The production process of woven silicone tubing is a complex and delicate process that combines technologies from multiple fields such as materials science, mold design, and mechanical automation. The following is a detailed analysis of the production process:

1、 Raw material preparation

The main raw materials for weaving silicone hoses include silicone rubber, fillers, additives, and vulcanizing agents. Silicone rubber is the main material of silicone hoses, providing the basic elasticity and heat resistance of silicone hoses. Fillers are used to increase the hardness and strength of silicone tubing, while additives are used to improve its processing performance and heat resistance. Vulcanizing agents are key substances that maintain the stability of silicone at high temperatures.

In the raw material preparation stage, it is necessary to accurately weigh and mix these components to ensure the quality of the silicone tube. The mixing process requires attention to controlling the mixing time and temperature to ensure the quality and stability of the silicone material. The mixture needs to form a paste with good fluidity in order to smoothly shape during the subsequent extrusion process.

2、 Rubber mixing and compounding

Rubber mixing is the process of mixing silicone rubber, fillers, additives, and vulcanizing agents in a double stick rubber mixing machine. At this stage, an appropriate amount of vulcanizing agent (such as platinum vulcanizing agent, BOP vulcanizing agent, or bis (tetra) vulcanizing agent) and silicone masterbatch need to be added to obtain the desired color and vulcanization performance. Through the shearing and extrusion action of the rubber mixing machine, the raw materials are uniformly mixed together to form a uniformly thick silicone extrusion material.

3、 Extrusion molding

Extrusion molding is one of the key steps in the production of woven silicone tubing. Install the mold on the head of the silicone extruder and cut the refined rubber material into shapes of consistent size and length for feeding from the inlet of the extruder. By controlling the pressure and temperature of the extruder, the silicone material is extruded into soft silicone hoses.

The design of the extrusion mold determines the shape and size of the silicone tube. The selection and preparation of molds need to consider factors such as the size, shape, and wall thickness of silicone tubes. The process of mold preparation includes steps such as drawing design, mold opening, processing, mold testing, and mold repair. During the extrusion process, it is necessary to strictly control the extrusion speed and pressure to ensure the accuracy of the size and shape of the silicone tube.

4、 Weaving and reinforcement

For silicone tubing that requires weaving, the extruded hose needs to undergo weaving reinforcement treatment. The weaving layer is usually made of high-strength fibers such as polyester fibers, nylon fibers, or stainless steel wires, which can provide additional strength and wear resistance. The weaving process requires the use of a specialized weaving machine to evenly wrap the fibers around the silicone hose, forming a tight woven layer.

The density and thickness of the weaving layer can be adjusted according to customer needs. Generally speaking, the higher the weaving density, the better the strength and wear resistance of silicone tubing. Meanwhile, the weaving layer can also add different colors or patterns as needed to enhance the visual effect and aesthetics of the silicone tube.

5、 Sulfurization treatment

The vulcanization process causes cross-linking reactions between the molecular chains of silicone rubber, forming a stable three-dimensional network structure, thereby improving the elasticity and heat resistance of silicone rubber tubes. Sulfurization can be carried out immediately after extrusion molding, or the woven silicone tube can be placed in an oven for secondary vulcanization.

The vulcanization temperature and time need to be adjusted according to the formula and thickness of the silicone tube. Generally speaking, the vulcanization temperature of ordinary silicone is around 180 degrees, while the vulcanization temperature of gas-phase silicone is slightly higher, about 200 degrees. The vulcanization time is usually around 2 hours. Through vulcanization treatment, the odor on silicone hoses can be removed, frost and yellowing can be prevented, and the hardness and strength of silicone hoses can be improved.

6、 Inspection and Quality Control

After the production of woven silicone tubing is completed, strict inspection and quality control are required, including appearance inspection, wall thickness measurement, quality inspection, and performance testing. The appearance inspection mainly checks whether there are cracks, bubbles, impurities and other defects on the surface of the silicone tube; The wall thickness measurement uses professional measuring tools to accurately measure the wall thickness of the silicone tube; Quality inspection is carried out by weighing and other methods to check whether the quality of the silicone tube meets the requirements; Performance testing includes testing of indicators such as tensile strength, tear strength, and heat resistance.

Only after passing the inspection and certification of the quality inspection department can woven silicone hoses be sold from the factory. Quality control is an important guarantee for ensuring the stable and reliable quality of silicone tubing, which runs through the entire manufacturing process.

7、 Subsequent processing and packaging

According to the customer's requirements, woven silicone tubing still needs further processing and packaging. Subsequent processing includes steps such as cutting, bonding, and punching. Cutting is the process of cutting silicone tubing to the length required by the customer; Adhesive bonding is the process of bonding the two ends of a silicone tube or other components to form the desired shape and function; Punching is to drill holes on the silicone tube for the installation of other accessories or connection.

The packaging material needs to have good moisture, dust, and scratch resistance to ensure that the silicone tube is not damaged during transportation and storage. At the same time, the packaging also needs to indicate the product's name, specifications, quantity, production date, and other information for customers to identify and use.

The production process of woven silicone tubing is a complex and delicate process that involves multiple fields of technology and techniques. Through strict raw material preparation, rubber mixing and blending, extrusion molding, weaving and reinforcement, vulcanization treatment, inspection and quality control, as well as subsequent processing and packaging, high-quality woven silicone tubes can be produced.
