MuCell® process

Do you want to produce economical, high-quality components? Then you should be interested in the MuCell® process – a physical foaming technology for thermoplastics. This process offers you the economic advantage of weight reduction and guarantees the reduction of sink marks.

The advantages of the MuCell® process at a glance:

• Weight reduction of the component
• Less material used
• Shorter cycle times
• Reduction of sink marks

Multi-component injection moulding

If several components or functions are to be combined in one part, multi-component injection moulding is always a promising process. Several melts are brought together one after the other during the injection moulding process. With clamping forces of up to 10,000 KN and turntable diameters of up to 1400 mm, we excel in this area with a very high level of manufacturing expertise. Or to put it another way: almost anything is possible here.

The advantages of multi-component injection moulding at a glance:

• Function integration
• High-strength connection of different materials
• Economical production process

Insert-Moulding

In this joining process, a solid insert is pressed into a plastic mass. This can be made of metal, plastic or other materials and gives the plastic component additional properties, such as strength, rigidity or conductivity. The insert is usually inserted into the mould automatically before plastic injection moulding. The mould is designed so that the insert sits exactly in the desired position. The plastic is then injected into the mould and hardens.

The advantages of insert moulding at a glance:

• Increased strength and rigidity
• Improved conductivity
• Reduced weight
• Lower costs than with other processes; for example, when using metal components

Thermoplastic foam injection moulding

Thermoplastic foam injection moulding (TSG) is used to produce technical moulded parts with a foam core and non-foam surface layers, so-called integral foams. This process can be applied to many injection-moulded products. Thermoplastic foam injection moulding can be used, for example, to produce thermoplastic components in the white goods sector or in automotive engineering with reduced weight. However, the surface always retains a silvery structure. So if you need a sophisticated surface, the components must be sanded and then painted.

Internal gas-assisted injection moulding

This process consists of filling the mould cavity with two fluids. The first component is a liquid thermoplastic with the known viscosities. Gas, usually nitrogen (N2), is added as a second component. This flows into the core of the melt. The two fluids do not usually mix. A foam structure, as in thermoplastic foam injection moulding, is not achieved here – and is also not desired. In comparison to the classic multi-component technique (sandwich process) with two molten masses, gas as a second constituent offers two significant properties:

• negligible viscosity
• high compressibility

In Mould Labeling (IML)

This process is used to produce decorative plastic parts in an extremely cost-effective and efficient manner. A decor is placed in the tool. During the injection moulding process, the plastic part bonds with the decor. We often use in-mould labelling for customers in the automotive and home appliance sectors – for example, for dashboards, door panels, consoles and displays.

The advantages of in-mould labelling at a glance:

• high scratch resistance
• high-quality and versatile design
• high UV resistance
