　　What do I need to do before opening the mold?

　　First, confirm the product drawing

　　First of all, let the customer provide the product drawings, before the mold opening designers and production personnel need to further confirm the drawings, to see whether the material and proportion used are exactly the same as the design scheme, if there is a deviation problem, to adjust in time.

　　Second, determine whether special processes are used

　　Before starting production, you need to look at whether the material used needs some special process for surface treatment, no matter what kind of mold, if there is a problem with surface treatment, then it is difficult to produce high-quality products.

　　Third, test and trial

　　When the mold opening work is completed, it is necessary to carry out quality testing, if the sample produced does not meet the needs or standards, of course, if the ideal effect is achieved, it can be mass-produced, only in this way to ensure that the mold can play a key role.
