OEM partnership between drilling technology and industrial vacuum systems

Feldman ST, an Italian company active in the field of flexible industrial packaging, has chosen the solutions Coral to complete the integration of its microperforation and laser drilling equipment.
The goal: to ensure a clean working environment, protect the quality of plastic film and improve the reliability of production processes.

Who is Feldman ST

Feldman ST is a manufacturer specializing in flexible packaging machinery, with particular expertise in microperforation, macroperforation and laser perforation of plastic films.
The company also offers slitting, rewinding and printing solutions, targeting both converters and end-users in the technical and food packaging sectors.

Founded in 2018, Feldman ST stands out for its OEM-oriented approach: it makes machines that are modular, customizable, and ready for integration into complex production lines.
Mechanical precision, continuous innovation, and a focus on sustainability make Feldman a benchmark in the converting world.

The need: dust and fume extraction in the laser micro-drilling and drilling process

During the processes of mechanical microperforation and laser drilling of plastic films, they inevitably generate:

Fine dust and plastic residues from drilling the material;
Fumes and gases produced by local film vaporization in laser processing;
Mists and micro-particles that can settle on the machine's optics, sensors or mechanical components.

Without an efficient vacuum system, these contaminants cause several problems:

Decay in the quality of the perforated film (presence of residue or optical defects);
Increased machine wear and maintenance;
Risk of air pollution and non-compliance with safety regulations.

For this reason, Feldman ST has chosen to integrate a Coral extraction system into its systems that can handle both plastic dust and fumes and vapors from laser drilling, while maintaining a constant clean airflow.

The Coral solution: CA series and F series

CA Series - Modular Sleeve Dust Collectors

The Coral CA line is the ideal solution for the extraction of fine dust and solid residues.
Designed for continuous operation, it consists of polyester bag filters with high separation efficiency, suitable for even small particle sizes.

Key benefits for Feldman ST:

Modular and compact structure that can be integrated directly into the drilling machine;
High filtration efficiency of up to 99 %;
Easy maintenance and quick access to filter bags;
Plug-and-play operation, ideal for OEM applications.

The CA series effectively handles the bulk of the dusty load, keeping the environment and processing surfaces clean.

F Series - Cartridge filters for smoke and fine particulate matter

For the filtration of laser drilling fumes and ultrafine dust, Feldman ST employs the Coral F-Series line, equipped with high-efficiency filter cartridges and, when necessary, HEPA absolute filters.

Distinctive features:

efficiency up to 99.9 % on fine particulate and laser fumes;
OEM customization possibility of the number of cartridges and internal configuration;
Small footprint, perfect for on-board installations;
Long filter life and low maintenance requirements.

The CA + F combination allows for a two-stage filtration system:

CA handles coarser plastic powders;
F eliminates residual particulate matter and laser fumes, ensuring perfectly purified air.

Benefits for Feldman ST and its OEM customers

By integrating Coral technologies, Feldman ST has been able to offer its customers a complete drilling system that is safe and meets environmental standards.

The main benefits obtained:

Reduction of downtime due to dust deposits;
Improved quality of perforated film without contamination;
Increased reliability and durability of laser optics and sensors;
Compliance with occupational safety and air quality regulations;
OEM added value through an integrated turnkey solution.

Coral: technology partner for OEM suction

The collaboration between Feldman ST and Coral demonstrates how the synergy between machine manufacturer and industrial filtration specialist can generate a tangible competitive advantage.
With more than 60 years of experience in air treatment, Coral is now the ideal partner for OEMs who want to integrate tailor-made, ready-to-use extraction and filtration systems into their plants that comply with the strictest European regulations.
