Applications :

Electronic key products of mobile phone; mask material; baby product,baby nipple/teat, babypacifier,baby toothbrush

Operation Of Injection molding :

1. First, you must prepare the injection moulding machine, which also called injection machine.

2. Injection machine has two special pipes. After hydraulic extrusion, part A material and part B material, from different pipes, will join into another pipe (by this way, the part A and part B has been mixed evenly). You can add the appropriate color into the mixture. Then, you will get cured elastomers after heating operation.

 

Factors related to making silicone baby nipples:

1. Curing temperature

The higher temperature given, the higher curing rate.

2. Injecting pressure

In general, it can obtain good effect by using injection molding technology when the given temperature is in the range of 130-200 ℃, and the pressure in the range of 40-120 kg/cm2.

3.Curing time

The curing time of injection molding silicone rubber is within 10 seconds at150 ℃ when thickness of the target product is about 1 mm. Generally, the silicone baby nipples can be formed in a very short time.

4.Line shrinkage

When the temperature is within the range of 100-150 ℃, the line shrinkage rate of the baby nipples product is 2% to 3%.
