A one-stop solution integrates all product development stages under a single provider, from design and prototyping to production, finishing, and delivery. It simplifies processes, reduces lead time, and ensures consistent quality.
At Yijiang, we leverage over a decade of experience in precision manufacturing and injection molding. Our advanced facilities, including high-precision CNC machines, injection molding lines, and quality inspection systems, allow us to handle complex projects efficiently.
Our in-house engineering team provides expertise in mold design, material selection, and process optimization. This ensures that every project benefits from technical excellence and innovation.
Yijiang provides end-to-end injection molding services for small, medium, and large-scale plastic components.
From custom mold design and precision injection to multi-material molding and automated handling, we deliver high-quality, consistent, and efficient production for diverse industries.
Injection molding melts plastic at controlled temperature and injects it into mold cavities under high pressure. After cooling and solidifying, precise parts are produced efficiently. Ideal for high-volume production of small to medium plastic components.
Specialized for oversized components with large surface areas or long dimensions. High-tonnage injection machines, reinforced molds, and precise process control ensure uniform filling, consistent wall thickness, and stable quality. Suitable for automotive panels, battery bases, and industrial housings.
Beyond injection molding, Yijiang provides mold design, mold fabrication, prototype development, and post-processing services, offering complete support for custom plastic components.
