Today, more and more housewives are using plastic containers for food or fruit storage. This lead to many more people engaged in food package products producing. Thin wall food containers and thin wall buckets are becoming popular used in daily life.
 
For many new beginners, they do not have technical skills of injection molding. So here we will introduce some tips to judge a good thin wall mould.
 

1. Mould design inspection. There’re many designers they do not have experience of making a mould, so they cannot take everything into consideration. Few days ago, a Turkey customer came to me and told me the mould they presently using has too much cooling time. When our engineer studied their mould drawing, we found that the cooling line did not cool the products. Then our engineer drew a rough drawing to suggest them with new design to shorten the cooling time. This story is telling that a good design really plays a very important role, a good mould design really can reduce the cycle time so to save production cost.

2. Mould steel selection. Thin wall moulds usually working under big pressure and high speed, so the steel should use vacuum hardening steel with higher HRC. Aero Mould generally us S136 stainless steel for core and cavity, with HRC 48-52.

3. Hot runner selection. Thin wall mould requires hot runner to make raw material melt and flow faster, so to reduce cycle time. If the hot runner is bad quality, it’s really a very complicated problem during production.

4. Injection molding machine condition. A high speed IMM shall use for fast production. And make sure the mould is cooperating perfect with the machine.
