If you are sourcing a compressor housing for industrial air compressors, turbochargers, or refrigeration systems, your top concerns likely revolve around dimensional accuracy, pressure integrity, lead time, and total cost. At Hebei Yuanda Trade Co., Ltd. (YD), we supply precision-cast compressor housing components in cast iron, aluminum, and stainless steel — via sand casting, die casting, or lost wax casting — with ISO 9001 quality management, MOQ as low as 50 pieces, and typical delivery of 15–25 working days. This page details exactly how we meet those requirements.
Common Procurement Challenges in Compressor Housing Sourcing
Import managers and brand owners consistently report three pain points when buying compressor housings from overseas suppliers:
- Inconsistent dimensional tolerances — housing misalignment leads to vibration, noise, and premature bearing failure.
- Long lead times — typical foundry quotes of 35–50 days disrupt production planning for wholesalers and OEMs.
- Hidden costs — mold modification fees, rework charges, and logistics surcharges inflate the total landed cost.
YD addresses these through a structured casting engineering review before production, flexible process selection (sand, die, or investment casting), and a fixed-price quotation model that includes mold amortization. Over the past 18 years, we have delivered more than 2,000 compressor housing designs to customers in North America, Europe, and Southeast Asia.
Why YD Compressor Housings Deliver Consistent Quality
Every compressor housing we produce undergoes a three-stage quality gate: raw material certification, in-process dimensional inspection (CMM), and final pressure testing. Below is a summary of our standard capabilities:
| Parameter | Capability | Notes |
|---|---|---|
| Materials | Gray iron (GG25), ductile iron (GGG40/50), aluminum A356, SS304/316 | Full chemical report with each batch |
| Processes | Sand casting, die casting, lost wax investment casting | Process selected based on geometry & volume |
| Weight range | 0.5 kg – 120 kg | Heavier weights require pattern approval |
| Tolerance | CT9–CT11 (sand), CT6–CT8 (die/investment) | Per ISO 8062 |
| Pressure testing | Up to 20 bar (hydrostatic / pneumatic) | Custom pressure on request |
| Certifications | ISO 9001:2015, CE, RoHS | Third-party inspection welcome |
| MOQ | 50 pcs (new design), 20 pcs (repeat order) | Lower MOQ possible for samples |
| Lead time | 15–25 working days (after pattern approval) | Air freight available for urgent orders |

OEM/ODM Design Support for Compressor Housing
We understand that many brand owners and sourcing agents need a housing that fits an existing compressor platform or matches a legacy part number. YD's engineering team (8 full-time CAD/CAM designers) can work from:
- 3D solid models (STEP, IGES, SolidWorks)
- 2D engineering drawings with GD&T
- Physical sample parts (reverse engineering within 5 days)
- Sketches or reference photos with critical dimensions
We provide DFM (Design for Manufacturability) feedback at the quotation stage — identifying potential shrink, draft angle, or wall thickness issues before tooling is cut. This approach has helped our clients reduce post-casting machining time by an average of 18%.
Compressor Housing Applications We Serve
Our castings are used across multiple compressor categories. The table below outlines typical applications and the preferred casting process for each:
| Compressor Type | Typical Material | Preferred Process | Volume Range (pcs/yr) |
|---|---|---|---|
| Reciprocating air compressor | Gray iron GG25 | Sand casting | 200 – 5,000 |
| Rotary screw compressor | Ductile iron GGG40 | Sand casting | 100 – 3,000 |
| Turbocharger / centrifugal | Aluminum A356 | Die casting / investment | 500 – 10,000 |
| Refrigeration compressor | SS304 / ductile iron | Investment casting | 100 – 2,000 |
| High-pressure booster | SS316 / duplex | Investment casting | 50 – 800 |
* Volume estimates are indicative. Contact YD for a feasibility review of your specific application.

- T/T (30% deposit, 70% against B/L copy) or L/C at sight
- Sea freight typically 22–28 days to US West Coast, 32–38 days to East Coast
- Packaging: Plywood crates with foam lining, or custom packaging per buyer spec
What Our Customers Say About YD Compressor Housings
"We switched to YD for our compressor housing after struggling with tolerances from two previous suppliers. The first batch of 300 ductile iron housings had zero rejects. Their DFM feedback improved our wall thickness distribution, which reduced machining time by 12%. We are now in our third year of partnership."
— Mark Thompson, Senior Procurement Manager, CompAir USA (Texas)
"As a small brand owner, I was worried about MOQ. YD accepted 50 pieces for my first aluminum compressor housing order. The surface finish was consistent, and the pressure test held at 15 bar without any leakage. Lead time was 18 working days — exactly as quoted."
— Carlos Rivera, Owner, Rivera Air Systems (Florida)
"We source compressor housings for refrigeration units. YD provided SS316 investment castings with full material traceability. The logistics team coordinated the sea freight to New Jersey smoothly. I appreciate the clear communication throughout the order."
— Lisa Chen, Sourcing Agent, RefCo Global (California)
"I visited YD's foundry in 2024. The 5,000 m² facility is well organized, and their QC lab has a CMM, spectrometer, and tensile tester. They know compressor housing inside and out. I trust their process."
— James Henderson, Wholesale Distributor, Henderson Industrial (Ohio)
"YD has been our casting partner for 6 years. Their pricing is competitive, but more importantly, they deliver on time. For our high-volume compressor housing line, they maintain a 96% on-time delivery rate. That matters to our production schedule."
— Andrew Park, VP Supply Chain, NorComp Inc. (Illinois)
