Question 1

Are you a real manufacturer or trading company?

Accepted Answer

We are a professional electrical manufacturer with independent R&D, production and export team. We supply products for well-known brands and support OEM & ODM.

Question 2

Can I arrange a factory visit?

Accepted Answer

Sure. We warmly welcome clients to visit our production workshop, testing lab and warehouse. Arrangement and reception service are available.

Question 3

What materials do you offer for hydraulic oil tanks?

Accepted Answer

We manufacture in carbon steel (Q235/Q355) and aluminum alloy (5052/5083). Carbon steel tanks undergo pickling & phosphating before powder coating for maximum corrosion resistance. We can recommend the best material based on your operating environment.

Question 4

Can you fully customize the design to my specifications?

Accepted Answer

Absolutely. We are an OEM/ODM specialist. Just send your drawings or 3D files, and we will match every dimension, port location, baffle layout, and mounting bracket to your exact requirements. 10L to 500L capacity range.

Question 5

How do you guarantee zero leakage?

Accepted Answer

We run two separate airtight pressure tests on every single tank: first on all weld seams, second after all ports and accessories are assembled. Combined with single-pass robotic welding (9 seams reduced to just 3) ,our field replacement rate is<= 0.3% on dump trucks and 0% on all other vehicle types.

Question 6

What is the coating process and how long does it last?

Accepted Answer

We apply electrostatic powder coating with a two-layer spec: 0.06-0.08 mm internally (oil-contact surface) and 0.04-0.06 mm externally. Adhesion reaches grade 1-0. We back it with a 3-year coating warranty , and real-world service life reaches 8-10 years with zero fading or peeling.

Question 7

What is your MOQ and lead time?

Accepted Answer

1 unit for sample orders. For mass production, typical MOQ starts from 50 units. Sample lead time: 7-10 days. Bulk order lead time: 15-25 days depending on order volume and customization complexity. Our 14-robot automated line ensures consistent output without delays.

Question 8

Can I get a sample for quality evaluation?

Accepted Answer

Yes, samples are available. We encourage you to inspect our weld quality, coating finish, material thickness, and internal cleanliness before placing a bulk order. Just share your specification, and we will prepare a sample tank for your approval. The sample fee and shipping fee shall be borne by the buyer.

Question 9

How do you ensure tank cleanliness and prevent internal contamination?

Accepted Answer

We developed a proprietary internal treatment process in 2016 that completely eliminates the long-standing industry problem of residual debris and contamination inside the tank. The process passes destructive testing - 90 bend and open-flame tests-with zero defects. Your hydraulic system stays clean from day one.

Question 10

How is the tank packaged for export shipping?

Accepted Answer

Every tank is packed with foam corner protectors, clear stretch wrap, and black tension straps on a fumigated ISPM 15 wooden pallet. An outer corrugated kraft carton provides an additional protective layer. We can also customize packaging-plywood crates, steel frames, or your branded packaging-upon request.
