Frequently Asked Questions
Answers to common questions about cooling components, custom parts, precision and ordering.
- Are you a manufacturer or a trading company?
- We are a manufacturer. Dongguan Tianying Mold Fitting Limited runs its own production facility with in-house CNC machining in Dongguan, Guangdong, China. Your enquiry goes directly to the people who make the parts.
- Can you make parts from our own drawings or samples?
- Yes. Custom manufacturing from customer drawings or physical samples is our main business. Send us a drawing (STEP, IGES, DWG or PDF) or a sample part and our engineers will review feasibility and the machining plan with you.
- What types of components do you produce?
- Cooling system components — quick couplings, water nipples, coupling sockets, sealing plugs, manifolds, air valves and hose clamps, plus custom mold accessories. German-, American-, French- and Japanese-style connections are product groupings; the exact series, dimensions, thread and operating conditions must be confirmed. Standard parts are stocked and custom parts can be made to order; availability and lead times for specific items require confirmation.
- What machining precision can you hold?
- We work to tolerances of ±0.01mm on imported CNC equipment. The achievable tolerance for a specific part depends on its geometry, material and surface requirements, so we confirm it against your drawing before quoting.
- Do you hold any quality certifications?
- Yes. Our quality management system is ISO 9001 certified, and we can provide the certificate and inspection documentation on request.
- How do I get a quote?
- Send your drawing or sample details through the inquiry form, or email us directly. We provide individual quotes instead of publishing fixed prices — a quote depends on material, tolerance, quantity and finish. Telling us the quantity and material up front lets us respond faster.
- Which languages can your team communicate in?
- We handle enquiries in Chinese and English. This website is also available in Japanese, Korean and Spanish.
