Rubber Vulcanizing & Pressing Functions:

1. Temperature, time and pressure are the three major process parameters of vulcanization of rubber products. The vulcanization temperature is the most influential parameter on the performance of rubber products, but the vulcanization pressure of rubber is also not negligible, then the small series of Huacheng Hydraulics will introduce to you. :
2. Rubber vulcanization refers to the pressure per unit area during the vulcanization process of rubber compound rubber. At the same time, it is also an important factor to ensure the geometrical dimensions, structural density and physical and mechanical properties of rubber parts, and to ensure the smooth surface of the parts. Defects have an important role in achieving the sealing and airtight requirements of the product.
3. In the selection of rubber vulcanization pressure, it is necessary to consider the formulation of the rubber compound; the plasticity of the rubber compound; the structural form of the molding die (molding, injection, injection, etc.); the type of vulcanization equipment (flat vulcanizing machine, injection vulcanizing machine, injection) Vulcanizing machine, vacuum vulcanizing machine, etc.; the structural characteristics of the product are these five factors.
4. In addition to the above effects, the rubber vulcanization pressure is extremely important in improving the compactness, torsion resistance and physical and mechanical properties of the rubber product. The rubber vulcanization pressure can also provide power for the filling flow of the rubber compound, so that the rubber compound is in the It can fill the entire cavity within the specified time and has a great effect.
5. However, it should be noted that the vulcanization pressure of the rubber should be kept appropriate. If it is too large or too small, it will have some adverse effects. Qingdao Xinyefei Machinery Co., Ltd. stated that the rubber vulcanization pressure is too large to damage the molds, equipment and power consumption, and it is important to affect the performance of the products. Too small a pressure will have a direct impact on the geometry and physical and mechanical properties of the product, so the rubber vulcanization pressure should be kept appropriate.

Plates Heating Brief Introduction:

• At present, most of the heating still uses steam. Steam is used as a heat source for different pressure levels in various processes of vulcanization, and is the main medium for rubber vulcanizer/heating. Providing sufficient heat in the vulcanization process in a timely and accurate manner is a necessary condition for ensuring the quality of vulcanization. Let us introduce the benefits of low pressure use of the vulcanizer steam line. After the high pressure steam is depressurized, part of the condensed water evaporates, the dryness of the steam increases, and the steam quality increases. The latent heat of steam at low pressure is greater and the heat transfer effect is better. The heat of the condensed water produced by the steam after the low-pressure use is reduced, and the energy waste after the discharge is small. Low pressure steam is safer. The pressure can be used to control the temperature by depressurization. At present, most tire companies choose “low pressure use” for low pressure steam supply selection, but low pressure use requires high piping design and construction. At the same time, because the vulcanizer is also shaped with low pressure steam, low pressure steam directly enters the capsule, so the steam quality The requirements are high, and there are mainly the following problems in low-voltage use. The steam regulating valve is unstable in operation and has a low service life. The steam pressure is unstable, which is likely to cause batch temperature drop and pressure drop. The steam condensate is not discharged in time, and the temperature of the hot plate fluctuates greatly.
