how much percent of recycled material can be added to plastics? The important consideration should be end product and what your definition of "REGRIND" is. Reprocessing your own internal scrap (if kept clean and uncontaminated with anything else) is a significantly different question basis than using unknown or unclassified "regrind" from outside sources. As
injection molding issues of PC+ABS Rounded pellets usually are hot-cut, cylindrical pellets are usually strand-cut so most likely different extruders were used. This (change in extruders) may effect compounding of the materials and thus properties, but your supplier should have done QC testing to know product is the same. Again, this may be where
How to avoid sink mark while injection molding plastic products? Intuitionally part thickness uniformity is often attributed to sink marks, but most researchers have concluded that such conception is very vague or subjective! Instead it is part thickness distribution with respect to injection point (gate) towards the extreme point on the melt flow path
INFLUENCE OF INJECTION MOLDING PROCESS CONDITIONS ON PLASTIC PRODUCTS Plastic material The complexity of the properties of plastic materials determines the complexity of the injection molding process. And the performance of plastic materials varies greatly because of different varieties, brands, manufacturers, and even batches. Different performance parameters may lead to completely different molding results.
INJECTION MOLDING PROCESS FOR PP PLASTICS “Plastic properties are the basis of injection molding technology”. Mastering the technological properties and characteristics of various plastics is a basic professional knowledge that every injection molding worker must know. The performance of plastics is the basis for setting “injection molding process conditions”. It is also the reason
