The children’s training potty is a crucial tool that helps children transition from diapers to independent toilet use. Its production involves precise plastic shaping techniques, strict material control, and multiple detailed assembly steps, all aimed at ensuring the product’s safety, durability, and comfort.
Below is a detailed overview of the main production flow for children’s shaping plastic potty trainers:
The selection of shaping plastic is vital for producing a high-quality children’s potty. Materials like eco-friendly PP (Polypropylene) or PE (Polyethylene) are typically used.
Material Selection: The chosen plastic granules must be non-toxic, odorless, high-strength, impact-resistant, and easy to clean.
Coloring and Mixing: The plastic granules are accurately mixed with color masterbatches that meet safety standards, matching the product’s design color. The materials are then pre-processed in drying equipment to remove moisture, preventing bubbles or structural defects during the subsequent molding process.
The main structural components of the potty (such as the base, seat ring, and main container) are usually manufactured using the Injection Molding process to ensure dimensional accuracy and a smooth surface finish.
Mold Preparation: High-precision steel molds are installed onto the injection molding machine. The mold cavity is the negative shape of the final product and must be preheated and kept clean.
Melting and Plasticization: The plastic granules are fed into the heating barrel of the injection machine’s screw. Through heating and the shearing action of the screw, the granules are melted into a uniform liquid state.
High-Pressure Injection: The hot, liquid plastic is rapidly injected into the mold cavity under high pressure. Pressure and speed must be precisely controlled to ensure the plastic completely fills every corner of the mold.
Holding Pressure and Solidification (Curing): After injection, the machine maintains pressure for a period (holding pressure) to ensure uniform part density and prevent shrinkage deformation until the plastic begins to cool and solidify inside the mold.
The formed parts require processing before moving to the next assembly stage.
Cooling: Cooling channels inside the mold circulate cold water to cool the part quickly and evenly, ensuring it retains its final shape.
Demolding: Once the part is fully solidified, the mold opens, and an ejector mechanism pushes the formed plastic component out of the mold.
Trimming (Deflashing): Injection molded parts often have residual flash or burrs. Workers use specialized tools or automated equipment for precise trimming and polishing to ensure all edges are rounded and smooth, complying with child safety standards.
In addition to the main plastic components, other functional parts of the potty are produced and assembled separately.
Soft Cushion Production: If the product includes a soft seat cushion made of PU or EVA material, it is produced through foaming or hot-pressing and subjected to anti-bacterial treatment.
Functional Component Integration: Small parts like anti-slip pads (TPE material), handles, and the removable inner basin are installed. These parts are typically secured to the main body using snaps, ultrasonic welding, or screws.
Drainage and Cleaning Systems: For potties with water storage or self-cleaning functions (like the one in the initial context), electronic components such as water pumps, drain pipes, or sensors must be installed, and their waterproof integrity confirmed.
This stage is critical for ensuring the product meets safety standards and customer expectations.
Safety Testing:
Load-Bearing Test: The potty structure is checked to ensure it can withstand standard pressure (usually several times a child’s weight).
Stability Test: Anti-slip performance and anti-tip stability are verified.
Material Safety Inspection: Products are randomly sampled to confirm they are free of harmful heavy metals like lead and cadmium.
Functionality Test: All movable parts (like the lid and inner basin) are checked for smooth operation, and any electronic features (e.g., pump, music) are verified for proper function.
Appearance Inspection: Products are checked for color variations, scratches, deformation, or injection molding defects.
Final Packaging: Qualified products are cleaned, packed into boxes with the instruction manual and accessories list, and sealed using sturdy packaging materials (such as corrugated cardboard boxes) to prevent damage during shipping.
By following this rigorous production flow, manufacturers ensure that the children’s training potty delivered to consumers is safe, reliable, and meets the intended design specifications.
