SunJun Hardware is a professional high-precision sheet metal OEM manufacturer specialized in custom cabinet panels, chassis panels, equipment panel accessories and precision structural components for intelligent devices. We have overcome multiple common industry defects including thin-plate bending springback, flatness distortion, punching hole position deviation, welding deformation and inconsistent assembly tolerance. Our biggest exclusive advantage: We provide FREE professional drawing design according to your actual demands. Customers do not need to design or provide drawings by themselves. Our in-house engineering team completes structural design, DFM optimization and production drawing output fully on your behalf. With full-process independent production of laser cutting, precision punching, CNC bending and seamless welding, we guarantee ultra-high precision and stable batch consistency, helping global intelligent equipment and electrical manufacturers save R&D cost and shorten project cycle.
We are a full-process precision sheet metal manufacturer focusing on customized sheet metal components, communication cabinet housings and high-precision structural parts for intelligent automation equipment. We have overcome common industry bottlenecks: thin-plate bending springback deformation, cumulative assembly tolerance mismatch for multi-structure parts, welding thermal warpage, poor shielding consistency of communication chassis, unstable dimensional repeatability in mass production and coating adhesion defects. Equipped with in-house laser cutting, CNC precision bending, precision welding and standardized post-treatment workshops, we control tight dimensional tolerance and assembly matching accuracy strictly. We provide one-stop OEM & ODM customization services for communication manufacturers, intelligent equipment enterprises and automation system suppliers worldwide, delivering stable mass production, optimized structural cost and controllable delivery lead time.
We are a professional sheet metal manufacturer specializing in customized solar panel mid clamps, mid pressing brackets and mounting fixtures for distributed photovoltaic mounting bases. We effectively solve bending rebound, punching hole offset, uneven stamping forming and batch dimensional inconsistency common in solar accessory production. Strict tolerance control, anti-corrosion surface treatment and high structural rigidity guarantee long-term outdoor service life. We support drawing & sample OEM customization, stable mass production supply for solar system integrators and PV component manufacturers worldwide.
We specialize in custom precision sheet metal bending fabrication for energy storage and EV charger internal structural accessories. We overcome ultra-thin plate deformation, complex multi-angle bending tolerance deviation and small-position hole alignment difficulties during production. Strict dimensional consistency, flatness control and batch stability ensure your internal module brackets & protection housings fit perfectly with circuit components, supporting small sample trial orders and large-scale project mass production for global new energy manufacturers.
