Horizontal Silicone Rubber Vulcanization Line

In recent years, silicone rubber material have been evaluated for their properties such as odorlessness, heat resistance, cold resistance, and flexibility, which are unlikely to cause chemical reactions with other substances other than those used for conventional industrial products. It is used in products in various fields such as electronic components, food, and medical.

Mitsuba Mfg Co. Ltd. has a silicone rubber vulcanization line that can continuously produce tubes and profile products used in these fields from extrusion to vulcanization according to the size and shape of the product.

We have two types of manufacturing equipment: a horizontal silicone rubber vulcanization line (horizontal extrusion) and vertical silicone rubber vulcanization line (upward extrusion).

This page introduces the horizontal silicone rubber vulcanization line.

        Horizontal silicone rubber vulcanization line

【Features】

①It is possible to produce with the line speed increased.(Note: Depends on vulcanization conditions and installation space)

②Since the height of the equipment is low, if it is the height of a general factory, it can be installed without renovation of the

    building.

③Since you can work on the floor, maintenance and work can be done easily.

【Suitable product】

①Tubes and hoses with light product weight.

②Tape-shaped or mouth-shaped profile products with few uneven凹凸surfaces (especially the lower surface side).

1.Silicone Rubber Extruder

①With a rich Line-up of screw sizes from 20㎜~120㎜,you can choose

    according to your production conditions.

    Vent type is also available for each size of 30 mm or more.

②Multi-layer extrusion such as two-layer or three-layer is also available.

③If the silica content is high, various wear-resistant materials can be

    selected for the screws and cylinders.

④We have taken measures against coloring by metal touch.

⑤For silicone rubber, which has a fast cross-linking reaction, we also

    have a screw shape for low-temperature extrusion that suppresses

    shear heat generation in the cylinder.

2.Material Supply Equipment

Immediately before extrusion, the customer can automatically supply the ribbon with the optimum width to the extruder simply by putting the vulcanizing material in an open roll or pressure kneader and putting it in as a B-kneaded mass.

By hand, the material can be cut into strips, and workers do not have to stand to the slot, which leads to labor saving.





3.Pre-Vulcanization Furnace

By installing a pre-vulcanization furnace at the inlet of the vulcanizer and hardening the surface of the work, it is effective in preventing belt marks and maintaining the shape in the vulcanizer.






4.Horizontal vulcanizer

①We propose a method suitable for vulcanization conditions from two

    types, a far-infrared heater type and a HAV method that uses a hot air

    generator.

    [Far red heater type]

    Since the atmosphere temperature inside the furnace can be set to a

    high temperature of 500 ℃, the vulcanization reaction is promoted,

    leading to an increase in line speed.

    [HAV method]

    Although the temperature inside the furnace is as low as 230 ℃ or

    less, air can be used as a heat medium to uniformly heat the work

    surface, making it suitable for sponge products that require cell

    uniformity.

②Belt transport type

    Small products and hollow products with low take-back tension are transported on an endless belt

    installed in the vulcanization furnace.

    The endless belt has been devised so that it can be easily replaced.

③Safety measures

    As a fire countermeasure, a nitrogen gas generator (option) can be installed in the furnace.

5.Ancillary equipment

We have prepared ancillary equipment to meet various requirements, such as a winding machine for drums for long products and a cutting machine for cutting short products to a fixed size, according to the next process and shipping form of the vulcanized product.

Double winder

Each size is available according to the drum used.

Hall-off Cutting Machine

It automatically halls off, disconnects, and takes out.
There is little error in length and the cross section can be cut smoothly.




6.Control and Operation

For control and operation, we design and manufacture both hardware and software in-house according to the movement of each device from the mechanical design stage so as to meet the customer's usage and requirements.

We are also working on IoT, including automation and safety measures, so please tell us your company requirement.
