What is a vacuum flat vulcanizing machine

   The vacuum flat silicone 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. There are single-base and double-base forms, and there are safety enclosures and mold clamping mechanisms. Users can choose to use them according to process requirements.

Features of vacuum flat vulcanizing machine:

1. Compared with the existing commonly used models, this machine has the following characteristics: the lower hot plate can be raised and lowered; the upper hot plate can be replaced with different thickness vulcanization molds, and the upper hot plate is located in the vacuum box, and the temperature of the hot plate is uniform.

2. High thermal efficiency. The vacuum sealing strip is placed on the closed surface of the vacuum box to realize the tight closure of the vacuum box and the lower splint, and the seal is reliable.

3. It is not easy to be damaged and easy to replace. The vulcanization mold is fixed on the splint, which can automatically open the mold to improve the operating environment and reduce labor intensity; it is controlled by a programmable controller, with a high degree of automation, stable and reliable control, simple and convenient installation and commissioning, and deflation The number of times and curing time can be set arbitrarily.

Vacuum flat silicone vulcanizing machine working principle:

1. The main machine of the flat vulcanizing machine adopts a four-column structure, and the pressurization form is a downward pressure type. 4 columns connect the upper beam and machine base to form a stable frame, the vacuum cover is fixed on the upper beam, the upper hot plate is fixed in the vacuum cover, and the machine base is installed - a main hydraulic cylinder and two auxiliary hydraulic cylinders , Two auxiliary hydraulic cylinders are installed on the upper beam.

2. The hydraulic cylinders are all single-acting hydraulic cylinders. The symmetrical arrangement of hydraulic cylinders on both sides not only meets the aesthetic requirements, but also makes the machine run more smoothly, reduces hydraulic oil leakage and improves the quality of molded products.

3. The plunger of the main hydraulic cylinder is connected with the lower hot plate, and the piston rod of the auxiliary hydraulic cylinder is rigidly connected with the movable platform. Driven by the auxiliary hydraulic cylinder, the lifting of the lower mold splint can realize the opening and closing of the lower mold splint and the vacuum cover. Driven by the main hydraulic cylinder, the hot plate can be raised and lowered in the closed vacuum cover to meet the requirements of different thickness molds and deflation and pressurization. The joint between the lower heating plate and the vacuum cover adopts standard vacuum seal, and there are T-shaped slots on the upper and lower heating plates for clamping the mold.

Vacuum flat silicone vulcanizing machine application:

   The flat silicone vulcanizing machine is suitable for button products such as mobile phone cases, O-rings, silicone bracelets, silicone remote controls, household appliances accessories, and food utensils. Silicone handicrafts, toy accessories, automotive silicone parts, industrial silicone parts, sports equipment, various kitchen utensils, multi-layer molded products and other complex silicone and rubber production and processing, etc.
