Product Description

Product Description

Zinc Alloy Die Cast Gas Block Housing – Precision Engineered for High-Performance Applications

This gas block housing is manufactured using high-pressure zinc alloy die casting combined with CNC precision machining and mirror chrome electroplating.

The result is a component that delivers exceptional dimensional accuracy, superior surface aesthetics, and reliable structural integrity — purpose-built for demanding mechanical and tactical applications.

Each piece is produced at our ISO-certified facility in Dongguan, China, where over 100 university-educated and overseas-trained engineers and technicians ensure every component meets the highest quality standards.

 
Key Features

High-Pressure Die Casting Manufactured using advanced high-pressure die casting equipment, ensuring dense internal structure, minimal porosity, and consistent dimensional repeatability across large production runs.

CNC Precision Machined Inner Bore The inner cylindrical bore is finish-machined using CNC turning centers, achieving tight tolerances (±0.02mm) for perfect fitment and smooth installation.

Mirror Chrome Electroplating A multi-layer electroplating process (copper base coat → nickel → chrome) produces a brilliant mirror finish with excellent corrosion resistance, wear resistance, and premium visual appeal.

Integrated Logo Embossing Custom brand logos or product markings can be integrated directly into the die cavity — no secondary engraving required, reducing cost while enhancing brand identity.

Anti-Slip Knurling Pattern The bottom edge features a precision wave-form knurling pattern, providing secure grip during installation and operation.

Mounting Slot & Set Screw Port Top-side rectangular mounting slot with precision-drilled set screw hole ensures secure and repeatable assembly with mating components.
