Your compressor scroll drawing is the starting point. We machine the part exactly to that file, then verify every critical dimension before shipment. No guesswork, no surprises.
We run a 20-year-old precision manufacturing facility in Dongguan, China. Our CNC lines handle scroll profiles, flank clearances, and sealing surfaces daily. You send the drawing. We return a part that fits your assembly on the first try.

Three Reasons Buyers Send Us Their Drawings
1. Batch-traceable quality. Every batch gets a unique job number. We record material heat numbers, tool wear data, and machine parameters. If a problem appears in your assembly, we trace it back to the exact batch and shift. This is not standard in most shops. It is standard here.
2. Inspection report per batch. You do not have to trust us blindly. Each shipment includes a CMM report with measured values for all critical dimensions. We also photograph the part against the drawing callouts. You check the numbers before you pay the balance. This removes the risk of overseas sourcing.
3. One factory for CNC, stamping, springs, and heat sinks. Your compressor assembly likely needs more than just the scroll part. We also run metal stamping presses, spring coiling machines, and heat sink fabrication lines. You send us the whole BOM. We coordinate all processes under one roof. Fewer suppliers, fewer logistics headaches, lower total cost.
Where These Parts Are Used
CNC machined compressor scroll parts go into systems that move air or refrigerant under pressure. We supply parts for:
Automotive AC compressors – scroll sets for electric and hybrid vehicle HVAC systems. Tight flank clearance is critical for efficiency.
Heat pump compressors – residential and commercial units. The scroll profile must hold its geometry under thermal cycling.
Air brake compressors – heavy truck and rail systems. Surface finish on the discharge port affects noise and wear life.
Medical oxygen concentrators – small scroll compressors running continuously. Material certs and traceability are mandatory here.
Refrigeration units – transport and stationary cold chain equipment. We machine both the fixed and orbiting scroll members.
In each case, the buyer is an engineer who needs a reliable part, not a commodity. They send us a drawing because they need a partner who can hold tight tolerances on complex 3D profiles.
Q: What is your MOQ?
A: No MOQ. We machine a single prototype for testing or a million-piece annual contract. The per-piece price drops with volume, but the quality standard stays the same.
Q: How do you guarantee tolerance and quality?
A: We use in-process probing on the machine, then verify with a CMM after machining. Every batch ships with a signed inspection report. If a dimension is out of spec, we rework or scrap it before it leaves the factory. You only pay for parts that pass.
Q: What is your lead time for a custom CNC machined part?
A: Prototype parts ship in 7 days after drawing approval. Production runs take 15 days. For urgent breakdowns, we can expedite a single piece in 48 hours at a small surcharge.
Q: Can you provide material certificates and test reports?
A: Yes. We provide EN 10204 3.1 material certificates, hardness test reports, and chemical composition analysis. For medical or aerospace applications, we add full traceability documentation at no extra cost.
