V-CUT scoring machines · Dongguan, China · since 2008
Chinese PCB plants have bought V-CUT equipment from Shenghai since 2008 — more than 5,000 machines in service across PCB, LED and aluminium-substrate production. They keep coming back because the groove cut in year one still matches the drawing in year ten.
Specified by leading PCB manufacturers
Measured by domestic shipments of V-CUT scoring machines, Shenghai ranks in the top three in China. For a plant outside China that means the installed base, spare-parts depth and service experience of a volume manufacturer — not a trading office assembling a handful of machines a year.
Ranked among the three largest suppliers of V-CUT scoring machines in the Chinese market.
Installed across PCB, LED and aluminium-substrate plants since 2008.
Volume production at our 20,000 m² plant in Humen, Dongguan.
Plants come back for the second and third machine, which is the only reliability metric that counts.
Market position based on the company's own shipment records for 2025. Customer names are published in our company profile and remain the property of their respective owners.
Most V-CUT suppliers assemble machines and buy tooling elsewhere. We machine both, which is why cut quality and blade life are matched to each other.
Every machine below shares the same scoring geometry and the same blade family. Choose by panel size, groove count and whether you need one axis or two.
Inline scoring with ten blades, up to 35 m/min, +-0.03 mm parallel precision.
Eight-blade inline scoring on the same 35 m/min platform, lower tooling cost.
Compact six-blade inline scorer for smaller panels and mixed batches.
Eight horizontal plus eight vertical blades. X and Y grooves in one pass, no re-fixturing.
Scores both directions at 15 m/min. Five times the handling speed of a conventional scorer.
Marble-bed gantry CNC, pin-referenced. Every groove from one setup.
Annual output is around 1,000 machines. More than 5,000 plants have bought from us since 2008. This is what that looks like.

In-house scoring and handling
Reads the actual panel edge per panel, corrects the cut position before the first groove.
Rigid FR-4, multilayer and HDI panels, straight and cross grooves in one pass.
Aluminium-backed LED strips and panels, PCD tooling protects visible faces.
Metal-core PCB for power modules and automotive lighting.
High-mix panels where changeover time decides cost per board.
Semi-automatic cells that bring V-grooving in house without a full line.
Oversized arrays on the CNC gantry range, pin-referenced.
Direct customers include listed PCB manufacturers and consumer-electronics brands. Names published in our company profile.

Equipment is only as good as the response when it stops. Direct factory contact, stock blades, and regional partners for overseas installations.
Before recommending a machine we ask what the bottleneck actually is: throughput, groove position tolerance, surface marking, or labour. The answer decides the configuration.
Double-sided panels previously needed two runs and a manual turn between them. The 16-blade turning line scores both axes in a single pass, which removed the turn, the second fixturing step and the mis-registration that came with it.
1.6 mm aluminium-backed boards were wearing carbide cutters faster than planned and leaving a burr on the visible edge. Moving to PCD tooling and vacuum top-feeding extended the change interval and removed the secondary deburring step.
A plant running six different panel families wanted one tooling standard across the shop. Standardising on the 480 platform and a single blade family meant one spare-parts stock and one set of operator procedures.
