Your Reliable Custom Polycarbonate Enclosure Supplier in China
Traditional metal enclosures are prone to rust, while ordinary plastic enclosures tend to age and crack under intense sunlight.Zoycen’s Industrial Polycarbonate Enclosures utilize high-grade polycarbonate resin to address these shortcomings. They offer the durability of steel and are resistant to cracking, while eliminating concerns about weight or corrosion. Therefore, whether your project is exposed to heavy rain, intense sunlight, or prolonged chemical corrosion, our enclosures are perfectly suited to meet your diverse environmental requirements.
With over 15 years of manufacturing experience, Zoycen provides ready-to-install, custom polycarbonate enclosures through precision CNC milling, comprehensive customization, and rigorous automated quality inspections, ensuring your production line runs smoothly.
Features a simple screw-and-latch design for easy installation, making it ideal for tight, cramped spaces.
Equipped with hinges and stainless steel quick-release latches, these enclosures are well-suited for busy workshops, allowing for quick opening and closing to facilitate maintenance.
These enclosures feature transparent lids made of UV-resistant resin, allowing you to view gauges or inspect issues without opening the lid.
The internal slots are molded using injection molding technology, enabling quick snap-in mounting on DIN rails—ideal for automated systems.
Key Features of Polycarbonate Enclosures
The weight is up to 60% lighter than that of traditional metal or fiberglass computer cases. This not only saves shipping costs but also reduces the expenses for manual handling and installation.
Even under heavy impact, these polycarbonate enclosures remain stable and are not prone to cracking.
Operates reliably from -40°C to 120°C, with no performance issues in extreme heat or cold.
The screw holes inside the enclosure feature brass inserts, preventing stripped threads even after dozens of tightening cycles.
The rounded corners on the bottom prevent dust buildup, making the enclosure easy to clean and maintain.
No manual modifications are required upon receipt. Holes are drilled using precision instruments, and custom colors, logos, and dimensions are supported—truly ready to use right out of the box.
Precision CNC Cutouts, Ready to Use Right Out of the Box
Since wiring and installation vary for each project, Zoycen doesn’t just sell empty pc enclosures. Simply send us your sketch or CAD drawing, and we’ll use our factory’s precision cutting machines to pre-cut the cable-routing and button holes. Once you receive the product, no further work is needed—simply install your equipment and components. This not only saves you labor costs and significantly improves efficiency but also prevents enclosure cracks caused by improper drilling, which could lead to project delays or property damage.
Zero Signal Blockage,Continuous Signal
In outdoor environments, traditional metal or stainless steel enclosures completely block signals due to the nature of their materials, resulting in zero signal for smart devices and rendering them completely unusable. Our polycarbonate enclosures, however, do not have this issue. Wi-Fi, Bluetooth, 4G, and 5G signals can all pass right through without any signal loss. This allows you to safely tuck the antenna inside the enclosure, keeping it protected from the rain and preventing it from being damaged.

How Zoycen Solves Your Industry Challenges
Photovoltaic combiner boxes installed outdoors or on rooftops are exposed to the blazing sun every day. Metal enclosures can act like ovens, baking the internal components until they fail, while cheap plastic materials crack and yellow within less than two years. Zoycen tackles this major issue right at the source: We use UV-resistant modified materials and install automated vent valves directly at the factory. This allows the trapped heat and moisture inside the enclosure to escape naturally, preventing components and equipment from becoming damp, reducing costly maintenance expenses, and significantly extending the service life.
As is well known, seawater has a high salt content, which causes metal enclosures to corrode extremely quickly. Replacing control boxes at docks or on ships every year due to rust is a waste of both manpower and money. Zoycen’s professional-grade plastic enclosures are 100% rust-proof. We use fully automated dispensing machines to deeply embed seamless polyurethane sealing strips into the lid grooves, creating an absolutely airtight protective barrier. Even under continuous exposure to seawater and salt spray, the internal equipment remains completely protected, effectively eliminating the need for frequent maintenance.
Food processing plants use high-pressure water jets and highly corrosive disinfectants to rinse their entire production lines every day. Ordinary plastic enclosures, subjected to daily rinsing, are prone to water leakage or rapid aging and brittleness. Zoycen’s wash-resistant enclosures are molded from high-density, impact-resistant resin and are specifically designed to withstand disinfectants. Our polycarbonate enclosures can withstand high-pressure water jets from any angle, ensuring that not a single drop of water penetrates the interior, allowing your food production line to easily pass hygiene and safety inspections.
Most factory workshops are filled with invisible dust or oil mist. Traditional right-angle metal enclosures easily accumulate dust and are difficult to clean; over time, dust can seep inside the enclosure, causing short circuits and tripping the circuit breaker. Our engineering team has specifically designed smooth, rounded corners for Zoycen enclosures, allowing for easy cleaning with a cloth to remove dust and dirt. Additionally, the enclosures feature heavy-duty, embedded brass screw holes that prevent screws from loosening or stripping, even when exposed to prolonged, high-frequency vibrations from machinery. This ensures true micron-level dust protection and keeps machines running trouble-free.
Guarantee of Safety and Quality
Our quality control spans the entire process, with rigorous checks at every stage from IQC (Incoming Quality Control) to IPQC (In-Process Quality Control). Rather than conducting simple spot checks, we ensure that every enclosure passing through our facility undergoes 100% actual waterproof testing before shipment. Zoycen guarantees that every enclosure you receive is a flawless, ready-to-use product, significantly accelerating your project timeline.
We understand your concerns regarding freight transportation. Often, even a single damaged box during long-distance shipping can delay the entire progress of your project. Therefore, we exclusively use extra-thick, rigid, multi-layer cardboard boxes for packaging. We then place the goods on heavy-duty wooden pallets and secure them with stretch wrap. Even during long-distance transport or under harsh, bumpy conditions, not a single box will be damaged, ensuring your project schedule remains on track.
More Successful Client Results
1. Due to our later-stage project renovations and upgrades, we switched to using Zoycen’s industrial plastic boxes instead of metal ones. This reduced our initial material costs by 35%. Plus, the lightweight packaging lowered shipping costs, and we were able to customize the logo color and dimensions. Our project is now completely worry-free—it’s truly fantastic.
2. To meet our project needs, we placed an order for 3,000 crates with Zoycen. I was pleasantly surprised that, despite the large order volume, they were able to ensure consistent dimensional tolerances across all crates. There were no unexpected complications, which allowed our project to proceed on schedule. Thank you so much.
