Quality Is More Important Than Anything Else

At Kinglin the quality inspection process and the equipment used are crucial to ensure that manufactured products such as silicone hoses meet the required standards and specifications. The following outlines the quality inspection process when producing silicone hoses:

1. Raw material incoming inspection

Process: This preliminary check ensures that raw materials such as silicone rubber and reinforcing fibers (such as polyester or aramid) meet predetermined quality standards.

It typically involves checking the chemical composition, and physical properties (such as hardness and tensile strength), and ensuring the absence of contaminants.

2. Process inspection

1. During the manufacturing process, the quality of the inner and outer glue is inspected, and there are multiple checkpoints to ensure that each step of the process meets predefined standards

2. Workers are in production: self-inspection by operators, mutual inspection by team leaders, and inspection by inspectors. If problems are found, 8D reports will be made to analyze, identify, and solve the problems.

2. Mixing and kneading: test the consistency and quality of the silicone rubber mixture, and monitor parameters such as film layer thickness

3. Extrusion and molding: When forming the hose, perform dimensional inspections (such as inner diameter, and wall thickness) to ensure compliance with requirements

4. Vulcanization process: The inspector checks the vulcanization time and temperature every day to ensure the best physical properties of the hose. After vulcanization, the hose is visually inspected to see if it meets the specifications. If it is found to be unqualified, it will be stopped as soon as possible and the cause will be investigated to implement rectification measures.

5. Cleaning inspection: After cleaning the silicone hose, the quality inspector will check the surface of the hose one by one for defects, irregularities, and consistency.

3. Visual inspection

After the silicone hose is completed, 3D tooling inspection and dimensional inspection will be carried out to ensure that all hose dimensions meet customer-specific requirements.

4. Laboratory testing

We are equipped with advanced equipment to test the performance and quality of our products from multiple dimensions. This comprehensive laboratory testing is conducted by skilled professionals to confirm that silicone tube products meet specifications. Testing may include measuring tensile strength, breakage Elongation, and wear resistance, burst pressure, anti-aging and weathering, etc.

5. Finished product

After the cost production and inspection are completed, we will send the sample to the customer for review.

After the customer confirms that it is correct, mass production will begin.

6.random sampling

Each batch of products will undergo sample testing before leaving the factory to ensure that it meets quality standards. This typically includes statistical process control to identify any variation within a batch and ensure consistency.

Before packaging, the hoses undergo a final inspection to ensure that no defects have appeared during handling

Silicone Hose Production Process

1. Material Preparation:

The production begins with high-quality silicone rubber, usually a high-temperature vulcanization type, mixed with color pigments and necessary additives to optimize its properties.

2. Layer Construction:

Silicone is combined with reinforcing materials such as polyester or aramid cloth, forming multiple layers that enhance the hose’s strength and temperature resistance.

3. Hose Formation:

Depending on the required shape and complexity, silicone hoses are formed through:

1. Hand-Wound: Manual wrapping of silicone and cloth layers around a mandrel, followed by vulcanization.

2. Extrusion: Pushing the silicone mixture through a die to shape the hose into continuous lengths.

3. Molding: Silicone is placed in molds and shaped under heat and pressure for more intricate designs.

4. Vulcanization:

The hoses are cured in a vulcanizing oven where high temperatures set the silicone, enhancing its mechanical and thermal properties.

5. Demoulding and Cooling:

Post-vulcanization, the hoses are removed from their molds or mandrels and allowed to cool.

Cleaning: The hoses are thoroughly cleaned to remove any residues or particulates from the production process, ensuring a clean finish.

Cutting to Specifications: The hoses are cut to predetermined lengths as per customer or market requirements.

6. Quality Inspection:

Each hose undergoes rigorous inspection for dimensional accuracy, burst pressure, and other quality parameters to ensure compliance with standards.
A free production sample is sent to the customer for review and approval. This allows the customer to assess the quality and suitability of the hose in their specific application.

7. Packaging and Dispatch:

Finally, the hoses are packaged, possibly with customer-specific branding, and prepared for shipment to wholesalers.

Choosing Silicone Hoses: Temperature & Pressure Guide？

When selecting silicone hoses, especially for specific applications like automotive, heavy machinery, or industrial environments, the choice of reinforcement materials—typically cloth layers within the hose—is crucial. These materials can vary primarily based on their resistance to temperature and pressure. Here’s how they differ:

Pressure Resistance

The pressure resistance of a silicone hose largely depends on the type of reinforcement used and the construction of the hose (number of layers).

1. Cloth Layers: The number of cloth layers within a hose impacts its ability to withstand internal pressures. More layers generally mean higher pressure resistance. This is important in applications where hoses are subject to high dynamic pressures, such as turbochargers or high-pressure fluid transport.

2. Type of Cloth: The material of the cloth also affects pressure resistance. For instance, aramid cloths provide not only higher temperature resistance but also superior strength, which translates into better pressure handling capabilities compared to polyester.

3. Steel wire reinforcement layer
The addition of a wire reinforcement layer significantly enhances the stability of its structural integrity and enables it to withstand higher pressures

Temperature Resistance

Different cloth layers provide varying levels of temperature resistance, which is critical depending on the application’s thermal demands.

1. Polyester Cloth: This is commonly used in standard silicone hoses suitable for moderate temperature applications. Polyester-reinforced silicone hoses can generally withstand temperatures from -40°C to +180°C. This makes them suitable for general automotive and industrial applications where extreme temperatures are not a factor.

2. Aramid (Nomex) Cloth: Aramid fiber is known for its excellent heat resistance and strength. Aramid-reinforced silicone hoses can tolerate much higher temperatures, from -40°C to +250°C. This range makes them ideal for performance automotive applications, such as in racing or high-performance engines, where higher temperatures are common.

Reinforcement Material	Temperature Resistance	Pressure Rating(Working)	Applications
Polyester	Up to +150°C	0.5-1.5 bar	Cooling systems, HVAC
Aramid Fiber	Up to +250°C	1.5-3.0 bar	High-performance automotive systems
Steel Wire	Up to +200°C	Above 4.0 bar	Hydraulic systems
Fiberglass	Up to +260°C	1.5-3.0 bar	Turbo hoses, exhaust systems

Chapter5

The service life of the silicone hose?

The service life of silicone hoses is notably longer than that of many other hose materials, primarily due to silicone’s superior resistance to factors that typically degrade hoses. Here are some key aspects that contribute to the longevity of silicone hoses:
Temperature Resistance:
Chemical Resistance:
Flexibility and Elasticity:
Resistance to Moisture and Corrosion:

Due to these properties, silicone hoses are generally considered to have a “nearly indefinite” shelf life if stored properly and can last for many years under typical operating conditions. In practical automotive and industrial applications, the actual service life can vary but is often significantly longer than that of conventional rubber hoses, sometimes lasting as long as the equipment or vehicle itself with proper installation and maintenance.

Chapter6

What silicone hose is oil resistant?

Silicone hose, by itself, is not typically oil-resistant and is therefore not recommended for use with oil without proper modifications. However, for applications requiring oil resistance, fluorosilicone can be used. Fluorosilicone retains the properties of standard silicone but is designed to also be resistant to oil and other chemicals. This makes it an excellent choice for applications involving oil or fuels.

If you are considering a silicone hose for use with oil, I would recommend opting for fluorosilicone hoses. These hoses offer the benefits of regular silicone, such as flexibility, high-temperature resistance, and longevity, but with the added advantage of being resistant to oils and chemicals. This makes them suitable for more demanding applications where exposure to such substances is a factor.

Chapter7

Silicone Hose Production Process

The production of silicone hoses can be achieved through several distinct processes, each tailored to produce specific types of hoses with unique characteristics suitable for different applications.

1. Hand-Wrapped Silicone Hose Production:

Manual Construction: Layers of silicone and reinforcing materials (like fabric or wire mesh) are manually wrapped around a mandrel. Features: These hoses typically have a very smooth interior and exterior surface and can be tailored to a wide variety of configurations and dimensions.

2. Extrusion of Silicone Hose:

Continuous Production: Silicone material is forced through a shaped die using an extruder, creating long, continuous lengths of hose. Features: Generally has uniform wall thickness and is less flexible than hand-wrapped or molded hoses

3. Molded Silicone Hose Production:

Mold Use: Silicone rubber is placed into a pre-shaped mold and cured under heat and pressure. Complex Shapes: Suitable for creating hoses with intricate shapes, such as sharp bends, T-shapes, or reducer hoses.
