• Why Wall Thickness is important for a defect-free plastic?

    Metal parts are often designed with thick walls, while plastic products should ideally maintain uniform wall thickness for uniform flow and less shrinkage as illustrated as below. For plastic parts, a gradual change in wall thickness or uniform wall thickness is recommended to reduce stress concentration and other potential issues. In this article we’ll explore what you need to know about the importance of maintaining proper wall thickness in Injection Moulding manufacturing process Maintain a wall thickness of less than 5mm because thick walls can lead to long cycle times and poor mechanical properties. Avoid large variations in wall thicknesses in order to simplify flow pattern and minimize variations in shrinkage that can lead to warpage. Avoid abrupt changes in wall thickness, as this can create stress concentration areas that may reduce a part’s impact strength. Wall thickness changes should have transition zones that reduce the possibility of stress concentrations, sinks, voids, and…

  • Plastic handheld massager

    Plastic handheld massager This is a two cavity family mold. The solid part is made of ABS and used as massager. The surface is mirror polishing. When you touch the part, you won’t feel the joint line at all. To remove the parting line on such a gloss face, precise machining is far from enough. It requires very skilled hand polishing as the joint line is aligned by hand. Whenever there is minor step between core and cavity, the joint line may be caused and hurt skin while massaging. What’s more ,the plastic wall is 30mm thick without sink at all. Normally, plastic part of this usual thickness requires pre-warp technology on the machining but our experienced engineer proudly solve the sink issues via adjusting the molding parameter. Since the surface is mirror polishing, we choose to use hardened S136. Though the steel is more complicate at machining than Nak80,…
