Selling points

• Highly customizable in materials, color, finish, and branding — perfect for ODM/OEM fan programs.

• Precision injection molding ensures consistent fit, low flash and reliable assembly with internal components.

• Rapid prototyping to validate fit / airflow before tooling: 3D printing + CNC for fast iteration.

• Multiple surface-treatment options (soft-touch, plating, painting, printing) for premium aesthetics.

• Design for manufacturability (DFM) review included to control cost, cycle time and reduce tool rework.

• Flexible production scale: from small pilot runs to high-volume multi-cavity tooling.

High-quality services we offer

• Full ODM & OEM services: concept → DFM → prototyping → mold design & manufacturing → injection production → post-processing → assembly & packaging.

• Free DFM review and manufacturability recommendations to reduce cost and speed up time-to-market.

• Rapid prototyping: SLA / SLS 3D printing and CNC prototypes for testing fit and airflow.

• In-house tooling & mold maintenance: single to multi-cavity molds with hot runner options and precision machining.

• Surface finishing & decoration: painting, silk-screen, pad printing, laser engraving, plating, soft-touch coatings, and protective coatings.

• Assembly & value-added services: component insertion, ultrasonic welding, screw assembly, cable routing, QA inspection, and customized packaging.

• Supply chain & export support: packaging design, labeling, export documentation and coordination for global shipping.

(These are core capabilities commonly offered by WIN-WIN / Tiger Brother — see company product & service overview.)

Product quality & testing

We follow robust quality practices to ensure every fan casing meets customer specs and assembly requirements:

• Incoming material inspection (visual, material certificates, mechanical checks)

• In-process inspection during molding (first article checks, cavity balancing)

• Dimensional verification via calipers, gauges and CMM for critical features

• Surface quality control for texture, paint adhesion, printing alignment and plating finish

• Assembly & functional tests (fit checks with motor mounts, button/switch fits, airflow clearance)

• Final QC & packaging inspection — batch traceability and sampling plans can be tailored per customer needs

(We recommend specifying AQL sampling levels and critical measurement points during RFQ to align QC expectations.)

Product FAQs

Q: What materials are best for a portable fan housing?
A: ABS and PC/ABS blends are common for good impact resistance and surface finish; polycarbonate (PC) for higher heat and toughness; PP can be used for low-cost parts. Soft-touch TPE overmold is popular for grips. We’ll advise material choice based on thermal, mechanical, flame-retardant and aesthetic requirements.

Q: Can you produce branded finishes (logo, multi-color, chrome look)?
A: Yes — silk-screen, pad printing, laser engraving, spray painting, vacuum/chrome plating, and 2-shot molding for multi-color parts are all supported.

Q: What is the usual tooling cost and lead time?
A: Tooling cost varies by cavity count and complexity (single cavity vs multi-cavity, hot runner, slides). Typical lead time for mold build is 2–6 weeks for simple molds, longer for complex multi-cavity or family molds. We’ll provide a detailed quote after receiving drawings or samples.

Q: Do you offer samples and small pilot runs?
A: Yes — we produce prototypes via 3D printing / CNC and can run small pilot injection batches to validate product before full tooling investment.

Q: What information do you need to quote?
A: Preferred: 3D CAD (STEP/IGES), 2D drawings with critical dimensions & tolerances, preferred material, expected annual volume, target price, color/finish requirements. If you don’t have full drawings we can start from sketches or samples.

Q: What are typical MOQs?
A: MOQs depend on tooling and process. For injection molded parts, MOQ is often in the low thousands but smaller runs are possible depending on production scheduling and tooling amortization. Prototypes and small runs are available.

Q: Can you assist with compliance (RoHS/REACH) and material certificates?
A: Yes — material safety and RoHS/REACH-related documentation can be provided where applicable. Please specify compliance needs at RFQ.

How to order / next steps (quick)

1. Send existing 3D CAD (STEP/IGES) or sketches + target volume and finish requirements.

2. We provide a DFM review and quotation (materials, tooling estimate, sample & mass production pricing).

3. Approve prototype → tooling → sample approval → mass production.
