A PLC control system allows the machine to coordinate different production stages.
Zhenying's current ZY-PD08 model uses PLC control.
When comparing machines, buyers should ask which parameters can be programmed and how easily operators can adjust the production cycle.
6. Power and Voltage
Electrical requirements must match the factory's available power supply.
The current ZY-PD08 specification is:
16.5 kW / 380 V（Adjustment with transformer）
Power requirements affect installation planning, electrical infrastructure, and operating conditions.
Before purchasing, manufacturers should confirm the machine's voltage, total power, and electrical configuration with the supplier.
7. Automatic Mold Opening
Automatic mold opening is particularly important for manufacturers seeking to reduce repetitive manual handling.
The production sequence can be integrated as:
Baking → Water Cooling → Hot Pressing → Cold Pressing → Automatic Mold Opening
Zhenying's PVC Keychain Making Machine uses a patented automatic mold-opening system.
This feature should be evaluated according to the actual mold structure and product requirements rather than treated simply as a marketing feature.
8. Machine Dimensions and Factory Space
Machine dimensions affect factory layout and installation.
The current ZY-PD08 model measures approximately:
1600 × 1100 × 1470 mm
The integrated baking and molding structure is designed for a compact production setup, with approximately 1–2㎡ of installation space, depending on the layout.
However, manufacturers should also reserve space for operator access, molds, materials, inspection, and product handling.
9. Mold Compatibility
A machine cannot be evaluated separately from the mold.
Before purchasing, manufacturers should confirm:
- Mold dimensions
- Mold structure
- Number of cavities
- Product thickness
- Mold-opening method
- Heating requirements
- Cooling requirements
For 3D PVC keychains, mold design has a direct influence on product appearance and production capacity.
10. Production Capacity
Machine specifications should ultimately support the required production output.
A basic theoretical calculation is:
Hourly Output = 60 ÷ Cycle Time × Mold Cavities
For example, if a mold produces 8 keychains per cycle and the longest production step cycle takes 3 minutes:
60 ÷ 3 × 8 = 160 theoretical pieces/hour
Actual production will be lower or higher depending on the complete production setup, including material preparation, mold changes, inspection, downtime, and machine utilization.
Therefore, buyers should provide the supplier with their actual product requirements before asking for a capacity estimate.
| Specification | Why It Matters |
| Molding pressure | Must match product and mold requirements |
| Template size | Determines suitable mold dimensions |
| Heating range | Must support the required PVC process |
| Cooling method | Helps stabilize molded products |
| Control system | Coordinates production parameters |
| Power / voltage | Determines installation requirements |
| Automatic mold opening | Reduces repetitive manual handling |
| Machine dimensions | Affects factory layout |
| Mold compatibility | Determines product and cavity options |
| Cycle time | Directly affects production capacity |
How Should Manufacturers Choose?
The right PVC Keychain Making Machine is not necessarily the machine with the highest specification.
A better approach is to match the machine to five factors:
Product → Mold → Material → Production Volume → Automation Level
For example, a manufacturer producing small promotional PVC keychains may have different requirements from a factory producing large 3D PVC figures.
The machine should therefore be selected according to the complete production process.
Zhenying PVC Keychain Making Machine
Zhenying Machines manufactures equipment for PVC and silicone soft-rubber product production.
The ZY-PD08 PVC Keychain Making Machine combines PLC control, integrated baking and molding, water-circulating cooling, and automatic mold opening.
It is designed for applications including:
- 3D PVC keychains
- PVC cartoon dolls
- Soft PVC toys
- Double-sided zipper pulls
- Promotional gifts
- Customized PVC figures
For manufacturers evaluating equipment, the most important question is not simply “What are the machine specifications?”
It is:
“Which specifications match my product, mold, production volume, and automation requirements?”
That approach leads to a more practical equipment selection.
