With the innovative continuous flow screen changers BDO x 2, the construction complexity is reduced to a minimum and the material quality is guaranteed. The new sealing system allows its use also on extrusion lines working with very high pressure levels. After successfully testing on flat sheet and pipes extrusion lines, with strand dies and under water pelletizers, and hot melt coating, this continuous technology has been more recently proposed also on blown film extrusion lines with extraordinary performance and a perfect flow continuity also on single layer lines with product thicknesses up to 10 microns. A careful engineering of the venting channels, as well as the filtration chamber, has generated the achievement of these results. A simple and effective sealing system with interchangeable components allows even complex maintenance at the customer site, minimizing downtime and costs.
BDM Static Mixers are designed to combine homogeneous flow with simple, long lasting and strong construction.
They are composed of a sequence of mixing discs drilled on a peripheral flow channel and staggered one from the other so that the polymer flow is continuously fractioned.
Several applications have shown how masterbatch leakage occurs in the best way allowing to reduce their consumption. Furthermore they have shown very good self-cleaning features and a remarkable endowment of melt temperature stabilisation.
The modular construction system allows to check the system at any moment.
They can be supplied complete with adapters and equipped with heaters. They are available for extrusion lines with screws from Ø 30 to Ø 200 mm.
Hydraulic screen changers type BDO FQ from Ø 180 to Ø 400
This new generation of hydraulic screen changer, BDO FQ, address traditional but demanding users.
They are designed in order to be fitted to extrusion lines for high hourly production or for recycling.
The new generation more similar to BDO FT has now been improved from the ergonomics point of view.
The renewed safety guards system enables easier access to the sliding plate for replacing the nets and the new wiring system allows quick and easy maintenance.
The high quality engineering of this product is confirmed through its reliability and structure and was evolved when meeting with our customers different requirements while achieving excellent results in the most critical and difficult situations.
They are available with filtering masses from Ø 180 to Ø 400 mm.
Simple and reliable, the manual BDL screen changers offer the opportunity to improve performance, at minimal cost especially on small and medium size extrusion and coextrusion lines.
Available with filtering areas from Ø 20 to Ø 120 mm, units are equipped with a self activating sealing system that allows a safe and leakproof use, up to 800 bar working pressure. The actuation lever, manoeuvrable on three sides ensures a quick and balanced movement of the sliding plate.
Adding melt pipes, elbows and adapters to our screen changers, we first introduced on the market a customized product but set on an innovative logic of standardization.
In particular, we can carry out even very complex projects of connection between extruders, screen changers and die heads using the latest engineering and production technologies supported by 3D CAD-CAM & virtual machining.
In this way we can provide manufacturers of extrusion lines a turnkey product of the highest quality.
Our range starts from ∅ 10 mm. melt flow for laboratory lines up to ∅ 90 mm. for high production rates. The 30 °, 45 °, 60 ° 75 °, 90 ° and 105 ° elbows in monobloc, as well as in two halves, allow to satisfy the most varied requirements.
Cable channels and grids for thermal insulation complete the lay-out of these components for an optimal insertion in modern extrusion lines.
BDCF hydraulic tool-die changers are designed to simplify the replacement of extrusion tools or dies in those processes like profiles where production down times are very critical.
Small size tools can be directly connected to the common customized interface of the sliding plate, while medium or large size dies must be supported by a trolley moving on rails and connected on the same way to the sliding plate.
Upstream and downstream mechanical interfaces and bolt patterns can be fully customized as well as the heating system that can be both electrical or fluid heated.
Sliding plate movement is fully protected by dedicated guards and safety limit switches.
BDCF is a reliable and efficent machine sharing many components of our BDO hydraulic screen changer range.
For more than 20 years BD Plast have been meeting our customers requirements through our expertise and innovations.
Each realized product has been conceived in order to offer our customers the best in technical performance and reliability.
Our screen changers have been developed using the latest in design technology offering the very highest Safety standards but still keeping our products very competitively priced, together with our traditions this has enabled us to continuously grow and strengthen our position within this ever demanding market.
The continuous investment and research is shown in the High Quality equipment and Service supplied and offered to our customers around the World, hence the successful results and feedback received from new and established customers that we have formed excellent working relationships with throughout our growth.
With regard to our range of Filtration equipment BD Plast supplies, you will find a series of very important features that all our products share that make them unique in certain aspects.
The product customizing level that we can offer you will show how much care we take in meeting with all your requirements.
You will notice how all our Single Plate screen changers have been designed according to a set standard and without precedent in the market.
This means that you will be able to use a number of spare parts of the same filtering mass although you are using different types of screen changers.
These are only some of the advantages that you will find when working with BD Plast, where the care taken and service offered to our customers is a source of pride and satisfaction.
