The manufacturing process of riot control equipment, depending on the type of equipment, covers the entire process from selecting high-performance materials to precision molding, composite processing, and rigorous testing. The core focus is ensuring its reliability under extreme conditions.
Material Selection and Pretreatment The performance foundation of riot control equipment is materials science. Key materials include:
Metallic Substrates: High-strength alloy steel (such as Q690D) is used for explosion-proof containers; lightweight aluminum alloys (such as 6061-T6) are used for riot shields, balancing strength and portability.
Non-metallic Composite Materials: Aramid fibers (Kevlar®), ultra-high molecular weight polyethylene (UHMWPE), and ceramic composite materials (such as boron carbide) are widely used in bulletproof layers, possessing high tensile strength and impact resistance.
Auxiliary Materials: Epoxy structural adhesives, fluororubber sealing rings, etc., are used to enhance adhesion and sealing performance.
Materials require pretreatment before use, such as ultrasonic cleaning, annealing, or sandblasting, to eliminate internal stress and improve adhesion. 2. Molding and Processing
Multiple molding processes are employed to meet the needs of different components:
Stamping and Die-forming: Used for planar or curved components such as blast protection plates and armor plates. Precise control of die clearance and pressure ensures dimensional tolerances ≤ ±0.1mm.
Forging: Die forging technology is used to manufacture explosion-proof tools (such as explosion-proof wrenches). Copper alloys are forged in a single pass using a large press, significantly improving density, hardness, and service life, superior to traditional casting processes.
Laser Cutting and CNC Machining: Used for machining complex contours and high-precision mating surfaces, such as blast door sealing grooves. Surface roughness can reach Ra≤1.6μm.
Composite Reinforcement and Structural Optimization
Multi-material synergy enhances overall protective performance:
Laminated Composite: Alternating lamination of aramid-resin or ceramic-resin, with autoclave processing ensuring interlayer bonding strength ≥5MPa.
Fiber Wrapping: Used for riot control pipes or containers, with alternating circumferential/axial 45°/90° winding to enhance pressure and impact resistance.
Ceramic-Metal Composite: Achieved through active brazing or diffusion welding, achieving an interfacial shear strength exceeding 40MPa.
Assembly and Functional Integration
Sealing Assembly: O-ring compression is controlled at 15%-25%, and flange connections use torque wrenches to ensure preload deviation ≤±5%.
Modular Design: Modern riot control suits feature a detachable structure, supporting the addition of bulletproof cores, tactical rails, cut-resistant neck guards, and other functional components, enhancing combat adaptability.
Ergonomic Optimization:A honeycomb buffer layer disperses 60% of impact force, and a ventilation and suspension system improves comfort during extended wear.
Quality Inspection and Certification
All equipment must pass rigorous testing:
Stab Resistance Test: A 20-24 Joule kinetic energy vertical stab to a critical area must not penetrate with the blade tip.
Shock resistance test: No component breakage under 120-160 Joules of energy impact.
Environmental adaptability: Maintains stable performance in temperatures ranging from -30℃ to +55℃.
Certification standards: Complies with industry standards such as GA 420-2021 Police Riot Suit, and has passed the testing and certification of the Ministry of Public Security.
