Whether to choose solid silicone or liquid silicone to produce silicone trademarks should be determined according to specific needs: if you pursue low cost, simple structure and wear resistance, solid silicone is preferred; if you need high precision, soft touch or complex structure, liquid silicone is more suitable. The following is a detailed analysis of the characteristics of the two materials and applicable scenarios:
Solid silicone: a balance between low cost and wear resistance
Material characteristics
Molding method: Molded by high-temperature compression vulcanization (160-200℃), suitable for mass production of simple structure products.
Cost advantage: The mold cost is low and the production cycle is long, but the scraps can be recycled and the overall cost is low.
Physical properties: High pressure resistance and wear resistance, suitable for scenarios that need to withstand external forces.
Applicable scenarios
Industrial seals: such as O-rings and gaskets, which need to be resistant to high pressure and wear.
High temperature resistant kitchen utensils: such as baking molds and spatulas, which can withstand 250℃ high temperature and low cost.
Consumer electronic accessories: such as buttons and protective covers, which have high hardness requirements.
Limitations
It is difficult to achieve complex structures or high-precision molding, and the linear shrinkage rate is large (which may affect dimensional accuracy).
Liquid silicone: an ideal material for high precision and soft touch
Material properties
Molding method: liquid injection molding (LIM), which is quickly cured (120-180℃) after mixing two-component liquids, suitable for precision structures.
Physical properties:
Soft touch, excellent elasticity, suitable for scenes with direct contact with the skin.
Linear shrinkage rate ≤0.1%, can accurately replicate product dimensions, and meet high precision requirements.
High temperature resistance (-50℃ to 250℃), chemical corrosion resistance, and biocompatibility is FDA certified.
Environmental protection: no waste generation, high degree of automation, and short production cycle.
Applicable scenarios
Maternal and child products: such as pacifiers and teethers, which require soft touch and safety.
Medical devices: such as catheters and artificial organs, which require high precision and biocompatibility.
Precision electronics: such as waterproof seals and sensor packaging, which require microstructure molding.
Silicone trademarks: If three-dimensional graphics or complex shapes are required, liquid silicone can achieve finer textures and edges.
Limitations
The mold cost is relatively high, suitable for small batches or high value-added products.
Decision-making suggestion: Choose according to needs and give full play to the advantages of materials
Scenarios for choosing solid silicone:
The trademark structure is simple (such as a flat pattern).
Need to control costs and have high requirements for wear resistance.
The production batch is large and sensitive to mold costs.
Scenario for choosing liquid silicone:
The trademark requires three-dimensional graphics or complex textures (such as the fine edges of the brand LOGO).
Need a soft touch (such as trademarks on underwear).
High precision requirements (such as trademarks of smart wearable devices integrated with electronic components).
