Aluminum Pressure Die Casting Parts
High-Pressure Die Cast Aluminum Components for High-Volume Electrical and Industrial Production
Cable Glands India manufactures Aluminum Pressure Die Casting Parts using high-pressure die casting (HPDC) machines that inject molten aluminum into hardened steel dies at high velocity and pressure, producing thin-walled, high-precision components suited to high-volume production. Supplied at US$ 8.50/kilogram CIF/FOB Indian port in ADC12, A380 and A413 aluminum die casting alloys, these parts serve electrical OEMs, automotive component manufacturers, EPC contractors and industrial equipment builders requiring thousands to hundreds of thousands of identical parts per year.
Product Overview
High-pressure die casting forces molten aluminum into a hardened tool steel die cavity at pressures typically between 10 and 175 MPa, filling thin sections in a fraction of a second and enabling production cycle times of seconds per part, making it the process of choice for high-volume components with thin walls, fine surface detail and complex geometry achievable through multi-slide tooling. Cable Glands India operates cold-chamber HPDC machines for aluminum casting production.
Compared to gravity die casting, pressure die casting achieves thinner minimum wall sections (down to 1mm-1.5mm), tighter as-cast tolerances, and superior surface finish suitable for direct powder coating or anodizing without extensive post-machining, at the cost of higher tooling investment and generally higher as-cast porosity that limits suitability for pressure-tight or heat-treated applications compared to gravity casting.
Typical aluminum pressure die cast parts supplied by Cable Glands India include electrical enclosure housings and covers, cable gland body blanks, motor and gearbox housings, heat sink bodies with integral cooling fins, decorative and functional automotive trim components, and high-volume structural brackets where the part geometry, wall thickness and surface finish requirements are well matched to the HPDC process capability.
ADC12 (equivalent to A380) is the most widely used aluminum die casting alloy, offering a good balance of castability, strength and pressure tightness for general engineering components; A413 (near-eutectic Al-Si12) offers superior fluidity for very thin-walled parts; and A380 remains the North American standard reference alloy for general purpose die castings. Cable Glands India selects the alloy according to wall thickness, surface finish and mechanical property requirements of each project.
Because standard HPDC castings entrap a small percentage of air/gas porosity during the high-velocity fill, they are generally not heat treated (heat treatment can cause blistering from trapped gas) and are used in as-cast or lightly machined condition; where pressure tightness or higher strength is required, Cable Glands India offers vacuum-assisted die casting or squeeze casting process options to reduce porosity for critical applications.
Post-casting services include trimming and deflashing, CNC machining of precision features, shot blasting, powder coating, anodizing (Type II and Type III), impregnation sealing for pressure-tight housings, and 100% or sample leak testing for enclosures requiring IP-rated ingress protection.

- Priced at US$ 8.50/kilogram, tooling cost quoted separately per project
- Suitable for enclosures, housings, brackets and high-volume production components
High-Volume Production Capability
Cold-chamber HPDC machines achieve cycle times of seconds per shot, making pressure die casting the most economical process for annual volumes in the tens of thousands to hundreds of thousands of identical parts, once the higher upfront hardened-steel tooling cost is amortized across the production run.
Thin Wall and Fine Detail Capability
The high injection velocity and pressure of HPDC allows filling of thin sections and fine surface detail, including textured logos, ribs and bosses, that would not fill reliably in gravity die casting, enabling lighter-weight part designs with equivalent structural performance.
Aluminum Die Casting Alloy Selection
ADC12/A380 provides the best all-round balance of castability, strength and cost for general enclosures and brackets; A413 offers superior fluidity for very thin-walled or intricate parts; alloy selection is confirmed with the customer based on wall thickness, mechanical load and finishing requirements.
Porosity Management and Pressure Tightness
Standard HPDC parts contain a controlled level of gas porosity inherent to the process; for pressure-tight or IP-rated enclosures, Cable Glands India offers vacuum die casting and post-cast impregnation sealing to close residual micro-porosity and achieve reliable leak-test pass rates.
Surface Finish and Coating Options
As-cast HPDC surface finish is generally suitable for direct powder coating; shot blasting improves surface uniformity prior to coating, and anodizing (Type II decorative/protective or Type III hardcoat) is available for parts requiring enhanced wear or corrosion resistance.
Tooling and Production Support
Cable Glands India supports full tooling development from customer 3D CAD models, including design-for-manufacturability feedback on draft angles, wall thickness uniformity and gate/runner placement, first-article inspection, and ongoing production quality control through the life of the tooling.

It is a casting process where molten aluminum is injected into a hardened steel die under high pressure, producing thin-walled, high-precision parts suited to high-volume production.
What aluminum alloys are used?
ADC12, A380 and A413 are the standard alloys, selected according to wall thickness, fluidity and finishing requirements.
Can pressure die cast parts be heat treated?
Standard HPDC parts are generally not heat treated due to trapped gas porosity; vacuum-assisted die casting is available where heat treatment or pressure tightness is required.

Pressure die casting is economical for high-volume production, typically from several thousand pieces per year upward, depending on tooling amortization.
What is the price of aluminum pressure die cast parts?
Standard pricing is US$ 8.50/kilogram CIF/FOB Indian port; tooling cost is quoted separately per project.
Can you develop tooling from our 3D CAD model?
Yes, Cable Glands India provides tool design review, manufacturability feedback and hardened steel die development based on customer CAD data.
What post-casting finishing is available?
Shot blasting, CNC machining, powder coating, anodizing (Type II/III) and impregnation sealing are all available.
Are pressure die cast parts leak tested?
Leak testing is available for IP-rated or pressure-tight enclosures, using air decay or water immersion methods as specified.
What is the difference between pressure and gravity die casting?
Pressure die casting injects molten metal at high velocity for thinner walls and higher production rates, while gravity die casting relies on gravity fill for thicker sections and better mechanical properties, including heat treatability.
