Rubber products are treated after vulcanization:
After the vulcanization is completed, the rubber product often needs some post-treatment to become a qualified finished product. This includes:

  • The rubber mold product is trimmed to make the surface of the product smooth and the size meets the requirements;
  • After some special processing, such as the treatment of the surface of the product, the performance of the special-purpose products is improved;
  • Products containing fabric skeletons such as tapes, tires and the like are subjected to hot stretching cooling and vulcanization and then cooled under inflation pressure to ensure product size, shape stability and good performance.

1. Trimming of mold products after vulcanization
When the rubber mold product is vulcanized, the rubber material will continue to flow out along the parting surface of the mold to form an overflow rubber edge, also known as a flash or flash edge. The thickness and thickness of the rubber edge are determined by the structure and precision of the mold. The parallelism of the flat vulcanizer plate and the amount of glue remaining. Nowadays, the products produced by the infinite mold have a very thin rubber edge, and sometimes they can be removed or gently rubbed off when the mold is released. However, such molds are expensive and fragile, and most rubber moldings require finishing after curing.

  1. Manual finishing
  • Manual trimming is an ancient method of trimming, which involves manually punching the edges with a punch; using a knife such as scissors or a scraper to remove the edges. The quality and speed of hand-trimmed rubber products will vary from person to person. The geometry of the finished product must meet the requirements of the product drawings and must not be scratched, scratched or deformed. Before dressing, you must be clear about the trimming position and technical requirements, master the correct dressing method and use the tool correctly.
  1. Mechanical dressing
  • Mechanical punching and trimming The rubber edge of the product is removed by means of a press machine and a die and a punching knife. This method is suitable for articles and molded articles whose glue edges can be placed on the die or the punching plate, such as stoppers, cups, and the like. For products with high gel content and low hardness, the impact method is generally used to impact the trimming edge. In this way, the edge of the knife can be reduced due to the large elasticity of the product, and the side surface is concave; and the rubber content is lower and the hardness is higher. The product can be directly cut by the knife die method. In addition, die cutting is also divided into cold cutting and hot cutting. Cold cutting refers to punching at room temperature, requiring higher punching pressure and better punching quality. Hot cutting refers to higher temperature and die cutting. It should prevent the high temperature from contacting the product for too long and affect the product quality.
  • Mechanical cutting and trimming is suitable for the trimming of larger-sized products, using cutting tools. A side cutting machine is a special machine, and different products use different cutters. For example, after the tire is vulcanized, there are strips of different lengths on the surface of the gas eye and the vent line, and the strip must be removed using the grooved tool under the condition of the tire rotating.
  • Mechanical grinding and trimming For mold rubber products with inner and outer rings, grinding is usually used. The grinding blade is a grinding wheel with a certain thickness of the particles. The precision of grinding and trimming is low, and the grinding surface is rough, and there may be residual sand particles, which affects the use effect.
  • Low temperature shot blasting For fine products with high trimming quality requirements, such as 0-rings, small cups, etc., this method can be used for trimming. The product is rapidly cooled to below the brittle temperature with liquid nitrogen or dry ice, and then the metal bullet or plastic projectile is sprayed at a high speed to break the flash and peel off, and the trimming is completed.
  • Low-temperature brushing and trimming It removes the rubber edge of the frozen rubber product by means of two nylon brushes rotating around a horizontal axis.
  • Low temperature drum trimming It is the earliest adopting the method of freezing trimming. The impact force generated by the rotation of the drum and the friction between the products are used to break and fall off the edge of the product that has been frozen to below the embrittlement temperature. The shape of the drum is generally octagonal to increase the impact force of the product in the drum, the rotation speed of the drum should be moderate, and the addition of the abrasive can improve the efficiency. For example, the trimming process of the rubber plug of the electrolytic capacitor is to use a low temperature drum to trim.
  • Low-temperature vibration trimming, also known as vibration freezing trimming, the product is spirally vibrated in a ring-shaped sealed box, and there is a strong impact between the products and between the product and the abrasive, causing the frozen embrittlement drop. The low-temperature vibration trimming is better than the low-temperature drum trimming, the product damage rate is low, and the production efficiency is relatively low.
  • Low-temperature swinging and dither trimming are suitable for small or micro-products or micro-rubber products containing metal skeletons. Together with the abrasive, the edges of the product, the corners, and the edges of the grooves are removed.

Experts in the industry have pointed out that the future development of special rubber should aim at the defects of its own performance, promote technological performance through technological innovation, shorten the gap with international advanced technology, and adapt to the development of the automotive industry.
