How to Make a Plexiglass Display Case
Creating your own plexiglass display case is a rewarding project that combines creativity with practicality. Whether you’re showcasing collectibles or enhancing retail presentations, this guide will walk you through the process from design to assembly.
Designing Your Plexiglass Display Case
The first step in creating a plexiglass display case is designing it according to your specific needs. Consider the following factors:
-
Purpose: Determine what you’ll be displaying. Light items like model cars can be showcased with a 3mm thick plexiglass sheet, while heavier items like pottery or figurines require a thicker sheet of 5 or 6mm.
-
Dimensions: Measure the space where the display case will be placed. Ensure there’s enough room for the case and easy access.
-
Style: Decide on the overall look and feel. Modern, minimalist designs are popular, but you can customize the style to match your decor.
Gathering Materials and Tools
Once you have your design ready, gather the necessary materials and tools:
-
Plexiglass Sheets: Purchase high-quality plexiglass sheets from a reputable supplier. Ensure they’re cut to your specified dimensions.
-
Adhesive: Use plexiglass-safe glue or cement for bonding the sheets together.
-
Sandpaper: Get various grits for smoothing edges.
-
Polishing Tools: Include a polishing wheel or microfiber cloth for achieving a glossy finish.
-
Clamps: Necessary for holding pieces in place while the adhesive cures.
-
Protective Film: Keep this on during fabrication to prevent scratches.
Cutting and Preparing the Plexiglass Sheets
Precision is key when cutting plexiglass sheets. Use a laser cutter or CNC machine for accurate cuts. If you’re working manually, a fine-toothed saw can be used, but exercise extreme caution to avoid chipping or cracking the material.
After cutting, remove any burrs or rough edges by sanding with progressively finer grits, starting from 220-grit up to 800-grit. This ensures a smooth surface for the next steps.
Assembling the Display Case
Step 1: Joining the Back and Side Walls
Begin by attaching the back wall to one of the side walls. Remove the protective film from the edges to be glued, and sand the top side of the back wall with 400-grit sandpaper to promote adhesion.
Apply a thin line of plexiglass cement along the edge of the back wall using a syringe or applicator bottle. Carefully align the side wall and press it against the back wall, ensuring a perfect right angle. Use clamps and masking tape to hold the pieces in place while the adhesive cures.
Step 2: Adding Supports
Once the initial bond between the back and side walls has cured, it’s time to add supports. Mark the positions on the side and back walls using a soft pencil. Sand the edges of the supports that will be glued.
Apply adhesive to each support and position them inside the display case. Use clamps and tape to secure them during drying. Ensure the supports are straight and do not protrude from the sides.
Step 3: Attaching the Remaining Walls
Following the same process, attach the remaining side wall and front wall to the assembly. Double-check all angles for squareness and make any necessary adjustments before allowing the adhesive to cure completely.
Polishing the Edges
For a professional finish, polish the edges of your display case. Use a polishing wheel with an acrylic-safe compound for a glassy, crystal-clear finish. Alternatively, use a microfiber cloth and polishing solution for smaller pieces or final touch-ups.
Remember to keep the material cool during this process to prevent cloudiness or damage. Cover the edges with painter’s tape after polishing to protect them from scratches during the final assembly.
Adding Optional Features
Enhance the functionality of your display case by adding optional features:
-
Hinges or Locks: Install these for easy access and security. Choose hardware that matches your display case’s style and can support its weight.
-
Base or Footplate: Consider adding a base for stability, especially if the display case will be placed on carpeting.
Conclusion
Creating your own plexiglass display case is a rewarding project that combines creativity with practicality. By following these steps and paying attention to detail, you can craft a beautiful and durable display case that perfectly showcases your prized possessions. Remember to handle the plexiglass sheets with care to maintain their clarity and finish.
Common Questions About Making Plexiglass Display Cases
1. How do I prevent the edges from turning white during polishing?
To avoid cloudy edges, work at a steady pace and keep the material cool. Take breaks when the plexiglass feels warm to the touch, and ensure you’re using an acrylic-safe polishing compound.
2. What type of adhesive is best for plexiglass display cases?
Plexiglass cement is ideal as it creates a clear, strong bond. It’s specifically formulated for plexiglass materials and provides a professional finish when applied correctly.
3. How can I ensure the display case is structurally sound?
Use thicker plexiglass sheets for larger or heavier display cases. Add reinforcements like internal supports, especially for cases wider than 50 centimeters, to prevent deflection.
4. What safety precautions should I take when working with plexiglass?
Always wear protective gloves when handling plexiglass cement, as it can cause skin irritation. Work in a well-ventilated area and use clamps to secure pieces during assembly to avoid accidental movement.
5. How do I clean the plexiglass sheets before assembly?
Wipe the sheets with a mixture of soap and water to remove any dust or debris. This ensures better adhesion of the adhesive and a cleaner finish overall.
