Micro Injection Moulding
Micro Injection Moulding is a replication technique used to reproduce many plastic copies from a mould insert.
Thermoplastics, such as PMMA, PC, PVC, COC, ABS, ..., are common materials used in micro injection. Metal or ceramic powders mixed with polymers can also be injected.
High aspect ratios (several tens) and lateral resolution down to 0,5 um can be achieved. Surface roughness depends on the quality of the mould insert.
Our system is a Babyplast.
- Dimensional precision easy to obtain . Thanks to the low running costs, it is possible to be competitive even using moulds with a low number of cavities. Layout of cavities easily balanced It is easier to balance moulds with a small number of cavities and allows to reduce the sprue size.
- Homogenous mould temperature thanks to temperature control directly on cavity plate.
- Plastification of resin without stress due to friction thanks to the unique plastification system using spheres, the temperature of the plastification cylinder is homogenous and each granule of plastic is melted by contact on hot metal. In this way, the resin is not overheated by friction.
- Low residence times in the injection unit thanks to the reduced dimensions of the plastification chamber (15cm³): the material remains for a short time at the melting temperature even in cases of small shot sizes of less than a gramme.
