and many other advantages, can produce all high temperature rubber production products!And is a mainstream silicone rubber material development in the next few years.

4.Mold Removal
Once the mold has cooled, it's opened up and the new LSR component is peeled off. Then, depending on the final application, the part might have additional finishing processes, like trimming, cleaning, or surface treatments.

 5.Quality Control
We put in place stringent quality control measures because LSR parts have really demanding applications. This includes things like checking the parts are the right size, doing some mechanical testing, and making sure they meet the required specifications.

What are the advantages of liquid silicone injection moulding?

Our baby care LSR injection molding case:

1. Liquid silicone is one of the best materials around. It's really clear, strong, stretchy, doesn't fade in sunlight, the tensile strength of LSR can be more than 2,000 psi, and it exhibits exceptional tear resistance, up to 400% elongation at break.
2. LSR can operate effectively in a range from -55°C to +300°C,which isstable at high temperatures, doesn't absorb water, is breathable, and can resist heat and weather. It's also easy to work with and you can see through it easily.
3. LSR injection molding processis great for saving time and energy, and you don't need to do any post-treatment.
4. Plus, you can get a high yield and it's pretty cheap overall (saving about 40%). It's easy to use in a production environment, and you can use robots to automatically demould the products.
5. Environmental Resistance: LSR components can handle exposure to oils, solvents and other chemicals, which is why they're often used in car, automotive and science electronics applications.

Liquid silicone injection production industry application technology

Liquid silicone needs to be produced by injection machine, more and more widely used in baby products, medical supplies, electronic products, aerospace, new energy and so on, a kind of A/B rubber is mixed evenly and directly injected into the mould cavity heated to a certain temperature vulcanization molding, mainly depends on what you use in the product above. General liquid silicone after vulcanisation in the use of moulding, but also can be used as a kind of filler, such as electric power insulation filler, or adult beauty industry with liquid silicone filler, or as a cosmetic additives within the use.
