Casting Service

As an important supplement to our full-process customization system, casting technology realizes one-time integral forming of thick metal structures, solving the shortcomings of traditional processing such as material waste, weak splicing strength and complicated production procedures. Wanluo factory provide full-type casting OEM & ODM services including investment Casting Service, sand casting and die casting for rigging hardware, mechanical accessories, engineering parts and industrial equipment components, delivering high-strength, high-toughness and complex-structured custom metal products for global industrial customers.

Core Process & Production Technical Advantages

We adopt mature integrated casting production technology, equipped with professional melting furnaces, precision casting molds, cooling forming systems and post-processing finishing equipment. By melting raw metal materials and pouring them into customized precision molds, the products achieve one-time integral forming with complete and dense metal internal structure, no internal gaps or splicing traces. Strict temperature control and cooling process effectively avoid casting defects such as trachoma, porosity and shrinkage cavity. Combined with professional heat treatment technology, the overall structural toughness, compression resistance and tensile strength of castings are greatly improved. Subsequent precision finishing, drilling, threading and surface treatment ensure that the dimensional accuracy and appearance quality of finished products meet international industrial standards.

Main Casting Process Types

1. Investment Casting (Lost Wax Casting): High-precision casting process with smooth surface and high dimensional accuracy, suitable for small and medium-sized precision castings, complex-shaped rigging parts and high-standard mechanical accessories, basically no secondary processing required.

2. Sand Casting: Suitable for large-scale, thick-wall and heavy-duty casting products, with low mold cost and strong structural adaptability, widely used in large mechanical bases, heavy-load connecting parts and engineering supporting castings.

3. Die Casting: High-efficiency die-casting forming process, fast production speed, high batch consistency, suitable for mass production of medium and small-sized standardized casting parts, with stable appearance and size.

Customizable Processing Scope

1. Heavy-Duty Rigging Castings: Custom forged-cast integrated shackles, thickened pulley blocks, heavy-load connecting bases and special-shaped lifting accessories with super load-bearing requirements.

2. Special-Shaped Mechanical Parts: Custom hollow thick-wall parts, irregular structural brackets, integrated fixing seats and complex assembly accessories that cannot be formed by stamping and cutting.

3. Large Engineering Castings: Custom mechanical equipment bases, engineering supporting parts, equipment shell castings and industrial fixing components for heavy industrial scenarios.

4. Non-Standard Integral Forming Parts: According to customer drawings and sample requirements, customize all kinds of exclusive integral casting products to solve the structural strength problems of assembled and spliced parts.

Applicable Casting Materials

Support multiple industrial-grade metal casting materials to meet different working condition requirements: Carbon Steel, Alloy Steel, Stainless Steel 304/316, Cast Iron, Ductile Iron, Aluminum Alloy and Copper Alloy. All raw materials are inspected for chemical composition and mechanical properties before production to ensure the hardness, toughness and corrosion resistance of castings meet actual application standards.

Post-Processing & Surface Treatment

Provide complete one-stop post-casting supporting processes: Deburring & Polishing, Precision Machining, Drilling & Tapping, Heat Treatment (Quenching & Tempering), Electro Galvanizing, Hot-Dip Galvanizing, Sandblasting, Painting and Anti-Rust Passivation. Effectively eliminate casting surface defects, improve product finish and anti-corrosion performance, and enhance overall assembly accuracy and service life.

Core Service Advantages

1. Integral Forming & High Structural Strength: One-time casting integral molding without welding and splicing, dense internal metal structure, strong compression resistance, impact resistance and load-bearing capacity, not easy to deform or break under heavy load.

2. Break Complex Structure Limitations: Effectively solve the customization difficulties of thick-wall, hollow, special-shaped and heavy-duty parts that cannot be realized by laser cutting, bending and CNC single-piece processing.

3. Diversified Process Matching: Flexible selection of investment casting, sand casting and die casting processes according to product size, precision requirements and order volume, balancing product quality and customer cost budget.

4. Excellent Batch Stability: Standard mold pouring and standardized process control ensure consistent size, performance and appearance of each batch of castings, with high interchangeability of finished parts.

5. Full-Customization Capability: Support exclusive mold opening, drawing customization, sample copying and performance parameter adjustment, meeting personalized non-standard casting demands of various industries.

FAQ

Q1: What is the difference between Casting Service and stamping/CNC parts?

A1: Casting is suitable for thick-wall, heavy-load and complex integral structural parts with higher overall strength and better integrity; stamping and CNC are more suitable for thin-plate, high-precision and light-duty parts. We select the most suitable process according to your product usage scenario.

Q2: Are casting parts easy to have trachoma and cracks?

A2: We adopt precise mold design and strict temperature control technology, with professional defect detection procedures. All finished castings are free of trachoma, porosity and crack defects, ensuring stable structural performance.

Q3: Can custom cast parts be processed with precision threading and drilling?

A3: Yes. We support secondary CNC precision processing on cast blanks, including drilling, tapping, chamfering and flat milling, to meet high-precision assembly requirements.

Q4: What is the MOQ for custom casting?

A4: We support small-batch trial production and large-batch mass production. For new custom molds, we provide flexible MOQ policies to meet different customer order needs.

Q5: Can casting products be customized for special anti-corrosion and high-temperature resistance?

A5: Yes. We can customize special alloy materials and match professional surface anti-corrosion, high-temperature resistant coating processes according to customer working conditions, adapting to marine, high-temperature and corrosive harsh environments.
