Everyone in the plastic recycling granulator encounters a problem, that is, the shrinkage problem that occurs during processing, especially for the newly invested friends, the shrinkage problem in the processing is often difficult to deal with, and for plastic regeneration. In the case of granulator manufacturers, with the continuous improvement of technology, the production process is constantly adjusted and improved, and the shrinkage problem in the recycling of waste plastics is dealt with in the technology of equipment production, and the shrinkage of plastic granulator processing is minimized. The problem has greatly improved the quality of the product.
Plastic recycling granulator plastic recycling granulator how to solve the shrinkage problem?
Plastic granulation machining shrinkage. Cooling runner design, gate type, gate size can have multiple effects. For example, small gates such as tubular gates cool much faster than tapered gates. Premature cooling at the gate reduces the fill time in the cavity, which increases the chance of shrink marks. For the forming workers, adjusting the processing conditions is one way to solve the problem of plastic granulation machining shrinkage. Filling pressure and time significantly affect shrinkage. After the part is filled, the excess data continues to fill the shrinkage of the type compensation material. Too short a filling phase will result in increased shrinkage and will result in more or larger shrinkage marks.
