What are the advantages of die casting?

Detailed Explanation of the Core Advantages of Die Casting

1. Integrated Molding of Complex Structures

Eliminating Machining:

Directly cast threaded insert holes, thin-walled reinforcement ribs (as thin as 0.5mm), curved oil passages, and more (such as in motorcycle crankcases), eliminating drilling and milling steps.
Multi-slide core-pulling technology enables side grooves and undercut structures (such as the spring groove inside an automobile seatbelt buckle).

Unrivaled Precision:

Dimensional tolerances of ±0.05mm (equivalent to the diameter of a human hair), ensuring precise assembly clearances in one go.

2. Unparalleled Mass Production Efficiency

Sub-second Production:

Single-part molding cycle times of 10-60 seconds (up to 30 parts per minute for zinc alloy parts), with a 24/7 production capacity of 10,000 parts.
Mold lifespans exceed 100,000 cycles, reducing costs to negligible levels in mass production.

No Surface Treatment Required:

Directly achieve a Ra 1.6μm finish (such as on Apple laptop cases), eliminating the need for polishing or electroplating.

3. Material Performance Criticality

Lightweight King:

Aluminum alloy die-cast parts are 50% lighter than steel parts, with comparable strength (e.g., Tesla's battery tray is 40% lighter).

The Perfect Thermal Management:

Aluminum die-cast heat sinks are 60% lighter than copper parts, with 20% higher thermal conductivity (die-cast thin fins + vacuum degassing).

4. Cost-Crushing Tactics

Material Utilization 95%+:

Gating/scrap parts are remelted, saving 80% of material compared to CNC machining.

Labor Cost Zero:

Fully automated production lines (robotic part handling + AI quality inspection) allow a factory of 1,000 employees to employ only 10 operators.

5. Defect Control High-Tech

Porosity Elimination:

Vacuum die-casting reduces internal porosity to ≤ 0.1% (compared to ≥ 5% for conventional die-casting), meeting the sealing requirements of hydraulic components.

Strength Resurrection:

T6 heat treatment increases tensile strength by 50% (e.g., in motorcycle clutch cover modifications).

6. Cross-industry Capabilities

From micro-components to giants:

From as small as 0.1 gram zinc alloy gears (watch movements) to as large as 50 kg new energy vehicle motor housings.
