Redefining Manufacturing Efficiency: Foshan Dingyi Industrial Technology Co., Ltd. Empowers Midea Microwave Oven BPO Project with Stamping, Welding, and Spraying Expertise

Amid the global shift toward specialized division of labor and refined operations in manufacturing, Foshan Dingyi Industrial Technology Co., Ltd. (abbreviated as Dingyi Industrial) has emerged as Midea Group’s first strategic partner in exploring the in-house factory BPO model, leveraging its technical prowess in stamping, welding, and spraying—three core manufacturing processes. We deliver end-to-end services for Midea’s microwave oven factory, from R&D to finished product delivery, and redefine the "results-oriented" standard for appliance manufacturing outsourcing with a daily output of 130,000 door bodies and 150,000 cavities.

I. Midea Group’s First In-House Factory BPO Project: Results-Driven Deep Collaboration

As Midea Group’s first case of outsourcing core in-house factory processes, Dingyi Industrial undertakes the full-process BPO services for stamping, welding, and spraying at its microwave oven factory, with a commitment to end-to-end results accountability. From raw material inbound to finished product outbound, we manage technical design, production control, and quality inspection—allowing Midea to focus on branding and R&D without worrying about manufacturing efficiency or quality.

Key Project Metrics:

Daily Output: 130,000 microwave door bodies + 150,000 microwave cavities, meeting Midea’s global large-scale supply demands;

Delivery Standards: First-pass yield ≥99.8%, on-time delivery rate 100%—far exceeding industry averages.

II. Three Core Process Capabilities: Technical Backbone for High-Efficiency Production

1. Stamping: The "Precision Shaper" with Millimeter-Level Accuracy

As the "birthplace" of microwave door bodies and cavities, our stamping process is renowned for high speed, precision, and stability:

Equipment Portfolio: Equipped with 1,200-ton high-speed presses and servo presses, enabling fully automated(coil material) uncoiling to finished product stamping;

Accuracy Control: CCD vision inspection systems ensure stamping part dimensional tolerance ≤±0.01mm, perfectly matching assembly requirements for internal microwave components;

Material Adaptability: Expertise in stamping galvanized steel, stainless steel, and aluminum alloys. Optimized mold design for microwave lightweighting needs boosts material utilization by 15%.

2. Welding: Dual Guarantee of Structural Strength and Production Efficiency

Welding quality directly determines microwave cavity sealing and service life. Our welding technology balances speed and strength:

Automated Welding Systems: 20+ KUKA/FANUC robotic welding workstations with laser welding + resistance spot welding hybrid processes reduce single-cavity welding cycles to 12 seconds;

Quality Control: Ultrasonic flaw detection for every weld eliminates microcracks and cold joints, ensuring cavities withstand over 100,000 openings/closings without deformation;

Flexible Production: Supports mixed-model cavity welding with quick mold changes to adapt to Midea’s new product iterations.

3. Spraying: The "Final Mile" of Aesthetics and Durability

Spraying is not just about appearance—it’s a critical protective layer against corrosion and scratches. Our spraying process balances environmental friendliness, consistency, and customization:

Fully Automated Spraying Lines: 5-stage pretreatment + electrostatic powder coating systems enable unmanned operation from degreasing and ceramic conversion coating to curing, with coating thickness deviation ≤5μm;

Eco-Friendly & High-Performance: VOC-free powder coatings meet RoHS and REACH standards, with coating hardness ≥2H and salt spray resistance ≥480 hours;

Customizable Finishes: 20+ surface treatments (matte, high-gloss, metallic) to match Midea’s regional brand visual requirements globally.

Note: Ceramic conversion coating is an eco-friendly upgrade from phosphating. It forms a nano-ceramic film to enhance substrate adhesion and corrosion resistance, with zero phosphorus emissions—aligning with EU RoHS and other environmental standards, and highlighting advanced, sustainable manufacturing.

III. Why Choose Foshan Dingyi Industrial Technology Co., Ltd.? Three Core Advantages of Global Manufacturing Services

1. BPO Compliance: Aligned with Global Market Standards

Dingyi Industrial’s production system is certified to CE (EU), UL (North America), and ISO 9001 standards. We adjust process parameters for target markets (e.g., UL fire safety standards for North America, EU environmental requirements) to ensure products meet local access criteria directly.

2. End-to-End Transparency: Digitally Driven Result Control

Midea uses our self-developed Manufacturing Execution System (MES) to real-time monitor production progress, quality data, and equipment status—enabling full visibility from order to delivery and true "results-oriented" outsourcing collaboration.

3. Flexible Capacity: Scalable to Demand

Whether for daily orders of 100,000 units or million-unit stockpiles for new product launches, Dingyi Industrial’s BPO model quickly adjusts production layouts and staffing to ensure capacity flexibility and delivery stability.

IV. Conclusion: Empowering Global Manufacturing Partners with Process Excellence

The collaboration between Dingyi Industrial and Midea is more than manufacturing outsourcing—it’s an upgrade to "specialists doing what they do best" in industrial division of labor. With stamping, welding, and spraying as our core pillars, we provide results-accountable BPO services to global clients in home appliances, automotive, and electronics. Let your brand focus on innovation—leave manufacturing efficiency and quality to us.
