Many people have the question: how can the quality of the product be distinguished? How can we see the quality of the product? And what is the definition of defective products for silicone products? Each industry and each brand products, because the quality is so different requirements will be different, such as some well-known brands, the import and export of products, the appearance of jewelry parts and so on are more stringent, on the quality of the product definition is different, so in the molding of silicone products which meet the bad?

Silicone products in the forming of common problems, the most serious is the products are not ripe, Bao Feng, edge dismantling, lack of material and other bad conditions. These are the operators in the production process often encountered problems, and no silicone products can also be divided into several parts, local unfamiliar, unfamiliar, all unfamiliar, these harmful can be improved through the production process, and control the production of machine parameters (time, temperature, pressure, etc.) can effectively solve the problem.

In addition, the low hardness silicone products are easier to disperse and bubble. Low hardness silicone products refer to silicone products below 20 degrees of hardness. Such products are prone to disperse and bubble problems, which make the production process very headache. How to solve them? Magnesium Oxide is very easy to mix, but difficult to disperse, should be added; magnesium carbonate, titanium dioxide and rubber compatibility is poor and difficult to disperse, not oil added; N330 should not be difficult to disperse, and adding oil; clay, talcum powder, N550/N774/N990 can be added to and mixed with oil; adding ingredients to disperse no, a knife, and slowly enlarged saw, to maintain a certain accumulation of gum; completely when eaten, and then cutting knife; cool enough, can be considered before curing agent oil is added; (especially the hardness below 30 degrees, need a lot of filling oil; gas before the proposal thin mix parked several times; after adding curing agent, also has a good effect. (the above is for reference only, inadequacies, please point out that we learn with heart and improve it.)

No local silicone products in the production process have occurred, the main reason is generally the production machine parameters, not to control the curing time and curing temperature causes unfamiliar, in doing the product first time, due to the operation of personnel, to set up a short curing time, the mold temperature is too low, it will appear some unfamiliar, adjusting the mold temperature and curing time can change this situation.
