How to buy a good mould is always a big topic. According to my experience in IML mould area, I would like to share with you some important IML moulds inspection points. When you buy an IML moulds, you should pay attention to both of the product quality and mould quality.

IML moulds inspection key points mainly include two parts:
1.Mould inspection
--mould design quality control. In order to reach high quantity and high speed production requirement. IML mould have strict requirement to the cooling system, mould strength. Pay attention to them before the mould tooling.
--Steel hardness. Steel quality and steel hardness are relate to the mould life, mould precision, mould polish performance. So it will be better to let mold makers supply you steel certificate. Check if there is welding mark when you receive the moulds.
--Mould operating. Good mould should be ran automaticly, continuely without any problem. Also the cycle time is very import to be checked.
2. Product inspection
--Check the injection balance of each cavity by just injection half product. This method is very helpful to round IML containers.
--Check if there is any flash, burr, bubble, deformation on the product.
