Q: What products do you manufacture?

A: We produce stainless steel couplings, hose fittings, and custom metal components. Main categories include Bauer coupling, Perrot coupling, Guillemin coupling, Camlock coupling, Storz coupling, KC nipples, hose menders, strainers, clamps, and precision-cast parts.

Q: Do you offer OEM and customized parts?

A: Yes. We accept drawings, samples, or technical specifications. We design molds, cast the parts, machine them, and provide final inspection. Non-standard sizes, threads, and materials are supported.

Q: What materials do you use?

A: Common materials include stainless steel 304, 316, CF8, CF8M, and custom alloys. Carbon steel and mild steel are available for specific products. All materials are tested with a spectrometer to confirm chemical composition.

Q: What is your casting process?

A: We use the silica-sol investment casting process. This method offers stable dimensions, smooth surfaces, and strong corrosion resistance. It is suitable for precision couplings and industrial hardware.

Q: What machining operations can you perform?

A: Our machining workshop handles turning, milling, drilling, tapping, threading, surface finishing, and custom machining. We support BSP, BSPT, NPT, DIN, and customer-specified threads.

Q: What are your tolerances?

A: Casting tolerances follow CT5–CT7 standards. Machined tolerances follow customer drawings. Sealing faces, threads, and critical dimensions receive 100% inspection when required.

Q: Can you provide samples?

A: Yes. Standard samples are available. Custom samples require mold fees. Samples are inspected before shipment, and reports are provided upon request.

Q: Do you provide material certificates or inspection reports?

A: Yes. We can provide 3.1 material certificates, spectrometer reports, dimensional inspection reports, and pressure test reports if needed.

Q: What surface finishes are available?

A: We offer sandblasting, polishing, passivation, anti-rust treatment, and custom finishing based on customer requirements.

Q: Do you perform pressure or leak tests?

A: Yes. Pressure testing is available for couplings and fittings that require sealing performance. Test pressure can follow customer or industry standards.

Q: What packaging do you use?

A: We use protective bags, custom labels, carton boxes, and wooden pallets for export. Packaging can be customized to meet project or distributor requirements.

Q: What payment terms do you accept?

A: Common terms include T/T, 30% deposit and 70% before shipment. Other terms can be discussed based on long-term cooperation.

Q: Do you support third-party inspections?

A: Yes. Customers may use SGS, TUV, BV, or their appointed inspection agency. We cooperate fully with external audits.
