The extrusion process of the silicone strip extruder is also a very complex process. We take the silicone extruder to produce tires as an example. At a certain low temperature, in the process of manufacturing tires, the extrusion molding method used dissolves the silica gel, and then extrudes it through the die of the head to form the shape required by the process. This is a difficult process, not only requires the correct inspection of the silicone extruder before operation, but also requires the operator to have rich experience. The combination of technology and experience is needed to complete this process well. Then, let's learn about the introduction and application of the extrusion molding process of the silicone strip extruder!

The method of extrusion molding of silicone rubber strip extruder has relatively high technical requirements, but this method is more efficient and can reduce the production cost of enterprises, which is worthy of wide application of industry enterprises. During the production process of the extruder, it must be noted that the extruder needs to apply a certain pressure to the feed port to ensure the stability of product production. Therefore, it is necessary to adopt the corresponding method to control the temperature. Mold temperature cooling is a good way to cool down. Another point is that the molded rubber is softer because it has not been vulcanized. This time it is necessary to vulcanize in a vulcanizing furnace.

After the silicone products are extruded by the extruder, they are suspended in the air through the pre-high temperature vulcanization tunnel to achieve pre-vulcanization and rapid shaping; then they are fully vulcanized through the post-drying channel, which solves the production problems that cannot be solved by the traditional silicone rubber extrusion vulcanization process. Quality problems; Extruded vulcanized thin-walled tubes are very round without any deformation; Extruded vulcanized large-diameter silicone tubes and thick-walled tubes with no indentation on the surface; Extruded vulcanized special-shaped silicone strips with complex cross-sectional shapes; Ensure that the size and shape are very beautiful, and can ensure excellent extrusion vulcanization effect for various soft and hard silicone rubber with hardness of 30 to 70 degrees. The inner and outer layers of the drying tunnel are made of the drying tunnel are made of stainless steel. Excellent thermal insulation performance, no pollution to the product; Special Shi Ying heating tube is adopted for interactive utilization of high temperature and radiation, with short vulcanization time and high thermal efficiency. After the drying tunnel reaches the set temperature, it will automatically switch to constant temperature control and then automatically shut down, saving electricity. It can be used to produce silicone tube, silicone strip, special-shaped strip, foam tube, etc. The production vulcanization time is short, the production efficiency is high, and the output per hour is about 60-180KG. The operation is very convenient.

Application of Silicone Strip Extruder

1. Silicone strip extruder is widely used in silicone tube, various sealing strips, sealing rings, automobile tires, silicone tube composite tube extrusion, silicone tube multi-layer co-extrusion. Composite extrusion production process is an advanced technology in rubber industry. According to the different performance requirements of the product, choose different formulations and properties of rubber materials. Through the composite extrusion equipment, materials can be saved and various performance requirements can be met. the requested product.

2. Silicone strip extruder is also used in housing construction, wire and cable, automobile industry and other fields. In terms of housing construction, it is mainly used for roofing single-layer waterproofing materials; in terms of wires and cables, it is mainly used for input lines of civil and commercial buildings, construction wires, mining cables, nuclear power plant wires, automobile ignition wires, control and Signal cables are mainly used for non-tire parts of tires, trucks and buses in the automotive industry, including water tank and heating hose, sealing strip, rubber belt, body and chassis parts, rain strip, floor and ring pipe. Wait. 3. Silicone extruder is used in LED field, such as LED soft light bar, soft light bar, LED sleeve, neon light, optical light bar, etc.

4. Silicone strip extruder is used in the medical field, such as urinary catheter, drainage tube, silicone peristaltic pump tube, tracheal intubation, medical feeding tube, central venous catheter, etc.

5. Silicone strip extruder is also widely used in the field of baby products, such as bottle straw, medical sterile bottle, silicone baby gum, milk tea nipple, silicone children's toys, etc.
