introduction:Case 1,CLIPdesign: This product is a fixedUDisk retractable clip。As shown in the following picture,The deformation requirement at the mark is strict,The deformation of products produced in the past is often too large here, Our engineers consider setting the predeformation in one direction at the time of mold design,And product deformation cancel each other,To ensure that the product meets the requirements。 The question is how much of this predeformation,How is the direction,Didnt know before the design,If the predeformation is too large,In the future, the product may reverse deformation。 With the help ofMOLDFLOWsoftwareFLOW COOL WARP

introduction: The ram has a planer﹐Planer for linear reciprocating motion﹐It got its name from the shape of the blade holder at the front of the ram。The shaper is mainly used for planing the plane on small and medium workpieces in single piece small batch production﹑Forming surfaces and grooves。The main movement of small and medium-sized shaper(Sighting machine)Most of them use crank rocker mechanism(See crank slider mechanism)drive﹐Therefore, the speed of movement of the ram is not uniform。Large shaper machine mostly adopts hydraulic transmission﹐The ram basically moves at a constant speed。The return travel speed of the ram is greater than the working travel speed。Due to the use of single-edge planer machining﹐And do not cut when the ram returns﹐The productivity of shaper is low。machine
