Zinc alloy OEM die casting solutions are becoming more challenging as global manufacturers increasingly demand more intricate, functional, and cost-efficient ultra-precision cast parts. In today’s competitive manufacturing market, die casting manufacturers need reliable production methods that combine precision, speed, durability, and cost efficiency. This is especially important for OEM (Original Equipment Manufacturer) projects, where custom die cast parts often play a critical role in final product quality and brand value.
Zinc die casting offers outstanding dimensional accuracy, excellent surface finish, fast production cycles, and the ability to create complex geometries at competitive costs. From automotive hardware and electronic housings to furniture accessories and industrial components, zinc die casting supports a wide range of customized applications.
What Is Zinc Alloy OEM Die Casting ?
Zinc alloy OEM die casting is a specialized manufacturing process where clients typically establish confidentiality agreements with the die casting manufacturer to protect proprietary designs and brand requirements. Based on the customer’s specifications, a dedicated zinc alloy die casting tool (die) is designed, developed, and manufactured to enable precise and repeatable mass production. Because Zamak 3 and Zamak 5 is ideal for hot chamber die casting process due to their good metal fluidity and ductility. At lower melting temperature achieve high effective mass production. then these net-shape parts are trimmed, inspected, and optionally allows have special surface finishes, like painting, powder coating, vertasility plating metal coating layers.
Unlike standard off-the-shelf components, zinc alloy OEM die casting focuses on producing tailor-made parts engineered specifically for global industrial manufacturers and application requirements.

Our Customized Zinc die Casting For OEM
OEM projects usually involve a customer who already owns the product design, drawings, specifications, and brand. According to their requirements, Ts die casting technology arranges reproducing identical parts consistently over large production volumes. Customer provide their 3d file and drawing or existed prototype to us, and sign the confidential argreement with us, tell us to follow their requirements strictly.
Why OEM Projecter To Choose Us ?
As an exprienced die casting manufacturer, we can save more cost, consistent quality mass prouction for zinc die casting components and brand protection.
Consistent Quality Guarantee
Ts die casting technology had been engaging for die casting process for 15 years, Once tooling is approved, through our advanced die casting machines and automation production lines, zinc die casting products can be produced by thousands or millions with repeatable quality.
Lower Unit Cost in Volume Production
Zinc die casting belongs to fast cast cycle, cast part can be formed at fast cooling condition. Low heat consumption and longer tooling life prompts more high quality cast part output. Although tooling requires upfront investment, per-part cost becomes very competitive in medium and high quantities.
Brand Protection
OEM customer requires their branded products, and always sign the confidential agreemeet with us. They tell us to follow thier requirement strictly without any disclosure for their information to thirty party, otherwise, all are involved of legal issues.
Our Customized Zinc Die Casting For ODM
ODM projects often begin with an idea, concept, or market need rather than a completed engineering drawing. Ts die casting technology can help them to design the product, optimize structure, build tooling, and produce final parts. The special project is called as “turnkey “project.
How Zinc Die Casting Supports ODM Development
From exceptional 3D product design and engineering development to mold flow simulation analysis, our team continuously improves and optimizes the die casting mold structure until the final precision mold drawing is completed. After manufacturing high-precision steel tooling for mass production, rapid prototype trial casting is conducted to verify dimensions, surface quality, and assembly performance. Finally, stable large-volume mass production is achieved with consistent precision and manufacturing efficiency.
Product Design & Mold Manufacturing Assistance
Ts die casting technology employed well-skilled engineering team and sophisticated molde technicians, which design and manufacture precision durable steel cast die. Our professional engineering teams can help improve:
- Wall thickness balance
- Draft angle design
- Rib structure strength
- Assembly features
- Surface appearance
- Cost reduction opportunities
- Venting and gating system modify
- Design parting line on the cast part
- Balance Die thermal and allow uniform cooling, minimizing common defects, like cold shut, shrinkage and crack and warp.
Zinc Cast Die Process Typical Tolerance
Precision zinc die casting provides excellent dimensional accuracy and stable repeatability for complex metal components. Typical Zinc Die Casting Tolerance Range is beneficial from advanced CNC flat grinding machine, world class cnc machining equipment, high precision Wire cutting machine and EDM equipment.
| Dimension Range | Typical Tolerance |
|---|---|
| 0–25 mm | ±0.02 mm |
| 25–50 mm | ±0.03 mm |
| 50–100 mm | ±0.05 mm |
| Over 100 mm | ±0.08 mm or according to structure |
Rapid Prototype Support
Before mass production, ODM customers often need prototypes for testing and marketing review. we provide the below rapid prototyping services:
- CNC prototypes
- 3D printed samples
- Die casting parts
Fast Transition to Mass Production
Zinc die casting offers fast cast cycle due to Zamak 3 or Zamak 5 is formed intended cast parts at lower temperature. and create consistent qualifed cast parts with superior surface finish repeatedly at mass production.
Vertasility Surface Finishings For Cast Parts
Depends on the requirements of surface roughness of cast part surface polished, the below surface finishings are allowed after the cast part polishing processing
- Color Painting
- Powder coating
- Chrome-plating
- Satin-Nickel Plating
- Gloss-Nickel Plating
- Electrophoresis
- PVD coating
Zinc Alloys Commonly Used in Customized Projects
Whenever Zamak, ZA or other special zinc alloys, all follows the requirement of customer and project party. Several zinc alloys are popular in OEM and ODM manufacturing.
Zamak Serial
| Type | Feature | Application |
|---|---|---|
| Zamak 3 | excellent balance of strength, castability, and cost. | Hardware, consumer products and electrics |
| Zamak 5 | Higher strength and hardness than Zamak 3 | Mechanical parts, Automotive fittings and Structural components |
ZA Serial
| Type | Feature | Application |
|---|---|---|
| ZA-8 | 8.5% aluminum content, Good ductility and can use hot chamber die casting | Structural brackets, Industrial mechanical parts |
| ZA-12 | 11% aluminum content, higher Tensile Strength than ZA-8, high hardness, good wear resistance | Stronger than most die-cast aluminum alloys. |
| ZA-27 | 27% aluminum content, high hardness, excellent wear resistance | Suitable for structural & load-bearing parts. |
