Quick-Switch system 
The QuickSwitch system, which is already patented in Europe, North America, and Asia, can automatically change the diameter and pressure class (wall thickness) of PVC and PO pipes with the push of a button on the operation panel, without the need to exchange dies or calibration tools while the line is still running. Whereas conventional production systems require the line to be stopped as well as a cumbersome exchange of die parts, such tasks become unnecessary with the QuickSwitch system. Not only is productivity increased, but the significant reduction in waste generation makes this device environmentally friendly as well. Moreover, its ability to respond quickly to rush orders also contributes to the reduction of inventory. This system consists mainly of the pin type pipe head, suction bell, sizing basket, adjustable end seal, guide pipe, haul-off machine, and cutting machine.

KMD32 type counter-rotating twin-screw extruder
Extruder for U-PVC extrusions for window profiles, etc..
The L/D ratio of conventional machines was increased from 26 to 32, to increase the specific output.
While the energy input is increased, the shear energy is reduced, improving the overall energy balance, leading to greater flexibility with respect to various additives (such as stabilizers).
As a result, production parameters can be optimized with ease when developing new products.
Further, the newly developed screw design enables optimal and automatic control of the internal temperature of the screw, improving compound homogeneity and reducing pressure fluctuations, resulting in outstanding improvements to product quality.
A strong gearbox that can withstand high screw torques is adopted. The
compact and rugged gearbox is of a low vibration type that is designed
to withstand even the backpressure of the screw. The 32D twin-screw extruder
is suitable for the production of window frame profiles, cable ducts, foam
profiles, and the production of co-extrusions.

Co-rotating twin-screw extruder
(ZE－UTX/UT series)
A gearbox of the highest standard is used to achieve high speed and high
torque operations in compounding applications, reaction processes, and
degassing processes. The surface of the barrel bore of the ZE-UTX series
is directly hardened by means of an innovative fabrication method (special
heat treatment process), so the cooling jacket and processing part are
close to each other, to achieve superior cooling effects. Further, by combining
the extruder with a melt pump, compounding and forming can be carried out
in a single process.

Foam Extrusion systems
This system consists of two stages: the plasticization & gas insertion stage, and the cooling stage.
In the first stage, a co-rotating twin-screw extruder is adopted to enable the gas to disperse evenly in the elastomer melt.
This system is used in the manufacture of insulation boards for the construction industry, foam beads, soundproof sheets, packaging materials, and food trays, etc.

PlanetCalender
The PlanetCalender is a polishing roll type calender that is ideal for the production of
clear sheets and films from PMMA, PC, PETG, and SAN compounds. Because
the positions of Roll-1 and Roll-3 can be rearranged as desired, the PlanetCalender can deliver the process engineering advantages of the standard horizontal,
inclined, or vertical roll arrangements all in a single unit.
The entire frame of the PlanetCalender can be turned to optimize the feed angle of the melt. Moreover, the resident
time of the melt over central Roll-2 can be controlled by adjusting the
position of Roll-3 relative to Roll-2. As a result, optimal cooling conditions
can be provided for a wide range of material types and thicknesses.
The melt resident time on Roll-2 can be adjusted to the type of material and sheet thickness. The feed angle, determined by the weight and elongation of the melt, can be changed by adjusting the position of the first roll.
