Customized zinc die casting for OEM and ODM projects are highly sought after by more project creaters. 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) and ODM (Original Design 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 Customized Zinc Die Casting ?

Customized zinc die casting is a specific manufacturing process where new customized zinc cast die is designed and manufactured firstly, then molten zinc alloy is injected into the new mold under high pressure. Because Zamak 3 and Zamak 5 is ideal for hot chamber die casting process, once the molten zinc fills the cavity, it cools rapidly and solidifies into the required shape. The shaped casting part is then ejected, trimmed, inspected, and optionally allows have special surface finishes, like painting, powder coating, vertasility plating metal coating layers.

Unlike standard off-the-shelf parts, customized zinc die casting focuses on tailor-made components created specifically for OEM brands or ODM product developers.

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.
