The main production equipment for producing masterbatch is a twin-screw extruder. The common production process is: pre-mixing.ingredient mixing, extrusion, cooling, cutting, and packaging. Appearance defects are a quality problem for masterbatch products, mostly related to production processes, raw material quality, production equipment, and production environment factors. Common defects include elongated particles, agglomerations, black spots, discoloration, […]

Introduction Extruders are mechanical devices that use heat, pressure, and mechanical shear to process materials. Twin screw extruders, as the name suggests, consist of two intermeshing screws within a barrel. These screws rotate in the same direction, creating a kneading and mixing action to facilitate material processing. Intermeshing Twin Screw Extruder In contrast to non-intermeshing

When using a masterbatch machine to produce masterbatches, we often meet some problems so can’t get the qualified masterbatch. For example, uneven dispersion in black masterbatch is one of the usual problems during the production process. This article introduces 2 usual problems met when using a masterbatch machine. 1.Uneven Dispersion Of Carbon Black Phenomenon whether you

The process of color masterbatch is that one or more pigments experiences concentration, activation, ground and stabilization, and then is blended and granulated with resin. Therefore, the color masterbatch should not only have good color and dispersion, but also ensure that the mechanical properties will not be damaged and it is better to improve its mechanical properties.

If you’re in the market for a dual screw extruder, there are a few things you need to consider to ensure you choose the right machine for your needs. twin screw extruders are used for a variety of applications, including compounding, reactive extrusion, devolatilization, and recycling, so it’s important to choose a machine that is

Extrusion molding is an early technology in polymer processing, which plays an important role in plastic processing. After more than 100 years of development, extruded products have accounted for more than 1% of the total plastic products.  In the extensive production practice, the theory and technology of extrusion molding have been continuously deepened and expanded; the

CHINAPLAS is one of the most significant international exhibitions in the world for the plastics and rubber industry and is widely regarded as the leading trade fair for these materials. This year, we ushered in the 35th International Exhibition on Plastics and Rubber Industries. Its influence is second only to K Fair in Germany, which

co-rotating VS counter-rotating In the counter-rotating twin screw extruder, the raw material is transported in a positive displacement similar to that in a gear pump. The speed of the Counter-rotating is lower and the raw materials shear heat is small, raw materials are not easy to decompose, thus it is not high requirements for the thermal stability of
