Established in 1991, Shenzhen Jiasheng Industrial Co., Ltd. originally pioneered the manufacturing of advanced synthetic filaments. These precision engineering components formed the foundation for high-performance applications in hair brushes, professional toothbrushes, cosmetic applicators, and premium false eyelashes.
Driven by consumer insights and strategic alignment with downstream market shifts, we combined forces with manufacturing pioneers in 2008 to vertically integrate the production of completed consumer hair brushes, oral care systems, makeup brushes, and synthetic lash accessories. By engineering the bristles and product assemblies under one house, Jiasheng controls micro-level quality parameters that isolated assembly factories simply cannot match.
As plastic consumption issues urge global adaptation, we actively invest in recyclability, biodegradability, and bio-based plastics. Looking ahead to counteract geopolitics and trade barriers, Jiasheng is actively scaling operations with new manufacturing facilities under construction in Thailand and Vietnam for 2024.
The international custom hair care and personal hygiene market is shifting towards scientific scalp health, sustainable development, and resilient manufacturing. Major consumer concerns center on ergonomic, medical-grade detangling brushes, and chemical-free massage instruments. This transition changes structural requirements for custom B2B sourcing:
Global regulations on microplastics and carbon footprint targets force brands to replace virgin petroleum products. B2B buyers demand Post-Consumer Recycled (PCR) plastics, biodegradable PLA/PBAT polymers, and sustainable plant-based handle compounds.
Modern hair brushes are no longer passive styling tools; they are scalp wellness devices. Custom shapes, dual-bristle technologies (boar hair combined with nylon pins), and built-in liquid dispensers maximize scalp nutrient delivery.
Supply chain reliance on a single region exposes companies to trade tariffs and political gridlock. Multi-regional production centers (like Jiasheng's expansion to Thailand and Vietnam) offer duty mitigation and shipping versatility.
As a legacy manufacturer that began in raw filament extrusion in 1991, Shenzhen Jiasheng maintains precise expertise in polymer selection. The diameter, bend recovery, moisture absorption, and thermal resistance of bristles define the longevity and comfort of a brush. Here is how we engineer our industrial polymers:
PA6 & PA66 (Polyamide 6 & 66): Excellent tensile strength and high abrasion resistance. PA66 has a melting point of approximately 262°C, making it optimal for blow-dry styling brushes. However, PA6 and PA66 exhibit higher water absorption profiles, which can reduce bristle stiffness over time in humid shower conditions.
PA610 & PA612 (Polyamide 610 & 612): Premium filaments preferred for professional dental toothbrush heads and advanced hair brushes. Extruded with sebacic acid (derived from castor oil), PA610/612 features significantly lower moisture absorption (around 3% at saturation compared to PA6's 8.5%). This preserves structural stiffness, prevents bacterial colonization, and maintains memory bend recovery over long-term wet/dry cycles.
PA46 (Polyamide 46): Outstanding heat deflection temperatures (often exceeding 290°C). PA46 filaments are used in specialized heat-styler round brushes, where high-output salon blow dryers generate temperatures that deform standard nylon bristles.
Most custom hair care factories purchase their bristles from external chemical brokers. Jiasheng controls the extrusion process from plastic resin compounding to final brush tufting.
This integrated control loop allows us to modify filament diameters at the micron level, adjust colorants with food-grade pigment safety, and infuse antimicrobial ionic compounds directly into the polymer chain. By omitting intermediate suppliers, we secure structural quality while reducing raw material costs by up to 15-20%.
To address the global crisis of single-use and short-lived plastics, Jiasheng research and development works alongside global brands to deploy eco-engineered products:
Our facilities support deep physical customization. We collaborate with clients starting from visual sketching and CAD modeling to rapid 3D prototyping, mold development, and high-speed automatic bristle tufting.
Whether developing electrostatic-dissipative hair brushes, interchangeable sonic toothbrush heads, or cosmetic brush kits, our machinery can accommodate complex requirements like dual-injection molding, laser-engraved branding, and electroplated metallic finishes.
In today's trade climate, reliance on single-origin sourcing presents risks like tariffs, shipping bottlenecks, and shifting export policies. Shenzhen Jiasheng mitigation strategies focus on geographic manufacturing flexibility:
Expansion into Southeast Asia (Thailand & Vietnam in 2024): To optimize customs clearances, lower duty expenses for Western importers, and secure capacity against regional shutdowns, we established dedicated production hubs in Thailand and Vietnam.
These plants run with the same raw-material supply networks and automated assembly equipment as our Shenzhen headquarters. This dual-hub architecture provides buyers with flexible sourcing options: raw components and filament production in mainland hubs, or final product assembly and export out of Southeast Asian tariff-exempt ports.
Utilizing mathematical model software to design bristle maps. By testing simulated scalp resistance, we balance hair pulling with optimal scalp massage force, customizing bristle density for straight, wavy, and coarse hair textures.
Targeting a 100% circular product range by 2028. We are testing PLA-PHA co-polymers that remain heat-resistant up to 180°C under load, matching standard nylon styling durability while remaining fully ocean-degradable.
