Explore our primary manufacturing line featuring next-generation filament extrusions, ergonomic designs, and sustainable components engineered for global brands.
Founded in 1991, Shenzhen Jiasheng Industrial Co., Ltd. originated as a pioneer in high-precision synthetic filament extrusion. Our filaments became foundational elements across the personal care and cosmetic sectors—serving as primary components in professional makeup brushes, premium dental care systems, hair grooming tools, and cosmetic lashes.
Driven by a philosophy to get closer to downstream demands and understand modern consumer habits, Jiasheng strategically integrated downward in 2008. By partnering with leading manufacturers, we built a fully integrated ecosystem spanning raw monofilament engineering to high-speed automated packaging of finished products.
Today, as dynamic regulatory changes and consumer preferences demand sustainable alternatives, we lead the industry by shifting production paradigms towards post-consumer recycled (PCR) resins, bio-degradable fibers, and low-footprint packaging structures. To mitigate geopolitical risk and offer structural customs benefits, Jiasheng is actively executing a multi-regional production setup in Thailand and Vietnam.
Decades of chemical development combined with automated vertical manufacturing systems empower our corporate partnerships.
By producing our own synthetic filaments in-house, we eliminate standard middle-tier markups and tightly control bristle thickness, elastic recovery, and antimicrobial qualities. This direct integration guarantees consistent batch quality and shortens experimental prototyping time from months to days.
We actively utilize bio-based PLA, wood-plastic composites (WPC), and PCR thermoplastics to construct brush bodies and handles. By reducing fossil-fuel dependence, we support our Fortune 500 clients in meeting their Scope 3 greenhouse gas reduction goals.
Modern procurement directors face unprecedented volatility: rising container costs, fluctuating duties, and tightening environmental restrictions (such as Europe's PPWR and US state-level microplastic laws). Sourcing makeup tools and oral care accessories from disjointed workshops creates quality variances and compliance risks.
Jiasheng's Unified Solution: We offer a consolidated sourcing environment where raw filament extrusion, plastic injection molding, tufting, ferrule stamping, and packaging occur within a single audited infrastructure. Our upcoming manufacturing locations in Thailand and Vietnam allow clients to bypass regional tariffs, streamline custom clearance, and optimize transport costs.
Our upcoming production facilities in Thailand and Vietnam are designed to replicate the strict manufacturing standards of our main Shenzhen plant. This helps global brands diversify their sourcing, protect against tariff changes, and keep logistics costs manageable.
Our product roadmap focuses on balancing environmental sustainability with top-tier performance. Makeup brushes must retain liquid formulas without absorbing them, and toothbrush bristles need to maintain bend recovery over months of wet use.
Integrating raw material synthesis with finished product manufacturing lets us control quality at every step. In our testing labs, we check filament tensile strength, abrasion resistance, and bend recovery to ensure high-performance durability.
Cleanroom environments and automated assembly lines keep product quality consistent. Automated vision systems inspect every cosmetic brush ferrule and replacement toothbrush head, ensuring clean packaging and zero defects before shipment.
We offer customized, eco-friendly manufacturing services across three distinct product divisions.
As import policies change and global consumer brands focus on supply chain resilience, Relying on single-country production can create compliance bottlenecks. To address this, Shenzhen Jiasheng is actively setting up regional production bases in Thailand and Vietnam.
These new facilities mirror our main China facility, including identical filament extrusion machines, automated German tufting setups, and cleanrooms. By building this multi-country manufacturing system, we offer our partners dual-sourcing options, lower tariff exposures, and flexible delivery paths during peak shipping seasons.
We follow rigorous manufacturing standards to ensure every batch meets international retail requirements.
With over 30 years of experience in polymer extrusion, we refine filament diameters down to ±0.01mm, ensuring consistent softness, recovery, and color matching.
We comply with European REACH and RoHS standards, and our toothbrush and cosmetic lines are FDA-registered, BPA-free, and ISO 9001 certified.
Because we produce our own monofilaments, we avoid contaminated polymers and ensure trace materials are fully tracked from supplier to shelf.
