Precision Injection Molded Housings & Enclosures — Custom Solutions for Your Product Protection Needs

At Weinengsi Technology, we specialize in the design and manufacture of high‑precision injection molded housings and enclosures that provide reliable protection, structural integrity, and aesthetic excellence for a wide range of applications. With over a decade of experience and a strong track record in European and American export markets, we deliver custom‑engineered solutions that meet the most demanding quality standards.

Our housing and enclosure manufacturing capabilities cover the entire production chain — from product development and mold design to injection molding, surface finishing, and final assembly. This end‑to‑end integration allows us to offer a seamless, one‑stop solution that reduces lead times, minimizes supply chain complexity, and ensures consistent quality at every stage.

Equipped with 10 imported FANUC high‑speed CNC machines, 60 injection molding machines, 8 mirror EDM machines, 7 wire EDM (slow‑speed) machines, and over 100 precision inspection devices including CMM systems, our 10,000m² modern facility is capable of handling projects of any scale — from prototyping to high‑volume mass production.

We offer a diverse range of housing solutions, including:

• Single‑Color & Two‑Shot Molded Housings — Seamless integration of rigid and soft‑touch materials in a single process

• Thin‑Wall Lightweight Enclosures — Material‑saving designs without compromising strength

• Complex Geometry Housings — Parts with undercuts, ribs, snap‑fits, screw bosses, and intricate internal features

• High‑Gloss & Textured Surface Finishes — Premium aesthetics for consumer‑facing products

• Impact‑Resistant & High‑Temperature Grades — Engineered with reinforced or specialty materials for demanding environments

With 160 experienced professionals, advanced CAD/CAM technologies, and a rigorous quality management system, we ensure that every housing and enclosure we produce delivers precision fit, durable performance, and consistent dimensional accuracy. Whether you are developing a new consumer device, an industrial control unit, or any product that requires a custom plastic housing, we are your trusted manufacturing partner from concept to delivery.

Partner with us — and let your product wear the protection it deserves.
