Choosing your material
What must be specified for an MDF acoustic-panel substrate?
The supplied substrate follows the geometry, finish and mounting interfaces of the complete acoustic system.
Begin with the system drawing and applicable performance test reports. Identify the exact substrate, thickness, perforation or groove pattern, finish, backing, absorber, cavity and mounting arrangement. Keep changes to those layers with the system designer's assessment and the corresponding drawing revision.
Complete system build-up
Connect the panel to its face finish, backing or fabric, absorber, cavity depth, frame, fixings, module joints and perimeter conditions.
First article and report match
Measure a representative machined and finished panel, inspect blocked openings and breakout, then map the accepted construction to the applicable report.

Selected panel and system drawing example
Connect the measured sample to its layer arrangement.
This drawing exercise selects a 600 × 1200 × 12 mm panel, 406 Ø8 mm through-holes at 40 mm pitch, a 1 mm backing and a 50 mm cavity measured from backing rear to rigid wall. A selected 25 mm absorber occupies the wall-side half of that cavity. These are nominal drawing inputs; actual material, pattern, finishes, distances, supports and performance follow the specified system and applicable report.
| Drawing item | Selected inputs or calculation | What to record |
|---|---|---|
| Selected finite hole field | 600 × 1200 × 12 mm panel; Ø8 mm through-holes at 40 mm centre pitch | Drawing face uses lower-left D0. Centres: X = 40 + 40i, i = 0…13; Y = 40 + 40j, j = 0…28; 14 × 29 = 406 holes |
| Solid face margins and webs | 40 − 4 = 36 mm; 600 − 560 − 4 = 36 mm; 1200 − 1160 − 4 = 36 mm; 40 − 8 = 32 mm | Selected 36 mm solid margins surround the full pattern; 32 mm nominal material remains between adjacent hole edges. Actual fixing zones and tolerances follow the component drawing |
| Whole-panel and cell open area | 406 × π × 4² / (600 × 1200) × 100 ≈ 2.83%; π × 4² / 40² × 100 ≈ 3.14% | The first uses all 406 holes and the gross panel area, including borders; the second uses one fully patterned repeat cell. State the chosen denominator and inspect actual clear openings after finishing/backing |
| Alternative rounded-slot exercise | 8 × (80 − 8) + π × 4² ≈ 626.27 mm² | One selected capsule slot has 80 mm overall length, 8 mm width and two R4 semicircular ends. This separate geometry exercise defines area; actual slot count, spacing and whole-panel open area follow its drawing |
| Alternative groove section | 12 − 4 = 8 mm nominal core below the deepest groove | Assumed 12 mm core and 4 mm depth illustrate retained section. The actual groove/through-opening path, remaining ribs, facing, support and mounting stay on the complete section |
| Selected layer depth | 12 + 1 + 50 = 63 mm; 50 − 25 = 25 mm | Selected 12 mm panel, 1 mm backing and 50 mm from backing rear to wall. A 25 mm absorber occupies the wall-side half of that cavity, leaving 25 mm air space between backing and absorber |
Hole centres end at X = 560 mm and Y = 1160 mm, leaving the selected 36 mm face margins around the complete finite field. A service opening, extra fixing zone or changed border changes the actual opening count and area. Recalculate that panel and retain its separate drawing and sample reference.

View productBuyer questions
Common MDF acoustic-panel substrate questions.
Plan the geometry, supplied work, complete construction and sample/report correspondence for your order.
Is perforated MDF automatically an acoustic panel?
Perforated, slotted and grooved MDF forms a machined substrate within an acoustic system. The complete assembly establishes acoustic performance: opening geometry, finish, backing, absorber, cavity, supports, joints and installation all matter. Specify the panel against the applicable system design and test report, including any required fire classification.
What determines the acoustic performance of an MDF panel system?
The relevant variables can include the hole, slot or groove geometry, open area, panel and finish construction, backing material, absorber, cavity depth, framing, mounting, module joints and installation conditions. Use a report or qualified system design that applies to the proposed complete assembly.
What drawings are needed for perforated or grooved MDF?
Provide panel dimensions, thickness, units and revision; pattern origin, pitch and first/last position; opening or groove section; unmachined borders; module joints; fixing and service zones; face direction; backing and cavity references; and part quantities.
Can the finish change the acoustic result?
Review the actual face, clear openings and backing interface after the selected finishing and attachment process. Record the coating/facing, adhesive coverage and finished dimensions with the sample. Keep changes from the specified specimen with the system designer's assessment and corresponding drawing revision.
How should machined acoustic-panel substrates be inspected?
Check panel dimensions, pattern position, opening size, pitch, blocked openings, breakout, remaining ribs, groove depth, face direction, module joints, finish inside openings, backing attachment, part labels and protected flat packing.
What should an acoustic-panel MDF RFQ include?
Send the system specification and applicable reports, module/front/back/section drawings, actual core/final thickness, finite hole/slot pattern, supplied finish, backing/absorber references, cavity measurement planes, mounting, joints/services, quantities, tolerances, sample-bay plan, sequenced packing, required documents and destination.
Can I request samples for this application?
Yes. Our product samples are free and usually available from stock. Tell us which board and finish you want to compare, including the opening pattern, remaining ribs and chosen face finish. You pay the courier charge, which can be credited against the formal order amount. We confirm sample availability, preparation and estimated transit time before dispatch.
How do I get a quotation from CUZI MDF?
Send the component or panel schedule, drawings, finish reference, quantities and destination. We reply to inquiries within 12 hours and clarify any open details with you. Your formal quotation includes specifications, supplied condition, quantity, price and currency, packaging, FOB Qingdao or FOB Lianyungang, lead time, T/T or L/C payment terms and validity. Normal production lead time is 3–10 days after technical and commercial confirmation; the quotation confirms your order schedule.
What acoustic-panel work can CUZI MDF supply?
Our factory supplies the specified substrate, cut modules and agreed through-holes, slots or grooves, with the named face and finish stage. Record ordered backing, fittings, trims and included assembly work separately in the quotation. The project's system drawing and applicable report connect those supplied parts to the absorber, cavity, support and installed performance.
Why can whole-panel open area differ from the repeat-cell value?
A repeat cell describes the regular patterned field; the gross panel includes solid borders and other unmachined zones. The selected 600 × 1200 mm example has 406 Ø8 holes at 40 mm pitch, giving approximately 2.83% across the gross panel, while one fully patterned 40 × 40 mm cell gives about 3.14%. State the denominator and actual clear openings for the order.
How should cavity depth and absorber thickness be recorded?
Name the two measurement planes and draw the absorber within the defined space. The selected section uses 12 mm panel, 1 mm backing and 50 mm from backing rear to rigid wall, totalling 63 mm. Its 25 mm absorber lies inside that 50 mm cavity, leaving 25 mm air space. Actual layers, finishes, support and distances follow the system drawing and report.
How do I match a sample with the acoustic system report?
Use one identified sample bay and record its product, pattern, supplied finish, backing, absorber, cavity measurement, frame, mounting, joints and perimeter. Connect photographs, measured geometry, drawing revision and material IDs to the relevant report's specimen and test method. Keep requested changes with the system designer's documented assessment before repeating the construction.
