Thin wall container is very popular in market all over the world. (Thin wall container is generally refers to the container which wall thickness is about 0.4mm-0.8mm) .

Our factory is very professional in thin wall food container moulds manufacturing. every year, many customers come to us inquiry about the mould for thin wall container. After making many thin wall containers mould, we found good solution for such thin wall container.

Why thin wall containers are so difficult to molding?

Generally, during injection molding, thin wall container easy to appear uneven wall thickness and as the wall thickness is too thin, it needs high speed and high pressure injection, so the machine should be bigger than machine for general product, it is not because of its mould size is bigger or it needs big injection weight, it just because it needs high injection pressure, so the clamping force should be big.

Why we can produce a good thin wall container mould?

As to thin wall product mould, the mould dimension should be controlled precision. For such product, we always use high speed milling machine and some other high precision tooling machine to tool it, the dimension tolerance should be controlled in 0.02mm.

Regarding the ejector system for thin wall container mould, we usually use air to blow first, let the container not stick to the core and then use double ejector plates drived by hydraulic cylinders to ejector the product off the mould. As the container is too thin, so we generally don't use ejector pins, because ejector pin will easy lead to product deformation.

Cooling system is also very important to such thin wall product, just as I stated above, for such product molding, it needs high speed and high pressure. So the mould temperature will be high, it is very important to control the mould in low temperature, so we should add water channel as more as possible, and it should be near the product surface. Besides, we always adapt with BeCu to help the mould cooling, because BeCu has good thermal conductivity. Even though, the price will be much high than mould without BeCu, but the good cooling will help make the product very beautiful.
