Chocolate Molding Machine
NGOSD16SV-ML is a semi-automatic chocolate molding machine built around a mold conveyor. On a single conveyor line, it combines a mold loader, mold heater, chocolate depositor, and mold vibration to prepare filled molds for cooling.
This format is selected when you want a stable, repeatable depositing process but prefer manual demolding and manual mold return instead of a full mold looping system. Prefilled molds can be transferred to a cooling tunnel, while demolding and feeding empty molds back to the loader remain operator tasks.

NGOSD16SV-ML chocolate molding machine - technical features
Options and integration
This machine is commonly installed as part of a forming section. Depending on your product and layout, it can be integrated with a cooling tunnel and upstream chocolate preparation equipment.

Description for the semi-automatic chocolate molding machine
Production output depends on shot weight, product viscosity, depositor timing, and conveyor speed. In typical operation, the system can perform up to 20 shots per minute (process dependent). Capacity may vary within 200–500 kg/h depending on product and settings.
If the cooling tunnel is horizontal, a rod or modular belt style is preferred so the product can be cooled more evenly from top and bottom. The chocolate cooling tunnel is commonly coupled perpendicular to the polycarbonate mold flow of the molding machine.
Center-filled focus: This configuration is designed for center-filled (fat-based) molded chocolate manufacturing. For one-shot depositing, particulate inclusions are typically not recommended; if inclusions are required, please consult for alternative configurations.
How the semi-automatic molding machine works
The line is designed as a practical workflow for stable depositing and controlled mold handling:
- Molds are fed to the conveyor by the mold loader.
- Molds pass through the mold heater to stabilize mold conditions before depositing.
- The depositor doses product into the mold cavities with servo-controlled motions.
- After depositing, the vibration station supports air release and leveling.
- Filled molds can be sent to a cooling tunnel; demolding and mold return are manual operations.
What products can be made on this molding machine
This line is typically selected for molded chocolates where dosing repeatability and mold handling stability matter more than full mold circulation automation.
Note: For one-shot center-filled products, particulate inclusions (crushed nuts, crunch) are typically not recommended because they can block nozzles and disturb dosing. If your recipe requires inclusions, ask for an alternative depositor configuration.
Why mold heating and vibration are used
A mold heater is used to reduce variability caused by cold molds or changing ambient conditions. A vibration station is used to help release trapped air and improve cavity filling consistency in many products (recipe and viscosity dependent).
Auxiliary equipment
A ball mill is required for the refining process of the chocolate ingredients. A storage tank holds chocolate in a homogeneous, liquid condition and supports consistent feeding to a tempering machine. A decrystallization tube can be used on the bypass line to remelt or reset crystal structure when required by process layout.
Frequently Asked Questions
Answers to common questions about the NGOSD16SV-ML semi-automatic chocolate molding machine.
What is the NGOSD16SV-ML chocolate molding machine used for?
It is a semi-automatic molding line that combines a mold loader, mold heater, chocolate depositor and vibration on one conveyor. It prepares filled polycarbonate molds for cooling, while demolding and mold return are typically operator tasks.
Can the NGOSD16SV-ML produce center-filled chocolates?
Yes. The machine can produce plain or center-filled molded chocolates using one-shot depositing. For center-filled products, fat-based fillings are commonly preferred for stable dosing and clean cut-off.
What mold size is the machine designed for?
The NGOSD16SV-ML is designed for 175 × 275 mm polycarbonate molds and conveyor-mounted handling through loading, heating, depositing and vibration.
What is the typical capacity of the NGOSD16SV-ML molding line?
Typical capacity is 200–500 kg/h depending on shot weight, chocolate/filling viscosity, depositor timing and conveyor speed.
Why are mold heating and vibration used?
Mold heating helps stabilize mold conditions before depositing and reduces variability caused by cold molds or ambient changes. Vibration supports air release and leveling to improve cavity filling consistency.
Can the molding machine integrate with a cooling tunnel?
Yes. Filled molds can be transferred to a horizontal or elevator-type cooling tunnel depending on layout. For more even cooling, a design that supports top and bottom cooling is commonly preferred.
Are inclusions like crushed nuts or crunch recommended for one-shot depositing?
In many one-shot center-filled applications, particulate inclusions are not recommended because they may block nozzles and disturb dosing. If inclusions are required, an alternative depositor configuration should be evaluated.
