technology and quality!
Long time chair mold life
a. Good plastic chair mold design, mould design is the most important step for manufacture a good plastic chair mold, reasonable mould structure, the suitable ejector system, injection system, cooling system, air venting system, guide system.
b. Choose the suitable steel, DIN1.***8 is very good steel for chair mold,but because of steel cost,customer use steel P*0 for chair mold.
c. Choose the best suitable tooling technical, Using big CNC milling tooling machine and mould press machine.
d. Mould assembling, the chair mold assembling must be very carefully, check connect of every mould plate; ejector pin, stripper, eject block or slider should move smooth.
e. Good technichian manual polishing or plus hard chrome plating keep the chair long time lasting shine.

Good temperature control for Chair mould
Let me introduce chair mould temperature control principle as follows:
1.The plastic chair mould cooling channel quantities as much as possible and the channel diameter as big as possible. the distance between central line of cooling channel and cavity surface is about ****5mm commonly, the distance of cooling channels is **5 times as cooling channel diameter.the cooling channel diameter is 8mm.
2. The distance between each cooling channel and cavity surface should be same.the cooling should be add if the plastic part thickess is not even.
3. The injection gate should be cooling very well.
4.If the cooling channel go through the insert and other connect mould parts, the important thing is sealing, to avoid any water leakage.
5. The cooling channel hole do not design to locate in the area where is the plastic chair Weld Line.
6. The cooling channel diameter according to the everage thickness of plastic chair,commonly,the cooling channel diameter should less than *4mm.

b. The plastic chair size should be as same as 3D product drawing.
c.Avoid By hand works on the parting area, otherwise you can never work out a perfect parting line.

Highly production efficiency chair mold
a. The best cooling system for product cooling fast
b. The plastic chair can drop automotive by mould ejector system
