Preliminary Preparation: Clarify product requirements, design and manufacture high-precision molds, select and pre-process metal sheets (e.g., cutting, oiling).
Core Stamping: Use a stamping press and matching molds to complete processs such as blanking, punching, bending, and deep drawing, pressing the metal sheets into the target shape.
Post-processing: Remove burrs from the workpieces, conduct surface treatment (e.g., galvanizing, painting) as needed, and perform heat treatment for high-strength parts if required.
Quality Inspection and Delivery: Inspect dimensional accuracy (with calipers, coordinate measuring machines), appearance, and mechanical properties. Qualified products are packaged and delivered.
Design & File Preparation: Create 3D models (via CAD software like SolidWorks) of custom parts, then convert to CNC-readable G-code.
Material Selection & Setup: Choose suitable materials (e.g., aluminum, steel, plastic), cut to size, and fix them on the CNC machine’s workbench.
Machine Calibration: Adjust tool paths, set cutting parameters (speed, feed rate), and test-run to ensure accuracy.
CNC Machining: The machine automatically mills, drills, turns, or grinds the material into the target shape per the program.
Post-processing: Remove burrs, and conduct surface treatments (e.g., polishing, anodizing) if needed.
Quality Check & Delivery: Inspect dimensions and appearance; package and deliver qualified parts.
Material Preparation: Select metal sheets (e.g., steel, aluminum) and cut them into initial blanks via shearing or laser cutting.
Forming: Shape the blanks into desired structures using processes like bending (with a press brake) or rolling.
Joining (if needed): Connect multiple sheet metal parts through welding, riveting, or screwing.
Finishing: Remove burrs, then apply surface treatments (e.g., painting, galvanizing, powder coating) for protection and appearance.
Quality Inspection & Delivery: Check dimensions, shape, and surface quality; package and deliver qualified products.
Design & Specification Confirmation: Finalize custom parameters (size, thread type, material like stainless steel/steel, strength grade) and create 2D/3D designs.
Material Preparation: Cut metal bars (e.g., round steel) into blanks matching the part’s length/diameter.
Forming:For bolts/screws: Use cold heading (or hot heading for thick materials) to shape the head; for nuts: Stamp metal blanks into hexagonal (or custom) shapes.
Thread Processing: Cut internal threads (for nuts) via tapping, and external threads (for bolts/screws) via rolling or threading.
Surface Treatment: Apply anti-rust/protective coatings (e.g., galvanizing, chrome plating, zinc plating) as needed.
Quality Check & Delivery: Inspect thread accuracy, dimension, and coating; package and deliver qualified parts.

Spring toggle a versatile mechanical component designed to secure objects via elastic force, widely used in electronics, automotive, furniture, and DIY projects. Typically made from spring steel, stainless steel, or plastic, these clips feature a curved or bowed shape that creates tension when compressed, gripping parts firmly yet allowing easy removal. Common types include retaining clips (for shafts/holes), wire clips (for cables), and panel clips (for assembling furniture panels).
Corner braces, metal/wooden angled components, reinforce right-angle joints.
They boost structural stability, prevent warping or breaking in furniture, cabinets, or frames. Easy to install, durable, they’re widely used in home DIY, carpentry, and furniture assembly.
Barn door hardware is a stylish and functional system designed to hang and slide barn doors, blending rustic charm with modern convenience. Typically including tracks, rollers, hinges, and latches, it allows doors to glide smoothly along a horizontal track, saving space compared to traditional swinging doors. Materials range from steel for industrial looks to brushed nickel or bronze for sleek aesthetics, ensuring durability and corrosion resistance.
Trailer accessories enhance functionality, safety, and convenience. Essential items include hitch locks to prevent theft, trailer jacks for easy coupling, and winches for loading heavy cargo. Lights and reflectors ensure visibility, while tie-down straps secure items during transport.
