Details determine success or failure, It is believed that everyone must understand this truth. This is especially true in industrial production, and even more so for the production of SMC molds, otherwise, the slightest error will be greatly affected, and the entire product quality will be affected later. Let's briefly talk about the details that need to be paid attention to in the production of SMC molds, which are as follows:


1. The silicone rubber material is in a fluid state before use, with good fluidity and filling properties. After being formulated, a rubber elastomer is formed through a cross-linking reaction, which can have greater elastic deformation, and the water in the original mold has no effect on its cross-linking reaction. The cross-linked silicone rubber has good sealing performance and does not adhere to the original mold and FRP. Using it as the surface layer material of the SMC mold can not only produce the shape of the work with high quality but also ensure smooth demoulding.


2. The specific SMC mold making method is: apply the prepared silicone rubber to the original mold several times, the silicone rubber layer should be more than 1mm thick (note the details, not too thick).


3. After the silicone rubber is cross-linked, an FRP layer with a thickness of about 3mm is formed on the silicone rubber.


4. After the glass fiber reinforced plastic is cured, cut the overall mold along with the divided unit blocks, and pay attention to simultaneously cut the glass fiber reinforced plastic layer and the silicone rubber layer when cutting. The connecting ribs are made between the unit blocks, and a slot should be set at the connecting ribs to ensure that the unit block molds are combined into a whole through the connecting ribs.


5. After the above work is completed, demould the glass fiber reinforced plastic unit block, then remove the silicone rubber layer, and put the removed silicone rubber block back into the glass fiber reinforced plastic unit mold immediately.


Generally speaking, the main process of making the SMC mold is as follows: Dust removal from the original mold → silicone rubber preparation → silicone rubber layer production → glass fiber reinforced plastic layer production → mold segmentation → connection rib production → demolding and assembly mold. Every link needs to be paid attention to details to ensure the results of the entire SMC mold.
