1. Whether the machine is normal, whether AB material and potassium dichloride are enough (not enough to feed first), start the machine to preheat and heat up, measure the flow rate, adjust the ratio of AB material, and check whether the temperature and air pressure are normal.
2. The temperature of the raw material is strictly controlled between 23-28 degrees, the temperature difference between the AB materials can not be greater than 5 degrees, and the pressure difference between the AB pipes cannot be too large, otherwise the flow ratio will be inaccurate.
3. The tip of the gun, whether the stirring is clean.
4. When the mold temperature is low, heat the mold first (the product with low mold temperature has no toughness, there are many bubbles, and the mold will stick to the mold seriously, and large pieces will fall off); in summer, if the mold temperature is too high, it should be cooled down (the temperature is too high, and the skin of the product is thin. , serious burns may occur).
5. The release agent needs to be sprayed in place, but it does not need to be too much. Too much spraying will cause wax skin on the mold, the surface of the product will be uneven, and the difficulty of cleaning the mold will increase. Too many cleaning times will shorten the service life.
6. The mold must be cleaned, the waste edges are blown clean, and then the release agent is sprayed. After the release agent is dry, the mold can be closed and injected.
7. The opening time of the mold should be well grasped, and it should not be too early. After taking it out, it will be matured for 48 hours before baking.
