Liquid Silicone Injection Molding Services
Silica gel is widely used in the market because it does not release toxic substances, has a soft and comfortable touch, and has good physical and chemical properties at high temperatures and low temperatures (-60c~+300c). There are a few other polymers that can match it.
Strong elastomer, better than rubber sealing, excellent electrical insulation, and resistance to chemicals, fuels, oil, and water, a good material to cope with adverse environments.
In the industry, such as oil seals, keyboard keys, electrical insulation materials, automobile parts, daily necessities such as pacifiers, artificial catheters, respirators, frog mirrors, leather shoes and sneakers, food containers, etc.
If you have any sliicone part need to production, just contact with us to get more experience.
What is difference between liquid silica gel and solid silica gel?
Liquid silicone
Liquid silica gel is a kind of solid high-temperature vulcanized silicone rubber. It is a liquid gel with good fluidity, fast vulcanization, safer and environmental protection, and can completely meet requirements of food grade.
Solid silica gel
Solid silica gel is a kind of saturated polymer elastic material, which has characteristics of high temperature resistance, cold resistance, solvent resistance, anti-sticking resistance, anti-sticking, electrical insulation, chemical resistance and has a wide application range.
1. Liquid silica gel and solid appearance
(1) As the name implies, liquid silica gel is liquid and has liquidity
(2) Solid silica gel is solid, with no liquidity!
2. The use of liquid silica gel and solid silica gel
(1) Liquid silica gel is generally used in baby products, kitchen products, and medical supplies, which can directly contact food and the human body.
(2) Solid silica gel is generally used in daily necessities and industrial miscellaneous parts and auto parts, etc., the application range is relatively wide.
3. Safety of solid silica gel and liquid silica gel
(1) Liquid silica gel is a high transparency and high safety food grade material, molding without adding vulcanizing agent and other auxiliary materials, sealed feeding molding.
(2) Solid silica gel is a transparent environmental protection material, forming needs to add a curing agent to speed up curing forming time, and open mold feeding molding.
4. Liquid silica gel and solid silica gel molding method
(1) Liquid silicone is injection molding liquid silicone rubber (LSR): full name for injection molding liquid silicone rubber, curing equipment for injection molding machine.
Injection molding machine has a technological process that is very simple, need not be the process of high-temperature glue ingredients, mixing, blanking, material and process, only one of the workers take products), high precision products (injection molding before all the manual program be replaced by A machine), high output (A/B glue mixing, under a certain temperature for A few seconds to shape), save, save electricity, save material and so on many merits, can produce all high-temperature glue production products! It is a mainstream silicone rubber material development in the next few years.
(2) Solid silica gel molding is a raw material that is a piece of solid, through the mixing machine mixing, the cutting machine is cut into products and injection molds the appropriate size and thickness, and then into the mold, pressure molding machine under a certain temperature molding. Demoulding and plastic products about the same, also need to clean the mold.
5. Liquid silica gel and solid silica gel products how to distinguish
Liquid silica gel transparency is high, with no odor, and the product has a glue injection mouth. Solid coarse pore silica gel transparent bottom, vulcanizing agent or another cover vulcanizing agent fragrance, a product without injection mouth

Tee Joint & P-Trap Mold Making and Injection Molding Production
Tee joint and elbow widely used in the liquid piping, air piping and medical equipment industry, It involves many different shapes, dimensions, and structures.
For ordinary tee joint, the structure is very simple, but for different countries and markets, the corresponding sizes and access methods are different.
However, in consideration of the problem of liquid and smell return, a more complex structure is completed on the basis of a set of molds, which still requires sufficient experience in design and production.
In our nearly five years of development, we have summed up more than 80 kinds of tee and pipe fitting product mold development experience.
Like the American standard ABS and PVC waste pipe, it involves the manufacture of ABS/PVC tee molds and tee injection molding of various sizes such as 1 inch, 1.5 inch, 2 inch, and 3 inch. We also have some manufacturing experience for PPR tee mold for our South Africa client(In order to help customers save mold development costs, on the basis of three sets of molds, we realized the production of 12 tee parts by replacing mold core and inserts). The most challenging thing is the three-way mold manufacturing and product production of small-sized medical equipment and automatic spraying system.
