Explore Our Sample Room: Die‑casting, Stamping, Injection Molding & CNC Machining Parts

Inside Our Sample Room – Precision Hardware Solutions Across Industries

Take a tour of the Runpeng sample room at our Shenzhen facility. Here you will find real samples produced for customers worldwide, covering die-cast parts, precision stamped components and CNC-machined products across a wide range of industries. Every piece on display represents a completed project – proof of our manufacturing capability, quality standards and one-stop customization service.

 Die-Cast Samples

Our sample room features a wide range of zinc alloy and aluminum die-cast products, including door hinges, handle bases, protective rosettes, push bar fittings, decorative hardware covers and automotive brackets. Produced on our high-pressure die casting machines, these samples demonstrate fine surface detail, consistent dimensional stability and excellent casting integrity – ready for polishing, plating, anodizing or powder coating.

⚡ Precision Stamping Samples

From thin sealing profile accessories to structural metal brackets, our precision stamping samples cover progressive die stamping, deep drawing and blanking parts in steel, stainless steel, aluminum and brass. Customers rely on us for high-volume production with tight tolerances, flatness control and burr-free edges – ideal for gaskets, shims, contacts and hardware components.

⚙️ CNC-Machined Samples

Equipped with 3-axis and the latest Mazak 5-axis machining centers, we produce complex, high-precision components in aluminum, stainless steel, brass, copper and engineering plastics. Our CNC samples include machined door handle mechanisms, custom hinge pins, valve parts, sensor housings and prototype components – all delivered with micron-level accuracy and excellent surface finish.

 One-Stop Customization – From Drawing to Finished Product

What sets Runpeng apart is our ability to handle an entire product under one roof. Customers send us a drawing or a sample, and we manage the complete production chain:

• DFM analysis & engineering support – our engineers review your design for manufacturability and cost optimization
• Tooling & mold making – die casting dies, stamping dies and injection molds built in-house
• In-house production – die casting, stamping, CNC machining, injection molding and profile processing
• Surface finishing – polishing, electroplating, anodizing, powder coating, PVD and more
• Assembly & packaging – full assembly, functional testing and customized packaging before shipment

 Products for Every Industry

Over the years, we have customized hardware and precision components for customers across many sectors – including:

• Door & window hardware – hinges, handles, locks, sealing profiles, push bars
• Automotive & transportation – interior trim parts, brackets, sensor housings, fasteners
• Furniture hardware – drawer fittings, connectors, decorative metal and plastic components
• Consumer electronics – precision enclosures, shafts, buttons and structural parts
• Industrial equipment – custom brackets, valve components, mounting parts

No matter what industry you are in, if you need custom metal or plastic components, chances are we have produced something similar – and we are ready to support your next project with the same reliability.

✅ Quality You Can Trust

Every sample in our room represents parts that have passed our strict quality control – including CMM dimensional inspection, salt spray testing, hardness testing and functional endurance checks. We work to ISO-based quality management and support international standards such as EN 1935 for door hardware. When you partner with Runpeng, you get not just a supplier, but a manufacturing partner invested in your product's success.
