There are two types of vulcanizing machine: vacuum vulcanizing machine and flat vulcanizing machine. What is the difference between these two types of vulcanizing machine? Which type should you choose when choosing? Today we will mainly talk about the difference between these two models, so that everyone can distinguish them.
First of all, let’s tell you what is vulcanization. The vulcanization process is to cross-link the silica gel molecules to form a network structure, thus improving the use characteristics of silica gel. This change is called “vulcanization”. Natural rubber was originally vulcanized with sulfur, from which the term “vulcanization” comes from. According to different vulcanization methods, it can be divided into hot vulcanization, cold vulcanization, high frequency vulcanization and so on.
Thermal vulcanization is the heating and vulcanization of silica gel with electricity or steam, which is used to vulcanize various mold products and various silicone rubber products.
Vacuum vulcanizing machine, automatic mold opening integrates the functions of pre-compression, automatic deflation, pressure-holding vulcanization, and automatic mold release required by various rubber vulcanization processes. It is easy to understand that the vulcanization process is completed in a vacuum environment vacuum hood, which can improve product quality, reduce defective rate, and can save or reduce the intensity of deflation action at the beginning of vulcanization. According to the temperature rise, carry out segmental pressurization and pressurization and constant temperature, work in a vacuum state to remove excess gas and moisture, and use PLC programmable controller, all mold parameters can be stored in the touch screen, real-time curve records working temperature, pressure, time process Elements, Chinese + English display control is more convenient, accurate and reliable, and the infrared light curtain protects the safe operation, and can also be mass produced.
The flat vulcanizing machine is mainly used for vulcanizing flat tapes. Then I will talk about the structure of the flat vulcanizing machine. It has the advantages of high pressure per unit area of the hot plate, reliable operation of the equipment and less maintenance. The main function is to provide the pressure and temperature required for vulcanization. The pressure is generated by the hydraulic system through the hydraulic cylinder, and the temperature is provided by the heating medium. The plate vulcanization motorized template rises quickly at low pressure, locks at high pressure, automatically opens the mold after a delay, and automatically exhausts to improve production efficiency; when the product is hot-pressed, the oil pump motor stops working to reduce noise and save power, and has an automatic pressure supplement function, equipped with multiple sections The pressure program and pressurization speed are controlled to meet the process requirements, and the proportional oil circuit configuration is more reasonable and reliable; the deflation time, deflation times, heating temperature, hot pressing, cooling and vacuum time can be set freely. Heating control, no contact, long life, high precision.

The vacuum vulcanizing machine is suitable for the vacuum vulcanization molding process of silicone products, especially for the production of various forms of seals. The product is molded and vulcanized in a vacuum negative pressure environment, which is easier to exhaust and less likely to form air bubbles. Users can choose to use it according to the process requirements.
the
The above introduction to the vacuum vulcanizing machine and the flat vulcanizing machine, after seeing the difference in configuration and function, when choosing, the vacuum vulcanizing machine is aimed at specific users and specific products. Generally, I buy it and classify it as a customized type of flat vulcanizing machine. Machine, when choosing, if the vulcanization of the product needs to be completed in a vacuum environment, choose a vacuum flat vulcanizer. On the contrary, if the more conventional products do not need to be vulcanized in a vacuum environment, you can choose a flat vulcanizer.
