Does the size of the silicone tube make it more difficult to open the mold? In life, small specifications of silicone tube can be seen everywhere, some large size such as the inner diameter of 40 or 50 mm, or even greater than 100mm silicone tube market demand, some people will ask such a large specification in the production can control the size? Does the product meet the requirements? First of all, the extrusion silicone tube in feeding, after the mold, high temperature baking to the final molding out, during the change of temperature and time, the size of the pipe will be different, which requires the operator to control the tolerance range at any time. The normal diameter is below 5mm, the standard of the line is allowed in the range of plus or minus 0.1mm, if the inside and outside diameter is between 5-10mm, there will be a standard of plus or minus 0.15mm. The larger the size of the silicone tube does not mean that the mold cannot be opened, but the tolerance will increase with the increase of the size.
