HC-Air cabin filter supplier
The Brazilian client is a growing automotive filter manufacturer based in São Paulo, supplying the domestic aftermarket and regional OEM service networks across MERCOSUR. With Brazil’s tropical climate — high humidity, heavy pollen, and long dry seasons with dust — demand for cabin air filters is rising steadily. Their existing semi-automatic production relied on 7–8 operators per shift and suffered from inconsistent edge banding on activated carbon media, high trimming rejects (around 4%), and slow mold changeovers between popular local models (Chevrolet Onix, Fiat Argo, VW Polo, Hyundai HB20).
Seeking to modernize, the client’s Production Director flew to China to evaluate suppliers. After reviewing several options, they chose Hengchao for an in-person factory visit and in-depth discussion with the company’s leadership.
2. Factory Visit: Automation on Full Display
Upon arrival at Hengchao’s Guangzhou facility, the Brazilian delegation was welcomed by Mr. Peng, General Manager of Hengchao, and the senior technical team. The visit began with a walk through the production workshop, where the client’s eyes were immediately drawn to the signature green-and-white cabin filter machine line in operation.
The Brazilian team watched as the line ran through its full automatic cycle:
- Servo pleating with auto tension control on charcoal composite media
- Hot-melt frame bonding laying a clean, even bead
- Edge banding locking the frame without overflow
- Precision trimming dropping neat white scraps onto the green workshop floor
The client’s Production Director paused by the circular observation window, observing the internal mechanisms while a Hengchao engineer fine-tuned the glue dispensing head. He turned to Mr. Peng and said:
“This is the first time I’ve seen a cabin filter line that truly runs itself. In Brazil, we struggle with manual inconsistency. Here, the machine does everything — pleating, gluing, trimming — with almost no human touch. This is the level of automation we need.”
3. Negotiation with Mr. Peng
After the workshop tour, both sides moved to the conference room for a formal meeting. Mr. Peng presented Hengchao’s corporate philosophy and 2026 roadmap, emphasizing three core strengths:
- Smart Automation: Every machine is designed for minimal labor dependency — the cabin filter line requires only 2 operators per shift, down from 7–8.
- Global Adaptability: Portuguese-language HMI, 220 V / 380 V / 60 Hz motor configuration (standard for Brazil), and CE-design electrical compliance.
- Media Versatility: Compatible with non-woven, HEPA, and multi-layer activated carbon media, handling the humidity and dust challenges of the Brazilian market.
The Brazilian client shared their expansion plan: doubling cabin filter output within 18 months to capture growing aftermarket demand. Mr. Peng responded with a tailored proposal — not just a machine sale, but a long-term partnership including remote PLC diagnostics, spare parts stocking advice, and lifetime technical support.
The atmosphere was warm and constructive. The client nodded repeatedly as Mr. Peng detailed the quick-changeover system (under 30 minutes between Onix and HB20 sizes) and the reject-rate guarantee (below 0.8%).
“Mr. Peng, your workshop speaks for itself. The automation level here is world-class. We’ve visited other factories, but Hengchao is the only one where I saw the machine, saw the results, and felt zero doubt.”— Production Director, Brazilian Client
