2. Key Product and Service Features

Progressive Die Stamping and Precision Metal Forming

Progressive die stamping is suitable for producing repeated metal components through sequential operations within a stamping die. Depending on part geometry and production requirements, available processes include blanking, punching, bending, and forming.

For parts requiring greater depth or complex shapes, deep drawing and related forming processes can also be evaluated. The appropriate tooling and production method depend on material properties, thickness, dimensional tolerances, and annual demand.

Full OEM and ODM Customization

Hehua Machinery Technology (Kunshan) Co., Ltd. provides integrated manufacturing support for customized metal parts, including:

• Product and mold design

• Design for Manufacturability (DFM) review

• Prototype and sample production

• Progressive die and other stamping processes

• CNC machining

• Welding and assembly-related processing

• Surface treatment and finishing

• Batch production and export packaging

This integrated approach helps buyers coordinate multiple manufacturing processes through one supplier and evaluate potential cost or process improvements before production.

Broad Material Selection

The service supports a range of metals for different strength, corrosion-resistance, conductivity, and forming requirements.

Available material options include:

• Carbon steel

• Cold-rolled steel

• Galvanized steel

• Stainless steel 304 and 316

• Aluminum

• Copper

• Special drawing steel

Material selection should be based on the component's mechanical requirements, forming complexity, operating environment, and applicable industry standards. Material certificates and traceability documentation can be discussed during the quotation process.

Precision Manufacturing and Dimensional Inspection

The stated stamping tolerance range is ±0.008 mm to ±0.03 mm, depending on part geometry, material, and process conditions. The service also lists a flatness target of ≤0.02 mm and a deep-drawing wall-thickness deviation of ≤5% for applicable parts.

Inspection support includes coordinate measuring machine (CMM) inspection, checks of key dimensions, and inspection reports. These precision figures are application-dependent targets rather than universal guarantees for every stamped component. Confirm achievable tolerances against the actual drawings and measurement requirements before placing an order.

In-House Tooling and Production Equipment

The manufacturing setup includes 63T–315T precision presses, automatic stamping lines, and an in-house mold workshop. These resources support tooling development and production planning for both trial quantities and larger recurring orders.

The suitable press, die structure, and production sequence are determined by the part's dimensions, material thickness, forming force, and required production volume.

Integrated Surface Finishing

Surface treatment options can be coordinated according to the part's material and intended use. Available services may include:

• Deburring and as-machined finishing

• Sandblasting

• Anodizing, where suitable for the selected material

• Polishing and mirror polishing

• Powder coating and painting

• Laser engraving for logos or text

Not every treatment is applicable to every material or stamped part. Final finishing requirements should be confirmed during engineering review.

3. Technical Capabilities and Specifications

Important: Tolerances, sample schedules, production lead times, and certification scope should be confirmed for the specific part and order. The listed figures are capability references and may vary according to design complexity, tooling requirements, material availability, and inspection criteria.

4. Custom Part Development Process

Step 1: Submit Drawings or Samples

Provide 2D engineering drawings, 3D files in STEP or IGS format, SolidWorks models, or physical samples. Include material grade, thickness, critical dimensions, surface requirements, annual demand, and applicable industry standards whenever available.

Step 2: Engineering and DFM Review

The engineering team reviews the part structure, forming feasibility, tolerance requirements, and tooling approach. Where appropriate, the review may identify opportunities to simplify production, reduce material waste, or improve manufacturability.

Step 3: Tooling and Sample Production

After the manufacturing plan is confirmed, tooling development and sample production can proceed. A pre-production sample is recommended so that dimensional accuracy, material, surface finish, and fit can be reviewed before batch production.

Step 4: Sample Approval and Production

Once the sample is approved, the production plan can be finalized for the agreed quantity. Tooling condition, process parameters, and inspection checkpoints should be established according to the component's quality requirements.

Step 5: Inspection and Delivery

Finished parts undergo the agreed inspection procedures. Reports, packaging specifications, and delivery arrangements can be confirmed before shipment.

5. Typical Applications

The Progressive Die Stamping service supports custom metal components for a range of industrial applications.

• Compressor accessories: Stamped brackets, shims, covers, and other components designed to customer drawings.

• Pneumatic equipment: Metal fittings, brackets, and precision components for pneumatic systems.

• Construction machinery: Formed metal hardware and structural support parts.

• Industrial machinery: Custom sheet-metal components used in equipment assemblies.

Final suitability depends on the design, material, operating conditions, and qualification requirements of the target industry.

6. Quality Control and Production Management

Consistent dimensions and material quality are important for components used in equipment assemblies. Hehua's stated quality-control capabilities include material traceability, CMM inspection, key-dimension checks, and inspection reporting.

For projects requiring close dimensional control, the inspection plan can be defined around the drawing, including critical-to-quality dimensions, flatness, forming characteristics, and other acceptance criteria. Material documentation and traceability requirements should be agreed upon before production.

The company reports ISO 9001, IATF 16949, and EN 15085 certifications. Buyers should request current certificates and confirm their validity, applicable facilities, processes, and product scope when certification is a purchasing requirement.
