4. Common Materials Used for Plastic Cases with Card Holder Slots

The performance, durability, and cost of a plastic case with card holder slots depend strongly on the plastic material used.

Below is a comparison of common materials.

For cases that include card holder slots, the same base material is usually used for both the shell and the slot frame to simplify injection molding.

Transparent or translucent inserts may be added to protect paper cards while keeping text and barcodes visible.

5. Manufacturing Methods for Plastic Cases with Card Holder Slots

Plastic cases with integrated card slots are typically produced using the following manufacturing processes:

5.1 Injection Molding

Injection molding is the dominant process for rigid plastic cases.

The shell, hinges, latches, and card holder slots can be formed in a single mold, or as multiple components that are assembled later.

• High production efficiency for medium to large batch quantities.
• Complex geometries such as snap‑fit card frames and recessed slots are possible.
• Consistent quality and repeatability across production runs.

5.2 Vacuum Forming and Thermoforming

For larger cases and lower tooling costs, vacuum forming or thermoforming may be used.

Card holder slots are then added through separate parts or by welding/fastening transparent pockets to the shell.

• Suitable for larger, lighter‑duty cases and trays.
• Good for sample cases and display trays with card labels.
• Lower tooling cost than multi‑cavity injection molds.

5.3 Extrusion and Fabrication

Some long or modular cases and card rails are produced via extraction and then cut, welded, or assembled into cases.

Card holder slots can be created by punching, CNC machining, or integrating extruded profiles as separate components.

5.4 Additive Manufacturing (3D Printing)

For prototypes or highly customized, low‑volume designs, 3D printing can be used to create plastic cases with card holder slots.

This provides maximum design freedom but is usually more expensive per unit than mass production methods.

6. Standard Sizes and Specifications

Plastic cases with card holder slots follow common size conventions based on card sizes and overall case dimensions.

The tables below provide typical specifications used by many manufacturers and buyers.

6.1 Common Card Sizes for Card Holder Slots
