Injection The system is very important on mold designing, it is connected with plastic products sharp, dimension, injection molding machine and so on.


Injection system is guided the plastic inject to plastic mould from nozzle, it have forward pressure and heat function. It including hot runner and normal injection system.


Side lamp mould has adopted normal injection system: main spruce, subchanel, cold slug well and injection gate.


1.      Subchanel should be straight enough, should be short enough, cut the belt, and keep the shining Ra + 1.6-0.8mm.

2.     Think about The mold cavity number, based on the mold size design the cavity number, making the mould with symmetry

3.      When the products area is too big, then we should avoid the gate designed in gate, to devoid the injection unbalance.

4.      Should make the gate cut with ease; keep the products with good appearance.

5.      Design the Main spruce, avoid it inject the parts or core, stop the beating.

6.      The main spruce design should be prepare some area to keep the accurate.


Mould plate design: generally mould designed with outer loosing core, drive system used with slider angle pin, spring and hydraulic system.


The material we used for side lamp mould is PC, PC with high transparent to satisfy the light could through it clearly. 


Injection machine select should based on the material one mold needed.

During the machine selecting, we should pay attention to the machine screw diameter, injection weight, injection pressure and clamping force, important is tie bar distance, min. &max. Mould thickness.


Of course, we use plastic mold for produce side lamp should obey following requirements:


1.      Easy form tooling, easy for assembling, reduce the cost

2.      Reduce the Weight of side lamp products to cut the car weight, and then save the oil finally.

3.      Keep longer side lamp life and corrosion resistance.

4.      Assembling Parts save the space

5.      Beautiful, comfortable, good feel of the side lamp.

6.      The material I could be recycled, saving energy.


Above is in car making, also suitable for side lamp mould making.

As we export many sets of car parts mould, or customers are satisfied with our products. So we are confident we could service our customer’s high quality and high performance side lamp mould.
