Demoulding
The vulcanized liquid silicone rubber is easy to adhere to the metal surface, and the flexibility of the product will make it difficult to demould. The high temperature tearing strength of LSR can make it demould under general conditions, and even larger products will not be damaged. The most common demoulding technologies include demoulding of formwork, demoulding pin and pneumatic demoulding. Other common technologies include roller scraping, export plate demoulding and automatic mould controlling.
When using the demoulding system, it must be kept within the high accuracy range. If the gap between the push pin and the guide pin sleeve is too large, or the gap between the parts becomes larger due to long-term wear, it may cause glue overflow. The effect of inverted cone or mushroom top marketing is very good because it allows the use of larger contact pressure, which is convenient for improving the sealing quality.
