For everyday products. Complex central systems or individual units for branches such as automotive, electronics, household goods, medical engineering etc.; also for production under clean room conditions
Injection moulding processes plastic into moulded parts. The process is discontinuous and has multiple steps. The material, usually a thermoplastic, is plasticized in a cylinder using a screw, mixed until it is homogenous, dosed, and then injected under high pressure into a mould, a so-called injection moulding tool. The material cools and hardens – the injection moulding tool is opened and the moulded part is ejected.
Large quantities using different plastics and additives possible
Plastics can be separated into thermoplastics, thermosets and elastomers. Thermoplastics are the most commonly used material for injection moulding and generally have the most importance for the plastics industry. Thermosets and elastomers, on the other hand, are niche applications. For injection moulding granule-shaped polymers and compounds are processed. Additionally, regrind, masterbatches, additives or aggregates are also used. The processing of individual materials differs greatly in terms of the technical parameters, such as the temperature or the injection pressure, for example.
The goal of injection moulding is the manufacture of moulded parts in large quantities, such as bottle caps and other forms of lids, automotive or packaging parts.
Additive dosing and gain-in-weight as central systems or individual units
We at motan-colortronic provide both complex central systems and individual units from the areas drying, conveying, dosing & mixing for injection moulding. These are used in the branches automotive construction, electronics, household goods, medical engineering and packaging. Typical dosing & mixing units here are, for example, the masterbatch and additive dosing units (MINICOLOR, MINIBLEND) or gain-in-weight dosing units (GRAVICOLOR, ULTRABLEND).
