3. LECTRO ENGINEERING ► The Lectro-Treat technology has been utilized to surface treat plastic parts for over 50 years. ► Adapted the Lectro-Treat technology to treat resins to enhance adhesion & improve wettibility of all types.

4. RTS TECHNOLOGY ► RTS = Resin Treatment System ► Patent Pending ► Continuous Process ► Surface Treatment lasts for 3+ years and counting

5. RTS TECHNOLOGY

6. THE RTS PROCESS: ► Adjustable treatment levels / Continuous process ► Quantifiable results  Proven QC Methods relate to performance ► Successful commercial testing

7. THE RTS PROCESS (continued): ► Significantly longer term effect as compared to past technologies  Surface properties not diminished 3 years after treatment per current testing - once you have modified the surface, you will not lose it!  Not effected by sunlight

8. Treated powdered resin put into molds Powdered resin compressed with standardized time / pressure Specific surface tension fluid added to each cube Absorbed drops indicates treatment level QC METHOD ENSURES PROPER TREATMENT LEVELS

9. LT RTS 12” High Output

10. Operator Control HMI The main operator human machine interface (HMI) screen is located on the main electrical panel. This is a multi million color High Definition touch screen that provides a full compliment of controls and monitoring of the RTS process. Monitor & Control: High Voltage – Gas Flow – Auger Speed – Faults – Resin Hopper Levels – Direct Link To Manuals & Help Screens

11. Powder Resin Hopper ► The powder hopper is made from stainless steel for long life and easy cleaning for color changes. ► The vacuum loader shown is not included, but is available off the shelf from many vendors. ► The hopper is coupled to the inner glass treating tube with silicone seals for long life and easy cleaning for color changes. ► All of the gas mixture controls are located on the operator side at bottom of the hopper main frame.

12. This shows the silicone wrap and band clamp seal between the glass tube and stainless steel hopper. Silicone has a very long life in the treating environment. The auger is powered by a VFD controlled AC high efficiency motor. The system is geared to provide a very slow rpm of the auger while maintaining mid frequency of the AC motor. This is designed for easy disconnect when removing the auger for color changes.

13. Treated Resin Discharge The treated powder resin discharges into customer supplied roller totes or can be setup to discharge directly into Gaylords. Easy access for quick change of resin containers. Covers are clear for easy viewing of the process.

14. Auger Shots With & Without High Voltage Discharge This shows the auger running through the 12” glass tube inside the High Voltage Discharge area. This shows the discharge inside the glass tube before powdered resin has been augered into the High Voltage Discharge area.

15. Auger Changeover The drive end of the auger is very easy to disconnect. The chain and tension come off and are out of the way for removal of the auger. The hopper end plate is split and slotted for quick release removal through the resin hopper. The discharge end of the auger is easily accessed as well. Pull off the “Discharge Tee” and the screw is readily available to be pulled out. The augers are very strong, but are made from light weight materials for easy handling by just two people.

16. About Lectro Engineering Since 1960 Lectro Engineering has been providing 3D Plastic Surface Treatment Systems for companies worldwide. In 2001 the company grew with the acquisition of MTM Systems giving customers a one stop shop for downstream blow molded equipment including Spin Trimmers, Impact Deflashers, Demoilers, ID/OD Reamers, and Takeaway Machines. Lectro also purchased Automation Technologies Incorporated (ATI) in 2001. The ATI division provides Custom Production Automation for Manual, Semi-Automatic, and Turnkey Automated Systems for a variety of industries. Lectro has representatives worldwide providing solutions for the plastics industry.
