Mechanical & Industrial Fabrication — Nationwide

When does a business need outsourced mechanical fabrication

Businesses typically outsource fabrication when order volume exceeds in-house shop capacity, when they need 3-5 axis CNC machines they don't own, or when producing a small batch of 10-50 parts makes buying dedicated equipment inefficient. For example, a small machine shop receiving an order for 200 stainless steel 304 parts needing CNC milling within 2 weeks can avoid buying a 3-axis milling machine costing 500-800 million VND just for that one order. For structural steel welding on factory buildings, construction companies also often hire welders with 6G certification instead of hiring permanent staff.

How to choose a fabrication provider

For CNC turning and milling, ask about achievable tolerance (±0.01mm or ±0.05mm) and whether the machine is 3-axis or 5-axis, since this directly affects price and part accuracy. For structural steel welding, require welders certified to AWS or TCVN 6700 standards if the project needs formal acceptance testing. For electroplating and powder coating, ask about coating thickness in micrometers, since this determines corrosion resistance - not just the visible color. Request a sample piece before signing a large-volume order.

The ordering process on vServe

Customers send technical drawings (CAD files, PDFs with dimensions and tolerances) along with quantity and preferred material, and providers on vServe quote per order rather than using a fixed price list, since each part differs in fabrication complexity. Quote response time is usually 60-240 minutes depending on the service. Once both sides agree on price and delivery time, the order is confirmed through vServe, and the customer inspects the finished parts either at the provider's workshop or at the job site, depending on the service type (at_provider or at_customer).

Industrial equipment certification standards in Vietnam

Industrial boilers in Vietnam must undergo periodic inspection under Technical Regulation QCVN 01:2008/BLDTBXH, usually every 1-2 years depending on type and capacity, performed by a licensed inspection body. Compressed air systems and pressure vessels also fall under strict occupational safety requirements. vServe does not replace the role of a licensed certification body - providers on vServe perform technical maintenance, while legal inspection records must be handled directly with an inspection organization designated by the Ministry of Labor, Invalids and Social Affairs.

Choosing the right surface treatment for your environment

Hot-dip galvanizing suits outdoor steel structures, withstanding humid and corrosive environments for 15-20 years, commonly used for power poles and prefabricated steel frames. Powder coating suits indoor parts, offers more color options but lower corrosion resistance than galvanizing, and is common for electrical cabinets and shelving. Chrome/nickel plating is typically used for machine parts needing gloss and wear resistance, such as shafts and gears. Sandblasting is a mandatory surface preparation step before painting or plating to improve coating adhesion.

Notes on scheduling industrial equipment maintenance

Industrial pump maintenance should be done every 3-6 months to catch early wear in seals and bearings before it causes unexpected production line downtime. Heat exchanger descaling should be scheduled when heat transfer efficiency drops noticeably, usually shown by outlet temperature falling short or pressure rising unexpectedly. Industrial well drilling for production use requires a groundwater extraction permit from local authorities before construction begins; businesses should prepare this paperwork alongside booking the drilling service.
