Stoma

In the production of resin handicrafts, for products with very complex structures and too small products, in the corners where the air resistance is large, such as corners, the air holes are most likely to appear, and some air holes even expose the surface of the resin products, to solve these problems, some resins Handicraft manufacturers use the following methods:
1.  in the complex and sophisticated mold design process to take into account the problem of stomatal, to design type, in the corner to add air vents, which facilitates the pumping effect, reduce the probability of occurrence of stomata.
2.  as little as possible with some white and red raw materials, so that the resin crafts solidification time increase a little, in order to save enough time to extract the air in the mold.
3.  look at the vacuum extractor has no mechanical failure, to ensure that the resin crafts in the vacuum chamber of the pumping speed is quickly reached 0.2Mpa, so that the vacuum treatment will be very good, and there are some resin handicraft manufacturers of large resin crafts The product is to take a vacuum of 0.2Mpa and then reduced to 0.08Mpa, and then back to 0.1Mpa, this kind of pumping effect is also very good.
4.  Use some dilute resin materials or less filler to make thinner dilute material, so that when the air is drawn, the air in the mould can be extracted cleanly and no air bubbles will appear on the surface of the product.
