Precision Aluminum Die‑Casting for Heavy‑Duty Machinery Components

Yongzhu Casting turns raw aluminum ingots into mission‑critical gearbox housings, hydraulic manifolds, and pump bodies for global OEMs. We have 1800‑ton and 2000‑ton presses,One rigid, leak‑tight casting lands on your line in as little as 8 weeks.

Problems YongzhuCasting Solve

Heavy‑duty equipment has no tolerance for leaks, distortion, or excess weight. Yet many OEMs still rely on cast iron, sand molds, or welded sheet‑metal boxes that fail under real‑world loads. Yongzhu’s vacuum die‑casting combines thin walls, integral ribs, and cast‑in channels—all in one hit—so you can ship lighter, stronger machines without redesigning the rest of your platform.

Cracked Weldments

Our one‑piece ribbed chassis absorbs vibration for millions of cycles.

Overweight Cast Iron

Aluminum cuts 35 % mass and slashes freight costs.

Porous Sand Castings

Vacuum + HIP delivers < 0.4 % porosity and 5 bar oil tightness.

Long Tooling Lead Times

Soft tooling delivers 50 pcs EVT parts in just 14 days.

Why Choose YongzhuCasting

Tool shops often claim speed but outsource CNC or coatings, adding hidden days. We machine inserts, EDM gates, powder‑coat, and run salt‑spray—all under one roof. That means you get design changes in days, not weeks, and a coating spec that matches exactly what left our lab.

What Our Customers Say

“Assembly time –18 minutes per unit.”
Our self‑propelled sprayer gearbox used to be seven laser‑cut plates and 42 welds. Yongzhu’s one‑piece die‑cast housing arrived fully machined; line technicians bolt the PTO and go. Annual labour savings: 820 hours.
Tier‑1 Agricultural‑Equipment Supplier
Manufacturing Engineer
“IP69K wash‑down passed on the first build.
We needed a motor shell that survives caustic foam in food plants. The hard‑anodised die‑cast body held seal compression after 1 000 h spray—zero water ingress, zero bearing rust.
Food‑Processing Conveyor OEM
Lead Designer
“Warranty returns fell from 5 % to 0.2 %."
Mining trucks blew O‑rings at 250 bar because our sand‑cast hydraulic manifolds were porous. Vacuum die‑cast blocks from Yongzhu stayed leak‑free through a 600‑bar burst test; field failures vanished.
Global Off‑Highway Hydraulics Brand
After‑Sales Director
“Noise down 4 dB, no thermal cut‑back."
The fin geometry that Yongzhu modelled in Flotherm dropped stator temps 12 °C on our 37 kW screw compressor. Customers now market it as the ‘quiet line’—and we exited 24‑hour thermal derating entirely.
Industrial Air‑Compressor Manufacturer
R&D Manager
“PPAP in six weeks, tooling budget –$1.2 M."
Wind‑turbine pitch‑motor housings were slated for five cast‑iron pieces plus machining. A single 9.5 kg die‑cast shell met our torsion spec; hard tool was qualified in week 6, saving more than a million in pattern and weld fixtures.
Utility‑Scale Wind‑Turbine OEM
Program Manager
“Inventory down 30 % with VMI."
Yongzhu stocks 4 000 lawn‑equipment pump housings and drip‑feeds us weekly. We freed 480 m² of warehouse space and cut carrying cost by a third.

FAQs for Buyers of Aluminum Die‑Cast Components in the Machinery & Equipment Sector

What wall‑thickness can Yongzhu achieve on a 6 kg gearbox housing?

We routinely cast down to 2.5 mm ribs and 3.2 mm walls on 6–8 kg gearboxes. A self‑propelled sprayer gearbox we delivered in 2024 hit 3.0 mm average and passed a 250 h vibratory test without cracking.

How leak‑tight are your hydraulic manifolds?

Vacuum die‑casting + HIP keeps internal porosity below 0.4 % (X‑ray Level B). A 2023 project for saw warranty leaks fall from 5 % (sand cast) to 0.2 % after switch‑over.

What flatness can you hold on a 450 mm pump head?

After one‑setup 5‑axis machining we certify ≤ 0.05 mm flatness across a 450 mm sealing face (CMM report supplied with every lot).

How much weight can I save versus cast iron?

Expect 30–40 % reduction. Fork‑lift OEM cut a gearbox from 7.2 kg to 4.5 kg and eliminated a lifting aid on their assembly line.

Does aluminum survive high‑cycle fatigue?

Our A380‑T6 compressor shell has cleared 2 million torsion cycles at 120 % load—matching ductile‑iron durability at 63 % of the mass.

Which alloys do you stock for high‑strength parts?

Standard: A380, ADC12, EN AC‑46000. Optional: AlSi9Cu3Fe (240 MPa yield) for gearboxes, and AlMg5 for welding compatibility.

How do you protect parts against salt‑spray?

Dual‑layer finish—chromate + 120 µm polyester powder—withstand 1 000 h ASTM B117 (marine gearbox for Wärtsilä).

Can aluminum housings reach IP69K?

Yes. A food‑grade motor shell passed 80 bar / 80 °C wash‑down after hard‑anodizing and RTV gasket.

Typical tooling lead‑time & cost?

Soft tool (P20 insert) in 14 days / ≈ US$ 7 k; hard H‑13 tool in 6 weeks / ≈ US$ 45 k for a 5 kg housing.

Tool life before re‑cut?

100 000 shots before insert refurbishment; verified by SPC drift logs on 4 gearbox programs.

What in‑process inspections are run?

Real‑time cavity pressure sensors, X‑ray sampling every 2 h, CMM report on 100 % of critical datums, helium leak test on 10 % of pump heads.

Vacuum vs. conventional die‑casting—worth the premium?

Vacuum lowers trapped air from 3 %‑vol to < 0.5 %, cutting leak scrap by 80 %. ROI is < 9 months on any part that seals oil, gas, or refrigerant.

Can you run FEA/thermal simulation before tool steel?

Absolutely. Our CFD‑coupled FEA cut fin mass 20 % on a 37 kW screw‑compressor head yet lowered T<sub>j</sub> by 12 °C.

Minimum annual volume?

Pilot lots as low as 200 pcs; economic break‑even usually 1 000 pcs/yr when amortizing a hard tool.

ESG impact—any CO₂ savings data?

Switching 8 000 cast‑iron pump housings (10 kg → 6.5 kg Al) saves 28 t CO₂/yr in freight and energy, per LCI study with TÜV SÜD.

Why partner with Yongzhu Casting instead of another die‑caster?

Only Yongzhu combines 2 000 t presses, vacuum casting, in‑house powder‑coat, salt‑spray lab, and PPAP‑ready CNC on one campus—cutting your risk, lead‑time, and supplier count. Upload a CAD file today and we’ll return a DfM + quote in 48 hours, free.

What shipping and inventory options do you offer if we don’t want stock held off‑site?

We normally ship FOB Ningbo or CIF nearest port on a per‑lot basis. Typical sea transit to Los Angeles is 19–22 days, to Rotterdam 27–30 days. For urgent gaps we arrange air‑freight “gap lots” ≤ 500 pcs that reach North America or Europe inside 6‑7 days door‑to‑door—used successfully in 2024 by a German pump OEM when demand spiked 18 %. Long‑term consignment or VMI programs can be negotiated once annual volume is clear, but we do not maintain standing inventory hubs by default.
