The micro gear motor includes plastic parts such as plastic casings, plastic gears, etc., motors, gear shafts, bearings and so on. After the design stage,we enter into mold making stage. Before making plastic gear molds, we need to perform DFM analysis.
1.Why do we make a DFM report before making a plastic gear mold for a micro reduction gear motor?
3.Before making the DFM, if the conditions allow, we will conduct mold flow analysis on the plastic gear, and write down the results on the DFM.
The designers should analyze and optimize the parts structure. For example, they have to consider whether it is necessary to change the tolerance of the demoulding slope of the rib position of the plastic gear, whether it is possible to change or cancel some structures that cannot or are not conducive to demoulding, whether it is reasonable for the thickness of the glue position, and whether it is conducive to injection molding.
