Silicone products can be divided into the following categories according to the production process
Extruded silicone products: silicone sealing strips, wires, cables, etc.
Coated silicone products: silicone backed with various materials or films reinforced with textiles.
Injection-pressed silicone products: various model silicone products, such as small silicone toys, silicone mobile phone cases, medical silicone products, etc.
Solid molded silicone products: including silicone rubber miscellaneous parts, mobile phone cases, bracelets, sealing rings, LED light plugs, etc.
Dip-coated silicone products: including high-temperature steel wire, fiberglass tubes, finger rubber rollers and other products.
Calendered silicone products: including silicone rubber rolls, table mats, coasters, window frames and other products.
Injected silicone products: including medical supplies, baby products, baby bottles, nipples, auto parts, etc.
The main reasons why silicone products are difficult to demould may be as follows:
The mold design is unreasonable and the release angle is not considered.
Silicone products are too sticky and have low plasticity, making them difficult to remove.
Silicone products have complex structures and many vacancies.
Not using a suitable release agent or not using enough.
The silicone is not completely vulcanized and is not fully cured.
The timing of stripping is not well controlled.
Other factors include the mold being used for too long, the mold being used too many times, etc.
