Description

Membrane Box 38.6 x 38.6 x 18.3 mm

Membrane-supported component protection

Product Overview

This membrane box is made with upper and lower high-clarity PS shells and transparent high-elastic membrane films. The outer size is 38.6 x 38.6 x 18.3 mm, and the usable inner size is 32 x 32 x 11 mm, making it suitable for compact components that need protected suspended positioning inside a clear package.

It is designed for fragile, polished or irregular precision parts that should not be tightly clamped or placed against hard support surfaces. In storage, sample transfer, inspection and display preparation, the membrane structure helps reduce surface rubbing, edge impact and part displacement while keeping the component visible without unpacking.

Key Features and Advantages

  • Suspended membrane holding helps protect finished or sensitive surfaces from direct hard-contact support.
  • The packed component remains visible through the clear shell, which improves identification, inspection and presentation efficiency.
  • The structure is suitable for irregular or easily displaced small parts that require centered positioning during storage and transfer.
  • Compared with direct-contact packaging, this format helps reduce shifting and local impact during routine handling and packing preparation.
APPLICATION SCOPE: Optical parts, crystal samples, dental prosthetics, watches, jewelry, miniature assemblies and other small delicate precision components that require stable suspended positioning during inspection, transfer and presentation.
PACKAGING: Store in a clean, dry area away from dust, heat and sharp objects that may damage the membrane surface. Before closing the box, confirm that the component outline fits the usable inner size of 32 x 32 x 11 mm and does not create excessive local pressure on the membrane.
IMPORTANT NOTICE: The standard version of this membrane box is non-latch. Optional latch closure is available on request. If the component has sharp edges, high point-load concentration or electrostatic sensitivity, please confirm the suitable shell material and closure configuration before ordering.

Store in a clean, dry area away from dust, heat, and sharp objects to prevent membrane damage. Confirm component dimensions fit the usable inner size and avoid excessive local pressure on the membrane.

  • Storage Environment: Store the membrane box in a clean, dry area away from dust, heat, and sharp objects that may damage the membrane surface.
  • Fit Verification: Before closing, confirm that the component outline fits the usable inner size of 32 x 32 x 11 mm and does not create excessive local pressure on the membrane.
  • Sharp Edge Caution: Components with sharp edges or high point-load concentration may require alternative shell material or closure configuration.
  • Electrostatic Sensitivity: For electrostatic-sensitive components, confirm suitable shell material and closure configuration before ordering.
  • Closure Type: The standard version is non-latch; optional latch closure is available on request.

Open the two-piece shell and inspect the transparent membrane for any damage or debris. Place the component gently onto the lower membrane, ensuring it is centered and does not exceed the inner dimensions.

Required Equipment: Membrane box

  1. Inspect Membrane
    Inspect the membrane surfaces for any damage, debris, or contamination before use.
  2. Confirm Component Fit
    Confirm that the component outline fits within the usable inner size of 32 x 32 x 11 mm.
  3. Place Component
    Place the component gently onto the lower membrane, ensuring it is centered and does not create excessive local pressure.
  4. Close Shell
    Close the upper shell evenly, verifying that the component remains suspended without shifting or contacting the hard shell.
  5. Store Box
    Store the closed membrane box in a clean, dry area away from dust, heat, and sharp objects.

What is the maximum allowable point-load pressure on the membrane film before distortion or rupture occurs for components stored in this 38.6×38.6×18.3mm membrane box?

The source does not specify a maximum point-load pressure threshold. The membrane is described as a high-elastic transparent film designed for gentle non-clamping retention, and the product warning states that if the component has sharp edges or high point-load concentration, the suitable shell material and closure configuration must be confirmed before ordering. For parts with concentrated mass or sharp protrusions, the recommended practice is to evaluate fit within the usable inner size of 32x32x11 mm and avoid excessive local pressure on the membrane.

Can this membrane box accommodate components with irregular geometries greater than 11 mm in height, such as watch crowns or dental prosthetics with tall profiles?

No, components must fit within the usable inner size of 32x32x11 mm. The membrane box is designed for compact parts; any component exceeding 11 mm in height risks distorting the membrane or preventing proper closure. The recommended component list includes watches, jewelry, and dental prosthetics, but only if the overall dimensions respect the inner cavity limits. For taller profiles, a different box model would be required.

What storage and handling precautions are required to prevent electrostatic discharge damage to sensitive components placed in the standard non-anti-static membrane box?

The standard configuration uses high-clarity PS shells and transparent high-elastic membrane films with no inherent anti-static properties. The source advises storing the box in a clean, dry area away from dust, heat, and sharp objects, and notes that if the component has electrostatic sensitivity, the suitable shell material must be confirmed before ordering. An optional anti-static shell material is available upon request. For ESD-sensitive parts, use the anti-static option and handle in an ESD-safe environment.

This membrane box provides suspended protection for delicate optical and precision components, but its standard non-latch closure and fragile membrane surface require careful handling and optional upgrades for sharp or electrostatic-sensitive items.

Positive

  • Suspended membrane protection: The membrane holds components without hard clamping, reducing surface rubbing and edge impact for fragile or polished parts.
  • Visible inspection without unpacking: The clear shell allows visual identification and inspection of the component without opening the box, improving workflow efficiency.

Trade-offs

  • Standard non-latch closure: The standard version lacks a latch, which may allow unintended opening during handling; optional latch closure must be requested separately.
  • Membrane surface susceptibility to damage: The membrane can be damaged by sharp edges, high point loads, or electrostatic sensitivity, requiring careful selection of shell material and closure type.
