Silicone Compression molding is one of the first types of production processes that has been around since the early days of the rubber industry and is commonly used to create vulcanized silicone rubber prototypes, products, and components.It is one of the oldest methods still used to mold rubber parts.
Silicone compression molding is the process of molding silicone rubber into a desired shape using a mold. The silicone rubber is placed into the mold in its uncured state, and then heat and pressure are applied to cure the rubber and form it into the desired shape.
We use two types of raw silicone materials in this process, precipitated silicone rubber and fumed silicone rubber.
Precipitated silicone rubber is a type of silicone rubber that is made by precipitating a silicone polymer from a solution. And Precipitated silicone rubber can pass FDA(American Food and Drug Administration) which is a public standard widely used in USA.
Fumed silicone rubber is a type of silicone rubber that is made by fuming silica with hydrogen chloride. And Fumed silicone rubber can pass LFGB(Food and Commodity Ordinance of Germany) which is a public standard widely used in Europe.
All precipitated silicone rubber and fumed silicone rubber are food grade, and we can offer SGS test report to prove it. We choose the the right materials according to your requirements and standard.
The machine used for compression molding of silicone rubber is similar to that used for molding thermoplastics. In both cases, there must be mold plates, a mold cavity, alignment bushings and pins, and a place to inject the uncured material.
However, compression molding is more cost effective than injection molding, which is typically used with thermoplastics or TPEs. Compression molding is more economical to use with elastomers such as NBR, SBR, EPDM, etc.
One of the main benefits of using silicone compression molding is that it allows for intricate designs and shapes to be created. This is due to the fact that the silicone material used in this process is very pliable and can be easily molded into any shape or size desired.
Additionally, once the mold has been created, it can be reused multiple times in order to create identical products each time.
Another benefit of this type of manufacturing process is that it is relatively quick and easy when compared to other methods. This makes it ideal for those who need to produce large quantities of a product in a short period of time.
In addition, because the mold can be reused, there is no need to create new molds each time a production run occurs – saving even more time and money.
Overall, the molding process provides manufacturers with a versatile and efficient way to create products quickly and easily. If you are looking for an alternative manufacturing method, this may be the perfect solution for you!
Silicone Compression Moulding process is used to manufacture silicone rubber products in many fields:
Silicone Compression Molding provides high–volume production with consistent quality at relatively low cost. It also has excellent dimensional stability and can produce products with very intricate detail.
JUTION SILICONE has been using silicone rubber compression molding process since its establish at 2007, now we have 20 sets of compression machines, from 80T to 1000T, we can produce wide range of silicone rubber products according to your requirements.
