Plastic Brush Molding

We specialize in manufacturing high-performance plastic components for industrial, household, and specialty brushes through advanced injection molding technologies. As a trusted supplier to cleaning tool brands, OEMs, and industrial equipment manufacturers, we deliver customized plastic brush parts that optimize functionality, durability, and cost efficiency. From mold design to semi-assembled modules, our services empower clients to create brushes tailored to sweeping, scrubbing, polishing, or precision cleaning applications.

Whether you need individual brush handles, heads, or fully integrated assemblies, our expertise in material science and high-volume production ensures compliance with FDA, REACH, and ISO standards.

Key Brush Structures & Customization Options

1. Brush Handle

Ergonomic Design:

Contoured grips (100–300mm length) with anti-slip textures (Ra 10–50μm).

Hollow structures for lightweight handling (wall thickness 1.5–3mm).

Overmolded TPE/TPU zones for shock absorption and comfort.

Material Options:

ABS (Acrylonitrile Butadiene Styrene): High-gloss finish for consumer-grade brushes.

Glass-Filled Nylon (PA6-GF30): Reinforced for heavy-duty industrial scrubbers.

Bio-Based PLA: Compostable handles for eco-friendly brands.

Surface Finishes:

Matte/glossy textures, dual-color molding, or laser-etched branding.

2. Brush Head & Bristle Mount

Core Components:

Bristle Anchors: Precision holes (0.3–2mm diameter) for nylon, PBT, or natural fiber bristles.

Reinforced Baseplate: Ribbed or honeycomb structures to prevent warping under pressure.

Material Precision:

POM (Polyoxymethylene): High rigidity and wear resistance for aggressive scrubbing.

PP (Polypropylene): Chemical-resistant for cleaning acid/alkaline solutions.

LCP (Liquid Crystal Polymer): Heat-resistant (up to 240°C) for autoclave sterilization.

3. Connectors & Hinges

Functional Customization:

Snap-Fit Joints: Quick-release mechanisms for replaceable brush heads.

Pivoting Hinges: 90°–180° rotation for adjustable-angle brushes (e.g., toilet brushes).

Material Choices:

PBT (Polybutylene Terephthalate): Low friction and creep resistance.

Self-Lubricating POM: Maintenance-free rotation in wet environments.

4. Specialized Attachments

Optional Features:

Squeegee Blades: Co-injected TPV edges for streak-free window cleaning.

Scraper Inserts: Stainless steel anchors molded into plastic heads.

Magnetic Mounts: Embedded ferrite cores for tool organization.

Advanced Injection Molding Capabilities

1. High-Precision Mold Design

Tooling Expertise:

Multi-cavity molds (up to 64 cavities) for mass production efficiency.

Hot runner systems to minimize material waste (<3% scrap rate).

Slide actions and lifters for complex undercuts (e.g., bristle anchor arrays).

Prototyping:

3D-printed functional samples in 48 hours for ergonomic validation.

2. Specialized Molding Techniques

Insert Molding:

Embed metal bristle anchors, RFID tags, or magnets during injection.

Two-Shot Molding:

Combine rigid PP brush heads with flexible TPE seals in a single cycle.

Microcellular Foaming:

Reduce part weight by 15–25% while maintaining stiffness.

3. Surface & Functional Enhancements

Performance Treatments:

Antimicrobial Additives: Silver-ion or zinc-based agents for medical brushes.

Low-Friction Coatings: PTFE layers on pivoting hinges.

Aesthetic Finishes:

In-Mold Decoration (IMD): Permanent logos or patterns.

UV-Resistant Pigments: For outdoor brush handles.

We are plastic mold maker and can provide custom mold service, we can make injection molds, blow molds, rotational molds and die-casting molds.

For custom injection molds, we can provide professional custom injection molding services. Usually Plastic brush Molding are manufactured using injection molding technology. The mold materials for injection molds can be chosen from P20, 718, S136, H13 and so on. The mold material reflects the mold life and product material requirements.

For parts that require blow molding production, we can also provide professional custom blow molding services.

Mold design:

Information you need to provide us

1. If you have drawings, 2D drawings, 3D drawings (preferably in STEP format).

2. If there are no drawings, you need to provide specific length, width, height and weight information. (It’s best to send us samples)

3. Should the mold be sent to your country, or leave the mold in our factory and we will help you produce the product.

4. Mold material requirements, cavity number requirements (you can tell us about the size of your injection molding machine)

Transaction process:

Mold testing:

Once the mold is complete, I do a mold test. It usually takes about 3-5 days to complete. We need to assemble the mold, adjust the pressure data of the machine, and try production. We need to check whether there are problems during the normal production of the mold and make modifications.
