Thin Wall is usually defined by portable electronic parts with a wall thickness of less than 1 mm. For large automotive parts, Thin Wall can be 2mm. Thin-walled molding products require changes in processing technology: higher pressure and speed, shorter cooling time, changes in ejection and gate arrangement.

The following are the requirements of thin-wall injection molding to injection machine.

Hydraulic injection machine for thin-walled injection molding has a pressure accumulator, which can drive injection and clamping frequently. In order to withstand the high pressure of the injection machine, the minimum clamping force must be 5-7 tons/inch. 
In addition, when wall thickness decreases and injection pressure increases, large formwork helps to reduce bending. The ratio of the pull rod of the injection machine to the thickness of the mold plate is 2:1 or lower. 

As for the injection volume, the large diameter barrel is too large. The recommended injection volume is 40%-70% of the barrel capacity. In this way, the total molding cycle of thin-walled products is greatly shortened. It is possible to reduce the minimum injection volume to 20%-30% of the barrel capacity. 
Be very careful during injecting, because for materials, small injection volume means that materials stay longer in the barrel, which will lead to a decline in product performance.
