One of the most common queries we receive, especially from customers in the Automotive industry, is how to carry out safe changes of materials that have very different processing temperatures on injection molding machines. In this article, we will explore the case of...
Una de las consultas más habituales que recibimos, especialmente por parte de clientes de la industria automotriz, es cómo llevar a cabo cambios de materiales seguros que tienen temperaturas de proceso muy diferentes en las máquinas de inyección. En este artículo,...
Color streaking can be divided into two categories. The first type is caused by material degradation, the second one is caused by pigments. Both types of streaks can appear spontaneously, even a long time after a colour change. We are going to refer fundamentally to...
Black specks in plastic are one of the most stressful defects for injection molding or extrusion technicians, as they may or may not have a pattern of behaviour. We know that these black dots indicate a certain level of degraded material within the system. It is...
A purging compound is a product most thermoplastic producers use to clean screws, nozzles, mold, hot runners or die of injection molding machines and extruders. These compounds were developed to reduce machine downtimes and scrap rates during material or colour...
Time flies! We just realized, we have spent the last 10 years working with injection molders to reduce scrap during material changes in the most simple way possible. Our statement when approached by production teams has always been: “ We can help you...
