Five key points in the molding process of liquid silicone products
Dec 29,2023 Hanast
In the production process of liquid silicone product molding process, in order to avoid product defects and control the cost of raw materials. Relative to the ambient temperature, the five factors of time, injection, weight, and mold have their own experience. Hanast will share with you below.
Silicone product molding process-ambient temperature
First, the set ambient temperature value must be achieved before the rubber can be injected. After the mold is released, the use of an air gun or an air outlet directed at the mold core should be minimized, thereby reducing abnormalities caused by temperature changes in the mold core. .
Silicone product molding process-time
The control time cannot be too short or too long. If the time is too short, the product will be half-cooked and unable to vulcanize. If the time is too long, the product will be too brittle or even deformed.
Silicone product molding process-injection
Injection of rubber is also very important. Compared with some molds, if the injection of rubber is not good enough, it will cause the product to be short of material. Products with too many holes in the mold must be placed at a speed that can keep up, preventing them from being damaged. It is already baked before being molded.
Silicone product molding process-weight
The weight of the material determines the size of the flash. If it is too heavy, the flash cannot be cut. If it is too light, the product will be short of material, so use a moderate weight.
Silicone product molding process-mold
For the maintenance of the mold, if the flash is stuck, you can use mold release water to spray it to benefit the mold, and it will be relatively easy to make a good mold release.
It can be seen from the above five factors of liquid silicone that a silicone product manufacturer must not only rely on excellent machinery and equipment to produce an excellent finished product, but also have professional and substantial operating methods and know-how to make excellent products.
