Toilet seat covers remain in strong global demand for hotel projects, residential bathrooms and public sanitary‑ware markets. Manufacturers pursuing large‑volume output increasingly adopt 600‑ton double‑layer molding machines because they deliver double‑station forming under consistent high pressure.
However, improper operation frequently triggers typical pain points: bubbled parts, surface deformation, inconsistent quality between upper‑layer and lower‑layer outputs, low daily capacity and shortened machine service life.
Leveraging advanced Taiwanese technology and extensive manufacturing experience in melamine molding machines, Shunhao Factory offers comprehensive one-stop services and technical support to toilet seat cover machinery importers. In this article, Shunhao will deliver complete, parameter references, step by step operating procedures, and maintenance guidance.

The 600‑ton double‑layer toilet seat lid compression machine adopts dual‑station synchronous hydraulic pressing. Two toilet‑seat blanks can be molded within one production cycle under rated 600‑ton clamping force. Stable pressure distribution guarantees high‑density, low‑deformation melamine toilet‑seat covers.

Step by Step Standard Operation Guide
1. Power on Self Inspection & Mold Preheating
Switch on power and air supply. Allow machine to finish self-diagnosis. Set target mold temperature. Wait until both double layer mold zones reach stable target temperature before feeding. Temperature inconsistency between two layers will directly cause uneven product quality.
2. Production Parameter Calibration
Set core running parameters: 600-ton molding pressure, pressure holding duration, heating time and cooling duration. Adjust synchronization parameters for dual stations to keep upper layer and lower layer actions aligned. Configure automatic feeding and ejection parameters based on toilet seat cover thickness and size.
3. Quantitative Feeding
Feed precise raw material weight for each mold cavity respectively. Avoid over feeding causing flash overflow or insufficient feeding leading to incomplete product shape. Ensure even raw material distribution inside both cavities.
4. 600-Ton High Pressure Synchronous Molding & Pressure Holding
Activate automatic production cycle. Hydraulic system builds up stable 600-ton clamping force. Both layers complete compression simultaneously. Maintain required pressure holding time to guarantee full cross link curing of melamine compound.
5. Circulating Cooling & Automatic Demolding
After pressure holding phase completes, start circulating water-cooling procedure. Sufficient cooling prevents finished part warping. Once cooling countdown finishes, molds open automatically and finished toilet seat covers eject out.
6. Initial Product Inspection & Cyclic Production
Take out finished pieces and run quick visual check for bubbles, deformation or incomplete edges. If first sample meets quality standard, the machine can enter continuous cyclic production. Clean mold surface residues after every cycle to avoid surface scratches on subsequent products.

FAQ
Q1: Is double‑layer molding suitable for customized toilet seat cover production?
A1: Yes. It supports custom‑shaped toilet seat covers as long as matched double‑layer molds are installed. Note that both mold cavities need identical geometry to guarantee synchronization performance.
Q2: Do you have CE for the machines?
A2: Yes, CE certification is available.
Q3: How to send an inquiry to you?
A3: You can contact us by Email: machine@hongancn.com.
