DFM stands for Design for Manufacturing, it is a process/document discuss how the manufacturer going to make/manufacture/produce a product. Here discuss a DFM for a injection molding mold, which generally consisted of following elements: Plastic part design review (2D/3D) Collect and study the purpose of the plastic part (for appearance or functional of assembly, the… Continue reading

E-3-Engineering Phase

The process in the Engineering Phase shall be conducted with the approved drawings, BOM, Functional Description, and Assembly Guidance…etc. serving as input. This phase has 2 main objects, define the manufacturing process and lunch the component/sub-assembly/product mass production. The following engineering activities should be executed and the associated documentation approved in this phase. EvaluationTo plan… Continue reading

D-10-IMM Evaluation

The best order is a single part with crazy qty. requirement, manufacturer only need to do same thing every day and keep making money. To meet the order’s requirement, manufacturer needs to prepare a big land/plant full of same equipment and molds. It means all equipment have same model/specification/even manufacturing date, so does the molds…. Continue reading

D-7-Confirmation before Injection Molding Process

Molding process preparation includes 3 aspects: raw material, mold, equipment (such as injection molding machine (IMM), temperature controller, process monitoring machine…etc.), they shall work with each other properly in order to produce good parts. At least but not limited to following items must be checked to confirm if the preparation had been done properly, it… Continue reading

D-6-Molding Parameters

Here discuss molding parameter settings and output on the IMM which mostly considered during injection molding process. The molding parameters above are machine inputs. The following are the outputs from the machine, which are a result of the settings of the molding parameters as available on the molding machine screens.

D-4-Cavity Monitoring System

Plastic part with consistent quality and behavior can be produced with consistent/stable mold status, molding process, and raw material. During the injection molding process, the melt plastic will be injected into the mold with a series mechanical movement of injection molding machine (IMM). This leads to the mold inside environment changes accordingly, in which the… Continue reading
