Explore our highly customized synthetic filaments and premium cosmetic and oral care tools engineered for global B2B clients.
The global beauty and personal care industry is witnessing a structural migration from natural hair fibers to engineered synthetic monofilaments. Today’s sophisticated B2B cosmetics brands demand materials that combine soft touch, structural memory, chemical resistance, and impeccable sterilization safety profiles. Engineered polymer lashes—such as PBT (Polybutylene Terephthalate) and customized co-polyester formulations—have become the undisputed industry standard due to their ability to hold curls, resist humidity, and deliver hyper-tapered tip morphology matching natural human eyelashes.
Additionally, consumer demand for clean beauty and green products has placed intense pressure on the raw material supply chain. Brands are actively seeking replacement materials that offer a reduced carbon footprint, high biocompatibility, and proven safety records. For industrial buyers, choosing a supplier with master batch formulation control is essential for maintaining product line differentiation and brand equity.
Established in 1991, Shenzhen Jiasheng Industrial Co., Ltd. started its journey as a pioneer in custom synthetic filaments production. In the early days, our primary R&D focus sat squarely on monofilament extrusion technology, supplying raw filaments to manufacturers of high-end hair brushes, toothbrushes, cosmetic brushes, and false eyelashes worldwide. Over nearly two decades of dedicated raw material formulation testing, we accumulated deep expertise in physical properties optimization, polymer thermal stabilization, and chemical tipping methodologies.
In 2008, recognizing that true product innovation happens when material science meets the end-user, Jiasheng vertically integrated its business model. By collaborating directly with downstream finished-product factories, we expanded our operational footprint to offer ready-to-market hair brushes, toothbrushes, premium makeup brushes, and meticulously crafted false eyelashes. This integration allows us to tightly align synthetic material characteristics with the final physical requirements of consumers.
Our unique ecosystem allows us to achieve unparalleled consistency in performance, cost, and design flexibility.
Most finished brush and cosmetic manufacturers buy their filaments from third-party extrusion companies. Jiasheng operates differently. By manufacturing our own synthetic filaments in-house, we control everything from raw polymer blending to tapering ratios, cross-sectional geometry, heat-resistance properties, and color tinting.
For B2B procurement partners, this translates to faster prototyping schedules, reduced raw material markup, and a zero-tolerance approach to quality drift. We can adjust the flexibility of custom PA46 or biodegradable filaments in real-time, matching the precise tufting machinery tolerances of our clients.
We combine Chinese engineering efficiency with strategically positioned Southeast Asian plants to buffer global trade risks.
As trade dynamics shift and protectionist measures rise worldwide, reliance on a single manufacturing source introduces supply chain vulnerabilities. Jiasheng addresses this by developing international production facilities outside of China.
Starting in 2024, Jiasheng initiated construction of dedicated production facilities in Thailand and Vietnam. By duplicating our high-precision extrusion and production machinery in these regions, we offer global clients a dual-origin supply safety net. This strategy guarantees tariff relief, maintains stable transport costs, and ensures business continuity for major consumer brands in the Americas and Europe.
Pioneering green cosmetics without compromising structural memory or application performance.
Our R&D team synthesizes bio-based and PCR (Post-Consumer Recycled) materials to combat standard plastics pollution. By incorporating PLA/PBAT blends and post-industrial waste streams, we provide bristles that maintain their curl retention while decomposing in controlled environmental conditions.
From initial design draft to final chemical tipping parameters, our OEM/ODM workflow guarantees absolute configuration control. We tailor the bristle diameter, tip length, cross-sectional profile (flat, round, hollow), and tensile stiffness to match client specifications.
How our custom filaments translate into market-leading consumer products.
Designed for salon environments where heat blowers are constantly utilized. Our specialized nylon filaments resist deformation at elevated styling temperatures.
Combines sustainably sourced wood with custom boar bristle blends. Ideal for gentle detangling and redistributing natural scalp sebum.
Featuring custom-curled nylon monofilaments configured to grip hair effortlessly without tangling or scratching the cuticle layer.
Engineered to match the powder pick-up of natural animal hair. Formulated with microscopic surface textures to grip and distribute makeup evenly.
Micro-tapered monofilaments designed for mascara brush heads. They stand up to chemical solvents and keep their shape after multiple uses.
Lighter-weight filaments that help eyelash curls hold their lift for longer. Engineered to reduce volume load while maximizing density.
Designed for sonic speed configurations. Features rounded bristle tips to protect gums while removing plaque effectively.
Tapered filaments featuring soft tip diameters down to 0.01mm. Provides deep interdental cleaning without irritating sensitive gums.
Features structural filament profiles with a stiffer base core and ultra-soft tips, combining robust scrubbing power with soft surface contact.
Proactive responses to trade barriers through local manufacturing facilities in fast-growing industrial zones.
Focuses on high-speed synthetic polymer extrusion, compounding raw materials for local cosmetic and packaging clients across ASEAN and Western countries.
Equipped with micro-tapering and brush tufting machines to supply finished toothbrushes and false eyelashes to international distributors.
Strategically located near deep-water shipping lanes, enabling fast customs clearing and reliable sea freight schedules to major global markets.
Crucial procurement, chemical, and design questions answered by our engineering department.
We primary use premium Polybutylene Terephthalate (PBT) and modified Nylon (PA46, PA612) polymers. PBT is highly favored for false eyelashes due to its low moisture absorption, excellent elastic memory, high dimensional stability, and curl retention when exposed to humidity and high temperatures.
By running both the raw polymer extrusion lines and the downstream brush/eyelash tufting assemblies, we remove middleman costs. Additionally, we can modify the raw material’s physical structure (such as tapering length or chemical composition) immediately if physical issues arise in downstream assembly trials.
Our plants in Thailand and Vietnam mirror the exact quality control, chemical mixing, and product design standards of our Shenzhen headquarters. This dual-source manufacturing model allows us to dispatch shipments from locations that bypass trade tariffs, lowering duty costs for North American and European brands.
Yes. We specialize in producing plant-based polymers and biodegradable filaments that decompose naturally in industrial compost environments. These eco-friendly options are perfect for sustainable cosmetic, hair brush, and toothbrush lines targeting eco-conscious consumers.
Standard custom production runs typically require 20 to 35 days from sample verification to export shipping. Customized tooling designs or specialized polymer compounding requests may add 7 to 10 days to the initial production schedule.
We run an ISO 9001:2015-certified manufacturing system. Laser measurement sensors monitor our monofilament extrusion lines in real-time, verifying diameter tolerances within micrometers to prevent variation between production batches.
Quality-engineered tools designed for reliable performance and strict regulatory compliance.
