What is plastic material shrinkage? (It related to tolerance on the drawing)
Plastic moulding shrinkage is the contraction of a plastic moulding as it cools after injection. Most shrinkage occurs in the mould during cooling, but some shrinkage occurs after ejection, as the part continues to cool. After that, the part may continue to shrink very slightly for several hours or even days until the temperature and moisture content stabilise.
All polymers have different shrink rates depending on many factors. These include amorphous or crystalline materials, cycle times, temperatures, mould design, part shape and wall thickness.

Today is Dragon Boat Festival.It's in every may ,5th of the lunar calender.It falls on 25th.June this year. People wil have one day holiday to memory this traditional festival. Blessing each other "Happy Dragon boat festival" ! People would like to say "Happy Zongzi holidays!" because to have "Zong zi" is a sign of this festival .Briefly speaking ,"Zong zi" is a kind of holiday food .Made of rise and traditional ingredients.

If you travel in China especially from Ningbo city to Shanghai and Jiangsu province ,you can buy some on High-speed service area.

Hydraulic power unit plastic oil tank material PP ? PE? or steel ?

Because PP has better high temperature resistance than PE .It won't be a problem under normal use .But when the oil temperature of a high-power machinery is raising over 90℃, the PP plastic oil tank would have a better performance than PE material ( it can reach to 100 ℃) .

While ,PP has it's advantage ,but PE material has a better cold resistance performance than PP（do not exceed -20 ℃）while PP is （-5 ℃ ~-15 ℃）.If it's used in a very cold place ,like in Siberia （frigid zone or close ），it's better us steel oil tank . It could stand -80℃~ 500℃ temperature. If used in North/South temperate zone ,it's better to use PP material hydraulic power pack plastic oil tank. If it's colder but the working temperature won't exceed 90 ℃ ,using PE is ok too . It might have a risk under high temperature if it's nearly reached to 100 ℃。

But steel tank do not have all the plastic oil tank's advantage .
