Die casting
Professional Die Casting Production Services
Die casting is a high-pressure metal forming process: molten metal is injected into mold cavities under high pressure and high speed, then rapidly cooled and solidified to form finished parts. It serves as the mainstream high-efficiency manufacturing technology for precision non-ferrous metal components. DotZeno provide high-efficiency die casting solutions for mass production of lightweight, complex & precision thin-wall non-ferrous metal parts with high-pressure rapid forming technology.Supported by inhouse workshop facilities, we can build and test early functional models quickly and costeffectively. This allows you to validate key concepts before committing substantial time and budget to further product development. Whether you require proofofconcept samples, engineering prototypes or preproduction samples, our prototyping services deliver tailored solutions aligned with your project goals. Backed by decadeslong industry experience, we produce accurate, practical prototypes to mitigate risks and accelerate your timetomarket.
Mold Manufacturing
Custom mass-production die casting molds available at DOTZENO. Prior to mold fabrication, our engineers conduct mold flow analysis on your parts to identify and eliminate potential quality defects in advance.This empowers our senior team to continuously refine designs based on realworld insights. The outcome is more intuitive, userfriendly products aligned with customer expectations, helping you achieve better market adoption and higher enduser satisfaction.

Common Aluminum Alloy Grades and Application Scenarios
Alloy Grade | National Standard Code | Tensile Strength (MPa) | Hardness (HB) | Core Features | Application Scenarios |
ADC12 (JIS Standard) | YL113 | 170~220 | 85~100 | High silicon content, excellent fluidity, cost-effective general-purpose grade, easy to machine, average wear resistance | Automotive housings, motor casings, home appliance shells, general structural parts, new energy small components |
A380 (ASTM Standard) | YL112 | 240~280 | 95~115 | High Cu content, superior strength, heat resistance and wear resistance compared to ADC12, excellent die casting stability | Transmission housings, engine accessories, high-strength structural parts, integrated die casting |
YL104 (A360) | YZAlSi10Mg | 220~260 | 80~95 | Contains Mg, better air tightness, higher elongation, lower porosity sensitivity | Water pump valve bodies, hydraulic housings, parts requiring slight pressure resistance |
YL101 | YZAlSi10Mg | 210~250 | 78~92 | Excellent casting fluidity, suitable for thin-walled precision parts, slight age hardenable | 3C heat dissipation brackets, thin-walled housings |
ADC10 | Similar to YL112 | 190~230 | 88~102 | Lower impurities, better surface finish than ADC12 | Appearance parts, parts requiring spraying and anodizing |
Common Zinc Alloy Grades and Application Scenarios
Alloy Grade | National Standard Code | Tensile Strength (MPa) | Elongation (%) | Hardness (HB) | Core Features | Application Scenarios |
Zamak 3 (3# Zinc) | ZnAl4Mg | 285~320 | 8~12 | 82~92 | General-purpose base grade, optimal fluidity, excellent dimensional stability, the most widely used zinc alloy | Locks, luggage buckles, instrument casings, general hardware, toy small parts |
Zamak 5 (5# Zinc) | ZnAl4Cu1Mg | 320~370 | 5~8 | 90~105 | Copper added to improve strength, hardness and wear resistance, slightly reduced toughness | Gears, bearing bushings, load-bearing hardware, bathroom hardware |
Zamak 2 | ZnAl4Cu3 | 380~420 | 2~4 | 115~130 | High strength and high hardness, poor fluidity, prone to aging | Heavy-duty wear-resistant small parts, niche applications |
