Structural Foam Moulding - Lightweight parts with foamed core.
77,00 kr
This plastic moulding process produces parts with dense skin and formed core. The process allows for a significant weight reduction, with a lower material consumption, while maintaining high rigidity. The process also reduces warpage of the moulded part and prevents sink marks.
Used for:
Foam moulding is used to lower the weight of components used in vehicles, aircraft, and sports equipment.
Details:
Nitrogen gas is injected into the melt before it is injected into the mould. A solid skin is formed, and the mould core is subsequently retracted a few millimeters, which allows the pressurised nitrogen to expand and create a uniform microcellular foam structure. The typical density reduction compared with solid parts is 7 to 10 percent, but higher reductions are possible. The process can be used with most thermoplastic materials.
The sample:
We have two sample options (see the product pictures):
1. A piece of foamed polypropylene (PP) that is cut, so you can easily see the foamed core. It measures ~8 cm x ~8 cm.
2. A large tray measuring 32 cm x 21 cm.
All samples come with a laminated information card, which includes contact details for the supplier.
