プラスチック工学研究所 List of Products and Services

The automatic film thickness adjustment device "maku-Die Tool" can be installed on existing equipment to automate the adjustment of film and sheet thickness. It can accommodate die widths of up to 10 meters. In addition to a pre-setting function for bolt positions before operation, it can also accumulate lip profile data of molded products. Furthermore, the bolt adjustment unit can be controlled with an accuracy of 0.36 degrees, and it supports both push-bolt and push-pull bolt types. 【Features】 ■ Automates film and sheet thickness adjustment when installed on existing equipment ■ Can be controlled in conjunction with a thickness gauge or operate independently ■ Lip setting accuracy is ≦1μm (for a screw pitch of 1mm) ■ Minimizes raw material loss ■ Allows for risk management by operators *For more details, please refer to the PDF document or feel free to contact us.

It is possible to retrofit existing manual dies, and automate the thickness adjustment of films and sheets. The die width can accommodate up to 10 meters. It is also possible to link with a thickness gauge and have standalone automatic control, allowing for data accumulation that remembers the lip position during molding. It supports both push bolt and pull bolt types.

• Extrusion Machine

Originally, recycled plastic has a reduced number of tie molecules, but when it is re-melted and molded, excessive shear is applied in the current situation, leading to a transformation into a state with fewer entanglements. As a result, the molded products exhibit a physically degraded state with poor force transmission. By maintaining a static state in the molten condition and applying physical regeneration that creates a state with many entanglements through self-recovery capability, it is possible to produce molded products with good mechanical properties. We are jointly advancing a physical property regeneration process with Fukuoka University that enables pelletizing molding utilizing self-recovery capability by installing a resin reservoir at the tip of a high-performance extruder, where shear does not occur, unlike in a conventional extruder.

CNT (carbon nanotubes) have very high conductivity, and their application in conductive resin compounds is being advanced. CNTs exhibit conductivity with a smaller amount of addition compared to carbon black and graphite. By utilizing this, improvements in surface smoothness, low contamination, a clean appearance, enhanced recyclability, and excellent fluidity can be achieved. We provide a system for CNT composites using supercritical carbon dioxide.

At the Plastic Engineering Research Institute, we handle the "High Vacuum Extruder." This product features a hybrid design with a two-stage vacuum hopper and a melt vacuum venting system. By incorporating a two-stage vacuum hopper, it prevents air from mixing during the plasticization and melting process, minimizing the oxidation degradation of the resin. Additionally, it removes unnecessary low molecular weight volatile components during the melt venting process. 【Features】 ■ Achieves clean resin extrusion ■ Equipped with a two-stage vacuum hopper ■ Prevents air mixing during plasticization and melting, minimizing resin oxidation degradation ■ Removes unnecessary low molecular weight volatile components during melt venting ■ No entrapment of bubbles in the product *For more details, please refer to the PDF document or feel free to contact us.
