Material Preparation and Bamboo Processing

Goal: Select high-quality bamboo, cut it into appropriate strips, and prepare them for bonding.

• Bamboo Selection: Choose bamboo that is 4-5 years old for its density and durability. Since bamboo’s natural diameter is limited, split it into smaller strips.
• Cutting Bamboo Strips: Cut the bamboo into strips with a thickness of 3-5mm, lengths of 20-30cm, and widths of 2-4cm. These will be bonded later to form a larger board.
• Drying the Bamboo: Dry the bamboo strips either naturally or in an industrial kiln to reduce moisture, preventing cracks or deformation during later processing.

Bamboo Strip Bonding

Goal: Bond multiple bamboo strips into a single, larger bamboo board with a thickness of 1cm.

• Bonding Bamboo Strips: Use adhesive and a press machine to bond the bamboo strips into a large bamboo sheet, with a thickness slightly exceeding 1cm for further sanding.
• Pressing and Drying: Press the bonded bamboo strips for 2-4 hours to ensure solid bonding, leaving the final board with a thickness of around 1.2cm.
• Surface Refinement: Sand the bamboo sheet to ensure smoothness, removing any excess glue marks for an even surface.

Cutting and Shaping the Circular Soap Dish

Goal: Cut the bonded bamboo board into a circular shape with a diameter of 8cm and a thickness of 1cm.

• Cutting the Bamboo Board: Using a laser cutter or CNC machine, cut the bamboo board into a circular disc with a diameter of 8cm and an initial thickness of around 1.2cm to allow for sanding.
• Edge Smoothing: Sand the edges of the circular disc to ensure precision and smoothness, eliminating any sharp or rough edges.

Drainage Design and Engraving

Goal: Create drainage holes in the bottom of the soap dish to allow water to drain easily.

• Designing Drainage Holes: Design evenly spaced drainage holes with a diameter between 0.5cm to 1cm. These can be round or slotted, depending on design preferences.
• CNC Engraving: Use a CNC engraving machine to carve out the drainage holes accurately, ensuring clean edges and precision.
• Hand Finishing: After engraving, manually sand each hole’s edges to remove any splinters, ensuring smoothness and safety.

Forming and Pressing

Goal: Slightly bend the soap dish edges to create a shallow dish shape.

• Steam Softening: Place the bamboo disc in a steam chamber to soften its fibers, making it easier to shape.
• Mold Pressing: Once softened, place the bamboo disc in a mold and use a press machine to shape the edges into a gentle inward curve. This ensures the soap stays in place and provides structure to the dish.
• Cooling and Shaping: Allow the bamboo to cool within the mold to retain its curved shape. After cooling, the final thickness will remain at 1cm.

Sanding and Polishing

Goal: Smoothen and polish the bamboo surface to enhance both texture and visual appeal.

• Initial Sanding: Use mechanical sanding tools to smooth the entire surface of the soap dish, particularly around the edges and drainage holes. After sanding, the thickness should be exactly 1cm.
• Hand Sanding: Use fine-grain sandpaper for manual finishing, focusing on intricate areas like the drainage holes and curved edges.
• Polishing: Use a polishing machine to bring out the natural luster of the bamboo, making the soap dish visually appealing and enhancing durability.

Surface Coating and Waterproofing

Goal: Apply a waterproof coating to the bamboo soap dish to protect it in wet environments.

• Waterproof Coating: Bamboo is vulnerable to water damage, so apply a layer of eco-friendly waterproof coating, such as natural oil or water-based lacquer. This not only protects the bamboo but also enhances its natural grain.
• Drying the Coating: After applying the waterproof coating, place the soap dish in a drying chamber to allow the coating to set and harden. This process typically takes 12-24 hours depending on the environment.

---

Quality Control and Eco-Friendly Packaging

Goal: Ensure the final product meets quality standards before packaging in sustainable materials.

• Quality Inspection: Each soap dish undergoes a thorough quality check for precise dimensions, smoothness, drainage efficiency, and waterproof coating consistency. Only defect-free products are sent to packaging.
• Eco-Friendly Packaging: The finished soap dish is packed using sustainable, biodegradable materials such as recycled cardboard or kraft paper. Instructions for care and usage can also be included.
