< p> mold what are the requirements for the silicone product
s < / p> < p> of silica gel products production relies mainly on the molding, the mold what are the requirements for the silicone products?
< / p> < p> in order to ensure the quality of silica gel products mould manufacturing and production cost, the selection of the silicone mold material should has a good malleability, cutting machining, hardenability, hardenability and grinding, also should have little oxidation and decarburization sensitivity quenching distortion and cracking tendency.
< / p> < p> in the mold to the silica gel products when select material, economy this principle must be considered, as much as possible to lower the manufacturing cost.
Therefore, on the premise of meet the performance, first choose low price, you won't have to alloy steel with carbon steel, can use domestic material don't have imported materials.
< / p> < p> cold and hot fatigue is one of the main form of hot-work die failure, help the mould should have high resistance to cold and hot fatigue performance.
Mold in the process of work is in a state of repeated heating and cooling, make the cavity surface tension, pressure stress, the effect of surface crack and spalling, caused by increasing friction, obstacles to plastic deformation, reduces the dimension precision.
< / p> < p> products come out from the mould of the silicone buttons will be jointly and severally useless burrs, will need to be removed;
At present, in the industry, this process is completely done by hand.
< / p> < p> when the mold working temperature is higher, can make the hardness and strength, cause mould early wear or produce plastic deformation and failure.
Therefore, die material should have high tempering stability, resistance to ensure that the mold in the working temperature, has high hardness and strength.
< / p> < p> more exquisite silicone products, such as mobile phone silica gel set in zhe embellish too silicagelzrt.
For the study, researchers defined ZheRunTai as strategies to foster some social good, including programs that benefit community engagement, diversity, the environment, human rights and employee relations.
Our vision is to realize the tremendous potential of silicone cover by providing earbud accessories services that consistently meet our customers’ expectations.
silicone cover receives the updates through industry associations, internal legal counsel, regional associations and legal publications.
