Thin wall container is very popular in market all over the world. typically, container with a wall thickness less than 0.6 mm is considered as "thin wall". Thin wall container features: thin wall, light weight, high yield, short turnaround period, so the mould requirements are very high.
Thin wall injection molding needs molding speeds 4-6S, so it requires a very good cooling system and high hardness in order to ensure the short cycle and the mold life. For such molding speeds, we should add water channel as more as possible, strengthen the water circulation. Usually we use chilled water. Besides, we always adapt with BeCu to help the mould cooling, because BeCu has good thermal conductivity.
As for the thin wall mould, the most important thing is to control the tooling precision. we always use high speed milling machine and some other high precision tooling machine to tool it, the dimension tolerance should be controlled within 0.05mm. And there will have many inserts so as to maintain the moulds, need very special air venting in the mould.
Regarding the steel for thin wall container mould, our mould steels are stainless steel. We use 2316 steel for thin wall mould core and cavity steel. After heating treatment, the thin wall mould steel hardness can reach to HRC 42-48.
Regarding the ejection system for thin wall container mould, we usually use air to blow off the cavity. It requires the parts demolding quickly and then use air ejection or air with stripper plate assistance.

Generally thin-walled plastic containers require materials with high fluidity , sufficient strength, so need plastic materials melt index (MFI) bigger then 40. (bigger MFI is better)
