Norner injection moulding test and development centre

Injection moulding

We have an injection moulding test and development centre where our customers carry out a variety of trials, take advantage of our competence and run full development projects.  We focus on innovation and technical solutions in processing and products of plastic materials for rigid packaging and components.

Injection moulding is the most used processing technique globally and is key for most markets where plastics are used. Norner have long experience in injection moulding and application and polymer development which makes us a good partner for your projects.

 

Our injection moulding lines include:

Arburg 150kN standard screw Ø22-17D

This line is used mainly for small sample size moulding jobs which can be a result of our polymerisation lab experiments, additive recipe development or other small customer samples and has a range of moulds for standardised specimens.

Engel 600kN standard screw Ø35-17D

This line is very suitable for the moulding of a wide range of standard ISO/ASTM specimens which can be quickly changed due to the AIM Quick Change mould system.

Netstal HP 1200kN barrier screw Ø45-20D

This high performance and high speed moulding machine has a range of prototype moulds for making realistic product testing. The moulds includes; thin wall packaging cup with 380µm wall thickness, a 4 cavity tool with two different hinge design closure and 2 different inlet (2x2). Husky/Scöttli 2-cavity cap mould 28 mm neck finish PCO1810, syringe body and piston, square mouthed cup with lid.

Netstal 3000kN standard screw Ø70-25D

This line is has a range of larger prototype moulds for making realistic product testing. The moulds includes; cup, bowl and pails with lids. It also include a toolbox design with high L/D and many surface patterns which enable studies of mould filling as well as shrinkage in both flow and transverse directions.
