Plastic meal boxes mainly used for packing foods, so it need to be heat resistant and non-toxic,and could meet the requirements of environmental protectionso, we have to choose proper plastic materials, such as food grade PP,PS,starch material,Plant fiber material etc., then mold should be signed with high polish, good injecting and cooling systems to make sure the boxes could be with good shap and finish.For enhancing the speed, normally we suggest to produce them on high speed injection machines.
As the wall thickness of the boxes is normally very thin, it's very important to design and make high-quality molds. An efficient mold cooling system can shorten the injection cycle and save more processing costs and time. We pay great attention to the mold cooling system and mold production stability. Our goal is to ensure customers run as little mold repair work as possible and be able to perform mass production efficiently and stably.

Designing about 2-3 different sizes of plastic meal boxes with the same lid could save the mold and production cost.
The thickness of the boxes is thin, so we need to design the mold with a good cooling system.
The materials of the boxes should be safe for hot food and meet environmental concerns.
To enhance production efficiency, you need to use a high-speed injection molding machine for production.
Using robots to pick up the parts during production can also enhance production efficiency.
Following our construction to install and use the mold, to make sure there's no any damage for the mold and less repair.
