takeaway: sheet in the process of molding, cooling, shrinkage occur inevitably. Different materials different shrinkage rate. So how do we' Is the negative pressure vacuum molding machine 】 In the production of control shrinkage rate? Union star mechanical small make up to introduce.

shrinkage rate is actually refers to the Is the negative pressure vacuum molding machine 】 In a deformation in the process of production, time is a sheet forming after ejection product size discrepancy in cooling at room temperature.

in general, the Is the negative pressure vacuum molding machine 】 In the process of production, shrinkage has the following several kinds of pattern:

mold temperature is low, the shrinkage rate will be smaller. Aluminum mold configuration cooling pipe is a kind of very good method of shrinkage rate control.

the product shape complex, shrinkage rate will be smaller, in the process of contraction, contain more of each direction.

product shrinkage of the horizontal shrinkage of small vertical direction.

material ratio of different materials, different shrinkage rate, so can't simple with a single material shrinkage rate resolution, is also a test for production experience. We in the design of the Is the negative pressure vacuum molding machine 】 Will be given the shrinkage rate, when the mould in the process of equipment debugging in the debug to satisfactory results.

summary: above is the [au star machinery small make up to introduce Vacuum forming machine 】 In the production of aseptic packaging related content. Other information, please continue to pay attention to this site to understand.
