Technical Details & Test Data
- Injection moulding of EPIMIX PBT/PET
Eplamid 6 GFR 15 BK Q1B502 is easy to mould material, with a very wide processing window.A few general guidelines are given here.
Eplamid 6 GFR 15 BK Q1B502 is hygroscopic and moisture sensitive, so pre-drying is recommended as a matter of rule. Material that is not pre-dried to a moisture level below 0,1 % will degrade, causing surface defects, parts that are out of dimension and brittle parts. It is recommended to dry material for 4 hours at 120°C to 130°C in a desiccant dryer with more than one desiccant element.
A few tips to ensure proper operation of the dryer:
- Ensure the thermocouple that regulates the temperature is placed immediately before the entry of the air into the dryer. There can be a significant temperature drop in the air-conveyance system.
- The temperature of the air going out of the dryer silo should not be more than 30°C lower than the air entering the system. If this is the case, you have insufficient air capacity.
- From time to time, monitor the dew point of the dry air to ensure the desiccant elements are functioning properly.
- Often, less air runs through the very bottom part of a dryer silo. Therefore, it is recommended that you take the material out of the bottom of the dryer and feed back into the top when you start up your process.
- Test conditions
Laboratory conditions are 23 ±2°C and 45-55 % RH.
- Moulding temperatures
Eplamid 6 GFR 15 BK Q1B502 can be processed between 220 and 270°C, depending on the grade used.
The following barrel settings are recommended:
Material Zone 1 (Hopper) Zone 2 Zone 3 Zone 4 (Nozzle) Unfilled Grades 220 - 260°C 225 - 270°C 225 - 270°C 225 - 275°C Impact M. Grades 220 - 265°C 225 - 260°C 225 - 265°C 230 - 275°C Flame Ret. Grades 225 - 260°C 230 - 260°C 235 - 265°C 235 - 265°C Reinforced Grades 240 - 280°C 240 - 290°C 240 - 290°C 240 - 295°C Injection pressure should generally be around 70 to 120 Mpa; this results in a minimum clamping force of the moulding machine in tonnes of 0.7 times the projected surface area in cm2.
Holding pressure is generally in the area of 90 Mpa.
For glassfibre reinforced compounds, the screw speed should be kept low, a rough indication is as follows:
Screw diameter (mm) Maximum rpm 20 150 30 100 40 70 50 60 60 50 70 40 80 35 >80 30 Back pressure should be kept to a practical minimum.
- Use of regrind
Regrind sprues and runners can be used on most materials. It is not recommended to use regrind on FR grades. When regrind is used, observe these simple rules:
- Use a constant ratio of regrind and virgin material. When a material has been processed once, its viscosity and fibre length have been decreased. Using varying rations of regrind can lead to variations in dimensions, mechanical performance and processing characteristics.
- Either feed the regrind straight back into the machine or pre-dry the regrind before usage.
- Store regrind in a dry, clean place to avoid contamination and excess moisture.
- Ensure sharp cutting blades to keep dust generation to a minimum; cut glass fibre reinforced material when it is still hot.
- Clean the grinder regularly to avoid build up of dust.
- Do not use splayed, discoloured or degraded parts and runners.
