Currently, the screens used in extruders are mostly disc-shaped. The same applies to screen changers (hereinafter referred to as S/C). However, in a familiar example, the screens used in household sink drains were once disc-shaped, but now they are all cylindrical. At GP-C Tsuchiya, we have adopted this "cylindrical" shape, which allows for a larger filtration area and less pressure loss, with approximately 1,000 sets in operation. Why do the screens in extruders on-site remain disc-shaped? What are the advantages of cylindrical screens? We have included a comparison table between cylindrical and disc-shaped screens, so for more details, please refer to the PDF document or feel free to contact us.

The continuous backwash screen changer 'FDC60' is a continuous backwash screen changer that offers significant advantages in energy saving, resource conservation, and space-saving. Aligning the outlet of the screen changer according to the molding direction shortens the pathway for the molten resin, which helps prevent melt degradation. Additionally, the elimination of elbows due to directional changes saves space, allowing for a smaller heater capacity. 【Features】 ○ Continuous operation: Capable of non-stop production 24 hours a day, 365 days a year ○ Backwash type: Automatically cleans clogged screens for repeated use ○ Large filtration area: Minimal pressure rise due to clogging, minimal decrease in extrusion volume ○ Omnidirectional: The outlet direction of the screen changer can be selected according to the molding direction *For more details, please contact us or download the PDF.

Our company has been using "cylindrical" screens in all of the several types of screen changers we have developed over the past 20 years, and we already have a track record of approximately 1,000 sets, both large and small. Currently, the screens and screen changers commonly used in general extruders are mostly "disc-shaped," but based on the comparison results of both types, we believe that the smaller size and lower pressure loss of the "cylindrical" type are superior. 【Comparison Items (Cylindrical Screen / Disc Screen)】 ■ Outer Diameter (Size): 1.0 / 2.6 ■ Body Weight: 1.0 / 5.0 ■ Breaker Cylinder (Thickness of Breaker Only): 1.0 / 4.5 ■ Breaker Pressure Loss: 1.0 / 4.5 *For more details, please refer to the PDF document or feel free to contact us.

Our "Screen Changer" utilizes a rod rotary system, contributing to energy savings, labor savings, and space savings. During operation, backwashing, and screen replacement, there is no need to stop the operation at any time. Additionally, the high-temperature screen cylinder is contained, resulting in minimal heat dissipation. It has low pressure loss and allows for long-term continuous production. Due to its large filtration area, precise filtration with higher density screens (500#, 30μm) is possible. [Features] - Rotation is the most efficient method, requiring less power, ensuring smooth operation, and easy shaft sealing. - The cylindrical screen is the most compact and has a wide filtration area (about four times that of a disc type). - The melt flow is a mixed flow of the shaft and light, ensuring uniformity of the melt. - The orientation of the inlet and outlet of the melt flow can be selected as straight type, vertical/horizontal, or directional change type. *For more details, please refer to the PDF document or feel free to contact us.

The "FDF" is a continuous small precision filter that is optimal for small to medium lot production. It allows for continuous operation without stopping the production line, contributing to energy savings and labor-saving production. Additionally, it is lightweight and compact, making it highly maneuverable, and it can be applied to a wide range of filtration precision from 100 to 20 μm. 【Features】 ■ Enables continuous operation, contributing to energy savings and labor-saving productivity ■ Quick change of filter elements ■ Gnooning mechanism for the melt passage after filter element replacement ■ No need for replacement filter units, contributing to cost reduction ■ Orientation of inlet and outlet can be selected according to layout *For more details, please refer to the PDF document or feel free to contact us.

In extrusion molding filtration, a "screen changer" has been used for general products, while a "precision filter" has been used for high-performance molding. However, with the increasing functionality and quality of final products, precision filtration has also become a requirement for general molding. In response to this trend, we have developed the world's first "all-around screen changer filter" that can be used across the entire filtration domain. For information on the filtration accuracy and application range of the GPC screen changer filter, please download the PDF.

With the advancement of high functionality and high quality in extrusion molding, more precise filtration has become necessary. However, conventional Tsuchiya screen changers make precise filtration difficult. Additionally, polymer filters cannot operate continuously. The solution to these concerns is the screen changer using Tsuchiya's cylindrical screen! 【Features】 ☆ A unique, one-of-a-kind technology using a rod rotary method ☆ - The cylindrical screen is the most compact with a wide filtration area (about 4 times that of a disc type) - The high-temperature screen cylinder is enclosed, resulting in less heat dissipation - Due to the wide filtration area, precise filtration with a higher density screen (500#, 30μm) is possible *For the basic structure, operation, and examples of the product, please download and view the catalog.

The "FDC60" is a continuous backwash screen changer that offers significant advantages in energy saving, resource conservation, and space-saving. Aligning the outlet of the screen changer according to the molding direction shortens the pathway for the molten resin, which helps prevent melt degradation. Additionally, the elimination of elbows due to directional changes saves space, allowing for a smaller heater capacity. This is particularly effective in applications with significant space constraints, such as inflation molding, profile molding, multilayer sheet and film molding, and laminated film molding. 【Features】 ○ Continuous operation: Capable of non-stop production 24 hours a day, 365 days a year ○ Backwash type: Automatically cleans clogged screens for repeated use ○ Large filtration area: Minimal pressure increase due to clogging, minimal decrease in extrusion volume ○ Screen selection: Screens can be selected based on raw materials and molding requirements ○ Omnidirectional: The outlet direction of the screen changer can be selected according to the molding direction For more details, please contact us or download the catalog.
