HTV high-temperature vulcanized silicone rubber is a kind of silicone product, with excellent high and low-temperature resistance, ultraviolet resistance, radiation resistance, weather resistance, electrical insulation, high breathability, physiological inertia, low compression permanent deformation and fatigue resistance, etc.
Therefore, HTV high-temperature vulcanized silicone rubber is widely used in aviation, aerospace, electronics and electrical, light industry, machinery, construction, chemical industry, medicine, daily necessities, and other aspects, the following will give you a detailed explanation of the three high temperature vulcanized silicone rubber molding process.
According to the types of high-temperature liquid silicone rubber on the market at present, one is solid silicone and the other is liquid silicone. The molding of solid silicone can be divided into molding and extrusion molding, and liquid silicone is mostly injection molding.
Molding
Molding is also called hot pressing, that is, in the high-temperature mold add (double 25 or double 24) a silicone platinum vulcanizing agent of the compound through the plate vulcanizing machine pressure, high-temperature vulcanization molding.
The molding process is the production process of solid silica gel. The upper and lower two modules are combined, and a mold core is placed in the middle, so it is called the molding silicone rubber.
The main production process of molded silicone rubber products is the processing process of silicone rubber products formed by heating and pressurizing the silicone rubber raw materials in the closed mold cavity.
Usually, the silicone raw materials are evenly mixed into the mixing machine, and the mold is moved into the vulcanization molding machine.
Then the closed mold pressure, molding and curing or vulcanization, and then the release of silica gel products, this process is suitable for thermosetting materials processing.
The hardness of molded fumed silica gel is usually 30-70A (Shore hardness). In the process of rubber mixing products in the silica gel factory, the raw rubber is first added to the double roll rubber mixer or closed kneader.
Gradually added white carbon black, silicone oil, and other additives repeatedly refining. According to the different fillers and additives, the performance of silica gel is also different.
This process is relatively low cost, high yield, and widely used. It is used for monochrome silica gel products.
It can also be used in two-color and two-hardness products or multi-color and multi-hardness products, but the structure of the product is not flexible, or limited.
It can also be applied to plastic and metal packages, the same structure is not flexible, and the package has temperature requirements, the general requirement of the package to withstand 180 degrees Celsius without deformation.
The shape of the injection molding process determines the shape of the molded silicone products. Molded silicone products are the most widely used in the silicone industry at present.
Mainly used in the production of silicone industrial accessories, buttons, silicone gifts, silicone bracelets, silicone watches, key bags, mobile phone covers, silicone kitchenware, silicone mat, ice grid, cake mold, and so on.

Why is silicone a great molding material?
Silicone is a great molding material due to its flexibility, durability, and resistance to extreme temperatures and chemicals. It can capture fine details and complex shapes, making it ideal for intricate designs. Additionally, silicone molds are reusable, which makes them cost-effective for various applications, from crafts to industrial manufacturing. Its non-stick properties also facilitate easy demolding of finished products.
What industries use resin transfer molding processes?
Industries that use resin transfer molding, include the automotive and and aerospace industries.
How are rubber wristbands made?
Rubber wristbands are made by some substance called silicon or silicone that is placed into a molding space to shape it.
What is the difference Insert Molding vs Overmolding?
The general concepts of overmolding and insert molding are similar, but there are significant differences between the two processes.
How does silicone molding hold up over time?
http://users.lmi.net/~drewid/rubbers_faq.html if you the internet and srcoll down to silicone it will tell you everything, Silicone is the best for molds, costs are high and its very finicky so it;s good to understand the tricks of working with it, it hold up great if it;s the right grade.
What chemical processes are used to create plastic bottles?
Plastic bottles are produced by blow molding.
How is plastic used in molding processes?
Plastic is used in molding processes by heating it until it becomes soft and then shaping it into a specific form using a mold. Once the plastic cools and hardens, it retains the shape of the mold, allowing for the production of various plastic products.
What is injection molding simulation and how does it work?
Injection molding simulation is the process of modeling the plastic injection molding processes using computer software.The software allows the user to input various injection molding parameters such as material type, melting point, gate size and location, runner size and location, and part geometry.
