What is the cause of the deformation by liquid silicone products
Liquid silicone products deformation shrinkage reason and the solution 1, liquid silicone rubber silicone rubber skeleton temperature package of the base material is easy to cause deformation in the heating process.
Especially obvious in these plastic PC/nylon.
Sulfide liquid silicone molding temperature between 110 ℃ ~ 150 ℃, generally small sprout life advice package plastic deformation temperature of the substrate, embedded objects must be at least above 150 ℃.
Solution: replace the silicone bag plastic base material, it is suggested that using high temperature resistant materials.
2, liquid silicone injection base material by uneven pressure lead to deformation of silica gel pack glue product embedded objects need to be in the mould is stable and reliable positioning, sealant to mold under pressure, so the mechanical parts must be balanced.
Solution: adjust the mechanical parts of the embedded object.
3, liquid silicone product structural design is unreasonable silicone shrinkage than embedded objects (generally
As far as possible big, silicone rubber products section structure wants even, not local too thick or too thin.
The solution: optimizing the structure of liquid silicone products.
