Importing an oil press from China can deliver excellent value — if you choose the right supplier. The wrong one brings delays, wrong voltage, missing spare parts and a line that never reaches its promised capacity. Use these seven checks before you order from any oil press machine supplier.

1. Is the supplier the actual manufacturer?

Ask for the factory address, a live video tour and business licence details. A manufacturer controls quality, lead time and spare parts; a middleman controls none of them.

2. Can they supply the complete process, not just one machine?

Oilseeds go through shelling, crushing, flaking, roasting, pressing, extraction and refining. A supplier who can deliver the whole chain — for example an oilseeds sheller and a batch tank extractor for small oil plants — will design stage capacities that actually match.

3. Do the specifications match your raw material?

Sunflower, peanut, rapeseed, cottonseed and palm need different pretreatment and pressing parameters. Give the supplier your exact seed, moisture and target capacity, and ask for a written process design.

4. Is the electrical configuration correct for your country?

Voltage, frequency and phase must be confirmed before production. For Africa and South Asia, confirm 380V/50Hz (or your local supply) and whether a generator-friendly configuration is needed.

5. What spare parts and consumables are included?

Wear parts, screens, filter cloth and seals should be listed with part numbers. Confirm how long shipping a replacement will take.

6. What does after-sales really cover?

Insist on installation and commissioning support, operator training manuals, and a clear response time for technical questions — ideally by video call.

7. Do they have references in your region?

Ask for projects in Africa or South Asia. Local references tell you whether the equipment survives your climate and power conditions.
