At Yuhui Die Casting, surface finishing is more than just the final step — it’s a core part of delivering durable, functional, and visually appealing die cast products. Backed by over 27 years of experience and equipped with four independent surface treatment lines, Yuhui offers customized finishing services that enhance product performance and meet industry standards.
Before any surface finish is applied, each die cast part undergoes essential pre-treatment steps:
Deburring: Manual and automated removal of burrs, flash, and gate residues.
Reshaping/Correction: Ensures dimensional accuracy and prevents deformation.
Chemical Pre-treatment: Cleans and activates the surface to improve paint or coating adhesion.
These processes ensure a clean, defect-free surface ready for finishing.
A solvent-free, eco-friendly finish that provides excellent resistance to wear, corrosion, and UV exposure. Yuhui offers a wide selection of textures (smooth, sand, wrinkle, etc.) and full RAL/PANTONE color customization. Ideal for indoor and outdoor applications.
Spray Painting: Offers a wide range of finishes—matte, gloss, rubberized, or textured.
UV Coating: Uses ultraviolet light for rapid curing, improving surface hardness and chemical resistance. Commonly used for parts with high cosmetic requirements.
Creates a protective oxide layer that enhances corrosion resistance and surface hardness. Available in clear or colored finishes and meets RoHS compliance. Ideal for ADC12, A380, and other aluminum materials.
Applies a metal coating (e.g., chrome, nickel, zinc) to enhance appearance, corrosion resistance, and electrical conductivity. Often used in automotive and electronic applications.
Also known as Alodine or Iridite, this chemical process offers a thin-film corrosion-resistant layer. It also improves adhesion for paint or powder coatings and is suitable for aluminum, zinc, and magnesium parts.
| Feature | Description |
|---|---|
| Precision | Achieves Ra ≤ 0.8 μm surface roughness and tolerances as tight as ±0.05 mm. |
| Quality | All processes comply with ISO 9001, IATF 16949, and ISO 14001 standards. |
| Eco-Friendly | RoHS-compliant coatings, reduced VOC emissions, and high-efficiency processes. |
| Industry Expertise | Serves automotive, medical, telecom, aerospace, and consumer electronics industries. |
Yuhui also conducts coating thickness, gloss level, adhesion, and salt spray tests to ensure finish quality and long-term performance.
When selecting a surface finish for your die cast parts, consider:
Material type (e.g., aluminum vs. zinc alloy)
Functional requirements (e.g., corrosion resistance, cosmetic appeal)
Product application (e.g., outdoor exposure, precision fit)
Volume and cost
Post-processing needs (e.g., printing, assembly)
Submit drawings (2D/3D) → Free DFM review and quote
Prototype development → Approval before mass production
Surface pre-treatment → Powder coating, spray paint, UV or anodizing
Quality inspection → Functional, cosmetic, and durability testing
Packaging and delivery → Safe, on-time, and consistent shipments
