Silicone products in the production process which appears more common phenomenon, but for the product requirements of the technical phenomenon above the basic can be resolved on the ground, but the high-quality high-quality silicone products in the production process prone to black spots impurity phenomenon has become Many of the engineers and the transfer of the foreman of the distress, for the product dirty phenomenon is self-control problems, so individuals need to come up with the appropriate solution, but for personal requirements and ways to improve the way, you can mainly increase the appearance of adverse phenomena rectification , To deal with the product attached to the surface and the black spots inside the product appearance, so the production of high transparency silicone spoon production process which need to pay attention to some of the details!

silicone black spots


Raw materials lead to bad, black spots in the production process due to black spots in the raw materials which accounted for 20% of the total non-performing rate, so the need to carefully read the compound before the product to see if there is black dot impurity phenomenon. Followed by the second back to the material caused by excessive black spots, the general mixing compound long-term storage of vulcanizing agent failure after the need to add new curing agent vulcanizing agent, so in the second refining process from the hands and vulcanizing agent and the air which appears compound Pollution phenomenon led to the formation of vulcanized products have black spots of impurities, so the black spots for the control of raw materials need to pay attention to the requirements of the two sides of the operator Lianjiao, contact with the rubber tools, cutting the tool and the indoor environment of the environment clean!
 

Molding operations lead to: in the production process which the exhaust line of the machine is too likely to appear when the exhaust spots inhaled black spots impurities, so the environment around the machine and the indoor environment needs strict control, the mold has too much debris Also do not pay attention to the new on-line mold above the phenomenon of debris more, so the general silicone products manufacturers will first mold blasting or spray Teflon in the mold to keep mold clean can solve the key black spots in the The process of pound material need to pay attention to the hands clean, the work surface and all around the black spots may cause impurities in all the items clean up, human phenomenon is an important factor in the appearance of bad phenomenon, so because when their own finishing and rectification to develop good Operating habits, to prevent the appearance of black spots bad phenomenon!
