Efficient Sprue Separation: F.lli Virginio Solutions
15/09/2025
In the injection molding industry, managing sprues is a crucial step to ensure order, quality, and production continuity. That’s why F.lli Virginio offers a range of sprue separators designed to operate in-line, directly at the machine outlet, making the process smoother and more accurate.
FV-V – Vibrating Separator
The FV-V model uses a vibration system to automatically separate molded parts from sprues of different thicknesses. Built in stainless steel, it is designed to be installed under the conveyor belt, ensuring fast and consistent separation while minimizing manual intervention.
The separating unit is made of tubes which, through vibration, allow the effective separation of parts. The tubes can be adjusted to handle different types and dimensions of molded parts.
SAB – Drum Separator
The SAB is a versatile solution, available in two versions: with manually adjustable rotating rollers or with a perforated drum designed according to specific production requirements. Its robust and modular structure makes it suitable for various types of molding, always ensuring precise component separation.
SMT – Manual Sprue Separator
The SMT is ideal for productions that require greater flexibility. Made from sheet metal and aluminum, it allows for the removal of molded parts from sprues by adjusting the speed via a handwheel. It features a conveyor belt that can optionally be equipped with either a paddle or roller system to sort the outgoing components.
With FV-V, SAB, and SMT, F.lli Virginio offers concrete and reliable solutions for all sprue separation needs in injection molding: tools that combine practicality, durability, and innovation to help businesses achieve increasingly efficient production processes.
Conveyor Belt Separators
Double or Single Roller Separators
- Double Roller: Double roller separators are designed to divide materials into two separate flows. The molded material, thanks to its more regular shape, continues to the end of the belt, while the sprues—characterized by different shapes and lengths—fall between the first and second rollers, resulting in a clean and effective separation.
- Single Roller: The operation is similar to the double roller, but with just one deviation element. Our technicians will recommend the most suitable solution based on the type of molding and the customer’s specific production requirements.
Paddle Separators on Conveyor Belt
Paddle separators represent a flexible and precise solution. Installed on the upper part of the belt, they operate with sensitivity up to a 5mm thickness difference between the parts, guiding the flow without interrupting production. This technology allows for maintaining high production line continuity, reducing downtime and manual intervention.
Application Sectors
Conveyor belt separation systems are used in a wide range of industrial fields, including:
- Injection Molding of Plastics → For separating sprues and finished components.
- Automotive → In the production of small technical parts and components.
- Packaging → For packaging containers, caps, and plastic packaging.
- Home Appliances and Consumer Goods → To manage differently shaped parts destined for assembly.
- Medical and Pharmaceutical → Where precise control of molded part flows is required.
- Internal Logistics and Handling → For sorting products in successive stages of the production line.
👉 With these solutions, roller and paddle separators guarantee efficiency, precision, and adaptability, making them indispensable tools for improving the quality of industrial processes.
