◆ as a non-toxic, heat-resistant and highly restorative thermosetting material, liquid silica gel (LSR) has a growing demand in the market in recent years. Because LSR is safe and environmentally friendly, can completely meet the requirements of edible grade, and has the advantages of high temperature resistance, low temperature resistance, electrical insulation, tear strength, weather resistance, etc., LSR is currently mainly used in the field of infant, medical and electronic products, such as infant pacifier, respiratory mask, mobile phone cover, watch belt, etc.

Liquid silica gel (LSR) injection molding
Liquid silica gel is a two-component liquid material, which is composed of component A and component B. The ratio of the two is controlled to 1:1 by a quantitative device, and then they are fully mixed by a static mixer before entering the plasticizing system.
However, due to the high cost of liquid silica gel materials, the solidified products can not be recycled. In the molding process, it is necessary to equip with a metering feeding system, an injection molding machine with a modified material pipe group, as well as a special heating mold and a high temperature controller, which all make the production cost of liquid silica gel injection molding higher.

Yizhimi liquid silica gel (LSR) special injection molding machine
In order to provide customers with liquid silica gel (LSR) solutions with high cost performance and high return on investment, yizhimi has launched a special injection molding machine for liquid silica gel. Compared with the general modified injection molding machine, LSR special machine can adapt to the production of more silica gel products of different sizes and types, and improve the product qualification rate and safety protection.
Flexible production and wider applicability
Yizhimi LRS special machine increases the mold capacity space, and the width of un120lsr guide pillar internal distance is increased to 460mm, which can realize the installation of larger size mold, facilitate the design and production of silica gel products of different sizes by customers, improve the utilization rate of the machine to a greater extent, and reduce the equipment investment cost.
It can adapt to different sizes of liquid silica gel products (liquid silica gel cupping pot)
Improve the repeat precision and quality of LSR products
Due to the low viscosity and easy leakage of silica gel raw materials, yizhimi LSR special machine adopts silica gel special plastic components.
2. The water-cooled constant temperature barrel keeps accurate temperature control, which can avoid the pre crosslinking and curing reaction of silica gel.
3. Water cooled pneumatic shut-off nozzle to prevent silica gel leakage and mold temperature transfer to the nozzle, resulting in a well mixed silica gel curing reaction.
4 special mixing screw to prevent leakage of silica gel, ensure full mixing of glue a and B, ensure even composition, and improve the repeated accuracy and performance of products.
5 special design of three small parts can ensure the accurate measurement in the process of injection and pressure maintaining.
6. The vacuumizing procedure and page shall be used together with the vacuumizing mold to improve the exhaust performance of the mold and prevent the defects such as lack of material and burning caused by trapped gas.
7. Add sealing ring and wear-resistant ring at the end of screw to prevent leakage of silica gel from the end of screw, resulting in waste of raw materials and unstable injection.
Humanized operation
1. The air gun interface is reserved at the operation side, and the pneumatic interface of silica gel feeder is reserved for quick connection.
2. The mold heating temperature control is built-in, which realizes visualization and is convenient for customers to adjust the temperature. Each group of heating is equipped with a separate socket for customers to use.
3. Special protective device for silica gel machine to reduce product pollution and easy to clean.
