Powder preheating
1.Powder preheating: weighing the raw material with proper box according to the needs of the weight tableware produced, and then putting it into the high frequency for uniform preheating.
Then put the preheated cake into the mold, start the plain surface program of the molding machine, and perform high-pressure and high-temperature curing molding.
Tip:
Powder cake box: Choose the raw material box according to the weight of the product. It does not need to be too large to hold the raw materials; the raw materials can generally weigh 2-4 grams more than the product, so that there will be no shortage of raw materials when you put a little burr;
Preheater machine : Put the weighed ingredients into the high frequency baking, do not press the high frequency too tightly, leaving a gap of 2-4 mm, which is conducive to the evaporation of gas and moisture; the raw materials should not heat too hard, the fine powder cake is no hard, no-loose, no-sticky with box.
Decal paper procedure
After cutting the flower paper coating with shinning powder, place it on the surface of the tableware after curing molding, and start the decal button of the melamine crockery molding machine; after the mold is automatically opened, sprinkle the glazing powder and press the button of glazing from the melamine crockery molding machine. After the mold is automatically opened again, you can take out the product. After high temperature curing and high pressure, the final product surface will be shinning and glossy.
TIP: After the initial pressure, exhaust, secondary pressure, the molding is completed, the plain surface molding / decal program / gold program, the procedure of each step is the same, but the data is different, and needs to be adjusted according to the actual needs, such as pressure, mold clamping time, Exhaust times of each step, etc.
Polishing procedure
After the melamine tableware is finished, there is burr wastage around the tableware, which is not conducive to consumer use. It needs to grind and polish to remove the burrs of the product to make the product look more beautiful and smoother.
TIP: After the product is sent to the polishing workshop, it is first coarsely ground by sanding paper, then finely ground by the impeller, and finally polished by the hemp and cloth wheels.
If you want the high production efficiency and high quality of the polishing quality, automatic trimming machine is the best way.Speed is 300-800pieces per hour.
Inspection and Packing
The last is inspection and packaging. After sanding and polishing, it is necessary to carry out initial inspection and re-inspection of the product. Pick out unqualified products, and good products can be put into the warehouse for packaging.
TIP: If you are a machine operator, your hands are covered with melamine powder and gloss powder. After work, you can use hand sanitizer to wash it off easily.
As can be seen from the above procedure, in the production process of melamine tableware, each item is very strict, and each process requires extremely precise work, which is why all melamine tableware is popular among the public.
