Detailed Manufacturing Process Flow

The production of high-performance hydraulic hoses, particularly those conforming to SAE standards, involves a meticulously controlled, multi-stage manufacturing process to ensure consistent quality and reliability. Each step is critical, from raw material selection to final testing.

1. Raw Material Preparation:

• Elastomer Compounding: High-grade synthetic rubbers (e.g., NBR, SBR) are mixed with specific additives, plasticizers, and curing agents to create compounds with desired properties like oil resistance, flexibility, and temperature stability. This is a critical stage influencing the inner tube and cover's performance.
• Steel Wire Procurement: High-tensile strength steel wire, typically brass-coated for better adhesion, is sourced from certified suppliers, meeting strict metallurgical specifications.

2. Inner Tube Extrusion:

The compounded inner tube rubber is fed into an extruder, where it is heated, plasticized, and forced through a die to form a seamless, precise internal diameter tube. This stage requires careful temperature and pressure control to achieve a uniform wall thickness and smooth bore, crucial for optimal fluid flow and long-term performance.

3. Reinforcement Application (Braiding):

The extruded inner tube is then guided to a braiding machine. A single layer of high-tensile steel wire is helically braided around the tube. The braiding angle (typically between 54° and 58°) and tension are precisely controlled by CNC machining to maximize pressure resistance and minimize elongation under stress. This forms the structural core of the hose, defining its pressure rating and burst strength.

4. Outer Cover Extrusion/Wrapping:

After reinforcement, the hose proceeds to the final layer application. For "smooth" covers, a pre-compounded, color-pigmented synthetic rubber is extruded directly onto the braided layer. For "wrapped" covers, the uncured rubber compound is typically applied as a sheet, followed by a fabric wrap during vulcanization to impart the distinct textured finish. The vibrant 'colourful' options are achieved through precise pigment dispersion in the rubber compound, ensuring consistent and fade-resistant hues. This cover provides protection against external factors and aids in system identification.

5. Vulcanization (Curing):

The uncured hose is then subjected to a controlled heating process (vulcanization). This chemical reaction transforms the rubber polymers into a durable, elastic, and thermoset material, imparting its final physical properties such as elasticity, strength, and resistance to heat and chemicals. This can be done in an autoclave or through continuous curing lines.

6. Testing and Quality Control:

Rigorous testing is performed at various stages and on the final product to ensure compliance with international standards like ISO 1436 and SAE J517. Key tests include:

• Impulse Testing: Simulates rapid pressure cycling to assess fatigue resistance and service life.
• Burst Pressure Testing: Measures the maximum pressure the hose can withstand before rupture.
