Setting a Minimum quantity per order( we recommend- 200 Kg) even if it means that it’s more than one months consumption for a client.

6 implementation steps 1. Testing Eko Save to show it’s contribution for money saving. It is recommended to compare it to the competitors materials focused on: “Best Price For Performance”. 2. Training operators and management to work correctly & systematically. with Eko Save products & to follow the processing instructions completely. 3. Setting a list of rules. When clients should use Eko Save and how much to use in each case (quantity tables) 4. Working with the clients on availability of Eko Save products to the operators. It is recommended to use a “quantities marked buckets”. 5. A consistent checking system over achievements and irregular problems that are an outcome of the use of Eko Save and transferring these results into graphs. 6. Nominating a responsible operator/manager to be in charge of the subject for a period of the first 3 months at least.

FAQ FREQUENT ASKED QUESTIONS What is Purging? Let’s begin by reviewing the reasons for purging. By definition, purging is to 'undergo or cause evacuation. ' For plastic processors, purging is an essential part of the cleaning process. Done properly, purging should: v Effectively displace the resident resin. v Eliminate the resident resin in dead spots or negative flow areas. v Remove heat sensitive resins, additives and pigments which are susceptible to degradation. v Eliminate black specks produced by carbon build-up

FAQ – WHEN SHOULD YOU PURGE? This question comes up often and there are three common reasons for purging: 1. Changeover: the changeover between jobs, since purging will remove previous colors, resins and carbon build-up that will contaminate future production 2. Shutdown and Startup: are sources of degradation caused by excessive heat exposure to the resin 3. Routine Preventive Maintenance: purging can help extend the operating life of plastic processing machinery. 4. There is no necessity to purge between easy colors on short production runs.

What is the basic way of using EKO-SAVE purging products? FAQ - The full procedures of use - in each technology- are in the EKO web-sight & should be read & understood before usage. The basic way of using is: 1. 2. 3. 4. 5. To use EKO SAVE purge in a continuous cleaning routine when changing colors & materials & not as a method for dealing putting out fires. Clean the color dozer, hoper & throat well, raise the temperatures at the end of the cylinder, die & head by 20 c. Empty all the remaining materiel from the cylinder & fill the machine with EKO SAVE (1. 5 volume of the cylinder + die + head). Let the EKO SAVE purge stand in the machine for 10 minutes, check to see that the material is slowly flowing out of the die or mould. Push out the EKO SAVE purge at alternating between 20 -50% of working speeds. If the machine is still not clean return to stage number 3.

What are the big problems in Extrusion cleaning? FAQ – The most problematic areas for cleaning are: flat dies, blow molding heads, blow film dies & adaptors. Certain materials & colors may also be problematic but with the correct resin & following the Eko purge instruction you can resolve all these problems.

What are the big problems of purging in Injection Molding? FAQ – The problematic areas are usually the end of the screw, the nozzle & the hot runner. Problematic materials & colors can be a course for problems; example a machine which works with a number of different polymer resins can course degraded polymer which will be the course of burnt degraded resin. The correct EKO-purge with the instructions will solve these problems.

FAQ – How long can I leave "Eko Save" in the barrel? • We recommend you follow the purging procedures, but extended residence time will not harm the equipment, or decrease the effectiveness of EKO SAVE.

FAQ – Is EKO SAVE safe for people? • Yes. All active ingredients are completely non-toxic and have been approved by the Food and Drug Administration (FDA) for use in food.

FAQ – Does EKO SAVE have a shelf life? • EKO SAVE shelf life is similar to any plastic resin.

FAQ -Do I have to raise or lower temperatures to make EKO SAVE work better? • It is advisable to raise the temperatures in problematic areas.

FAQ – Is EKO SAVE safe for hot runner systems? • Yes. Our products can be processed through gates & hot runners. It is advisable to clean with the mould open or to inject small quantities (up to 50%) into the closed mold.

FAQ – How much EKO SAVE is required to clean an Injection Molding Machine or Extruders? EKO –PLASTICS recommends 1½ volume times of the cylinder capacity to clean the cylinder and screw. If the machine has not been purged for a long time or is old it is probable that you will need to purge with twice to three times the cylinder capacity. • In the case of blow molding heads and blow film dies we recommend enough material to fill cylinder, die and head 1. 5 volume times. • See Quantities table below.

FAQ – Can you shut down Extruders & Injection Machines on EKO SAVE? • It is recommended by us to shut down your machinery with EKO SAVE purging compound, this process will eliminate and remove all loosened and degraded colorants, additives, and plastics that may be stuck in your machine.

FAQ – What are the different purging materials & how do they work? There are basically two types of purging materials: 1. A Chemical Purge which breaks down the plastic at its molecular level there by lowering its viscosity making it very easy to expel from your machine. 2. A Mechanical Purge which is based on a resin with a low M. F. I & additives that push & scrap the resin & dirt out of the machine. 3. Purging materials are divided into liquid purge additives, ready purge mixes & compounds. 4. EKO-SAVE products are in the manly compounds.

FAQ – How do you overcome difficult pigments & burnt degraded resin? • Ensure that you work with the purging instructions fully. • Raising the working temperatures in difficult areas such as blow molding heads, adaptors, flat die extruders & hot runners. • Leaving in the Eko purge for recommended length of time. • Repeat the cleaning process twice in succession.

FAQ – Can you reuse the EKO- SAVE purge materials? • You should not reuse any purge because you are putting material which is contaminated back into the machine also the level of the cleaning concentrates whether chemical or physical have been substantially reduced.
