Currently, the screens used in extruders are mostly disc-shaped. The same applies to screen changers (hereafter 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 Tuchiya, 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 provided 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 reverse washing screen changer 'FDC60' is a continuous reverse washing 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 passage of the molten resin, which helps prevent melt degradation. Additionally, the elimination of elbows due to direction changes results in further space savings, allowing for a smaller heater capacity. 【Features】 ○ Continuous operation: Capable of non-stop production 24 hours a day, 365 days a year ○ Reverse washing: Automatically cleans clogged screens for repeated use ○ Large filtration area: Minimal pressure increase 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 various screen changers we have developed over the past 20 years, and we already have a track record of approximately 1,000 sets of different sizes. Currently, most screens and screen changers used in general extruders are "disc-shaped," but based on a comparison 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 company's "Screen Changer" uses a rod rotary method, contributing to energy savings, labor savings, and space savings. During operation, backwashing, or screen replacement, there is no need to stop the operation at any time. Additionally, the high-temperature screen cylinder is enclosed, resulting in minimal heat dissipation. It has low pressure loss and allows for long-term continuous production. Due to its large filtration area, it enables precise filtration with higher density screens (500#, 30μm). 【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 melt flow inlet and outlet 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.

In extrusion molding filtration, "screen changers" have been used for general products, while "precision filters" have been utilized 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-Round 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, precise filtration is difficult with conventional Tsuchiya screen changers. Additionally, polymer filters cannot operate continuously. The solution to these problems is the screen changer using cylindrical screens from GP-C Tsuchiya! 【Features】 ☆ A unique one-of-a-kind technology using a rod rotary system ☆ - The cylindrical screen is the most compact with a wide filtration area (about four times that of a disc type) - The high-temperature screen cylinder is encapsulated, resulting in less heat dissipation - Due to the wide filtration area, precise filtration with a higher density screen (500#, 30μm) is possible *For details on the basic structure, operation, and examples of the product, please download the catalog.

The "FDC60" is a continuous reverse-wash screen changer that offers significant advantages in energy saving, resource conservation, and space efficiency. Aligning the outlet of the screen changer according to the molding direction shortens the pathway for the molten resin, helping to prevent melt degradation. Additionally, the elimination of elbows due to directional changes saves space, which in turn reduces the required heater capacity. This is particularly effective in applications with significant space constraints, such as inflation molding, profile molding, multilayer sheet and film molding, and laminate film molding. 【Features】 - Continuous operation: Capable of non-stop production 24 hours a day, 365 days a year - Reverse wash: Automatically cleans clogged screens for repeated use - Large filtration area: Minimal pressure increase due to clogging, resulting in little decrease in extrusion volume - Screen selection: Screens can be selected based on the raw materials and molding processes - 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.
