Product route
Shanhai supplies pre-grooved poplar and linden pencil slats from China, quoted by board size, groove geometry, core diameter, treatment, packing, and destination.
Product selection
For factories that need prepared grooves before lead-core assembly.
Prepare for downstream production
Send an existing specification for OEM production, or discuss an existing construction and packaging format for an ODM brief. Confirm each requirement in one written order record.
Specify wood species, board dimensions, tolerances and the process your factory will complete next.
Choose cut slats, grooved slats or core-filled sandwich boards. Confirm groove geometry and core requirements where applicable.
Agree moisture, treatment, straightness, bonding and packing checks relevant to your downstream process.
Product or reference, planned quantity and destination. Add packaging, testing and delivery requirements as the specification develops.
Confirm the product, artwork and pack. Typical sample planning is 10–15 days after the required inputs are complete; exact terms are quoted.
Agree material, process, appearance, count and packing checks. Typical production planning is 25–45 days after approvals and commercial release.

A pre-grooved slat quotation becomes comparable only when the board, groove, core-fit, conditioning, packing, and release controls are recorded against the same downstream production route.
Reviewed:
Common slat references include 184 × 71 × 5 mm or 6.3 mm. Final dimensions and tolerances are confirmed from the buyer's drawing, equipment, and approved reference sample.
Confirm groove count, geometry, spacing, core diameter, graphite or color route, and the downstream core-placement and pressing process.
Record poplar or linden, grade, moisture acceptance method, and any softening, waxing, carbonization, or other required treatment.
Approve the reference sample, packing, inspection points, batch identification, delivery term, and destination before production release.
