XJW-90 Model Rubber Extruder And Hot Air Vulcanization Box For
Rubber Water Hose Production
Production Process:
The following is the process flow of combining rubber hose extruder
with hot air vulcanization:
1. Raw material preparation
- Prepare suitable rubber raw materials and add various additives
such as vulcanizers, accelerators, fillers, etc. according to
product requirements.
2. Extrusion molding
- Put the mixed rubber raw materials into the barrel of the rubber
hose extruder.
- The screw in the extruder rotates, shears, squeezes and pushes
the rubber, so that it is extruded through the die head mold to
form an unvulcanized rubber hose.
3. Initial cooling
- The temperature of the newly extruded rubber hose is relatively
high, and it is moderately cooled through a preliminary cooling
device (such as a water cooling tank) to make it initially fixed.
4. Hot air vulcanization
- Send the rubber hose after preliminary cooling to the hot air
vulcanization equipment.
- The hot air blower in the vulcanization equipment generates
high-temperature hot air, so that the rubber hose undergoes
vulcanization reaction under certain temperature and time
conditions.
5. Secondary cooling
- After vulcanization, the rubber tube passes through a secondary
cooling device (such as air cooling or water cooling) to quickly
cool it to room temperature to fix the physical properties and
dimensions after vulcanization.
6. Pulling and winding/cutting
- Use a pulling device to pull the rubber tube at a uniform speed
to ensure its straightness and dimensional accuracy.
- According to the final requirements of the product, the rubber
tube is rolled into a roll or cut to a fixed length.
7. Quality inspection
- Perform an appearance inspection on the vulcanized rubber tube to
check for defects such as flaws, bubbles, deformation, etc.
- Perform physical property tests such as tensile strength,
hardness, aging resistance, etc. to ensure that the product meets
quality standards.
8. Packaging and storage
- Qualified rubber tubes are packaged to protect the product from
damage and contamination during transportation and storage.
- Store in a dry, well-ventilated warehouse, away from direct
sunlight and humid environment.
In the entire process, it is necessary to strictly control the
process parameters of each link, such as extrusion temperature,
extrusion speed, vulcanization temperature, vulcanization time,
cooling speed, etc., to ensure the quality and performance of the
rubber tube.

Advantages of hot air vulcanization include:
1. Uniform heating: Hot air can be more evenly distributed in the
vulcanization chamber, so that rubber products are heated evenly,
so as to ensure the consistency of vulcanization quality.
2. Wide range of application: It can be used for vulcanization of
rubber products of various shapes and sizes, and can also be better
treated for products of complex shapes.
3. The equipment is relatively simple: compared with some other
vulcanization processes, the structure and operation of hot air
vulcanization equipment is relatively simple and the cost is low.
4. Easy to control: By adjusting the temperature, wind speed and
time of the hot air, the vulcanization process can be controlled
more accurately.
5. Environmental protection: Usually does not produce a lot of
pollutants, relatively friendly to the environment.
