Product Description

Product Description

We specialize in precision CNC processing services, using various materials such as aluminum (6061-T6, 7075-T6), brass, stainless steel (304, 316), low-carbon steel, and various plastics like ABS and Delrin. Our processes include CNC milling, turning, grinding, drilling, etc., with tolerances up to 0.002 millimeters.  With 17 years of experience, we hold ISO9001 and ROHS certifications, ensuring top-notch quality. Production capacity varies depending on complexity and quantity, and the delivery time is typically 7-15 days. Packaging includes pearl cotton, bubble bags or pallets for bulk orders. Delivery options include express, air freight or sea freight. Payment terms are flexible, and the minimum order quantity meets the needs of buyers.
Our machining service excels in custom processing. We handle a wide range of materials, from brass to stainless steel. Whether it's precision - turned brass connectors (like the golden cylindrical parts with threads) or intricately shaped stainless - steel needles and screws, we tailor the machining process to your exact specifications.
For unique geometries, tight tolerances, or special surface finishes, our advanced equipment and skilled technicians work together. We start from understanding your design needs, then plan the cutting, turning, milling, and other operations. Every step is adjusted to ensure the final machined parts, whether simple or complex, match your custom requirements perfectly, helping you bring unique industrial components to life.

Packaging & Shipping

I. Preparations before Packaging
1. Casting pre-treatment
Surface cleaning: Remove the molding sand, burrs and oil stains from the surface of the casting, ensuring no residual impurities (using shot blasting or chemical cleaning).
Anti-rust treatment: Customized protection plan based on transportation environment:
Maritime transportation / High humidity environment: Spray epoxy zinc-rich primer + polyurethane topcoat (coatingthickness ≥120μm).
Short-term storage: Apply economical anti-rust oil for temporary protection.
Drying treatment: Ensure that the moisture content of the castings is ≤ 0.5%, to prevent internal rusting.

II. Core Packaging Process and Details
Individual protection
Edge protection: Hard edges are covered with EPE pearl cotton or custom foam corner protectors (thickness ≥20mm) to prevent puncturing the box.
Precision surface coating: Apply fluorocarbon spray to the surface and cover it with a PE protective film (such as for revolving door ceiling panels) to prevent scratches.
Moisture-proof measures: Place silica gel desiccant inside the box (quantity: 1kg per cubic meter) or adopt a perforated design (the stainless steel castings need to be breathable to prevent condensation).

2. Internal reinforcement design
Buffer filling: Fill the gaps with foam beads, paper scraps or air cushions to ensure that the casting does not shift. Load-bearing support: For overweight components (such as 70-kilogram castings), a "calcium plastic hollow board + directional reinforcing ribs" structure is adopted, which increases the load-bearing capacity by 40%. Layered isolation: When stacking in multiple layers, use solid wood pillow blocks for separation to prevent component collisions (such as in the packaging of rotating door profiles).

3. External Packaging
Box structure:
Wooden box: Five-layer composite board (thickness 0.9 cm) + metal snap fasteners for locking, with steel frame reinforcement at the bottom.
Calcium plastic box: Modular assembly, empty box can be folded to save storage space.
Sealing treatment: The top of the box is covered with double-laver moisture-proof film, and the seams are sealed with waterproof adhesive tape.
ldentification Specifications:
Printing enterprise logo, casting name/number, center of gravity symbol , rain protection sign.
Attach warning labels (such as"Sharp Edges") and hoisting indication marks.

FAQ

Q: Are you a factory or a trading company?

A: We are a company that integrates industry and trade. We own several factories and have specialized in casting parts and CNC processing parts for many years.
