What Is Yundu’s Air Cushion Filling Machine? BB Cream Filling

Yundu is a premier Chinese manufacturer of liquid filling machinery with over 20 years of experience in cosmetics, pharmaceuticals, and food packaging. The company designs and builds all its machines in-house, focusing on value and reliability for customers. Its portfolio includes bench-top fillers, piston fillers, and high-speed automated lines. Among these are specialized foundation (cushion) filling machines – often called air-cushion-filling-machines – built to handle liquid foundation, BB/CC creams, and cushion cosmetics with precision. Yundu’s equipment is known for consistent, high-quality dosing and easy operation.

Air-cushion makeup compacts (as shown above) have become hugely popular worldwide. In 2025 the global air-cushion foundation market reached about \$2.8 billion and is projected to hit \$4.6 billion by 2034 (≈6.8% CAGR). This boom is driven by the spread of Korean and global beauty trends and demand for portable, buildable-coverage products. In a cushion compact, a liquid foundation is stored in a sponge-lined “cushion” that releases product when patted with a puff. This format offers convenience and hydrating finish, but it also poses hygiene challenges – in fact, one study found reusable cushion compacts had a 20.0% bacterial contamination rate (versus only 2.8% for pump/tube containers). High-quality filling machines (and clean processes) are therefore essential to ensure safety and consistency.

Yundu’s cushion/foundation fillers are tailored solutions that meet these challenges. For example, the YD-1S Single-Color Cushion Filling Machine is a high-precision, semi-automatic system designed for small to medium cosmetic brands. Yundu engineered the YD-1S to dispense exact volumes of BB/CC cream or liquid foundation into each cushion cup. An operator loads empty cushion cases on the table, and the machine’s servo-driven piston pump delivers a precise dose to the inner cup. After filling, it automatically inserts and presses the sponge cushion and locks on the middle ring to seal the unit. This ensures each compact is filled uniformly and hygienically. The YD-1S is compact in size, easy to clean (all wet parts are SUS304 steel), and its mold plates can be changed quickly for different cushion sizes. In normal operation it fills on the order of 16–24 compacts per minute (about 1,000–1,440 per hour).

For higher throughput or special effects, Yundu offers multi-head cushion fillers. The YD-2Q Multicolor Filling Machine uses two filling heads to create 2-color or gradient cushion designs. It automates the full process: after inner cups are placed, the dual pumps dispense BB/CC cream or foundation in coordinated swirl patterns, then the sponge and ring are pressed and a top label applied. The YD-2Q reaches about 1,500–2,000 compacts per hour at full speed, with ±0.3 g fill accuracy.

For maximum output, Yundu’s rotary machines like the YD-4QT integrate four filling heads on a 16-station turntable. This multi-color system can churn out 2,600–3,000 compacts per hour. It includes automatic labeling (top and bottom) and can handle very thick creams (up to ~40,000 mPa·s viscosity) and dense sponges. These quad-head systems support complex designs (up to 3–4 colors) and include fast mold changeovers for quick batch swaps.

Key Features: Yundu’s cushion foundation fillers share core strengths:

• High Speed & Accuracy:They use servo-driven piston pumps for precise volumetric filling. Accutek notes that piston fillers excel at moving viscous products with controlled, repeatable dosing. In practice, even Yundu’s smaller machines fill over 1,500 units/hr, while full-scale multi-head systems reach up to 7,200 units/hr (120/min). Such throughput comes with tight weight tolerances (typically ±0.5% or better).
• Versatile Operation:The machines adjust easily for different cream types, weights, and cushion sizes (usually 30–100 mm diameter, 10–80 mm thick). Fill volumes can range from a few grams up to ~25 g per compact. Multi-color fillers include quick-clean manifolds for fast color changes. This flexibility lets brands produce single-color foundations or trendy marble/camo cushions on the same line.

• Hygienic Design:All product-contact parts use food-grade stainless steel (#316 or #304). The equipment meets GMP standards and can include options like UV sterilization or nitrogen blanketing. As noted, cushion compacts can trap bacteria more easily than sealed pumps, so features like closed-loop filling and easy washdown are crucial. Yundu’s machines minimize contamination risk with sealed pistons and quick-clean parts.
• User-Friendly Controls:Yundu equips these machines with touchscreen PLC panels for recipe control. Many operations are automatic (cup placement, sponge pressing, ring pressing, sealing, labeling, and box collection). Despite their complexity, the machines have intuitive interfaces and German-brand components (Siemens/Omron/Schneider) for reliability. Operators can learn to run a machine in minutes, reducing downtime during staffing changes.
• Support & Sampling:Yundu emphasizes strong customer service. According to Sales Manager Luna, “We have extensive experience with air-cushion filling machines. You can simply send us your sample product, and we will run free sample fills until you are satisfied.” Yundu can quickly prove its performance on a client’s actual formula. Luna adds that Yundu offers a variety of models (single-head to multi-head) and will help customers choose the right one. “In the industry, our filling machines are absolutely leading,” she notes, reflecting Yundu’s confidence in its cushion-filling expertise.

Below is a comparison of Yundu’s single-head and multi-head cushion-filling machines:

Yundu offers both rotary and linear cushion-filling systems. The machine above (YD-4QT) integrates four servo-driven fill heads with sealing and labeling stations. Its 16-station rotary table handles automatic cup loading, multi-color cream filling, sponge pressing, ring pressing, and top/bottom labeling.

Such an all-in-one line delivers finished cushion compacts with no manual steps, making it ideal for cosmetic factories producing high-quality BB/CC cushion products at scale.

Sales Manager Insight: Yundu’s Sales Manager Luna emphasizes the company’s customer focus. “We have extensive experience with air-cushion filling machines,” she says. “If you send us your formula or sample compact, we will run free trial fills until you are satisfied with the result.” Luna points out that Yundu offers many models (from single-head to multi-head configurations) so customers can pick the right speed and style. “In the industry, our filling machines are absolutely leading,” she adds, reflecting Yundu’s confidence in its technology and service.

In short, a Yundu foundation (air-cushion) filling machine is a specialized cosmetic filler engineered for filling cushion makeup compacts with precision. These systems combine controlled pumping and mechanical assembly to automate BB/CC cream or liquid foundation into a sponge, then seal the compact.

For example, even the basic YD-1S achieves consistent volume control with minimal waste, while the YD-4QT quad-filler runs 2,600–3,000 units per hour. Built with 316 stainless steel parts, German electronics, and 20+ years of R&D behind them, Yundu’s machines ensure safety and efficiency in every batch.

To meet diverse needs, Yundu provides full line solutions and support: it can design a one-off prototype or integrate a cushion filler into a complete packaging line. With free sampling and expert guidance, Yundu helps cosmetics companies quickly scale up cushion foundation production.
