Baffle Boards Flat Board Blanks

These flat acoustic baffle board blanks are used inside injection-mold tooling and nearby process enclosures where sound and vibration must be reduced. In industrial automation and conveyor housings, flat baffle stock helps absorb sound waves generated by rapid actuation, improving operator comfort without reshaping the mold structure.

In medical device housing molds and other precision assemblies, board blanks can be integrated into vented sound-control features around tooling areas to limit airborne noise during cycling. The flat blank format supports predictable acoustic performance because it can be cut or fitted to a baffle location while maintaining an even plate thickness.

For electronics and connector manufacturing cells where brass or aluminum corrosion resistance matters, selecting the appropriate alloy variant helps maintain long-term stability in humid or coolant-adjacent environments. Use the available width (A = 6–35 mm) and length options (L = 50–300 mm) to match the required baffle envelope and assembly layout.

This product is supplied as a flat blank in either Aluminum or Brass, selected for corrosion-ready durability in typical mold-room conditions. Both variants are provided as blank acoustic baffle stock intended to absorb sound waves rather than act as wear parts.

• Aluminum: lower mass for easier handling and integration; favorable for applications where weight and vibration coupling are considerations.
• Brass: offers strong corrosion resistance and mechanical stability for environments with higher exposure to moisture or residues.

Heat treatment and hardness are not specified in the provided data, and therefore cannot be confirmed for these blanks. For projects requiring hard, wear-resistant surfaces, verify the supplier’s alloy and any post-processing (e.g., annealed condition, temper, or machining allowances) before use.

To select the correct dimensions, start from the baffle assembly envelope in your mold tooling or surrounding enclosure. The product provides variable width A (6–35 mm) and discrete length options L (50, 100, 150, 200, 250, 300 mm).

Match A to the available side-to-side spacing in the baffle mounting area, then choose L to cover the targeted sound-absorbing span. If your design uses multiple baffles, select dimensions so adjacent pieces avoid gaps that can reduce acoustic effectiveness.

• Fit/tolerance: since tolerances are not provided, plan for machining, trimming, or fitting allowances as required by your baffle holder design.
• Configurable vs. fixed: A is variable within 6–35 mm, while L is offered in fixed standard lengths.

Confirm clearance with fixtures, fasteners, and any nearby moving components to prevent contact during cycle motion or thermal expansion.
