Technical Details & Test Data
- Recommended Processing Conditions
- Machine - It is recommended that an inline reciprocating screw machine be used to injection mold ECP 1015.
- Cylinder Temperature - 240 - 260°C. The optimum cylinder temperature will depend upon the size and complexity of the molding. Avoid overheating and long residence times.
- Mold Temperature - 50 - 80 °C. The optimum mold temperature will depend upon the size and complexity of the molding.
- Processing and Mold Design - Injection speed, injection pressure has to be optimized for the article geometry. Typical fast injection speed, medium screw speed and some low back pressure is recommended to aid dispersion but prevent possible degradation of the material. Avoid overheating and excessively long residence times. Molds should be designed to obtain rapid filling. Multiple gates for large area moldings are recommended with the gate positioned to avoid the possible formation of weld lines.
- Machine and Mold Wear - The intensive compounding action which takes place during the manufacture of ECP 1015 ensures encapsulation of the reinforcement in the polymer. This tends to minimize wear on injection screws and molds. There is no evidence to show that ECP 1015 causes corrosion of mold steels.
- Moisture - ECP 1015 can absorb moisture therefore prior to molding please ensure thorough drying (ie, 90°C for 4 hours). Materials should be re-dried if all the material is not used within 2 - 3 hours of opening the bag. Excess moisture may show as splash marks on the surface of these finished moldings. If necessary the material should be re-dried at 80-90°C in shallow trays for 2 - 3 hours. Other forms of drying of equivalent effect are also suitable.
- Use of Re-grind - Runners sprues and scrap moldings can be reground and blended with virgin materials. Regrind additions should not exceed 10% by weight of the virgin material otherwise some reduction in properties may be experienced.
