Founded in 1991, Shenzhen Jiasheng Industrial Co., Ltd. began its path as a pioneer in polymer synthetic filament extrusion. Our initial research centered on structural optimization of filaments utilized across toothbrushes, makeup brushes, hairbrushes, and synthetic eyelashes. This deep technical foundation in material science served as our launchpad.
By 2008, recognizing that vertical integration leads to optimal quality control, we integrated our downstream processing operations. Through strategic partnerships and capital expansion, we unified material extrusion with finished product assembly. Today, this integration allows us to achieve unparalleled control over cycle times, cost structures, and customized structural configurations.
We bridge the gap between basic chemical engineering and consumer-ready personal care design.
Established in 1991, offering three decades of deep polymer research and finish-assembly engineering.
Operational manufacturing footprint across China, with upcoming facilities in Vietnam & Thailand.
Ready to deploy biodegradable filaments, FSC woods, and PCR plastics into high-volume product runs.
Providing multi-level customization, custom mold designs, and dedicated project management pipelines.
The performance of any personal care brush—be it an oral hygiene system, an eco-friendly hairbrush, or a professional cosmetic applicator—is fundamentally governed by the physics of its filaments. As an integrated manufacturer, Jiasheng approaches design from the molecular level. Below is the technical roadmap of the polymers we synthesize and transform:
Polyamide 46 (PA46) is characterized by an exceptionally high melting point (295°C) and superior crystallinity. This translated to unbeatable thermal stability and wear resistance, making custom PA46 filaments the preferred choice for industrial and high-temperature hair styling configurations where standard nylon deforms.
Synthesized from sebacic acid derived from castor oil, PA610 and PA612 offer reduced moisture absorption and exceptional elastic recovery compared to standard PA6. The structural resilience under wet conditions makes PA610/612 the gold standard for high-end toothbrush bristle arrays.
We infuse inorganic silver-ion and zinc-based antimicrobial compounds directly into the polymer matrix during the melt-spinning stage. This ensures a slow, controlled release of antimicrobial efficacy that is non-leaching, maintaining hygiene throughout the tool's usable lifespan.
Technical Insight: Standard nylons absorb water rapidly, leading to mechanical softening and loss of tuft retention. By utilizing long-chain synthetic polyamides like PA612 or high-density bio-polymers, Jiasheng maintains a wet bend recovery rate exceeding 92% (tested under ISO 20127 standards for brush stiffness and resilience).
By integrating the upstream production of raw synthetic filaments with downstream product manufacturing, we address the critical challenges of quality, speed, and cost efficiency.
Our raw material division focuses on tailoring density, taper angles, cross-sectional geometry (e.g., star, hollow, clover profiles), and color consistency. We engineer materials with precise mechanical thresholds to withstand advanced high-speed tufting equipment.
Our finished goods division translates raw materials into high-performance consumer products. Because we manufacture the fibers, we can optimize tuft density, anchoring depth, and face trimming geometries without relying on third-party raw material lead times.
Our primary manufacturing cluster in Shenzhen operates under Industry 4.0 methodologies. From automated polymer batching systems to robotic high-speed anchorless tufting machines, our systems minimize human intervention while maintaining tight tolerances. Key elements of our manufacturing efficiency model include:
Geopolitical changes and global trade barriers require responsive manufacturing partners. In response to these market needs, Jiasheng has diversified its production footprint to offer dual-sourcing options.
Our upcoming facilities in Thailand and Vietnam (initiated in 2024) provide international buyers with tariff mitigation and logistical options to protect against regional trade interruptions.
By coordinating production scheduling across our Shenzhen hub and our Southeast Asian manufacturing nodes, we can dynamically reallocate volume based on regional capacity demands.
All facilities run on the same ISO-9001 and BSCI compliance framework. The exact same polymers, raw materials, and extrusion quality standards are maintained globally.
As microplastic pollution continues to impact the global ecosystem, Jiasheng is committed to shifting from fossil-fuel-based single-use plastics to advanced circular alternatives. Our materials development department focuses on several key areas:
We process ocean-bound and consumer-recycled PET, PP, and ABS. Through cleaning, melting, and compounding, we regenerate these plastics into handles and components for brushes that match virgin plastic tensile profiles.
For temporary-use products, such as our travel toothbrushes, we offer biodegradable polymers blended with natural fibers (such as wheat straw and bamboo). Under industrial composting conditions, these materials degrade into carbon dioxide and water, reducing landfill accumulation.
We source FSC-certified black walnut, beechwood, and bamboo. These materials are treated with water-resistant bio-coatings to prevent splintering and mold growth in humid bathroom environments.
We provide customized configuration parameters across our three core product lines, allowing brands to tailor products to their exact market needs.
Featuring lightweight, ergonomically designed wooden structures with options for FSC certification.
Equipped with custom PA46 or specialized high-temp nylon fibers for salon-grade performance.
Utilizing high-performance elastomer membranes that maintain long-term structural rebound.
Engineered to replicate the micro-texture of natural animal hair, optimizing powder pickup.
Double-crimped construction using premium aluminum alloys to prevent shedding over long use.
Tailored configurations from 7-piece basic sets to comprehensive 24-piece professional kits.
Featuring naturally carbonized bamboo handles to prevent water staining and rot.
Precision-molded heads compatible with major ultrasonic platforms, using end-rounded PA612 bristles.
Combining dual-material injection molded handles with tailored bristle layouts.
Entering international retail markets requires meeting strict chemical and safety regulations. Jiasheng provides comprehensive validation documentation to ensure a smooth transition from production to store shelves:
All raw filaments, polymers, and color masterbatches are REACH and RoHS compliant, ensuring they are free from heavy metals, phthalates, and restricted substances.
Our toothbrush bristles and food-contact plastics comply with FDA material requirements, ensuring safety for daily oral hygiene applications.
Our production facilities regularly undergo BSCI (Business Social Compliance Initiative) audits, ensuring fair labor practices and safe working conditions.
We offer full chain-of-custody tracking for FSC-certified wood handles, confirming that raw wood materials are harvested from responsibly managed forests.
For corporate purchasing departments and major retail buyers, choosing a supplier involves evaluating risk, capacity, and supply chain logistics. Jiasheng tailors its operations to support professional sourcing teams through:
Our sales engineering team provides clear, detailed quotes that break down material costs, processing expenses, and packaging fees. This transparency helps sourcing managers conduct accurate cost analysis.
Every shipment is backed by a Certificate of Analysis (COA). We track production batches from raw monomer synthesis to final packaging, providing complete traceabilty in the event of QA inquiries.
With our new facilities in Thailand and Vietnam joining our Shenzhen hub, we support diverse delivery options including FOB, CIF, DDP, and multi-port consolidation to optimize shipping costs.
