100 Ton Sealing Gasket Vacuum Compression Molding Machine / Rubber Processing Machinery

100 Ton High Efficiency Easy Operation Sealing Gasket Vacuum Compression Moulding Machine

Vacuum forming is a thermoplastic plastic plate, sheet is fixed on the mould, with radiation heater heated to softening temperature, and then the die with the plate by using a vacuum pump (sheet material) between the air pump to make the plate (sheet material) parison according to mould contour forming, cooling stereotypes after products use compressed air to blow out of the mould and demoulding.

Choose the right molding machine according to different plastic products. A good molding products, can achieve the effect of half work half. Improving the quality of products also improves the production efficiency, and recently improves the production capacity, that is to say, can create more profits for the enterprise. Therefore, the choice of a good plastic molding machine equipment is crucial.

What are the main factors affecting the vulcanization process:

1. Vulcanization temperature: If the temperature is 10 °C higher, the vulcanization time of the vulcanizing press is shortened by about half. Since the rubber is a poor thermal conductor, the vulcanization process of the product differs due to the difference in temperature of each part. In order to ensure a relatively uniform degree of vulcanization, thick rubber products generally adopt a gradual heating, low temperature and long-term vulcanization.

2, vulcanization time: This is an important part of the vulcanization process. The time is too short, the degree of vulcanization is insufficient (also known as sulfur). The time is too long, the degree of vulcanization is too high (commonly known as sulfur). The vulcanizing machine only has a suitable degree of vulcanization (Commonly known as vulcanization), to ensure the best overall performance.

Sulfur dosage: The larger the dosage, the faster the vulcanization rate, the higher the degree of vulcanization that can be achieved by the vulcanizing press. The solubility of sulfur in rubber is limited, and the excessive sulfur will be precipitated from the surface of the rubber compound. Sulfur". In order to reduce the phenomenon of sulfur spraying, it is required to add sulfur at the lowest possible temperature, or at least below the melting point of sulfur. According to the requirements of rubber products, the amount of sulfur in soft rubber is generally not more than 3 %, the amount in the semi-hard rubber is generally about 20%, and the amount in the hard rubber vulcanization condition can be as high as 40% or more.
