WPC series — product category

WPC series

It is a new type of composite material formed by thermoforming process under high temperature and high pressure conditions. Core advantages: Resistant to bad weather, anti-aging, anti-corrosion, anti-cracking, anti-termite, and moisture-proof; it also has high dimensional stability (not easy to deform under temperature differences/humidity changes), strong impact resistance, and no harmful volatile substances such as formaldehyde (in compliance with E0-level environmental standards). At present, wood-plastic composite materials are widely used in various decorative materials such as door covers, door cover lines, skirting lines, louvers, and wall panels for interior decoration.

Cabinet Series — product category

Cabinet Series

Sealing components for household and industrial cabinets, achieving precise sealing for different application scenarios through the matching of materials and cross-section designs. Household cabinets focus on dustproof, silent and moisture-proof; industrial cabinets (such as electrical cabinets) emphasize weather resistance, waterproof and dustproof, mostly using U-shaped grooves or skeletoned sealing structures to meet higher protection levels.

Buyer FAQ (excerpt)

MOQ, lead time, materials, colours, samples, OEM/ODM, and packing — answered from our published factory information.

We offer a range of materials for different sealing applications, including EPDM, silicone, PVC, TPE, TPV, NBR, and other custom rubber or plastic compounds. The material choice depends on the required performance, such as weather resistance, temperature resistance, flexibility, compression performance, food-grade compliance, or oil resistance.

The correct sealing strip depends on several factors, including application environment, installation method, profile shape, hardness, temperature range, and required sealing performance. For example, EPDM is often used for outdoor door and window sealing, while silicone is preferred for high-temperature or food-contact applications. If you provide drawings, samples, or application details, we can recommend a suitable solution.

Yes. We support custom extrusion, OEM, and ODM production. We can manufacture sealing strips and sealing components based on your drawings, samples, dimensions, hardness requirements, color preferences, and application needs. Custom tooling and profile development are available for new projects.

For an accurate quotation, we usually need product drawings or samples, profile dimensions, material requirements, hardness range, color, quantity, application, and any special requirements such as flame resistance, adhesive backing, or packaging. The more complete the information, the faster and more precise the quotation will be.

Yes. Sample support is available for material confirmation, profile testing, and application evaluation. Standard samples can usually be arranged quickly, while custom samples may require tooling or trial production time depending on the profile complexity.
