Product Introduction

The aluminum alloy inverter housing is made of 6063-T6 aluminum alloy profile, with a one-piece base structure formed by a customized extrusion die, and is precisely carved by a five-axis CNC machining center. It is specially designed for photovoltaic/energy storage inverters. It integrates the structural integrity of the extrusion process with the CNC micron-level tolerance control to achieve a three-in-one solution of IP66 protection, efficient heat dissipation, and electromagnetic shielding. It is suitable for new energy scenarios such as household energy storage, industrial and commercial photovoltaics.

Product Details

Excellent weather resistance and surface treatment:

Aluminum alloy substrate is naturally corrosion-resistant, and the surface can be anodized (commonly used natural color, black, other colors), sandblasted oxidation, sprayed, etc.

The surface treatment is not only beautiful, but also greatly enhances the wear resistance, corrosion resistance, and UV resistance, extending the service life of the shell.

Flexible customization capability (core advantage of extrusion + CNC):

Extrusion die development: Extrusion dies with specific cross-sectional shapes can be developed according to demand to meet the needs of different sizes and internal structures (such as reinforcing ribs), and achieve cost-effective optimization from small batch to large batch production.

CNC programming flexibility: CNC processing has extremely high flexibility. By modifying the program, it can quickly adapt to the production of customized shells with different sizes, opening layouts, and interface requirements, responding to the diverse needs of customers.

FAQ

Q: What is the difference between extrusion and die casting of aluminum alloy shells? Which one is more suitable?

A: Extrusion is suitable for producing profiles with constant cross-sectional shape and long length. It has the characteristics of high structural strength, good material density, excellent surface quality, and relatively low mold cost (especially when the cross-section is simple), which is very suitable for box-type structures.

Die casting is more suitable for mass production of complex three-dimensional shapes and thin-walled parts, but there may be pores and the strength is slightly inferior to extrusion parts (same material).

For signal box shells that require high structural strength, good heat dissipation teeth, and high protection sealing surfaces, extrusion molding combined with CNC finishing is usually the better choice.

Q: How to control extrusion deformation of large-size shells?

A: Triple process closed loop

Gradient quenching technology: online temperature control grain refinement

Stress aging: 72 hours constant temperature shaping

Multi-point positioning milling: CNC sequence release of internal stress

Q: Mold development cycle and cost?

A: Intelligent mold system

Cycle: 12-18 days (complex section)

Cost: ￥2000-60,000 (depending on the complexity of the section)

Life: 300,000 meters↑ (mold steel 1.2344)
