Why Choose Our Zinc Die Casting Services

80T–1500T Die Casting Equipment

Supports projects from small precision components to large structural parts.

Integrated Manufacturing Process

In-house tooling, die casting, machining, finishing, and assembly for better quality and lead-time control.

ISO 9001 & IATF 16949 Quality Systems

Production managed under internationally recognized quality standards.

Engineering-Led Project Support

DFM review, mold optimization, and manufacturing guidance before mass production.

Technical & Process Advantages

Ultra-Tight Tolerances: Achieves repeatable tolerances up to ±0.02 mm, reducing or eliminating secondary machining.

Thin-Wall Capability: Casts wall thicknesses as low as 0.5 mm while maintaining structural strength and lightweight design.

Long Tool Life: Low melting temperature (380–420°C) reduces thermal stress on molds and extends tooling lifespan.

Excellent EMI Shielding & Conductivity: Provides strong EMI/RFI shielding with high thermal and electrical conductivity, making it ideal for electronic housings.

Material Grades & Mechanical Comparison

We utilize only 100% virgin, high-purity zinc ingots accompanied by traceable material certificates.

Quick Selection Guide: Zamak 3 is the standard for 80% of electronic & cosmetic parts. Choose Zamak 5 if your components require higher tensile strength and creep resistance.

Alloy Grade	Chemical Composition & Key Attributes	Tensile Strength	Hardness	Primary Industrial Applications
(Standard)			(Brinell)
Zamak 3	The industry standard for zinc casting. Offers the optimum combination of physical/mechanical properties, excellent castability, and superb plating/finishing characteristics.	~283 MPa	82	Electronic housings, automotive components, locksmith hardware, domestic appliances.
(ASTM AG40A)
Zamak 5	Infused with approximately 1% copper. This addition significantly enhances tensile strength, hardness, and creep resistance, though with a minor reduction in ductility.	~328 MPa	91	Heavy-duty mechanical parts, functional gears, structural mounting brackets, high-load fasteners.
(ASTM AC41A)
ZA-8	Contains a higher aluminum content than the Zamak series. Ideal for hot-chamber casting applications demanding elevated structural strength and superior creep performance.	~374 MPa	103	Structural load-bearing joints, industrial connectors, heavy machinery hardware.
(ASTM Zinc-Aluminum)

Manufacturing Capabilities

80T–1500T Die Casting Machines

Supports precision zinc parts from a few grams to several kilograms.

In-House Tooling

CNC machining, EDM, and wire cutting ensure fast mold development, maintenance, and modifications.

High-Volume Production

Automated manufacturing delivers millions of parts monthly with stable quality and on-time delivery.

Production Flow & Quality Control Protocols

Coordinate Measuring Machines (CMM): For precise 3D dimensional validation against your native CAD files.

Spectrometric Material Analysis: Conducted on incoming raw material lots to verify pure chemical composition and prevent the utilization of scrap metal.

X-Ray Defect Detection: Utilized to monitor internal structural density and eliminate sub-surface porosity before parts exit production.

ISO 9001 & IATF 16949 Certified: Our quality management systems ensure full traceability and process stability, meeting strict automotive and industrial supply chain audits.

Comprehensive Surface Finishing Options

Electroplating: Chrome, nickel, zinc, or copper finishes for enhanced corrosion resistance, wear protection, and premium appearance.

Powder Coating & Painting: Available in custom RAL colors with durable protection against impact, UV, and outdoor exposure.

E-Coating: Provides uniform corrosion-resistant coverage, even on complex shapes and internal cavities.

Passivation & Chromating: Improves corrosion resistance and creates an ideal surface for painting or standalone protection.

Customization & Engineering Capabilities

We do not just cast metal; We engineer solutions. We specialize in 100% OEM/ODM customization based on your proprietary technical drawings (STEP, IGES, DWG formats).

Early Stage Involvement (ESI): Our engineering team collaborates with your R&D department to perform Design for Manufacturing (DFM) evaluations and advanced Moldflow Simulation Analysis. This optimizes gate placements, establishes uniform wall thickness, and designs out stress concentration areas prior to steel cutting.

Prototype Verification: We offer rapid prototyping solutions, including CNC machining from solid zinc blocks or prototype soft-tooling, allowing you to validate fit, form, and function before committing to production tool investments.

FAQ

Q: How fast can I get a quotation and DFM report for my custom parts?

A: Simply submit your 3D CAD files via our secure contact channel. Our engineering team will review your files and provide a detailed quotation alongside a preliminary DFM evaluation within 24 to 48 hours.

Q: Which engineering file formats do you accept for review?

A: We accept all industry-standard formats, including STEP, IGES, X_T, DWG, DXF, and PDF. Your intellectual property is completely secure with us; we are fully prepared to sign a Non-Disclosure Agreement (NDA) before you share any drawings.

Q: Do you provide secondary CNC machining after the die casting process?

A: Yes. While our zinc die casting achieves excellent near-net shapes, we operate a fully equipped, in-house CNC machining shop to handle high-precision secondary operations such as threading, reaming, tapping, boring, and ultra-precise milling.

Q: How do you guarantee that there is no scrap metal used in production?

A: Every incoming batch of zinc ingots is subjected to Spectrometric Material Analysis in our lab. We provide official material mill certificates and chemical composition analysis reports with every shipment to guarantee 100% virgin alloy usage.

Q: What are your payment and shipping terms for international B2B clients?

A: We offer flexible shipping terms including FOB, CIF, DDU, and DDP. Tooling costs typically follow a 50% deposit / 50% upon sample approval structure, with mass production payment terms customizable based on order volume and background credit checks.
