Design advanced Barrels and Screw

Our technical department is constantly updating its solutions and feedbacks as a result of analysis of direct experiences of our numerous end-user costumers with daily issues to be solved or those OEMs that come to us looking for specific plastic process requirements.

For some users the screw is one of the last thing to check, for others it is the first, for a few it is clear that the plasticization process, from the polymers' sack to the finished product, is defined by a series of elements all related to each other.

Beside the most common and basic division between amorphous and crystalline polymers, during the years, because of market new requirements, updated chemical solutions in material manufacturing and compounding in addition to an increased awareness about environmental impact the materials scenario has become wider and wider. In addition, market situation decreased possibilities of having machines with “100% dedicated production” and therefore it is always harder to find a perfect balance between flexibility and optimized screw design for reaching the best performances. Therefore, at this point, only two paths can be taken: the easy one of the classic general-purpose screws or the one that brings to investigate and study the best solution in relation with the processed polymers, additives and final products to be made.

The main reason why we always suggest to try at least a preliminary investigation is strictly related with the results that using the correct screw design in injection and extrusion can be reached:
✓ Machine output increase
✓ Better efficiency in plasticizing and mixing
✓ Better melted mass and final product’s quality
✓ Reduction of cycle time
✓ Less issues colours changing
✓ Reduced consumption of raw materials, master batches and electrical energy
